no but i would suggest getting a conversion bulb cause from what ive heard the buds are like so twindly and thin cause of the blue spectrum man, i dont know ive never seen it though, either way goodluck man
Heres from a 1000w MH.. works great.. just dont burn yours with bloom nutes like i did.. my baby is still kickin great,even after the burn...it was 1 week now,the plant has recovered...ive smoked from it..OH WOW its so stoney ,lala land... super smooth..
i flowered with a MH once. I have two trays and one of my HPS ballists went out in the first week. The two trays were completly different. I got about half off the tray flowered with the MH vs the tray with the HPS.
his are all under MH. look for "NORTHERN FARMER HP STADIUM GROW". Try searching "stadium". im also looking at the new "Hortilux- Blue" daylight metal halide bulb. its supposed to have a wider, brighter spectrum than any other bulb with all the colors of the rainbow.lol
