Setting up a herb garden and plant home to make my kitchen cool. Ordered a 4 ft 6 bulb t5 fixture. The center will be herbs, then the surround will be my orchids, ferns etc.... My question is this, what is the chemical that you brush on the cut above a node? It seals it off and fights infection. It's a specific chemical, I learned about it randomly at a horticulture class. I'm searching the Internet, but everyone says something different. This chemical was powdered and you add water to make a thick paste and brush on cut. Thanks!
