A Cool Device for Plants
I have a melon sword that was wonderful when I got it, but over 3 months, it spread out so the leaves go out horizontally and cover half of the tank bottom so nothing else can grow.
I came up with a way to train the plant. I took a large round clear plastic peanut butter jar and cut off the top and bottom. Then I placed it over the plant with the leaves going up through the tube. Now they are being trained in the direction I want them to grow and it doesn't even look bad in the tank while they are being trained.
