Grodan MacroPlug Round with Slit (Bag of 50)

Grodan® Stonewool 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.

These rockwool plant starting plugs feature a slit for easy insertion of rooted cuttings. Ideal for growers using aeroponic EZ-Clone machines. They fit perfectly into the holes of any standard rockwool blocks, inserted into pebbles, or any other type of growing media.
