Yesterday was 5 weeks of Veg for my plants. When i was setting up the light timer i realized that my ballast isn't for HPS! I already own the bulb and dont have any more money to buy a ballast. Are things gonna go ok using my MH?
it would work but u wont get the most out of ur plant. just from the blue and green spectrum. i would a least get a couple of 2700 clfs to at least get the red and yellows to get in there. or get a 1000w hps conv. bulb. or they do make hybrid bulbs. which has both mh and hps in the same bulb. but i think that was pricey. so some nice size clfs would work. or a cheap 150w hps would add too. ebay has some nice ones. check out htg supply. they are really good. good luck
With a MH bulb during the flowering stage you will only produce a dence, short plant with air filled buds. I would either buy a MH to HPS conversion bulb or buy a second balast with 250W HPS bulb and keep both running through out. You need to provide your plant with the correct spectrum of light to make the most out of flowering, or it could be all a waste of time/money.
Yeah, that's going to hurt your production. Either a HPS conversion bulb (to work off a MH ballast, these can be hard to find) or just invest in a new digital ballast that can run either. I don't advise relying on CFLs for your flowering, you would have to invest in fixtures and wiring and such on top of the bulbs, and by the time you spent that you could have gotten the HPS conversion bulb.
I dont know if they make 1000W ceramic MH but if they do I would assume it would work with your setup. Additionally ceramic MH puts out the best and fullest spectrum of light of any HID check it out
You'll be fine. How many plants are you growing? A 1000w of MH is quite a bit and I'm sure you'll still come out with a nice yield. I know people who use HPS all the way through just like I know people who have used MH all the way through. Personally I mix the two except in veg I use only MH. Anyway, like I said you'll be fine and don't worry you'll still have nice buds with that kind of wattage.
Hey i use 1000mh all the way through and i dont have any probs, i have a good yeild, although the flowers are a liitle longer and spread apart. but like i said i get a good yeild and i happy with the product. so dont worry to much it takes alot to ruin your babies. just make sure to water and love them they will be fine.
