These guys are giving you great advice, take it. Look into drip and bubblers or DWC (Deep Water Culture). If you grow big you will have some sting lines holding plants up. If you go 1000 watt get a hortilux or sunmaster bulb, you won't regret it. Do your home work and let these guys help you tune it in. Veg under fluro's it's cheap and just as good. Either 18 light 6 dark or 24/7. 12 hours light and dark to flower. Hydro is the bomb when you get it tuned in Good luck and welcome to the wet side. LOL
