High!
Not sure of what you mean... but about the light bro, they got 2 MS006 x 1 module on for the first 3 days then 2 modules on till now at 60 cm height.
They are growing at different pace because they came up at different timings...if it is what you mean?
As for the green, it is only the light bleed from 2 X T5's 35 w, so no moss

as for the gnats they are under control so far (Mosquitoes dunk in soil) and in tank / water
+ the stickers to catch the ones that come with the soil...
Peace!
