Amount of CFL vs Higher Wattage.

I think I'm actually going with a 400w CFL, even though I've always been nervous about the energy bill/ballast setup and shit. For my mother plants I'm going to make a CFL cab though.

You gotta realize that HPS has the best efficiency. For 400W youâ??ll get about 50 000 lumens. VS a 400W CFL Iâ??m guessing would be like 24000 Lumens.

So if you only want that much light go with a 250W hps save on the bill.
