Pump up the jams?

Hey all, noob question here… can I turn up the watts on my 600w mh/hps Vivosun lamp with digital ballast? It’s on 250 with the mh bulb in now and I want to turn it up. Can I do it while it’s on or does it have to be off? My dark period is when I’m not home… would you go to 400 or 600? Thanks, Pin

Found the answer. You can turn them up or down while on but need to give a few minutes between settings for the ballast to adjust. I also found out that a HID light when being run at less than it’s expected wattage may be throwing a different light spectrum than intended


Yeah I’m an led guy for obvious reasons

Maybe not so much with MH but HPS I think is more sensitive to that. Turning up the light is kind of based on how much canopy coverage you have and height above it.
