Bloom not working,need advice

Im running 2 mars hydro 2 400 and when i flip the switch for bloom on one of them. The lights wont come on,just the fan. It works fine when the grow is switched on.
I’ve contacted mars hydro,just waiting on a response from them. Im on week 5 of veg with blue dream autos right now.

Have you tried giving the problem light a good smack? Sometimes that gets stuff working. Good luck with Mars customer support, let us know how it works out for you.

Unplug and remove case cover, check that wire on switch isn’t broken or switch isn’t bad. If not one of those, driver for that portion may have failed or there is ground condition.

I think this was asked before for someone. I remember there was what he/she called a hidden second switch on opposite side of light.

Thanks,I’ve been lingering around for some time now. I needed to get this light sorted before flowing so I figured there’s no better time to join like they are now.:joy::joy::joy:

It really doesn’t matter.

The lights aren’t bright enough to use just the bloom switch, both switches should be on after the plant is past seedling stage. This is true of all blurple lamps.

Yeah,thats why i was hoping to get it sorted before flower. I plan on getting a spider farmer SF 2000 soon as i can. Thanks

Can you put them outside?

I might have to put one out. Mars hydro wasn’t no help. I wont be able to get a new light until july.
