Honestly, I think it really depends on your genetics and controlling your environment/ dialed nute recipe and spot on pH more so than the nutrients/ setup/ lights you use. don’t get me wrong, that stuff is important but I know guys hitting 3lbs per light with old single ended hps lights. I have a 4 light room(
gavita DEs) In ebb n flo buckets and 39 plants(odd shaped room) and I produce some pretty quality sticky buds Which is very small scale, usually hitting about 2.5lbs per light . On the flip side, my friend is a big grower and she’s running about 30 rooms from 6 lights, 12, 20, 30 lights etc and she grows very high quality buds and usually does 2.5-3lbs per light. I’ve seen her even hit as high as 4lbs per light which is insane to me as I’m still trying to hit the 3lb/light mark. As for organic, I’ve ran a soil mix and used
nectar of the gods line and it produced some very very tasty buds but the yields were just not there but my experience is limited with “organic growing”. I maybe did like 1-1.5lbs/light and it was very difficult and time consuming and tons of different bottles. I run hydro now with a pretty simple recipe and still grow very nice buds with no problems. I still like to use
notg Herculean harvest liquid bone meal(rock phosphate) to flush with in hydro and I get spectacular results and it really helps the flavor. at the end of the day weather your running organic or synthetic it all has to be broken down to ionic form which the plants can absorb. Hydro/synthetic is just way faster because it’s available for the plants right now where as organic depends on microbes and benes breaking down the nutrients in your soil to make them available to your plants.
If you’re considering LEDs, check out phlizon LEDs. Their copies of the
gavita 1700s and about 1/3 of the price(about $500) same led diodes and drivers. I’m setting up a big room right now with 16 of those and so far I really like them. I’d say do the 640 watt phlizon and do a 4’x4’ if you have the space Those style led lights can do 4.5’x4.5’ foot print roughly. You’ll need a decent little dehumidifier like 30-50 pint and a little r2d2 style ac unit if you wanna do it right
here’s some pics of my current grow that’s week 8 today and almost ready to flush.
