Hi all, currently germinating some seeds in rockwool cubes, the first few have sprouted today so I have them in the prop under a maxibright 48w t5 light. The thing is, I have a 3hr blackout gona happen on tuesday in 5 days time for a new meter installing. This is gonna happen right in the middle of my brand new babies light cycle! Question is,will this do much harm? And if so, could I run this light for the short spell, off a battery? If so, how? Thanks in advance guys, any help would be awsome!
