Hey guys! This is my first grow! I am posting this a little late as its day 27 for my feminzied auto white widow from ministry of cannabis, I plan on doing regular updates. I currently am growing in a 36×36×32 grow box i built, I currently have her under 4 cfl lights(3 6500k, 1 2700k) my temps...

What do you guys find most effective overall and why? I'd like to do some side by side grows with different mediums (I am, Im just not at the point I could do a very controlled experiment)
