How to , The RECIRCULATING DWC System.

In this project we took the basic DWC idea and improved it.
we added a few changes and found better results.
we also decreased the depth of the pool, similar to shallow water culture.

Awsome. From a small city here in Brazil called Ibiporã

[@RetreatfarmFarmvilleVirginia]

I Wish my greenhouses were bigger, you can't do things like this in a 14' x 32', i would have to split the tank into two 6 foot wide tanks 25-32 foot long. I Got a much needed shot of encouragement from your video. I'll probably go broke but i'm gonna try it. I Do have 3- 950 gallon aquaculture tanks to play with also. All i need is a simplified design.

[@avamaria8447]

You've been so generous in answering all these questions all these years. Thanks for your patience. The floats, they are polysterene ? If so are they they regular ones from the hardware store? Thanks again.

[@AHhydrogrow]

Yes they are regular Styrofoam, But if you can get a high density Styrofoam it would last longer.

You have to use siphon drainage system. It's automatically drain when it's come to overflow. Siphon drainage system doesn't required any electricity.

What is the purpose of the blue vertical pipes at 6:26 ? Also - the fluid re-enters the tank at the top. Does it also flow down to the sump from near the top? Otherwise - what stops it from all draining into the sump? Is there some sort of valve anywhere that does this?

Hello! how are you? Thanks for sharing these videos, they are great! How does ph behave with the reduction of water in your system? Thank you very much!

[@AHhydrogrow]

The ph remains quit stable and although the amount of water has been reduced it is still a large body of water.

[@renzomastrascusa762]

Thank you very much for the answer! when the water level drops, you put in water and adjust the ec? or do you put prepared solution? sorry for so many questions and thank you again.

[@mannyliad8660]

Good day,new subscriber here,do you use fish tank or SAP solution for your set up,ty.

[@AHhydrogrow]

we use a basic hydroponic nutrient solution which you can find at a hydroponic store

[@chandrsrinivas]

Hi what u do when rain water enters in to the system? Thanks in advance...

[@AHhydrogrow]

we do have overflow outlets on the sump tanks so the water level remains the same. The only problem is that the nutrients are diluted after the rain which is not a big issue and can be resolved easily.

[@chandrsrinivas]

Any particular reason.. Rdwc you would consider instead of vertical tower?

we found better and faster growth plus our crop size was much larger comparatively using the RDWC system but this is on a personal level some people have found great results using the vertical system.

[@francisroda3360]

Thank you, this video is really helpful. One question. Does the roots always submerge in water?

[@AHhydrogrow]

Yes, but not completely underwater or the plant will drown, There has to be a small gap between water and top of the net pot which is not underwater, this usually is the case because the polystyrene which is 200mm or more allows this breathing area for the plants roots if not then your water level should be lowed to allow for this gap.

What temperature range do you have in solution?

[@avamaria8447]

not quite understanding the build. I see you mention floats...is the styrofoam holding up the lettuce in the netpot on top of the water on the table? Is the table built at a slight slant? also is the table ever drained of water or just recirculate when the plants are growing? I have space in my yard I could do this but not sure I understand fully

[@AHhydrogrow]

Regarding the floats, Yes the Styrofoam holds up the net pots with the lettuce they basically float on the water. Is the table built at a slight slant? No it is as level as possible (otherwise one side would have alot of water and the other little to no water) Is the table ever drained of water? occasionally we do drain the water but in reality the water is always being replenished by the plants consuming most of it or the sun evaporating it we are on a daily basis filling/topping up the system. And we do recirculate the water also.

[@avamaria8447]

@@AHhydrogrow thank you for all your answers...only just seeing them now.

[@Cicolino68]

Hi! Thanks for sharing your videos! Could you please explain what do you mean when you say the system should be drained up every 14 days?! Should the grow bad became empty of water, and filled up again with fresh water? Should the recirculating pump be working all day long 24/24 nonstop from the beginning (planting) until harvesting? Thanks in advance for your reply!

[@AHhydrogrow]

As was mentioned in the video its recommended that you change the water but not entirely necessary if its above 1000L and your plants are doing well, in that case you can change it every month or two or when you feel necessary depending on your system. by change I mean drain and fill new water. No the pump can be turned on at leased 4-6 times a day for about 5+ minutes

Beautiful build and excellent looking plants. How deep are your beds? Looks kind of like what I call shallow-water culture. Honestly, though, all the lines are blurred these days. Nice looking setup!

[@AHhydrogrow]

Thanks, The beds are not very deep, about 3 to 4 inches (it is in fact a shallow water system) . But people are accustom to the name deep water culture (DWC) so not to confuse I left it as RDWC , the only difference is the depth.

One quick question. How do you manage the EC level of your solution when you have various growing stages. I know that plants requires various solutions strength according to their growing stages.

you have to test the EC regularly sometimes every second or third day to know what the plant needs especially when the plants are maturing
