OK, so per nongreenthumbs advice, I have transplanted the sprouts into the large 6" cubes and placed them in cheap solid trays. I will water them with my nutrient water when needed by dunking the bottom 1/3 in the solution.
I decided to fire up the 400W mh bulb too, so im sure theyre liking that. The bulb is about 2 feet away from them. I still havent received the cooling tube to cover the reflector, but I have a fan on it and the temps near the plants is about 79.2°F. Humidity 49%.
I will take clones from these to fill the flowering box I made with the HydroFlora.
