Well, hydro is certainly going to require more from you in the form of care and maint. Also, rez temps are usually an issue in most grows. You can go the expensive route with a rez chiller which will acurately maintain temps or go the cheap way and thow a frozen jug of water in the rez. Im am experimenting with the frozen jug myself. Hydro can have huge benifits over dirt as far as growth, yeild and quality but it is also much easier to screw up and kill your plants. Do some research first and get a good handle on some of the basics. It will save you time and money.
