In this video we will explain the concept of a Depth Regulator and how it functions, A lot of questions were asked regarding it in our RDWC build and we hope this video helps clarify everything.
A basic Depth Regulator regulates the height/level of water in the grow table
and according to how high or low the inner stand pipe is that will intern define the water level in the table, The inner stand pipe is the actual drain of the table.

Check our Hydroponic RDWC system for the full build.

    Thanks for your Great video, I have some question, Do you use normal water or you have mix the water with other solid? I have seen your small blue pipe what is this for?

    Sir, can i ask one more question? You said that you can use one pump in one table and two lines for water supply right? How about the suction side sir? Can you explain the right way? Thank you…

    I am very interested in the device to adjust the water level
    You can share how and the size (tube size) of the adjustment device
    Thank you

    Thanks a lot for the great video. I have two questions. Do you add the oxygen via the air compressor into the table or into the barrel in the ground? Does the circulation take place permanently or in intervals?

    Hi, thank you for the great videos. I have a bunch of questions but will only ask a couple. I think I saw somewhere that your operation is in Gauteng, South Africa. I have a small hydroponics operation in Mozambique. I have 2.5K greens in Kratky bins as well as fruiting plants in dutch buckets. I am considering moving my operation to the Western Cape. I am using Kratky because of energy constraints. I am strongly considering moving to DWC.

    Can you tell us a little bit about aeration of the water. Do you have any form of air being pumped into the ground tanks or table, or does aeration only occur via the movement of water falling into the ground tank. What is the overall size of an individual table? At the site that I am looking to move to, I have 4 gutter connected tunnels. I potentially want to fill one with DWC. The size is 10 meter wide by 40 meter long. What is the maximum size that you would recommend for an individual table?
