MacroPlugs™ are 1.5 in round with a slit that allows easy insertion of a cutting. These loose round plugs fit perfectly into the Gro-Block™ hole. For best results always insert MacroPlugs™ in a tray with individual cells. The individual cell will make sure the plug stays closed around the stem of your cutting.
