Using the type of grow system you are speaking of, (I already do this, just not at this size), you need to know the production of a give species on the average.

For example I don't let any of my stuff get over 4 feet tall. I have indica and sativia genotypes, some strong in each category. I still get about 1.5-2 ounces of dried bud, never weigh out the trim, which I use for the beginnings of cannabutter.

So, at 20 plants in the flower room, if you want to continue taking out a certain amount every week, say 2 per week, then that gets you4 oz a week.

The point is, you have so many variables in plant production, size, type, veg time, etc, no one can honestly answer that question with the information provided.
WashougalWonder Reviewed by WashougalWonder on . What kind of setup is able to produce 3lbs per month? Debating back and forth with a like minded friend of mine and we both agree on alot of things when it comes to growing. We're talking/arguing about what a decent grow can produce and the costs, etc.... We are differing on a couple of things; What kind of system does it take to produce 3 lbs per month or every other month of respectable med? I say it take a nice sized hydro system or even a soil grow with at least three 1000 watt lights for flowering and three 1000 watt MH for vegging Rating: 5
