Salutations Corgy, Although i don't plan a change of bucket system anytime soon: 1) because i've put my hobby on hold for the most part; 2) i've found a perfect fit to my particular needs, which are to remain somewhat mobile and yet provide sufficient substrate volume - though not too much since i'd also wish to limit plant size, ideally. So, the 1st video is only about the Air Pot vs the Smart (fabric) Pot while the second sample got 6 types and yet none corresponds to what i've adopted, for years to come if i ever grow something again. Additionally, i used to keep my top soils dry. I like having a layer of colour aquarium rocks for multiple reasons including that one. Good day, Have fun!!
