I put a 400w MH bulb in a 1000w system? my 1000w ballast says MH/HPS so im guessing its switchable. but i only have a 1000w HPS bulb, and a 400w MH. if i put the MH in will the excess power cause the bulb to break, blow, burn out, etc?
yah thats what i figured, anyone ever try doing something like this? lol i would try it out in the back yard but i dont want to risk my whole system to test a theory lol
Now that's a good idea. It's too much arch for the bulb to handle and it will burn the bulb out really fast, it may work for a short time. http://forum.grasscity.com/grow-room-design-setup/287010-can-i-use-400w-bulb-1000w-ballast.html good luck -J
