well first off like previous poster said, get rid of the tin foil, all of what he said is true. and if you realy serious about this being your new hobby i suggest you figure out a "sealed" place for them to be in. this will alow you to keep humidity and temps constant once dialed in properly. and if you cant aford a ready made grow tent, you can always build one for real cheap to whatever size works for you(i know, my grow room cost me less than $50 to build and its dimensions are 5'WX4'DX7.5'T, and that included everything, framing, plastic, mylar, and ventalation) and it will be just as efficient as any "high dollar" grow tent.

theres no way of ever knowing what species you have, there is way to many out there. all you can do is enjoy them when they are done:jointsmile:. good luck with your grow my friend!!!:thumbsup:
