Airstone for 60 gal reservoir
I have been using airstones in all of my DWC with great success, but never in 30 years have I ever used one in my 200 litre reservoir on my ebb and flow system.
With my Kratky method where I do not use any electricity my lettuces are doing very well .
I have good success but not great success with my ebb and flow except tomatos that seem to do very well.
I planted some Kale in my ebb and flow using the correct PH and EC for optimum growth, I gave some seedlings to my son who planted in his soil garden and they just rocketed in growth. Any idea what I should do and if you think an airstone is the way to go what size what you suggest
