hmm. Im not pro here, but ill venture an answer.

Transplanting might stunt growth. But not too much In my opinion. Look at the link below in my signature. Two of the largest ones on the left were left in a TINY pot way too long. then transplanted. so by therory that would stunt the heck out of em. but they are Huge.

Can u bring them inside. YES

Yes you can do hydroponics. but IMO thats alot of work for just one plant and ur first grow. Id go with some Good soil. All i can recommend is Fox farms ocean forest soil. Its all ive used on my first and only grow so far.

Hmm attention. Id let the plant grow. then take clones. then keep that one female as a mother. That will work if u have two lights. One 2 HIDs or 1 HID and some CFLs. basicaly u would need two seperate spaces. one for mother and plants in veg and another for ur flowering things :}

also seeing as ur boyfriend grows, kinda. You can just get more from him or have him do the cloning stuff for u. then all u need is one light, one space.

But I would say do something. Because one plant is better than no plants. you will learn alot. I know I have.

p.s. Read the FAQS on the forums. they give LOADS of info. But we will be happy to help.
