ganjhound Reviewed by ganjhound on . Can i use a red spec cfl bulb for vegatative growth? Hey all just about to buy myself a £40 red spec bulb for a cfl stealth grow and i dont really feel like spending another £40 on a blue spec bulb, so i was wondering if i use red spec all through the growth of an autoflowering plant would that affect the plant? If so how much and in what way? Many thanks in advance Rating: 5
