Thanks, but in def ready to get my gpw up over 1 per tho. If my damn state would just get legal, then i could concentrate on growing instead of making sure i dont snub my toe...
Just keep plugging away buddy you'll get it.... Not sure how long you've been at it but I went a good few years without even breaking 1per KW. I'd say one of the most important things is your veg/early flower canopy preparation.
So let's say your 1k bulb does a 5x5 square ,which is 25sqft ,to get 2 per light, that's 900gr so divide 900by 25= 36g a sqft or a little under 1.5oz. So whether you have one plant per light or 30 you've got to have the tops and branches to produce that zip n half per sqft under every light everywhere consistently with little to no light hitting the floor. In your pics you've got some good sized buds it would appear those buds are no smaller than the buds in my room when I hit 3 but I'd bet your room wasn't a solid canopy of buds that size. I use plastic trellis that's got 6" squares so that's four squares per sq ft I aim to have one killer top per 6" square with maybe a few secondaries, depending on strain. Knowing your strain and mono cropping makes it a lot easier to have that solid level canopy.
Of course having a dialed room is key but if that room isn't full to capacity then you're not gonna hit good numbers regardless. Nutes are important but as long as the plants needs are met brands don't too much matter. So knowing how much they need before you get any kind of tip burn is very important as over feeding will actually hold them back.
Another thing that makes a massive difference I feel is temperature control. So in veg and early bud (first 3-5w, strain dependent ) keeping it warm 80-85f (measured at plant tops) 70-75% humidity day and night equal with about 1100ppm co2 (day time)will top out the plants metabolism and help you build that structure you need to fill those squares. Once they're done growing in height I do a heavy prune leaving only 12-18" and if the canopy is still too tight I'll do a deleafing a week later. So usually I'll prune heavy at 3 weeks and a selective deleaf at 4. Note if your canopy is tight by 2 weeks in a selective deleafing then can help reduce stretch too. I also start dropping the temps and humidity bout 4-5 weeks in maybe a couple degrees a week so by week 7-8 it's about 75ish at plant tops. Sometimes I'll do a lil deleaf again around 6-7 weeks too to help fatten up any lowers. The last couple weeks I drop to about 72f with night temps around 65.
You gotta work your ladies to make em put out don't leave them to their own devices they'll grow all lazy and unproductive. A good book I read many years ago Secrets of High Yield Gardening by graham reinders is a good read if you're interested. :) Good luck bro
