i have a 400 watt mh light...i'm broke and can't afford the hps conversion bulb at the moment...what would be the effects of flowering with the mh bulb..would the yield be much lower...thanks
Yes you can still use the 400 watt metal halide to flower though youl notice considerable difference in the bud it self yeild will still be better then floros, the best bet though as you stated you can afford a conversion bulb would be to possibly add a few red spectrum floros in the room with the MH to help change the spectrum a bit to make it more viable to flower your plants, I really to hope this helps you out, if you have further questions or need other help just ask!! Peace and happy growing OntarioBud
