It sounds to me like your best bet is to grab a tray light Or some fluros somwhere and try and set up an inexpensive smaller room.

If you start those seeds under the HPS they are gonna stretch plus not reach their potential.

just my 2 cents. Im not to experienced but I do know that seeds under HPS espically at 12/12 is far from ideal and I would think it will take so long for those seedling to get strong.

I'm sure what you want to do is totaly possible I just don't think its gonna be worth the hassle.

lets see what some other katzz say...:jointsmile:
