How Much Marijuana Can I Yield Per Plant? A Pound!

How Much Marijuana Can I Yield Per Plant? A Pound!

One of the most popular questions regarding marijuana is “How much marijuana can one plant produce?” or “How much will a 600 watt HPS yield?” There are no simple answers to this question as each situation depends on a number of variables.

Many people take up growing weed and they have a variety of reasons for doing so. In every case, you want to get the most out of your crop. Whether you’re growing for medical reasons or you just want to make a little money on the side, the overall yield is a top priority for all growers.

Maximum yield per plant indoors

Lights are of the utmost importance when you’re growing indoors. Experienced growers can produce about a gram of marijuana per watt of light (1 gram = 0,035 oz). So, a 400-watt HPS grow light can potentially translate to 400 grams or 14 oz of dried, usable cannabis.

Likewise, a grow room with 1200 watts of light can yield 1.2 kilograms or 42 oz of cannabis. Having the right equipment, adequate nutrient solutions, beneficial air quality, and other valuable
factors is important for producing the highest yields possible. Making sure the plants have space to grow is also key. Beginners can expect to yield grass as follows:

Marijuana yields in imperial measurements

  • An average of around 1.5 to 2.0 oz  (3.5 oz for advanced growers) with 200-watt CFL lamps in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft.
  • An average of around 3.0 to 5.0 oz  (9.0 oz for advanced growers) with a 250-watt HPS lamp in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft.
  • An average of around 4.5 to 9.0 oz (14 oz for advanced growers) with a 400-watt HPS lamp in a grow room that measures 3.5 x 3.5 x 7 ft.
  • An average of around 5.0 to 10 oz (21 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 4 x 4 x 8 ft.
  • An average of around 9.0 to 18 oz (36 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 5 x 5 x 8 ft.

Marijuana yields in metric measurements

  • An average of around 40 to 60 grams  (100 for advanced growers) with 200-watt CFL lamps in a grow cabinet that measures 1 x 0.5 x 2 m
  • An average of around 80 to 150 grams (250 for advanced growers) with a 250-watt HPS lamp in a grow cabinet that measures 1 x 0.5 x 2 m
  • An average of around 100 to 250 grams (400 for advanced growers) with a 400-watt HPS lamp in a grow room that measures 1 x 1 x 2.5 m,
  • An average of around 150 to 300 grams (600 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 1.2 x 1.2 x 2.5 m.
  • An average of around 250 to 500 grams (1000 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 1.5 x 1.5 x 2.5 m.

How much does one marijuana plant produce

Indoor growth doesn’t bring with it a lot of certainty in terms of yield per plant. If you have only four plants per lamp, then you’ll yield much more than you would with total of sixteen plants for every lamp. You should consider these things prior to choosing how many plants you want to grow:

  • If you’ve only got 4 plants, your crop will be ruined if even one gets a disease or dies
  • Vegetative growth lasts longer with only four plants. You should want to force flowering when the tips of the leaves are touching. If there are more plants, the leaves touch quicker.
  • Four plants are easier to manage than sixteen.
  • If someone catches you, you only have four plants to your name.

Either way, growing four plants using a 600-watt HPS lamp could yield about 150 grams or 5.0 oz per plant. Sixteen plants that are grown under a 600-watt HPS lamp could produce about 37.5 grams or 1.3 oz of marijuana per plant. And if you only grow one huge plant per  600 watt HPS it could produce a pound of marijuana per plant!

How much marijuana does one outdoor plant yield

Under perfect conditions, you can expect yields to extend to 500 grams or 17.5 oz of marijuana per plant. Space is a necessity (at least two meters) along with water, nutrients, and a dearth of pests and diseases. If you use containers, they should be at least 50 liters or 15 gallons in size. It’s a good idea to germinate the seeds early on to allow the plants time to grow large. It’s best to germinate indoors where you can manage the humidity and the temperature for the seedlings. Again, 500 grams (17.5 oz) per plant is possible if everything goes as planned.

Aside from an adequate amount of sun, water, and nutrient quality, the actual genetics of the plant play a very important role. Seeds are vital and you need to have some exceptional seeds at your disposal. You can look through our cannabis seed shop to find the a strain that’s right for you. It all starts with genetics….


The difference in weight of wet and dry weed

Drying your weed slowly (10 to 14 days) in a climate controlled dark and dry place with a temperature of around 64 degrees will get you more weed in weight.

You will get about 20 % to 25 % out of your wet weed after drying, depending on the strain, the density of the buds and the way of drying. Only weigh the wet buds and not the whole plant.

Out of a well cultivated Sativa you will get approximately 20% -22% dry weed and from an Indica about 22% -25%. So out of one pound wet Amnesia Haze you will get approximately 7.4 ounces and if you dry one pound of White Widow you’ll get about 8.4 ounces. At a street price of $ 7 (Oregon) or $12 (Texas) this is very good profit.

You will end up with approximately 12.5% ​​ if you weigh the entire plant, including stems and leaves, while it’s wet

epic article !!

clear even to me 🙂

just can not understand, what distance should be between plants?
How many of them do you have on picture nr. 7 ?


By ilovemarijuana on 24 February 2013

Hi Andy,

There are only 5 plants in pictures 7-9. All the branches that come through the screen are gently bend and tied to the screen with tie wraps. This is called the scrog (screen of green) method. I’ll write an article on how to scrog next week.

Robert


By Andy on 24 February 2013

It is amazing. I just wondering and can not understand, how you manage to get such big buds which are almost like the main . (actually hard to say where is the main and where is a branch)

also three additional questions 🙂

1) What is the distance between plants ?

2) How many extra buds in average your plant has ?

3) What is room size ?

P.s will be impatiently waiting for “how to scrog” article 🙂

thanks


By ilovemarijuana on 25 February 2013

Hi Andy,

There are no rules for the amount of plants etc. Did you get the pictures i sent you? Thats 5 plants in a 3 x 3 foot container. And because the plant doesn’t waste any energy on small, useless buds you get 5 to 10 huge ones per plant.

I’ll keep you posted about the article

Robert


By Andy on 26 February 2013

Yes, I got them. Sent you back mine. Just don`t be scared 🙂

I suppose, I would have many questions about your article. Waiting with impatience, because new plants are coming after about a week.

Want to try implement what you are sharing .

thanks



By Laura on 10 April 2013

Hello

I,ve been reading your articule and it is fantastic!
i only have one question about the lights, due to the space i am able to fit for growing marijuana i can only use fluorescent bulbs. i just germinated 5 plants and i am using 2 bulbs of 105w each (in fluorescent light, wich would be like 420w of an incandescent bulb, so I asumed Im using 840watts of light). so the question is; how much gr per watt will the plant yield, using 840w in fluorescent bulbs?
Thanks in advance!


By Robert Bergman on 11 April 2013

Hi Laura,

I think your fluorescent lights can yield 50 to 100 grams at best. Fluorescent lights are perfect during the vegetative fase but not the best option for flowering. Instead of two 100watt fluorescent lights you can also use one 250watt HPS bulb. One 250 watt HPS bulb can yield a maximum of 250 grams.

Robert


By Zach on 4 November 2016

I just switched to led lights kinda as an expirement my plants are just starting but I was wondering if leds are a good or bad idea


By terry on 30 April 2013

Must you use metrix? I can’t spell it let alone convert it. thank you


By Valentino K on 17 October 2015

The whole world uses metric (not metrix) except you silly Brits and Americans, instead of rejecting it why not just learn it. You’ll see it’s much easier than the standard system, everything is in increments of 1s 10s and 100s. And everyone knows there’s 28grams in an ounce, just divide the total amount of grams given by 28 and you get your ounce equivalent, don’t see what’s so difficult about simple division. Great article btw Robert!!!


By Pete on 15 November 2015

To be fair, in English at least, bud prices are traditionally quoted in imperial; the ‘gramme’ is a more recent creature of retailing it at a very petty level; the customer’s choice is between a gramme or seven grammes, or quarter ounce, which might cost four or five times as much. It’s just a nice heritage thing for an enjoyable part of life; like twenty or sixteen ounce beer pints sit either side of the internationally most common 500mL.

On the other hand, crystalline drugs seem to have been in metric for decades, even in the States. With cannabis for medical purposes, the more scientific-sounding 5g unit seems to be used in the US, just as 10g is used in Uruguay.


By charley on 3 June 2016

We know what grams are we do use metric just not for drugs in America not so much but in uk most things are metric ok


By Daniel Yingling on 18 November 2016

We Americans use both every day. With Marajuana we typically use grams and Ozs. For our dispensing. I’m older and this is the way it’s been done since the 60s.


By Blazer on 15 July 2013

Using Fluros or Energy saving bulbs for the veg stage and to propergate cuttings its ideal.. if u want big vigirous plants i suggest swapping over to a Hps Or Mh Bulb they have enuff grunt to penetrate the canopy and get some big colas growing.


By jodie putilla on 16 July 2013

Thanks .im a new grower and i have gained a lot of info from you guys .thanks i’ll be back for more ..thanks again. Jodie.p

I have a 2 foot plant outdoors, i wont
to know if I con start putin a lite on it at night to veg more


By erick on 28 July 2013

i have a place 2 m, 2m. how can i grow in this place


By Loony on 26 May 2016

Hi Erick. If I have read your question correctly, you are asking how many plants you can grow in a 2m x 2m space. I don’t know if this will assist you or not. My last grow I grew, 32 red devils & 8 White Rhino’s in a 3m x 2m space under 6 x 6oo Watt HPS & one 1000 Watt HPS. This yielded just over 200 oz’s (I’ am old school so my Oz’s are weighted in at 30 grams each) of dried plant that were on a 18/12 light cycle. 2 months on grow, 6 weeks on flower, plus two weeks to dry correctly. Hope this helps in your calculations.


By Maziar on 24 August 2016

Hi Mr loony,

I have some questions about cannabis growth and would be grateful if you could please guide me.

Best regards

Is the sour diesel strand/ seeds good for a beginner grow ? And if not what do you suggest ? Don’t have much space.


By Albaro G on 14 January 2014

hi, I found your article very interesting. It did leave me with a question though. if we were to use a grow room of 3x3x6.5 feet with only 2 plants, would the wattage still make a difference in the amount of buds that would be produced? I guess what I am trying to ask is that if I am planting two plants, would 400 watts give it all the light that those two plants will be able to take or will having a 600 watt lighting system still be beneficial for a cultivation as small as 2 plants compared to a 400 watt lighting system?


By jim on 18 January 2014

do some real research you believe any of this article it is totally unrealistc


By ataxian on 21 January 2014

What about super cropping?

One plant medical grow super cropped is better than scrog!
Scrog maybe good for commercial growers however supper cropping is more efficient for personal growing for medical conditions!


By james on 21 January 2014

Robert,
I love reading about the potential these wonderful plants have. But it pains me that I’m not getting the results as such. I consider my self above a begginer but not yet an expert. Wondering if u can help me isolate the problem with my grow affecting my yeild. Thank you


By Cartel on 21 July 2014

Veg 2 plants for 6-8 weeks and you will have a qp easily


By budhunter on 22 January 2014

hi great reading 4 a none reader just 1 ? when u r chatting about how much bud 1 would get per plant r u taking about the weight when 1st croped or when its dryed out thanks keep up the great work. budhunter


By Cartel on 21 July 2014

I get 2 ounces per plant , I veg for 6-7 weeks


By Edwin Smith on 8 April 2014

Hey what’s up! Edwin Smith here I was wondering if you could answer some questions for me. I have a XXL13 Four-site current culture system with 600w KIND LED’s over each module. I want to main-line and FIM my plants in a 6.5×6.5×6.5 tent with a chiller and a active air temperature controller. I was wondering if there are any special nutrient mixes that you can let me in on so I can have an idea of some new techniques for my grow. Been doing this for about seven years now just want to get out of the normal. Can you help me just send me an email I know its hard to get to everyone. Let me know what’s up.


By RIDGEBACK XTRM on 11 June 2014

What about if you use 8 VHO florescent lights, four blue and red. Will that increase the yield for growing indoor to the advertise yield? Yields only 1 to 3 oz. per plant is not acceptable in my opinion!


By dnvest on 20 June 2014

Thank you very much for all your help, Robert! This is my 3rd year growing outdoors, but this year I have more plants. (8) And they all seem to be growing at different paces, each one unique though from the same strain of seed. (Medijuana Feminized) Strange. And just as in the previous few years, I’m basically winging it. lol! But I have to say, WORM CASTINGS do wonders during the earlier stages. Is there anything wrong with using mainly worm castings & a little Miracle Grow watering from time-to-time until the flowering stage begins? Thanks


By Cartel on 21 July 2014

That’s ok buddy I use caterpiller sprays directly onto the buds nothing bad will happen. The clients can’t tell I used pesticides


By Cartel on 21 July 2014

You guys are all dumb, I use a 400 watt hps , I yield anywhere from 8-12 ounces easily , veg for 6 weeks with 8 plants and you will have a pound in 4 months+drying+curing


By Anthony on 14 August 2014

To all the brave men who went into Gaza to all who fell.


By Dan on 4 September 2014

I get 5 ounces or more on each of my plants I grow 16 in an iws flood and drain system under 4 X 600w lights in a tent that’s 2m X 2m X 3m. Veg for 8 weeks flower for 1 week. I haven’t tried the monster croping yet I might give it a go to increase my yield but my physco plants are quite bushy anyway.


By kaligrows on 22 October 2014

Light spacing….genetics and lumens=great yields!


By chrissy on 1 January 2015

Hey Robert! Reading your emails daily now for months and I’ve been growing for a yr now _


By chrissy on 1 January 2015

Wow so comment didn’t work. 150 watt in a closet measuring 32 long 25 deep 60 high is this going to give me more then a couple ounces for one critical jack herer almost 2 weeks in the switch vegged for almost 3 months trying to get more then 2 ounces..


By george on 11 January 2015

can u recommend a bloom booster Thc booster grow booster


By gary mendel on 26 January 2015

been growing for 10 years , but still not getting yield u talk about , I use 1000w and ocean soil , veg to 3 ft tall 10 plants per light, yield is only 3/4 pound, not sure what is wrong but article did not offer much info on conditions in room and genetics


By Robert Bergman on 27 January 2015

Hi Gary,

With a 1000 watt light bulb you should be able to yield 2 pounds if the conditions are right. There must be a limiting factor. Is there enough CO2 in the air? Enough water and nutrients? What are the pH and TDS levels of the water? And what are the temperatures during the day and during the night? Maybe you can open a thread on the support page and tell us some more about your setup?

How much can I expect from white widow if I have a 250w Hps and two 125 Cfl light on the sides of the plant?


By Chaos on 11 February 2015

sorry *plants, growing 4 that is


By Indica Bob on 26 February 2015

I’m growing 4 plants that I will germinate under a 125 att cfl and transfer outside in 3 weeks. At week 8 ill transplant into 45 gallon buckets. They will be under constant direct light and the will get the proper amount of nutrients.


By Jared on 5 March 2015

I know CFLs are good for vegetative growth. And I keep hearing about MH and hps bulbs. But I’m looking into a fully assembled grow box for stealth and they have CFLs and LED lights. But I don’t see LEDs mentioned in anything else I’ve read. So any info on growing with those?


By ken on 17 March 2015

led’s save power and have a very low heat output and you can grow some good smoke under them it just takes longer with them so in my grow i have a mix of m h lights and led ‘s and have great plants {50/50 each type} and it cut power use and heat output,my room with all led’s when finished is going to mixed lights


By Ocea Rice on 28 August 2016

Why? LED is beyond capable to produce quality mj plant from seed to harvest, sovwhy the B’s concerning; LEDs!? Your answer please… And doesn’t need 2include; I, or a business sooner, or buddy sell MH, SPL as your rational for propagation of ‘your’,choice of commercial market technique, you know FACTUALLY… most areb ‘small’ independent growers for their supply, period… why the Allegiance to the money whores?


By Dankmike on 23 March 2015

all of yall are lucky u are growing i have yet to even find a secret place to grow outdoors or indoors i am have 5 years in growing. my first indoor grow was a White Widow plant would like to order some of your special deals in seeds robert will let u know when i order


By rick on 14 May 2015

looking for a good seed source


By Jennifer ILGM on 18 May 2015

Great you are at the right place, just go to our shop!!


By Ridecosnow on 24 June 2015

My first indoor grow I harvested a lil over an lb on 6 plants, for second run I used clones from exact same plants, but bought a water tester and was testing at over 800ppm! I spent $80 on a water filter that brought my ppm down to 14! My second grow yielded over 3 lbs dried just from giving them clean water. Also many things in hard water are also in your nutrients, and fertilizers, so in my case they were getting too much. Working on my first OD grow right now, started from seed, and build my own soil, trying different placement of plants, 4 in the ground but u dug out a 4’x4’x4′ whole for each plant and replaced it with my own soil. They look really good, just not growing as high as I’d expected. I put them in the ground about 6 weeks ago after they’re root ball was strong enough I felt for them to be left outside. They’re about 18″ tall after 6 weeks in the ground, is that normal? I might be over watering them, the soil that I didn’t replace is very full of clay, and drainage I’m worried about. I’m in CO, so we have high heat, and low humidity, too, how often should I be watering, and how much water for that size of hole? Great site, and great tips! Thanks!


By latewood on 24 June 2015

Sometimes plants do not grow as tall under intense light. Buds get tighter though. Clay is generally full of nutrients and drains fairly well. You should be OK. Please join our support forum if you want faster responses, and more opinions from our expert growers.

By Greg on 19 August 2015

Have you used LED lights? What is your opinion on them, besides cost.


By kbk420 on 20 August 2015

My grow space is 25” deep 88” wide 65” tall. Im getting 4 300 watt led grow lights. Completely white, great for reflection however I can not decide if I should grow five plants and train them or grow several smaller plants. I don’t want any of the light wasted so which is the better option Robert?


By latewood on 21 August 2015

Hello Greg,
My opinion on LED lamps is: I do not use them. I use digital ballasts. I know growers i respect who love LED lamps and claim they grow just as much yield as HID lamps. I am not sold on this, without having done a side by side. If you join our support forum, you will run into some expert growers who can give you more insight. 🙂


By latewood on 21 August 2015

Hey kbk420,

Sorry my friend. This is a choice you have to make. It is a concerted opinion of most old school growers, that no matter what method you use, the yield will be close to the same, unless you really mess up one method more than the other.

Best advice I can give you is to; Review the type strain you plant to grow. A “Sativa” may be better of being trained due to vigor and potential height; While an Indica, or Auto flower can be grown straight up, because generally, they grow shorter. Once you understand the potential grow characterisitcs of the genetics you are going to use; You will be closer to finding the answer to your question. Happy Growing 🙂


By Otubu on 28 August 2015

Very great post. I simply sbtumled upon your blog and wanted to say that I’ve truly loved browsing your blog posts. After all I’ll be subscribing to your rss feed and I hope you write once more soon!


By mallik on 27 September 2015

Hi rob,cheers for looking after us,I downloaded one of your book and it’s a pleasure,so keep up the good work


By 420ZSX on 14 October 2015

Don’t hyperventilate over not getting the indoor quantities mentioned here. They are top end estimates if you are an expert grower and everything goes off without a hitch. These are yields to shoot for but not get all disappointed if you don’t achieve. Just enjoy the bud you grew.

Something got lost in translation in that last section of the op. It only makes sense if you count 32oz in a pound, so cut those dry estimates in half. I guess the prices are per gram? Confusing. Overall good site, though. Keep up the good work.


By Pete on 15 November 2015

Thanks for the heads-up on the maths. I like maths, but I forget to do them sometimes. That should be especially enjoyable for North American brethren, who don’t say maths very intuitively.


By Dennis on 26 October 2015

Hey Robert!
Thank you for your emails…I’m gathering information to do my first grow…being on a fixed income I have to do it in steps. It is truly amazing how the marijuana helps me cut back on my pain killers I need to take to get by each day. My question today is about using LED lighting. Are they good for growing(read different thoughts from everyone. I have a grow tent that’s 9sq. ft. How much wattage will I need for the space, and how many plants should I start off with. Looking forward to not paying extreme prices, usually get real harsh commercial. It’s what I can afford since inmy area anything that is really good goes for around 20 bucks a gram. Thanks for your help!


By Pete on 15 November 2015

Your comment really made me laugh, because for some reason I couldn’t help imagining you as a seventeen year old pretending to be a senior to cover himself for self-incrimination or something.

Read at face value, though, your comment also makes sense. So double thanks.


By latewood.ILGM on 29 October 2015

Hey Dennis,

Robert is always glad to help.

As far as how many plants you should grow in your tent You did not mention what genetics you planned on growing. If I get your dimensions correct you have a 3’x3′ tent. I would go with no more than 4-6 for your 1st grow. It is better to have a little airy space and healthy plants, than it is to cram too many plants in a small space, causing environmental issues. As you become more experienced; You will be able to add more plants and incease your yields.

I am on a fixed income. I know what it takes to put together a quality grow system on a small budget. For that reason, I recommend that you buy a 400/600 watt Ipower switchable digital ballast. LED is expensive, and the digital HID lamp is more versatile and provides more bang for the buck.

It would be great if you joined our Support Forum. Look me up when you get there. Happy Groweing


By Leon on 3 November 2015

By Pete on 5 November 2015

Does anybody have experience with using a “Earth Box” for their grow?


By latewood.ILGM on 9 November 2015

Pete,

I have not used the Earth Box. However; If you sign up to our Support forum, I am sure you will find many members with experience with that product.


By Nelz on 28 November 2015

Nice video. Very informative. Ive been growing legal medicine for the last seven years. I recently was forced to switch to a 10x10x8 grow tent. Im currently running 3000 watt hps lamps with three plants per lamp that were veged for 5 weeks. Do you think 3000 watts is overkill?

Thanks
Nelz


By Nelz on 28 November 2015

I actually have a fourth 1000 watt lamp in the room, just haven’t fired it up yet.


By latewood.ILGM on 30 November 2015

Not at all. I have to assume you are using 3 – 1000 watt lamps. Max. coverage for those lamps in general are 6’x8′, but overlapping the footprint would give you better results; As long as you can control the temperature.


By latewood.ILGM on 30 November 2015

Nelson. I do not see a reason to add a 4th, but if you fell the need, go for it.


By greg on 17 December 2015

I am new to this and plan to plant my first crop I have been reading a lot of information on growing and I have 1question be for I start germination what is the best way to germinate for indoor growth


By latewood.ILGM on 19 December 2015

If you are growing indoors in soil; Use a jiffey pellet to propagate your seed

If you are setting up a hydro system, then use 1.5″ rockwool cube.


By EDOG on 19 December 2015

Generally, 0.5 grams per watt is more realistic. Also, you get a better ratio of yield/wattage as you go up in wattage, i.e. you’re more likely to hit 1 gram per watt under a 600W or 1000W HPS than a 250W or 400W. That’s because HPS lights are more efficient at higher wattage outputs.

As for the outdoor stuff, medical growers in California that are limited to 25 plants are often pulling 6, and sometimes up to 8 pounds dry… from a single plant! Of course, this involves expert plant training, gardening, not to mention the near perfect conditions that the Californian coast provides.


By JAH on 6 March 2016

In regards to outdoor potted plants,

If you plant in 1 yard of good quality soil, get them vegging early inside before planting outside and then keep on top of nutrient input and overall health and training, with plenty of sunlight, you can expect to get between 2-4 lbs per plant, depending on strain. If 2 yards, double that. Ive seen 10 lb plants if all the conditions are just right.


By devon on 11 March 2016

Hi i am a first time grower, i have a 3×5 grow box that i made… I also have a 250w CFL, i plan on growing 3 or 4 plants….. My question is do i have good lighting for a great harvest?
Desperately in need of help

I have a 60×60×80 size grow tent. 1 300 watt led light 1 45 watt led light and a 400 watt hps light. With 5 plants out of 6 remaining after take the male out.i am a first time grower nd im still not sure how to scrog yet ive seen plenty of videos I have 1 plant thats almost 4ft tall and its about 10inches away from the hps lamp while the others are about 2ft away from all the other lights how far should the tall plant b away from the light during the flower stage I am now 2 weeks into it and they should stop growing now right?

Mike,

Different strains grow at different intervals. There is no perfect formula.

You will need to keep lamps 24-36″ from canopy depending on how hot the air space between the lamp and canopy is.

Best to think about training your plants.

Best thing for you would be to join our support forum. Many growers have become experts at SCROG, and are will to guide you. 🙂

devon,

You will do OK with a 250w CFL. It is a bit under powered but, will allow you to grow successfully without heat issues.

If you want a bigger harvest; You will need to invest in more lighting, and exhaust systems to manage to heat and humidity. 🙂 lw

I’m planning on buying the set to grow along with seeds and I read that you can get more from one plant than you can with 4. Which would you recommend?


By latewood.ILGM on 21 April 2016

Marilu,

growing is a series of personal choices. This is one of them. It all depends on how much space you have. It also depends on your grow experience; The quality of environment you produce for your plants, and many other variables.

Perhaps you would like to join the ILGM supprt forum, where we have many knowledgeable members and staff to help you all the way through your grow 🙂

Happy growing

What about led lights. Any thoughts?



By stephen on 9 June 2016

I’m a first time buyer and grower,so much great info here, I’m filling up a small note book. Just ordered Fem. white widow and plan to grow out doors upstate N.Y. wont even be able to plant until late June so this should be interesting for grow to harvest time , I”ll have about a 10-12 week window if my seeds arrive as scheduled.
My question is that if I don’t use all my seeds ( I only plan on planting 3-5 plants) how do I store seeds for next year


By fishhead on 29 July 2016

Im limited on my hieth for my light & can only grow (space enough for 2 plants). my question is how can I make it work with a 3x3x4 or 5?? reduce the 600 watt to 250 & try to bush them instead of growing tall?? thanx ..

stephen,

Place them in a cool dark place or in the door of you “fridge” behind the salad dressing. 🙂

fishhead,

You need to read up on LST or SCROG method of growing. Download and read our Free Grow Bible. Or; Join oursupprt forum. 🙂

Are the led grow lights worth using? Just starting my grow operation though they might use less electricity. Heard they were very good but not sure this person knows what he’s talking about. Thanks


By Roy ILGM on 11 November 2016

Hi Troy, from what we’ve seen they may yield a little bit less than HPS but it’s almost negligible when grown right.


By Mark on 20 November 2016

Just set up my grow room with a 1.5m2 x 2.4m2 x 1.8m2 tent, it’s got 2 600w hps lights, an outside air source located at the bottom left hand side and a 147mm extraction vent fitted with a 24omm x600mm carbon filter. It’s temperature and humidity controlled with 8 kush plants. My first grow but I’ve got plenty of help from experienced growers plus I used to grow show tomatoes. What do you think my yield should be roughly ?
Thank you in advance.
Mark

I plan on growing with leds for the next time can you refer a cost effective one and if you have one kind goind and getting ready to flower is it unwise to add more light of a different kind? Or does it hinder growth….


By Mark on 20 November 2016

Should of said also that I’m going to lollipop them and supercrop them as well as top them, they are on a 18hr light sequence at the moment then switching them to 12/12 hr.


By latewood.ILGM on 22 November 2016

Mark,

Yield is not predictable unless you have an established benchmark that would be needed to make an informed guess. Otherwise; It is just a guess.

The yield depends on the skill of the grower, and the methods, time, and investment put in to provide an optimum result 🙂

Happy growing, And; You won’t know until you grow!
