Wow I must have really been wasted when I wrote that. I re-read and realized I combined 2 post. Sorry.
and maybe I should explain my position, we are a local collective and part of our licensure was maintaining a pretty rigid plant count. We really didn't want to have to veg 3 weeks and definitely didn't want to increase plant counts, but we are very overwhelmed with demand and would like to supply our members. I love the hempy because we can have members tend the gardens without them having to be expert gardeners, But we have to get a system to produce more. Maybe an undercurrent in one room and hempy's in the others.
Any ideas?
I would first look at is your genetics to get an idea what they are capable of. I have seen people cry foul when their low yield Kush plants or similar does not yield as they would like. Once you establish good yielding mothers or clone in rotation you it should be easier to reach regular goals.
Then look to your grow environment. Are the temps stable, is lighting optimum, PH and nutes in check, do you clean your bulbs regularly, ventilation and airflow sufficient, humidity in check, nutrients dialed in, and the like.
Then I would look at the method of training the plant. Do you do sog, scrog, lst, combination there of and/or other techniques.
Right now I am doing 2 week veg but will soon be forced to go to 3 week veg due to flower room needing the extra week.
I have previously ran a small grow of 4 plants at 4 different sizes and I chose the 2 gallon containers over the 5 gallon containers. Its cheaper and thus far I am getting the same results as I got from the 5 gallon buckets, though the 2 gallon containers are in flower now I have not yet harvest these as of yet and have 7 weeks about to go but thus far they are identical to the 5 gallon containers. I recommend that you do similar. Just run a small test side by side to see what works best for your setup. Their are simply so many variables from grow to grow their is no magic answer I believe but lots of sound advice but use that as a guide to find what best suits your grow conditions and setup.
You will likely never be able to fully address demand, do the best you can and dont let the demand push you faster than you are prepared or you the results may not come as expected. I wholly recommend planning it out as best you can.
