Video description

Let’s visit Tom who built a hybrid aquaponics system in a backyard greenhouse. Tom is based in Melbourne Australia. He is opening us the door to an interesting system composed of both a flood and drain grow-bed aquaponics and a Deep Water Culture aquaponics.
The fish tanks are composed of 2 in-ground IBCs (Industrial Bulk Containers) covered by a nice decking. You actually don’t see the tanks when you enter in the greenhouse as they are literally below your feet. Tom is currently growing Australian native fish such as eel tail catfish, Murray cod and Golden perch. He plans to later add trouts into the system.
He simply has to lift the decking/tanks lead to have access to the fish. The setup is very neat and tidy.
Tom choose to divert the water flow from the water pump in the fish tank to 2 different growing setups.
1 The flood and drain growbed section composed of 2 growbeds equipped with a bell siphon and clay balls as media. Those 2 Growbeds are producing very well and we note a very large sweet potato plant is currently transforming the greenhouse into a jungle.
2 The Deep Water Culture section is composed of 2 raft tanks equipped with air stones. The polystyrene rafts are floating on the surface and supporting pots where plants are growing.
Tom has noted that the DWC works extremely well with leafy vegetables while the Growbed technique seems more adapted to fruit plants.
We thank Tom for his time and congratulations again for the very nice system. Each square meter of this greenhouse has been optimized and will allow a nice food production.
Tom is also working on other solar systems to power the greenhouse so we will probably see him again in future articles and videos :)

Great video! Nice to compare and contrast systems and methods. It's always beneficial for the kids to be involved in this project.
Thanks Cheveau, very true! Have you got kids involved in your aquaponics project too?
Great vid
Thanks Christopher! Once again thanks to Tom for the invite! Very inspiring

Wonderful setup love the gas struts and watching the enjoyment you and others get from aquaponics.
Thanks Wayne, Tom has done a great job on this one. compact and efficient!
I'm not sure but ,if anyone else needs to find out about
cost of aquaponics farm
try Proutklarton Surviving Instruction Plan (should be on google have a look ) ? Ive heard some amazing things about it and my colleague got amazing results with it.
Great video Jonathan.
Jonathan, I have noticed one thing in aquaponic system from many people.
Generally in Aquaponic, the water flows out from the fish tank to the filters than to the grow bed/DWC/ NFT system, then to the sump tank and from sump tank, the water is pumped out to the fish tank again to complete the cycle.
But I have noticed that people are using a pump in the sump tank which will pump the water to the grow beds and the fish tank simultaneously by dividing the water to the fish tank and grow bed. Water comes out from the fish tank to the filters, then to the sump tank. and then pumped out to grow bed and fish tank.
What I think is, the water has just come to the sump tank from the fish tank and the nutrient rich water is going back to the fish tank again(at least partially because the nutrients rich water have jsut come to the sump tank from the filters)
Sorry for the confusion as I am confused and has doubt on this.
Hello Umesh,
very interesting question.
When we design the water flow we take several points in consideration, here are a few:
1. try to work with gravity as much as possible which means avoid using 2 pumps and avoid height.
2. If you are using a filtration, get the filtration between the fish tank and the grow-beds so that you are only sending clear water to your grow-beds. If you have a DWC, this point is very very important as we don't want particles do stick on the plant roots.
3. A sump tank help to position the elements as you like and have the pump in a safe and accessible place.
Cheers :)
@@AquaponicsRevolution Thanks Jonathan for the explanation. I am planning to build a bigger Aquaponic system and I am planning to make Sump tank underground which will help to maintain the temperature.
Here is the cycle: Fish tank -> Mechanical Filter -> Bio Filter ->Grow bed/DWC -> Sump Tank -> Water is pumped to the fish tank using pump. Water from the fish tank will flow using Gravity to the mechanical filter. then it will go to the bio filter and then Grow bed and DWC. Then water will collected at the sum tank. and finally pump will be used to pump up the water to the fish tank. But I am not pumping this water from the sump tank to the grow bed/DWC.
Now after looking at coupe of videos from different experts who is using pumping water to the grow bed and fish tank simultaneously, I got confused a bit which one is better. The complete cycle as mentioned above or pumping water to the grow bed and fish tank simultaneously.
Great Vid Jon
Thanks Tom, great work! Can you respond to Brian's question above? Thanks mate :)
*Does your self-sufficiency plan include a backyard greenhouse aquaponics as well?*
Great vid Jon & lovely set-up Tom. I do organic hydro in the UK & am going to try aquaponics in a polytunnel soon. Btw Jon I use fermented citrus insecticide which works great on all plant predators (ones with wings & 6 legs!).
Please can I ask how deep the clay balls are in the media beds?
@@sarahgodfrey3892 They are filling the whole depth (approx 30cm)
Thanks Sarah, very interesting, what is your recipe for the fermented citrus insecticide?
Melbourne Aquaponics you only spray it in the dark or it will kill the plants. Recipe: 2 cups citrus peel, 1/2 cup brown sugar, 1 tsp yeast, 4 cups water. Ferment for 2.5 weeks. Strain & add 1 cup of apple cider vinegar. Dilution rate: 2 cups of ferment per gallon of water. Although I have made this slightly stonger for stubborn infestations on more mature plants.
@@sarahgodfrey3892 Oh yes I see, the plants must love it as well :)
Thanks for the very good tip Sarah!
Would you recommend fresh water prawns as well????
Sure, just make sure they can hide and not get eaten by the fish :)
Waow! what a backyard setup... this guy has done a lot of research it's obvious :) I like the underground IBCs... Mr. Peng had him inspired :) By the way, where is Citizen Peng? Do you know if everything is alright with him?
Hi Jason, Thanks for the message. Mr Peng is working on a new greenhouse project.
Have you got a question for Tom?
Cheers
@@AquaponicsRevolution Just send him my regards and wishing him all the best in the new project (we miss seeing him on TH-cam) :)
great set-up, clearly a lot of thought and work went into this project. Has Tom calculated ballpark time and cost to establish and maintain?
Good question Brian, Tom will probably respond directly.
@@AquaponicsRevolution putting the tanks under the greenhouse floor is genius; what treatment does Tom do to water used for topping the tanks off?
@@brianrollins3245 He collects the rain water from the greenhouse which is great :)
I have plan to build an aquaponic system with the same greenhouse as Tom. Very good setting. Any chance that I can get more details on Tom's setup ? Underground fish tanks is genius as I have been wondering how to manage my fish tank temperature due to Melbourne weather.
Hi Albert, yes ask your questions and Tom will respond when he has a minute :)
What is the make and size of the glasshouse please ?
How big is your greenhouse? My friend
