what kind of g/watt can you expect from cfls

just curious about growing with cfls and i wanted to know if its less per watt using cfl rather than hps and how much less per watt

It depends on how many light you use, but I'll tell you this, HPS is a lot cheaper in the long run if you want to produce a lot of bud. Maybe for now, focus on producing good bud, then work on producing a lot of it.

i have about 200w of flor. on one plant?

that's about 14,000 lumens and should be ok for one plant. you need the right spectrum for the period of growth, however. 6500k for vegging and 2500k for flowering.

I had a 388w CFL grow going with 6 plants. I yielded 5.5 oz in 2 months which I think breaks down to about 0.6 g/kWh. Lower than the 1g/kWh that HPS boasts but it was great bud in record time and yield would have been higher if I had been running more plants with the same power consumption.

.388 * 12 * 30 * 2 = 279 kWh 160/279 = 0.573

im going to be investing in a 400w hps and i will have it in a week could i put 3 plants under it?
