I think its common knowledge but incase someone doesnt know...

Are you prepared for a power outage?

You should be because if you dont your lights will go out and your plants will eat shit sandwiches. Well maybe not but keep the ladies in mind. Grab yourself a UPS. They have 2 hour and 4 hour batteries that i've seen. It will run a computer for those specified ammounts of time. Lights dont take up that much at least not mine.

Hey this helps me alot ive been looking for somthing like this-- good post

Thank you. The brand APC is a good one for this. Small and versitile units.

Well I have one for my computer but it won't be big enough for my grow.

It doesnt have to. You can also choose to only hook it up to a few lights as emergency backup. It'll be like a cloud system rolled in or something the plants wont be too worse for wear.
