Essentially any floro's will do for starters.

Keep the real close to the plant tops. Keep a fan on them to keep them cool.

Your challenge will come once they start growing at about the 3rd week.

At that time, you'll need some serious full spectrum CFL's to continue vegging without stretching.

If you are wanting to grow some serious bud, dont bother with anything at Home Depot for lighting.

They do sell the MH and HPS bulbs but not the ballasts you'll need to run them.

GO figure.

Also, think about your 4 foot height. Your lights and exhaust will take some room, and then the pot you grow your stuff in will take some room as well.

How much does this leave you for height?????

Same mistake I made.....

My space turned out too small to do a veg chamber and separate flower chamber.

Anyhow, once flower time arrives, forget the floros. Unless you get real serious about LST and invest in some real floros. Not cheap.

But, I suppose it could be done.

Yet for the cost, you'd be better off with MH or HPS.
