Thanks. This is the a big step up from my last one which has been demoted to basement duty.

Jebediah Springfield suffered a similar fate.

Hypothesis: McRibs are Mothman meat.

I’m glad I switched from soil. No more hand watering is what convinced me. Just get a good pH/ec/ppm meter and you’re golden.

I only fill the res to 30 gallons. This is my second run with this setup. The first yielded a pound dried and trimmed from 4 plants in the 3x3 tent. Used about $80 of nutrients.

I drain the water weekly with a good sized Harbor freight pump, rinse/wipe it down, then refill and add nutes.

This is actually an ebb and flow bucket system with a black 55-gallon plastic drum as a reservoir. I haven’t been keeping up with water usage lately, but it’s a few gallons/week once the plants are really going.
