So since my last endeavor trying to find a pump to run 4-4x8s with 16 site (2 octa bubblers) now on 4 zones to help with the pressure. I pretty much was stumbling around and saw jackmayoffer I think his name is on thcfarm and saw he ran. a 3/4 grondof. Would a 1 hp submersible pump work? I beilive I was told. Is there any other brand of pumps that arnt as pricey anyone's rocking that are happy with? Thanks !

Bump for some help. Would a 2500 gph be over kill for 32 sites with 2-1/4" lines going to each site. I plan on plumbing it with 1" pvc, then to 1"-1/2"-1" Tees. Will only a mag style pump work? I see submersible pumps that are 2500 gph with a 10' head. There about half the price and I do need 2. I definitely don't mind spending the extra for the mag just wondering if anyone's used anything other then the mags. Thanks!

sorry can't help you with air pump dimensions. been over 20 years since i used a hydrofarm type set up deal. worst case email the pump suppliers. i know the info is on ic some where, just hard to find the exact thread it be in.

if you want to keep things simple, just forget the whole air pumps and go for coco with drip irrigation lines. it's so simple and works so well, i'd never fuck with aeroponics/hydro growing again. even the taste is better with coco and it grows just as fast as a full hydro set up.

How much are you willing to spend on pumps? I learned a long time ago that those HP ratings are all rubbish. What you need for bubblers is a pump that can pump at higher PSI because the pressure drops quickly with each additional head. I would get a mag pump at the minimum but a permanently plumbed external pump is best.

you want a diaphragm pump.

there is simply no reasonably priced centrifugal pumps able to develop the pressure you want at the very very low flow rates that you need.

[Dr. J]

Hey guys so is the diaphragm pump the ones that are plumbed in? Do you know how big of a pump I would need?

[Speed of green]

you need to know the gph of your emitters and add them all up, then size your pump to that.

like this

32 emitters @ 1 gph = 32 GPH, divided by 60 gets you .53 GPM.

you will also need a 12v power supply and 12v solenoid and a 12v timer. if you assemble everything and the pump is short cycling you will need to add an accumulator tank.

all in all youre probably looking at $100-150 for everything with the accumulator tank & plumbing throughout the room.
