Looking good. Nice set up @mothergoose.
I especially like the cone bottom reservoir.
I respect the initial investment to do it right and get good equipment and food grade plastic.
The possibilities to make this a hybrid grow of full synthetics and organics heck yes.
Crush it!!!
Have you ever tried foliar feeding or foliar feeding with a microbial tea or sulfur?
With clay pebble medium and hydro, the key is foliar and putting biofilm on and under the leaves how we do it.
