how much more do you get from a 600w HID or HPS
A shit loadmore...

I think a 600W HPS is like 113,000 with a reflector...

I think....

Somewhere I got a chart that shows the increases.

I didnt think C02 was limited to lumens...I thought color spectrum was as important....

Older floros didn't have the full spectrum like they do now...

Seems if you have enuff CFL and lumens, and light spectrum the Co2 should be functional...

Where am I off here???

Lead me to stoner paradise and I will follow..
