The product to substitute for wood would be Plastic and Tote Bins are available for resale in Udon with steel reinforcement cages on the outside
This can be used in Hydroponics also
The concern in the last posting was "Totally different - and impossible in the average back garden" and this was in answer to that concern of available land to have an aquaponics system
Hope this helps

plants just turn any chemical organic/inorganic into plant material, a bit like animals ,don't matter what they are fed ,as long as it's balanced you get the same result, even us rice/potato, chicken/fish we still grow basically the same. but thanks for that info on the feed and I will defo be trying them , cost/result/care are important when considering building. also consider this The majority of plant-available nitrogen is in the inorganic forms NH4+ and NO3- in soil, without bacteria and microorganisms organic nitrogen is unavailable to a large extent, nitrogen is basically washed out of the air when it rains and is absorbed directly as it's in a soluble form, and there is no difference between inorganic and organic nitrogen. for true organic you need to culture the soil, you need to put life into it so all the little microorganisms have a good environment to grow and keep your soil rich.

yes I understand, but the video is more fish than hydroponics, a tank of that size is massive compared to the amount of crops being produced, just a guess but that much water would produce hundreds of square feet and produce thousands of plants. I have no real interest in fish keeping . but if you are into fish too he's the basics on how many fish,
1 pound fish per 5 – 10 gallons of fish tank volume or .5 kg per 20-26 liters, as my tanks only hold 200l it would mean a max of 10 fish, plus looking at more filtration and cost in materials and work to maintain, deep water culture or nutrient film much easier and a fraction of the cost. I don't want to have to check everything every day, defeats the purpose. automated systems can't tell if your fish died last night and having to feed them 3 times a day (yes auto feeders) can help, but again more expense and even auto feeders pack up so you still need to check every day, which if you have a commercial set up is fine as it's your job. we are on about a system where most of my visits are to pick the produce or add water.
Anyway good discussion and hopefully some others will have a go at it , I will be going to look at a larger scale version of aquaponic system and find out more for you guys , also take some photos too

Thanks Dean but where?
