MH systems
 

im sure this has been talk about already. But im going to ask anyway.
Is there a difference in the MH system you get from a hydroponics store and the one you can buy at J&L or OA.?
I know its cheaper looking and the bulb I would have to get somewere else but the cost is so different.

Have you ever been in OA? Go look what they are using on all their tanks. It looks like its all MH from a hydroponics store.

I just want to make sure. The last thing I need is my house burning down. LOL

Also ensure suitable ballast.

ok I understand now. I will be getting a m80 soon.

Thanks everyone..

ive been using a 1000 watt hydroponics halide i picked up from a friend in BC over my 90G for 2 years now

Magnetic ballasts push out more PAR than the fancy and more expensive electronic ones too.

But how many lights do you have on your 90? and what watt

sounds like 1 1000w bulb to me.
