A little confused about hydro

Discussion in 'Growing Marijuana Indoors' started by glaxxy, Oct 11, 2007.

  1. Roots are always submerged in DWC but with Ebb & Flow, they are only "FED" a few times a day and people have said that if ebb & flow jams up, your plants can drown.

    Why would they "drown" in Ebb & Flow and not DWC?

    Someone please explain...
  2. Because with DWC you use a fish tank air pump and air stones to oxygenate the water. That's why they're often called bubble buckets.

    With ebb & flow if it jams up with water on the roots then your plants can drown in stagnant water.
