I dont wanna make a post about something that has been talked about like hps vs cfl. So... i searched and searched and cant find anything really about cmh. i just want to have a basic understanding of the ceramic MH bulbs. I have read that u cant use them on a digital balast, they are great for veg, and not too good for flowering. i am buying good lights soon and im thinking 250W hps but i dont know about the cmh's thanks in advance for the help.
