right a friend says its better to have run to waist than recycling as u dont get much ph flux on run to waiste.do u know of this way of growing.have u ever used it before?also i know it will use more nutrient but i thought it would be a good idea in the flush stage.so can u get me a attachment that i can fit a extension on the wilma plastic tube.then i can have a 50 liter tank next to it.then i can attach the extension on to the Wilma plastic tube then i wont be recycling the flush water.what do u think?
