Less light for an auto? Maybe 12/12?
Been going with 18/6 for my cream autoflower from growers choice from Day 1. Now 5 weeks into flower I’m wondering if she would benefit from less light, like 12/12, as you would for a photo period plant. What do you think? Would she be happy flowering in some more dark period?

LED Kelvin Temp 3000k-6500k
Is there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

Anyone used the Phlizon Cree COB 2000w lights? I’m running two in a 8’x4’ under a scrog net. 5 weeks into veg but nowhere near where they should be. Used only the COBs in veg as some suggested but had to put on full blast today and hope for some speedy growth before I flower them

2x2x4 yield expectations?
I want to use a 2x2x4 tent, growing (Gorilla Cookies) autos in Nature Living super soil mixed with Coco Loco. I want to yield just a few high quality ounces. Is this easily achievable with one 3 gallon pot under a SF-1000? Should I be concerned with any plant height issues?
