6500k which are the bright ones work very well for seedlings.
killerweed420 Reviewed by killerweed420 on . What spectrum of floro for seedlings? Hi Everyone- I'm going to put my seedlings under a floro tube until they're big enough to get in the veg tank. Looks like there are plenty of different spectrum tubes for floro and I wasn't sure what to get. Warm, cool, full spectrum? 6500K 5000K? Something else? Remember this is just for the seedling phase but since it's available I'd like to get the right tube. Thanks. Rating: 5
