I have a sprout thats about 4in. tall under 2 flor which puts out 2550 lumes. I dont use germin., just straight to the "dirt". I chose not to gerninate because I usually damage the "first root". The first time I germinated successfully the plants were terrible, but I used it for filler in my joints and blunts. After that I just started going to "dirt". I can get a plant/s growing within 2 weeks and healthy. List of products and steps to follow. Always remember D.E.A.D. (Do Enough And Die) in a GANJA way.
