QB 260 dimming question

  1. List item

Sorry Question was what power should my dimmer be on during early vegetative growth? Also was wondering if someone could offer any heights? I’m growing autos in a 3X3 tent 5 gallon fabric pots & an airpot.

Your height will be good somewhere between 24 and 36 in. Just watch for stretch, if it starts just lower your light a little until stretch stops. And you can run 60 to 75 percent on the dimmer. They dont need nearly as much light as in flower

Thanks Sirsmokes. The site recommended for a 3X3 but I see a lot with higher watts in same sized tents. Usually multiple smaller boards though. I was thinking about adding my pink COB for more watts 210 wall watts.

With quantum boards you can shoot for 30 -35 watts per sq ft. So a 3x3 you will be ok with slightly less than 300w. Im not familiar with the max watt draw of the 260.

I’ve been told 285 but I have no way to measure.

That’s the only drawback to the QBs. I bought a Kill a Watt meter to measure the draw. That dimmer screw is super sensitive! I ran my 260s at about 150w throughout veg and have gradually increased the wattage after flip. Mine should be at 250w in a couple days.

So don’t go full 260/285 watts until 12/12 flip. See I think that’s where I messed up before. Thanks
