Start a 20000sqm family business in Thailand - please help

[Willy]

well that is a first word and fully understood. Thanks Jason!!
In other forums there were also doubts about the flow rate and WHY a huge tower..
(My answer would have been: Because my test farm was built like that)
-Less electric: Lower height so the tower must go.
-Equal flow rate: valves have to be implemented
-OVERFLOW: Right, what happens when Willy goes to sleep and one tank getting the outlet blocked? It will create a lake over night and within hours there is no water in the grow throughs anymore, the pump runs on air.. Well a simple issue forgotten and the desaster would have been immense.

Now to get all under the grow beds is the next target, as wasted space in a Greenhouse costs money and not earns it.

But NO tower means saving electrics, if I wold not have such a success with my ebb/flood worm filter. Without tower this won't work anymore. I have to raise at least 3 filters then and so the others need to be raised as well and here the chain reaction is created until a 2nd pump has to be involved.
Are a couple of worms worth it to think further?



last, it will not beeing started at 20000sqm,,, phase 1 is 1800 sqm Greenhouse.

Thanks a lot for further involvements, really good thoughts in detail.
