DK everything looks like it's going well. I love the mylar in the cup idea...I will be using that on the next merry go round. From what I can tell you can put the plants closer to the light. You are safe at 2in from the light. I would transplant when the second leafs start coming in, but that's just me. I like to know that the roots have been developed just a bit to withstand the transfer stress. Good looks man!
Sweet thanks for responding and I shall keep them in the cups until the second set of leaves...and question if I transplant the little ones into smart pots with fresh soil will I have to hold off for another 3-6 weeks before nutes start coming into play?
Did you make the light fixture too?
