I have a 2'x3.5' closet space I started some stuff in last yr with a 70 watt hps, and a few 2' t8 plant lights. I'm wanted to upgrade a bit, and last fall I got a great deal on a 2'x2' 8 bulb t5 light with 8 bulbs for veg and 8 for flower. The T5 is capable of running just 4 of the bulbs, or all 8 controlled by 2 switches. Without looking up the stats again this light (according to the bulb wattage) uses 200 watts at the wall. The plan is to start beans and run them for perhaps a month at the outside. The exception is..... I may start some regs and sex them to grow out a mother plant or two to take cuts from before they're set out themselves. I was thinking of buying a spider farmer sf 1000 as an upgrade, as it pulls just 125 watts and the wall from what I remember. The electricity cost leans me towards going for the SF light, but my question is besides being more efficient .... is the SF light worlds better than this 8 bulb T5?
