give it a try cuz. You never know until you do it yourself..People will tell you whats best, but it all comes down to doing it yourself. I've been reading and growing on cannibis for over 12 years and have never seen anyone do it, nor have I dont it myself. Please do it and post your results for everyone here to see! Now, as far as having more potent buds with MH is a little crazy to me.. If you want to get the conversion bulb with both mh and hps in 1 bulb, it would be best. The bulb has both blue and red which is what you want. The more UV light, the better THC production. I know a lot of old time growers here on the E.Coast, and they strictly use MH. I've also had the same people tell me my stuff is just as good using hps bulbs.. But again, it all comes down to personal experience..
