HI, BeFree

Thanks for the advice. I'm using an 150 Watt HQI (6000K I think) with 2 CFLs(not sure the Kevlins though, they were used and mounted on my Sea Fish Tank before) I thought with the 250 watt HPS coming I'd be rid of the CFLs, now the light spectrum question I've run into seems to require an CFL ... LOL .. I wonder what Kelvins of HPS you are using or most people are using.... ? 2100 K or 2000K ?

As for the grow space .. I'm using a metal cage closet ( L 92cm x W 60cm x H 160 cm ) My room is 9 feet x 9 feet with an air conditioiner.

Unfortunately, the only kind of HPS light bulbs I could purchase near my town which all have the color temperature of 2000 K. I then Rating: 5
