I’ve personally used the SuperCube Hydroponic system with great success. The only problem that I ran into overtime was having the pump and water lines clog and stop working. This can be fix fairly easy by just replacing the pump and hoses every few month or so. This also really depends on the Hydroponic nutrients you use as well. My advice would be to talk to you local Hydroponic shop and buy the best nutrients you can afford that work with a resolver system like this. Otherwise you will be consistently running into nasty water problems. Also remember to change the water a few times a week.
