help does it matter on the light when u are flowering

im about to flower my plants but im useing an 1000wmh veg can i keep this light to flower or should i hps it i have both diffrent bulbs

use the hps bulb if you have, the different light spectrum will give better results

right, you could use the MH but buds would be better if you switched to the HPS for flowering. Many people just use either light the whole way through with fine results. maybe not the best possible but just fine.

fasho good looks
