    #337284 - 12/27/09 11:07 PM (6 years, 11 months ago)

Im working on an aero table.  How can i calculate how many GPH i will need for my set up.  Also, should i use 1/2 or 3/4 PVC?

I don't think you need to calculate GPH - my advice would be to go with just any conventional miniature water pump that people use for their hydro systems - they should be fine. Could also go with a flood pump and shave the impeller, depending on the size of the system,

PVC size should correspond to your pump nozzle size. 3/4 OD Is quite big. What's the tubing for though? Don't aeros use those little tiny hoses with the sprays?

lol.  I would need to know a ballpark GPH to maintain my 25PSI requirement.

The tubing is for the aero system; the'res more then one way to skin a cat; i want hardline not soft...

What kind of tips/sprayers will you be using and how many?

You need to find out the GPH of the tips, and to be safe add about 25-50 GPH when choosing the pump.

I have a 395 GPH pump pushing 18 ezcloner tips, and I used 3/4 PVC for the pumping.

Word.  its looking like imma use 20 sprayers (20-25gph; adjustable), and was planning on 1/2in pvc just cause i dont have the most room in my area to work with.  Only thing that sucks is i'll prolly have to order the pump.  We only carry the 340gph model; imma prolly pick up a 450-500gph then and should be fine... worse case; i can pick up the adjustable sprayers; prolly will just to be sure i get the height i need to spray the roots in the first few weeks...

Thanks.  I didnt know if i should actually add up the GPH and thats how i get it or wtf.

Last Q:  Howed you go from the pump to pvc?  Im trying to gather ideas cause the pump i was looking at had like a 1/8 outlet...
