lol your funny..

Dont use the 2 liter bottles, as clear plastic will cause fungus to grow from the inside out..
Run to a Home of pot aka Home De pot or Menards etc and buy some plastic pots. Dont trash them and you can keep them around for a long time. they are $1.50- 2.20 each.

best thing tostart with is the 1cup party cups, you can tip them over as you see fit and check the root growth, then move to 1qt-2qt size(standard tomato size when purchased at a store.. then go to a 1-3 gallon size..
heres a few pics of my only baby.. I went el cheapo on my grow.. really cheap. but spent a little when i needed to..

-To be honest with you the group shot, I put those in to big of a home myself.. should of went one size smaller, I was lucky and didnt have a problem
