you should of planted them all in small cups and then when they are big enough transplant them , also the aluminum is not a good way to make reflection as it creates hot spots , and if those are CFL's try puting them as close as you can to the plants (y) goodluck ! if you have any questions just ask
alright (Y) if you have the money try investing in good lighting (MH HPS) or even CFL's are good for a small grow i like em because you can put them really close to the plant without burning them . cheers !
