I read today that you can use a MH bulb with a HPS fixture as long as they are the same wattage any thoughts?:confused:

That Would Be New To Me, My Ballast Are Switchable So No Problem, I Would Consult Store And Manufacture Before, Its One Hell Of A Pop If You Piss Off One Of Those Bulbs, Mine Are 1000w Small Bulbs Not So Bad.
I Got Pics In Gallery, The Thread To Them Is In Grow Journals. Please Read And Check Out The Pics. Let Me Know?? Hope The Info Helps. Post U Later B.

You can buy a MH conversion bulb for hps ballasts. It MUST be the special conversion bulb- google phillips retro white hps.

mh and hps bulbs are not switchable as the hps needs an igniter which mh balast dont have.You can use the same ballast if its a digital or switchable ballast cutom designed for both otherwise you have to use conversion bulbs.

High Gdave.. True, one can not use MH in HPS ballast & visa versa but there are ballasts that will run either mh or hps bulbs. I just bought a 400 w Gallaxy and it will take either bulb and make the switch internally without manual intervention (except to take the one bulb out and put the other in).

(Replced a damned Lumateck that took to flickering and going off and on.. ON ITS' OWN! 5 months old. Sent it back, they "fixed it" and returned it to me.. I don't trust it now. That is another thread somewhere I'll bet):cuss:

On the other hand, I've become very happy with the HPS for the entire grow, veg thru bloom. HPS has more lumens, screw the color. It works great!:clap:

My 2cents

Good luck Dave :joint:

"You can't use a standard hps bulb in a mh fixture, but you can use a mh bulb in a hps fixture of the same wattage. I didn't think this was possible till several years ago when someone I trust told me it was possible. So I decided to try using a 400 watt mh bulb in a 400 watt hps fixture."
