sorry didnt look.....but you can get way closer just make sure they arent touching the plant you knowyep definitely depends on the type of light....
if cfls....a few inches
if hps/mh....a few feet then bring it in until your plant tell you that is just right
I don't think it matters if those first 2 round leafs turn yellow and fall off, but if your main leafs turn yellow, u would usually have a heats issue or that you dont have enough (N) part of your N,P,K nutrient.thanks.. but my first 2 leaves are turns yellow, yu can see in my last attachments, why this happens? don't you know
I think they might be right, it might cause heat issues. But mainly it looks terrible and un-neat. then again its your grow, you can do as you pleaseGet ride of that tin foil get some fat white paint
tin foil makes hot spots
