The one plant has three cotyledons, which i've never seen before. Hence the dumb joke. It's actually just a lowryder 2 though.

The bigger plants have more than a gallon of soil each, in a 36" long window box planter. I figured by planting them that way, their roots could overlap and thus grow more. Each of the bigger plants has about 8" of dirt underneath it. The little ones are just in plastic cups, but I'll transplant them to 8" pots as soon as they outgrow their cups. No way I could fit them all under the light if they were all in 8" pots though.
