mh light to hps????

i have a 400wat metal halid and want to knw if i can put a 400w hps?What would happen if i put it on?will it work?

no it wont work,you can get a coversion bulb however

so conversion bulb would be best or just get a seperate hps

Get a digital ballast that supports both. That's what I have. When it comes time to flower, I just switch the bulb.

well i would like to but wanna go the cheap way i guess u can say

what would happen if i put the hps bulb in my mh light?

Something like this-http://cgi.ebay.com/Eye-Hortilux-360-watt-HPS-Conversion-Bulb-400w-MH-lamp-/350381099359?pt=LH_DefaultDomain_0&hash=item519457495f

it wont light.. .thats what will happen, lol

Don't do that you will pop your bulb or it will quit working or you will fuck up your ballast there is a reason they rate specific bulbs and ballast for your safety.

thanks i wanted to hook it up but was worried it fry my ballast

Yeah it certainly will not work if you put the HPS in the MH or vice versa. You can buy a switchable ballast for pretty cheap. All I do is switch my bulbs and I am good to go.
