Jeg har fået et svar på hvordan vandet kan drænes/føres tilbage til vandreservoiret i dette her setup, men jeg forstår det stadigvæk ikke helt hvordan det fungerer. Om man skal købe en vand/akvariepumpe der suger vandet op ligesom en støvsuger eller hvad. Normalt bliver vandet jo bare pumpet op, men det skal også suges tilbage da plantebeholderen skal tømmes helt for vand efter at man har fyldt det op.
The drain system works with a venturi effect, Once it starts to drain and the pump timer goes off no more water goes in and all the water will continue to drain right to the tub bottom until empty. This system uses a simple gravity/siphoning action and there is no hole needed in the bottom of the tub. Your pump timer only needs to fill the tub (you can run it as long as needed) and then shuts off until the next watering and all H20 drains to the very bottom of the tub back into the nute reservoir where the pump is to be recycled for the next watering (or to waste if you prefer). It is simple and works every time.
