What hydroponic system is better. Ebb and Flow or a dripp system? With drip system how do I controll how much is dripped? Also, should I have a recovery system or should I not reuses water. I'm concerned that the used water will have a lower concentration of nutrients than the resevoir and it will change the concentration of the resevoir to a different level than I want. Is this a legit concern?
Thanks for you help
