Yeah I have the root thing all figured out. There is a styro foam separator in each pot. They come in two pieces. You just hook them together cut them down and put them in. Fill with soil and let grow. When you are ready to transplant you just yank the separator out and you have 4 cubes 1 each with a plant and it's own root system. It's pretty cool. I use them so I only have to use a couple pots for germination/seedling stage.
As far as the light goes I use a basic 40 watt 3 foot dual plant/aquarium light you can pretty much buy anywhere. It's kinda low tech but I've had some pretty good plants in the past. Just these were shooting up so fast it kinda freaked me out. And yes the light was a little far away from the top of the plants. I think this will fix my problem. Thanks guys.
