the manufacturer's sticker on the ballast says "400 or 430 watts" ...dude at a hydro store told me it takes both when he sold it to me. i've been running a 400w hps since last november with no problems but i am changing my setup a bit and want to run the 430 bulb for the extra daylight spectrum so i can do both veg and flower stages ....
when i went to go buy a son agro 430w bulb at another local hydro store this week they asked if it was for a 400w ballast or a 430w ballast. i told them it was a combo ballast (lol ..) they said no such thing and if i ran a 430 bulb in there i would not benefit from the increased blue spectrum... i am confused why a ballast would state 400 or 430 if there is no point in putting a 430 bulb in my ballast. all opinions gratefully appreciated in advance.
