iblodro4220 Reviewed by iblodro4220 on . One HPS One MH Bulb for last five days of Vegging? About to transplant into 3 gallon pots, don't have two MH bulbs, going to just throw the HPS in the other lamp so I can cover the forty five babies will light. I know people have vegged exclusively with HPS at times, but am I going to confuse the babies with one of each in the room? I highly doubt it's a problem but just making sure.
