dont really know how to put in words id have to draw a picture. but think about the water level in the buckets vs. the water level in the res. the buckes can be made higher and a tube can create siphon between the 2 it can be done. but im too high to explain. i was looking at waterfarms and its pretty simple thats a good way to go it is different from hempy but not that much helll you could simply add a water pump and drip ring to a hempy style bucket and make a water farm
