DWC air pumps

Discussion in 'Growing Marijuana Indoors' started by zombie16, Sep 16, 2009.

  1. i am going to build a DWC wiht an 18 gallon rubbermaid for 2-4 plants and i have an old rena 300 air pump but it seems to not work that good or is it to small i dont know if i should get a tune up kit or just buy a new 50$ pump(or is a 20$ pump good enough for an 18 gallon res.)
     
  2. i think that the better quality pump you get for your res
    will result in better roots, better roots better plants
     
  3. i got a pump off ebay for 30 bucks with four output holes. it PUTS OUT. i had it in a 25 gallon res and the whole thing is all bubbly. works great.
     
  4. ok im going to look on ebay an all that thanks
     
  5. Personaly i would go to you local fish store and look. On the box it will tell you how many gallons it can do and also how many ports.

    You are far better off buying it from ebay, unless you want to pay the high markup from a fish store.

    It's worth it if you need a cheap pump right now, but for the more expensive stuff especially, you can save a lot picking it up online, and you will have a much wider range of options.
