BioSmart Felt Pads

BioSmart felt pad is a light substrate pad made up of degradable bio polymers with natural fiber. The company did not disclose the material used in the making of this growing pad.
By far, It’s one of the most popular growing pad for the common microgreens such as the arugula, kale, and mustard. Although it’s said to be biodegradable, they are not for backyard composting as it can take a long time to degrade.
