This works well and is lightweight. The reflective material is very shiny and is a thin stiff film of plastic or metal.
I only use this on all my roses and I have six plants and they do respond when they are fertilized with this
I use this plant food all the time on all my vegies
This product is great and I use it to start all my spring and summer plants
I have several of these. They perform wonderfully and are not expensive to run.
