Hi fellow growers!
I'm thinking about trying a small aero setup for kicks, but after doing a bunch of research there's still one major question I have - Does the pump run constantly or in bursts? If it operates in bursts, what's the timing?

Thanks!

pump is on a timer, many increments are used. one of the most popular mini increments is 1 on, 4 off. many do 15 on, 45 off, some do an hour on, hour off. don't run continuous, as this makes the pump heat the water, which encourages pythium (root rot).

Thanks! I think I'll try a 1min/5min cycle then. Thanks for the tip about the pump heating the water. Would an external (not submersed) pump be a bit more desireable then?

Thanks again for the advice!

yes and no, it's all preference. on a timer, heat from the pump will never be an issue anyway .

i like submersibles as it doesn't limit my ability to remove the res from the room, where as the pvc connections of a centrifugal mean it's basically a permanent installment...
