I really didn’t do much other than keep light close without burning. Was there anything else that I did (knowing or unknowingly) that created these results? I know i didn’t want them stretching for the light.
It looks like you’re using cfl bulbs which is fine for seedling’s since you can keep the bulbs within inches of the seedlings without the heat burning them up. It looks like you might be using a softer light like 2700k(warm white) if so it would be good to switch to 5000k(cool white) or run a mixture of both as while vegging plants prefer the higher kelvin lights. In bloom the warm whites are prefered.
I’m no pro either, only have 6 or so grows, but I have learned a little about light spectrums and have used CFL’s before for seedlings. You can literally get away with having the light just a few inches away as long as the grow environment is kept cool with light air circulation with a little fan and exhaust in the grow box or what ever.
You can get the CFL’s in all wattages like the standard 23watt(equal to 100 incandescent) or higher But the 5000k is just the cool white bulbs and the 2700k is the warm white bulbs. LED’s will be better as long as it is a decent light with enough wattage. But the CFL’s can still help with supplemental light for sure.
