im only on my first grow as well but i dont see a problem with bringing it in doors as long as it's not in to flowering it should be ok under cfl's for now but thats my opinion i would honestly wait till some one with more knowledge comes along. were they both out doors to start with or was one in and one out coz if thats the case they would probably have to be kept apart due to insects and disease's that might be on the out door one but again im a newbie at this so its up to you mate. i hope every thing goes ok for you take care and happy tokeing:rasta:
