like the title says whats the max growing area for a 600 hps? i wanna flower at least 4 decent sized ladies at a time.. ( start flowering at about 2 & a 1/2 foot) is 600w enough for that?
A 250 watt HID will illuminate a 2' x 2' garden. A 400 watt HID will illuminate a 3' x 3' garden. A 600 watt HID will illuminate a 3.5' x 3.5' garden. A 1000 watt HID will illuminate a 4' x 4' garden.
or just like jimmyspaz says and/or check out the grow faq...good luck!!!
