I also use the used gallons to plant other vegetables.
I also related this best methods of Gardening Ma'am @anggreklestari , I collected lots of empty big gallons of mineral water and I also cut into half. The reason why I did this is to have lots of space and I can carry and transffered to other place very easily. As I watched your video Ma'am, this can bring lots of ideas to all especially those who love gardening. I really appreciated and very much inspired. ☺
