Thank you very much for the education! Is it possible that you show us the whole system with the waterpumps and airpumps and explain us the whole system im very very interested about it :)
AH Hydro. Been waiting for this video for a while. Had even dug out my holes for the table stands, then I realized I couldn’t figure out the depth regulator. Mystery solved. I have one question. Following the exhaust piping from the table to the regulator I see you have a T-junction with an outlet pointing downwards - just before the regulator. How come the solution doesn’t flow out at this point? What is the purpose of the T-junction? I just can’t figure it out - is it the drain when you want to empty the entire table? Do you drain to a reservoir? Waiting eagerly on the nutrient solutions.
Do you have any plans on how this works/ how you built it? I'm having a hard time finding info on a rdwc set up with a pond instead of buckets. Any help would be greatly appreciated!
Thank you very much for this sharing, it was very helpful 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
The tube/pipe size will depend on how big your system is, we have a large system so we had to have 3 large regulators. Basically your outer pipe should be about 3 times bigger than the inner pipe (if your inner pipe is 50mm then your outer pipe can be 150mm) , which you can source at your local hardware together with T-fittings, elbows etc. by following the diagram drawn in the video it should be easy to build, let me know if there are any more questions. Thanks
@@AHhydrogrow But how did you make that inner pipe in the stand pipe go up and down? I was expecting you to pull that inner pipe out and replace it with a new length of pipe to change heights - but instead you were able to change the height of the inner pipe just by pushing on it. How does that height adjustment on the inner pipe work? Also, what is the advantage of adjusting height with the separate standpipe mechanism instead of just making the drain pipe taller inside the bed? Its a very cool system - just wondering from Ohio, USA I have never seen a hydroponic channel as well done as this - you have tried all of the systems and done each of them well. Thanks for all the information!
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 maen sir the suction from the sump tanks. You told that in one table have 3 sump tanks and one pump. Can you explain where did you put the suction of the pump? And this sump tanks are a couple or individwal suction? And where did you put the couple line if they have thank you.
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?
We use an air compressor which oxygenates the 4 systems and it comes on with a solenoid valve whenever the system does a circulation, The air is fed with the water through 4 venturies in the tables. Our tables are approx 6m by 10m. Considering working space I would suggest that you work around 7m by 15 meters x2 DWC systems which will give you 190 m2 of working space (This is a suggestion if you feel you do not need as much working space you can always decrease it. But remember the bigger your system the more working space you will need.)
@@AHhydrogrow Thanks for the quick answer. If you are in SA, I would like to contact you once I am there if thats ok with you. Maybe you can drop me an email at tofofresh [at] gmail [dot] com.
I would be very interested in learning from you do you do courses or I would work for the experience for free I'm seriously thinking about doing this in Madagascar
It does not prevent the rain from entering the system at all, but we do have overflow outlets on the sump tanks so the level remains the same. The only problem is that your nutrients are diluted after the rain which is not a big issue and can be resolved easily.
@@AHhydrogrow Hello there, I have become a fan of your work. Great amount of work you have put in to get this far. Good job. I am planning to do this on my roof, with three stories. Obviously leaving enough room for both light and air to pass through. Your videos will aid me a lot in successfully completing the project. The only thing I am worried about is how to control the nutrients and pH level. By the way I am located at the suburbs of Dhaka, Bangladesh. And I am a teacher by profession and have no experience in horticulture.
That would differ greatly depending on your location I would suggest listing all the materials and their price locally and by that you should have an estimated total cost.
