Hello Hoocho and all.
Ive been interested in hydroponics for a while now, years. Been making small DWC growths and such.
Now i wanna make a bigger setup and I dont like wasting X amount of liter water every time i need to change the reservouir of water.
Is there any way to recycle the water in a closed loop, ofcourse i need to top up the water when the plants use it up.
But if i just keep adding water + nutrients then after a while I will get a big % of either N, P or K in the water and that will just keep rising as I add more water and nutrients as the plants grow.

Is there any way to solve this? Im looking for both cheap and expensive options.
