I was also wondering about this system. It looks like a hybrid NFT/SIP system using NFT channel to recirculate a nutrient solution under the bottom of the pots which waters the soil using capillary action, whilst any roots that grow through the bottom of the pots into the channels would be nutrient film fed. The drying action of the air pots is what draws the nutrient solution up from the bottom.
I may have the wrong idea, but if it is what I think it is, then my main advice - because I've experimented with hybrid soil/hydro systems in the past - would be to ditch the soil and use straight coco with an organic-based nutrient solution. The main reason is because it's hard to balance the nutrient solution when the soil in the pots also contains nutrients.
A wise many once told me "Never underestimate the nutritional value of soil".
Another reason is that soil can fall into the nutrient channels and eventually foul your lines or pump (though this can happen with coco, as well - ask me how I know!). The soil that falls in can also upset the nutrient balance in the reservoir.
Now, both these issues can be managed if you keep an eye on things, but one final thing you need to remember is that SIP systems - especially nutrient-fed systems (as opposed to plain water) - are very prone to salt build-up/nutrient toxicity. What happens is, the nutrient solution gets sucked up through the pots through capillary action and then dries out, leaving any unused salts suspended in the soil/medium. Your plants will continue to feed, but the nutrients they don't use will continue to build up in the pots.
This is a gradual process that is not apparent at first, until you start to see a salt build-up on the surface of the pots, or your plants show signs of toxicity.
A very good example of this in nature is the type of salinity you see around farmlands where trees have been cut down and the water table rises, bringing salt and nutrients to the surface, where the water dries out leaving the salts to toxify the surrounding soil.
With a top-fed system - drip-fed soil, coco or recirculating hydro etc - there is no nutrient build-up, because each watering action flushes the pots (well, there is a small amount of build-up, but that's for another discussion). So the solution to your system's potential problem is to ensure you flush your pots regularly with plain water from the top, and change you nutrient solution regularly (just like you do in DWC and other water cultures).
If there is something I've missed, then please allow me to apologise in advance. But here's an idea: if you want to continue growing with soil - or even organic coco - you could run a drip-feed or timed irrigation system to the top of the pots, fed by a reservoir, and use the NFT channel to collect and drain the waste - effectively turning it into a run-to-waste (RTW) system.
Contrary to popular belief, a good RTW system will use less nutrient solution than recirculating hydro and is much more reliable and vastly easier to control nutrient levels - because your plants get fed a fresh batch of correctly balanced nutrients each watering, whilst the waste nutrient is flushed away.
Just my 2c based on lots of years of growing many different ways . . .
Amazing work and beautifull photos. 
. Next time I'll try to put 8 plants in maybe in smaller pots as I dont think those got fully filled with roots. At least it doesn't look like that when I stick my finger in the top of the pot.
I've purchased Jecod AC2500. Very similar pump (low wattage) but without the stupid controller. Don't ever buy anything with the remote for the tent. K.I.S.S. . Simple works
