DWC gph per bucket

  1. For a dwc system how much gph air pump do i need per 5 gallon bucket?
     
  2. ...? bump?
     
  3. alrighty, first off it really depends on your setup, and how big of plants your goingto end with when you flower. if its a small 2-3ft plant around .8-1 gph is good but the more the better when it comes to oxygen to the roots with dwc!
    around 1- 1.5 gph is best that ive found for really agressive growing
     
    • Agree Agree x 1
  4. what for real its that low??? cause I just got 2 65 gph air pumps with duel outlets. I was gonna use the 2 to run 4 buckets but now i think i can run a hell of a lot more.

    Unless I am not useing gph but something ells but im prety sure it is rated as gph
     
  5. I just use 30 gph and it seems like its more than enough.
     
  6. 30 gph per 5 gal bucket?
     
  7. do thoughs small bubble wands suffice? Thats what i got 1 for each bucket.
     
  8. Since I use 2 airstones per each 5 gallon bucket, I like to first double the 5 gallon bucket to 10, then double that for each airstone which is 20. I couldn't find 20 gph air pumps so I just used a 30. Yes it doesn't make that much sense but I was high when I came up with it and I just stick with it.
     
  9. A bit of advice, use dual outlet airpump and a minimum of 2 stones per bucket, share 1 airpump between 2 buckets, this way you have a back-up in case 1 of the pumps fails.

    I currently run 3 dual airpumps in a 18 gal sytem(it only has about 10 gal of nutes in there and my plants love me for it.

    More air = more and bigger root system = bigger bushier plant = bigger yield.
     
  10. ok so i need touse 2 air stones in my 5 gal so then to do this i can put a splitter on each of the outlet rite and use htat to make 2 stones because its a 65 gal air pump so that would make 15 of it go into each stone. as I wanted each 65 gal pump to support 2 buckets.

    I noticed that O2 pumps made for hydro are mostly rated in GPH (gallon per hour) but I've seen quite a few O2 pumps from wally world or petco that measure output in LPM (liter per minute.) Its easy to overlook the suffix so I always read it carefully.
    I noticed this when I was comparing my Elemental 4 outlet pump to my tetra 2 outlet deep water series (made for applications up to 8' deep if I premember correctly) I looked at the numbers alone first, one was rated for 9 and one was rated for 254.... but that was 9 LITERS per MINUTE and 254 GALLONS per HOUR. so when I did the math and compared them again, it looked more like the way I expected.
    9 LPM is 142 GPH, so my quad port is putting out a little less than twice what my dual port is.
