That is so funny you ask that because that was my biggest concern with the buckets. It isn't bad at all, way easier than you would think. When they get really big, or If i gotta tie em up, I have 2 buckets equipped with "Sight tubes" that I use to suck my juice from with my shop vac, and then add new nutes from the top, without moving the plantHow much of a pain in the ass is it swapping out buckets with the tall ladies? Seems like a lot of moving things around.
The nutrient line I use calls for " gentle circulation, and not airstones" ... so i just cut holes above the air stone and let it do big bubbles.
