When I first started this grow I had no lights to use. So I did what anyone would do...went down to the basement and ripped out the 4 foot shop light flouros and mounted them above the "fish tank". When my friend saw my sorry ass set up he donated a 400w MH to the cause. Whoopee! So, with more lights, I felt at ease to germanate the rest of my good seeds and I made another tray.
