oh pooh pooh i say, why dont you live in a cave then Mr. natural?
im just teasing of course, but honestly, when a plant takes in water, does the plant care if the water came from a wooden bucket or plastic pipe? when a plant absorbs some nitrogen does the plant care if that nitrogen came from bat poop or an industrial factory? when a plant uses light does it care if those photons came from the sun or a lightbulb? no, it makes no difference in the plant as long as long as it gets what it needs/wants in the right proportions at the right times.
i also like dwc for its ease and simplicity, the only advantage of drip recovery is that you can grow more plants per bucket.
oh the very easiest grow i did was in this big long hunk of rockwool wrapped in plastic, about 6 inches high by 6 inches wide by 6 ft long. poked a water hose and an air hose into one end, sealed with hotglue, poked a drain hole in the other end, and poked the plants into the top. absolutely the very least fussy grow i ever did with a great harvest. when it came time to get rid of the big hunk of rockwool tho, it was really really heavy becuz it was all full of water, and you cant just throw it in the garbage, or bury it in the garden, so that aspect kinda sucked. i ended up cutting it in half and wrapping it in garbage bags and stealthy throwing it into somebodys dumpster. if it werent for that, and the unrenewability then i think it do it that way all the time.
