How long can I flower with a Mh without too much of a problem. I use a 1000 watt hps that just burned out. I dont have an old one to use, but do have a mh conversion bulb. I put that in, but am trying to see if i could order online for a new one a wait a week or so to get it or if I should drive 2 hrs to the closest hydro shop and buy one for twice the price. The plant are currently in different stages in that room with the oldest only having 2 weeks to cut. Thanks for any help!!!!

i would think it might help with the uv it mh gives

People have flowered with mh it will be fine just kep t on the 12 hr light sch. and its going to be all good just put the hps light i when you get and enjoy the bud

I flower by using HPS for 6 days a week and MH for one day a week so I think you will be OK.

I know people flower with mh but I want thick dense buds and you need hps for that. My main concern is that alot of the plants only have 2 weeks left and If i order a bulb today I should have it within a week(should) so one of the last two weeks of flower would be with a mh not hps. I think i am just going to make the trip.
