Congrats on the lights! What are your thoughts on running higher ambient temps with LED? The idea is that LED rooms need to run warmer because LED doesn't put out much IR light. Warmer temps also need higher rh to keep vpd in range. Should mean a lot less electric costs for lighting and AC. Check this article. It talks about CO2 and lighting but scroll down to see the section about raising rooms temps with LEDs.
Pretty close IME. 30w/sq ft works for COB and QB type LEDs. For example, the HLG 550 is 480w and will flower a 4x4. A bunch of those QB type boards are 240, 280 and 480w. Lines up pretty good for 4x2, 3x3 and 4x4. 35w will work for some strains but it's good to have a dimmer to bring it down when needed.
My main goal for growing has always been for pain relief (although I rely on weed to sleep too). Smoking Nirvana Blackjack seems to help and most indica leaning hybrids seem to help. Better yet is dried ice kief. The best pain relief we have gotten is from canna coconut oil made from OG Kush and Blackjack. Rub the oil right on you boo boos, it's amazing for certain nerve pain that my GF has. We also use the canna salve made with the same canna coconut oil, shea butter,beeswax and a little peppermint oil.
Sounds good, give it a try. The only other advice about how much to feed is grab a ppm / ec meter tester. Mix a 1/2 strength sample and check ppm. You'll get different opinions on ppm, but somewhere around 600-1200 should work in veg.
Wow, so 16, one cola plants in a 4x4 SOG may produce 1-1.5 LB but you're breaking the law. Or, run 4 tents with one plant in each tent in a scrog, probably yield 4-6 LBs in total but you're legal. I'll take option 2 please!
