Use both if your grow environment can handle the extra heat. Basically there may be some stretch or less stretch from adding or not adding the extra MH during Flower.
frostedwonder Reviewed by frostedwonder on . Can I use my MH during Veg and Flowering? So I already got a 150w MH pendant and was wondering. Can I use it for both vegging and flowering? Just wait till the plants are about the height I want then switch to the 12/12. I know this probably won't yield like the pro's but I just can't afford a two different light setups. Thanks guys! :hippy: Rating: 5
