The Macro plug is a cylinder-shaped rockwool plug with a slit down its side. Absolutely perfect for taking cuttings because you can spread cloning gel inside the cube through the slit and insert your cutting into it.
The Macro plug also fits the super popular EZ-Clone machine. This allows growers to make clones in the EZ0Clone using the Macro plugs and then putting the Macro plugs directly into rockwool cubes.
All rockwool cube,s including the HUGO blocks, have cut out holes in the top which the Macro Plugs fit perfectly. These are a “step-up” from the 1″ square cubes.
Measures approx. 1″ wide x 1.5″ deep
