The system as show uses rockwool. They usually use a system called 'Drain To Waste'. Not a recirculating system.
In a recirculating system such as ebb and flow tables you do need to do water changes.

Rockwood holds on to water too long. Rockwood is a material that must be in a closed system, with infrequent watering for this reason. For instance, not out in the rain, bc rain is unpredictable, and there must be dedicated time for Rockwood to dry enough.
What I like about clay pellets is, water always drains from them. You can use a sprinkler on it all day long, or let it be rained on any time, and it drains. Same with sand, pebbles or grow stones.
No people think they can re-invent the wheel. They come up with substitutes that are not as good as their successors.
When I see that, it seems that when something is broken or not described the way it is said how it's supposed to work, so parts of it have to be fixed. For instance, GPL, needs to be improved to have a clause that it doesn't force the absorption of dependencies it uses which are dynamically linked. That's a flaw, and a potential fix. It makes that software more compatible with other software, by also setting a clear boundary, which doesn't have to be explained by excuses.
Wow... that's a big industrial-scale setup, by the sounds of it. Interesting project. I wonder if they can look into filterting and recirculating some of the water to minimise losses. 50000 litres per day sounds expensive.
No shortage of wonga then.There isn't anything else to share right now. Clients like this are the type who have a large amount of expendable capital. They'll contemplate the most impressive idea they can come up with and then likely hand it off to us and say, "Make this work. This is how much we want to spend, and if you come in under budget, just make it more badass!"
Someone will be like "What does more badass even mean!!!" And I will be like haven't you ever seen a hightimes magazine? And they will be like no!!! And I will be like order some black lights and fluorescent markers!!!
I'm not even joking. That's literally how this is going to play out.
There are such measuring and control equipment that work in other conditions like that. There's equipment that works in boiler rooms, oil and gas processing, chemical manufacturing, and anything else that involves measuring or processing liquids and gasses. Food industry too, which isn't harsh. It's called Instrumentation, which uses equipment to measure temperature, heat and flow, and often sends this info to a computer or other controller. Often PLCs are used to control valves and such. There's other things which aren't about flow, pressure and temperature, which can be measured. The equipment to measure and control is often sturdy or can be serviced for harsh environments.
After looking that up, backyard swimming pools are typically 10,000 to 20,000 gallons, or 38,000 to 76,000 liters. I thought hydroponics would be more efficient in water use than traditional gardening, but that's a lot. And I hear that it costs thousands to fill a pool. That's crazy, and daily?
