What is CFL?

Is it ok to use shop lights? They are like 4ft long floros that come in 2 per unit.

What is CFL?

cfls are the kind of floro that screws into any standard light socket. You can buy them anywhere, well maybe not anywhere, safeway even has em. those are the ones to save energy in you household lights.

they can also be the 4' tubes you buy at wal-mart. they don't exactly "screw" into a socket but they are easy to find and use.

not so great for flowering.

It's a cheap way to grow. It's the way I'm currently growing.
