By BGM ,22 Aug 2018Greetings fellow enthusiasts, Out of curiosity.... what size wattage is sufficient for a small 1 plant grow? doesn't need to be precise, just an educated, experienced opinion would be enough right now! Thanks and look forward to your replies.

By Mike ,13 May 2016You should look into the King Plus series of LEDs. A 1200 w unit runs about $212 used and is completely able to replace a 1000 w hid. I am currently using 2 800 w units and am about to […]Read More

By Kiri ,14 May 2016Robert Says "You need white LED lights.(c)". But where to buy lamps with white leds? Pro-Glow, King-Led and other listed companies still offer lamps with combiantion of red-blue-orange-white-IR leds. Thank you.

By ULL Cajun ,09 Feb 2018Amen. Find another site to bitch. An open forum @ ILGM is NOT where you go to complain! I'll give you the benefit of the doubt and assume you're honest. They state 25 business days before refunds. You're giving ME […]Read More

By Rafael ,06 May 2017So not true, first of all they claim delivery avg time 5 days, but anywhere between 5 and 25 days, if you don't get anything after 25 days to contact them. I emailed them on the 26th day just so […]Read More

By latewood.ILGM ,17 May 2016Kiri, I believe that a wide spectrum of light is better for Cannabis. White light is great. I believe you would benefit more from a wider range of growers and opinions on LED lighting, if you joined our support forum […]Read More

By latewood.ILGM ,04 Aug 2016Shannon, I do not want to discourage you but those lamps will be inadequate for growing a vibrant healthy Cannabis plant. Have you read out free grow bible? Even better yet. Join our free grow support forum and get help […]Read More

By Gangeman ,19 Aug 2016I have a male plant outside, about five feet tall. It has pollen pods. When should I harvest to get the best results, and best buzz, although I realize not the best buzz
-
By latewood.ILGM ,24 Aug 2016Gangeman, My advice to you is to cull that male before it spreads pollen around and ruin female plants. Sorry to say, male plants are not worth the time or effort to grow them for harvest. Best to start over. […]Read More

By latewood.ILGM ,28 Sep 2016Anna, I would like to help you find a cheap LED that would work but, there isn't such a thing.

-
By latewood.ILGM ,07 Nov 2016Ted, I recommend you look into Ipower digital lamp systems. I use them and have sold many to our members. The Mars hydro lamps will not outperform the digital 600w lamps, and the added warmth from the HID's will help […]Read More

By Phillipip ,08 Dec 2016Excellent unbiased opinions, one point I would pick up on is the relative costs between hps/mh and led taking into account the life span of led being 10years as appose to say a year? Then cost would be comparative. Also […]Read More

By latewood.ILGM ,13 Apr 2017Anna, I highly recommend using expanded clay. Do not use Coco. Coco cause issues that do not need to be present for growers. If you use Coco; It should be mixed with perlite. or expanded clay – I❤️GM

By Dave in ST PETE ,19 Oct 2017So I've read a ton of articles and no one seems to have a general consensus on exactly how many foot candles and/or LUX is recommended for plants under an LED. I'm fully aware of PAR and lumens, and the […]Read More
-
By latewood_ILGM ,29 Oct 2017The LED industry does not equate lumens to successful lighting. this is why you cannot find what you are looking for. LED companies "the good ones" look for leaf surface temperature, and proper light spectrum. I suggest you join our […]Read More

By latewood_ILGM ,18 Dec 2017Rosey, You started out asking about a light for seedlings. Almost all Pro growers and experts use a T5 fluorescent lamp. These are available in 2' or 4' with 2 or 4 lamps in each. A 400 watt LED is […]Read More

By latewood_ILGM ,16 Feb 2018Bob, Mirrors will create hot spots and burn leaves, possibly cause a fire, etc...Bad idea. But a roll of Panda plastic and all you reflection needs will be covered. :)

-
By latewood_ILGM ,30 Apr 2018Earl, I would check the footprint of those lights and I would also confirm that they are actually 200 watts each. Many LED lamps have are as powerful as advertised. I think you may find you need 4 more of […]Read More

By latewood_ILGM ,24 May 2018In theory, any light that interrupts the dark cycle, would be viable. You can use LED to make this happen. No worries. :) Look into foot print of lamp for necessary coverage
