I should really call it top feed not dripper. its just 1/4tubing and 6-1/4in T's to spread out the flow. I use the topfeed instead of hand watering them, but its bascailly the same as if I took a hose and hand watered them, but that takes time and is hard to do once shit get overgrown. now I just fill a 44gal rubbermaid brute, and plug in the pump for about 8mins until about half the rubbermaid is empty, then plug it in for 3mins the next days then drain it out the day after that
what I do it water day 1 until I see run off, then the next two days I water without runoff. so basically 20gal day one, 10gal day two, 10gal day 3, day 4 I hit about 10gal of straight ph'd water, then day 5 water again until I see runoff, and do it like that, so they only get water once a day really
I found with the hempys you cant constantly keep the bottom mini-res full.
after a watering with runoff I'll have about 2gals in the bottom of the black MPB tubs (and 1-gal in the 10gal colored tubs in the wk6 room) over the next 2 days or so they plant sucks that water out of the bottom, by watering only 10gal I keep the top part of the plant from drying out while not feeding it so much I waterlog the bottom. I could just water till run off every 3 days but I have been able to maintain my PPMs and PH because the plant never fully dries out , which causes the nutes to build up
