I just realized I didn't give any specifics on the grow, lol.
It's a 5x5 flower room with a 3x3 flood table, 37gal reservoir (tote), a single 600 in a sealed reflector, 6" - 450CFM fan and a carbon filter (Can 66, I think). I'm using GH Nutes with some FF soluble supplements added in flower.
I sprouted the seeds under a T8 fixture using a heat mat, dome and plain water. They'll stay under this MH conversion bulb until the light cycle is 12/12 and then I'll switch to the HPS.
