i just bought a 400 watt light. its a switchable ballast so it will work for hps and mh. BUT!!!!!! there is no switch or anything to switch it to hps. i thought it would be simple and u push a switch up for mh and down for hps. BUT NOTHING IS EVER SIMPLE!!!!!!!!


does anyone know how to switch the ballast?

thanks alot

i have one of these i bought it used , but it works great. it takes a 400w mh and a 360w hps from what i understand u must run a lower watt hps with this type of ballast, the package on the mh bulb shows what converson hps bulb to run and the ballast has a tag as well that show what it uses for specs. amps so on... hope this helps

Wait till they're about 2 weeks old...flouro's will work just fine...infact that's exactly what i use untill they are ready to be flowered, and then i move them to the big 1000W HPS
