How To Setup A Low Budget Indoor Marijuana Garden?

In this article we will cover:

Many people want to start growing marijuana but don’t have a lot of money to buy all the equipment. Here’s a list of the most important items and what I would recommend. It is possible to set up a cheap indoor marijuana grow room. Marijuana plants need light, water and co2. Also, the temperature should not be too low or too high and a little fertilizer is needed.



Setting up and using your MH HPS cannabis grow lights

The most important and also most expensive item to buy is the light. You should buy a 600-watt High Pressure Sodium (HPS) light. It will cost you around $30,- but it will pay for itself after one harvest. Experienced marijuana grower yield up to 21 oz of marijuana  with one HPS 600-watt light. Of course all the other circumstances should  also be perfect but still, an inexperienced grower with a cheap set up can yield 4 to 8 oz with one HPS 600 in 3 months. You can use fluorescent lights but the yield will be less.


Watering cannabis

Just use regular tap water. If you can drink it so can your marijuana plants. Professional growers use corrected water with pH between 5.5 and 6.5 and EC between 1.8 and 2.2. There are 3 common methods for testing these values, but it will also work fine with regular tap water. Use some nitrogen (N) during the growth phase and some N-P-K during flowering. You can find this at your local garden center or get them from


Raise co2 levels indoor weed

All green plants, marijuana included, use light energy, water and carbon dioxide (Co2) to produce energy in the form of sugar for its growth (photosynthesis). You can use a Co2 tank with a regulator but you can also install a simple ventilation system to refresh the air in your grow room. Place a fan in front of the air-inlet and create an opening (as high as possible, hot air rises) where the warm air can escape.

The ideal temperature for cannabis plants

The temperature should not drop below 64 and not get higher than 86. Around 77 is perfect! The HPS light will produce a lot of heat so if you install it in a 1x1x2m closet without ventilation temperatures will rise up to 125. Use a little more space and temperatures will be fine. All plants should move a little by the air flow in your grow room, just like the wind normally makes plants move.

Use aluminum foil instead of mylar or other reflective foil. Buy used equipment and be creative. See how you can set up a simple homemade hydroponics  system. You don’t need a water pump, a bucket or watering can will also do. Also, you’ll need to read a lot about growing marijuana,

Of course you need some high quality marijuana seeds! Check out our seedshop  for a wide selection of top-quality seeds. Please leave comments or questions below and don’t forget to download my free grow bible.

I have a room 6feet wide 11.4 feet long.and 7feet high.What do I need to fill this area?

By MacGyver Stoner on 13 April 2014

Do you mean to fill the area with light? You should set up the room as two squares instead of one long rectangle, like two approximately 5 foot wide by 5 foot long square areas and center a 600w HPS centered above each square. You could get away with two 400w HPS but your yield would be lower and even less with fluorescent lights.

Are you kidding? use tinfoil instead of mylar? It creates hot spots and is a poor poor reflective material. White paint would be better than tinfoil.

By kinetic on 12 October 2014

yes I would also like clarity on the tinfoil as it has always been said one has to avoid using this. I find it strange that Robert would just recommend tinfoil with not a proper explanation.

By ClaireILGM on 14 October 2014


Tinfoil can certainly be used. It does not create hot spots and is actually very reflective. The down side is its very conductive (so watch out with electricity) and it tears easily.. For a simple closet grow its perfect.

Use panda film white side goes inside black on the outside works great

By Ron on 10 October 2014

Robert, If you haven’t done so already I hope you post this article on The Weed Blog. I’m having a discussion with someone about the feasibility of cheap growing. I’ve done it and it worked for me. We both agree that research is necessary before growing as there are many considerations before dropping seeds into the ground. BTW, I’m an outdoor grower, so your tips here don’t apply to me, but many novices should find them helpful.

Cheap growing don’t get the yield. I bought grow box it’s perfect. Robert the master at genetics

I have been experimenting with auto flowers this last past summer and the most I’ve got off of them was about 4 to 6 ounces the least of God was probably an ounce and a half I can’t believe these things are so quick to one summer I’ve arty done four harvest’s I just want to say that I definitely think on the autoflower does have a place in the mayor seed Industry

I would say NEVER use aluminum foil, and avoid buying 2nd hand stuff too. Keep your grow area clean,

By Rick from Co. on 8 July 2016

I have always attached emergency space blankets to my walls for reflective material. They are cheap and work great.
