Hydroponics (rockwool drip system). How do I receive the drainage system on a large easy for little $ $ $? I have a hydroponic system using rockwool slabs and a system of drip irrigation. I wanted to know if anyone knows of an inexpensive and simple to collect drainage and pump in the tank. The tank is not under the system so I would need something with a valve and a pump.
You need a submersible pump and a hose. That will take care of all your problems. They range in price between $ 20 and $ 115 and you can get them at any store hydroponics or online. The price difference is due to the power and the clerk should be able to tell you what you need for your tank size and the height at which it is in. plug to a timer power to evacuate if necessary.
Remember to aerate your water, so if you do not, you can buy a stone from the Air and pump well. Again, you can find online very cheap.
Good luck.
