cool, I just didn't see it. you can get light blocking out curtin's (liners really, but their white who could tell) at bed bath and beyond 20% coupon.
I just soak the for 24 hrs, i use a shot glass. if they sink i put them between damp paper towels, folded and covered. mist when needed. once i see a 1/4 root, i drop them 1/4 down into damp soil, root facing down, in a little plastic pot , cover them with soil, and in a few days i see sprouts, i use T5's for veg and seedlings no problems, led's in bloom helps keep the heat down, am upstairs also. If the seed is good and sinks on soak should germ and grow. I use tap water to lightly water around the seedling as to not drown it or push it further down or on an angle if needed. I damped the soil in the pot first before planting the grem. seed. cuts down on possible drowning.
Not sure if am helping but I grow upstairs use T5's and in oakland county, all is well.
