Lampost:
You have a great question and like many people are saying to get an answer to the equation you have to eliminate variables. Lumens per square foot is what your looking for and you answered many of your own questions i.e. strain variations and plant numbers. I think you hit the nail on the head by suggesting to veg your plants for a longer period. Colorado has a plant limit not a space limit and bigger plants equal more dry weight. I wouldn't necessarily increase your watts (unless you can subsequently control your temperature.) Regardless of where you want to be it all starts with where you are, and good genetics are the best place to start. SUBCOOL seeds offer some of the best genes around and they are available here in Colorado. PM me and we can talk some more. I hope this helps.
illumination Reviewed by illumination on . Medical grow question... Hi guys, I'm considering a grow to cover my personal medicinal needs and wanted to get some advice before setting out. I would've posted this in the "grow" section but I've noticed that the responses in that forum aren't always that great for these types of "yield" questions. Anyway, I'm caregiver for my girlfriend as well, and a friend of hers may possibly be giving me caregiver status as well. So, I'll have 6-9 plants flowering at once and I can build a space anywhere from 9 sq ft - Rating: 5
