I put a 5000 btu ac unit in the wall...79.95 at hopot

If you have good temps with one light that is great...go to www.TekSupply.com they have a great catalog of fans and all kinds of products to make your home-designed growroom easier on you. If you can see designs in your head, then you will love this site...greenhouse and pvc supplies.
In fact, they sell pvc by the roll and now I can design a total professional looking system to market. Check it out!

If you feel the 1, 400 will work then maybe save the other for a flower light...you have to buy agrosun gold(red enhanced mh)...It will work for flower, until later when you buy an hps...there are always great ballast deals on ebay. I wire all my lights out of raw parts, built to suit my rooms. I veg and clone in the same room, mums too, for now...hope this answers your Q

remember, if you want to clone and grow you are going to need 2-3-4 different rooms/cabinets etc...

later lw
