My hydroponic system
I would like to make my hydroponic system. For this I would use a pump, 2 bottles, some tubes and a bucket or something for water and nutrients. I also made a sketch. The arrows are showing the water direction. So the pump will pump the water to the plants and it will rinse through gravel or something like that. The plants are coloured green on the sketch. I would like to know if this system would work and does the water has to flow all the time? I hope someone can help me.
