What you see above are refill packets we buy from the stores, usually food related. Since they are of good material, I use them mostly to start new seeds or keep small plants in temporary states. They are very handy. I cut or punch out a few holes in the bottom for drainage. In the picture above, last year I tried to grow extra mint cuttings. I tried this method by keeping them together. Initially they showed good signs but it did not work. I felt it required more nutrition. They did poorly.
