I think it bubbles the water up the tube, at least that is what it looks and sounds like. The air pump is Y-ed in at the bottom to the water tube that goes to the ring under the water level.

What I have done is run both the drip and the air stones. The pump that comes with it is pretty strong is should be good to run 8 drips. Right now I use it to just run 2 buckets with drip and each with a stone. The roots are huge and almost filled half my buckets once I got to flower after only 5 weeks of veg after planting clones. I am considering going to larger buckets as my roots seem to have filled the bucketes now, I plan on using the drip ring becuase my system seems to be working pretty good though I have yet to harvest. Flowering stage is looking good now.

First pic is after 5 week flower and adding air stones for only 3 weeks of that time.

Last two pics are from last week which is about 45 days flower. They are a little short but they started in a cabinet and were removed to a closet when I switched the cycle.
fosomker Reviewed by fosomker on . Few Question regarding DWC grow? Hello everyone, i'm trying out my first hydro grow in a DIY DWC system. i have two different systems and question for both. 1. the first set up is using 5 gallon bucket, airpot, hydrotons, and an air pump to oxygenate the reservoir. just so i understand this correctly...i don't have any type of drip system so do i need to make sure that the bottom of the airpot is sitting in water so the wick can take nutrients to the new seedling? if so will the roots not grow into the cotton wick? and Rating: 5
