Alwways liked the smaller systems. Was really impressed with your cfl grow. This time round using a 150cfl as a seed/veg grower. About to switch to the digital balast with the 400wmh. Only because for once I have the kit.
On the backup note....just picked up a comercial grade ups from the skip. Full on duall batterry setup with console port for powerchute. Tech speaking I know have a battery backup for my grow. And it was being thrown away cause it had hit its 3 year limit. Gonna power it up and see how much life it has. Wont be drawing on more tham 600w , which is the same as you average gaming pc these days.
