How much weed can you grow indoors on 1m²?
A multitude of factors influence how much weed you can grow in a standard indoor grow environment. Click here for some ballpark estimates.
Let’s be honest; most cannabis users, both recreational and medical, have toyed with the idea of growing their own weed.
Whether it's the money or a passion for the cannabis plant that motivates you, chances are you’ll want to have a general idea of how much weed you can produce from a standard indoor grow space before diving head first into the grow game.
Roughly? Anywhere between 0 and 700g/m².
Unfortunately, a more precise answer to this question isn’t that simple. The amount of cannabis you're able to produce indoors depends on a wide variety of factors, including:
- the genetics of your plants
- the quality of your equipment
- the nutrients and grow medium you choose to use
- the actual space you plan to grow in
- your skills as a grower.
Obviously there are all kinds of facts out there. Some growers claim they’re able to produce 400 grams off a single plant using some kind of special grow technique, while others find their harvest hardly topped 1 ounce.
A general ballpark figure to aim for however, is this: as a beginner grower working with good genetics and good equipment, you can expect to produce roughly 0.5 grams or a bit more for every 1 watt of light you’re working with.
So, if you’ve got a 1m² grow space running off a 400 watt HPS light, expect to produce roughly 200 grams of weed as a beginner. Anything above that is a bonus. If you’re using a 600 watt lamp, that figure jumps up to 300 grams. If you’re using a 250 watt lamp, that figure jumps down to 125 grams.
If you're harvests are sitting below 0.5 grams/watt, you'll want to do a bit of extra research before starting your next grow. If you're getting harvests of close to 0.75 grams/watt, you can give yourself a well-deserved tap on the back.
Finally, if you manage to reach the 1 gram/watt mark or even more, you're officially ready to start teaching others how to grow.
Remember that this is a general figure. You may notice that your results are slightly above or below this, and this could be due to any number of reasons. However, 0.5 grams per 1 watt of lighting is a perfectly acceptable harvest for any beginner grower.
