Micro 20 (20 x 20mmx20mm blocks)

MICRO BLOCKER

The micro blocker produces  20 tiny (20 x 20mm) blocks at any one time and was designed specifically to enable consistent and successful germination for those small seeds that need to be kept close to a heat source. It's simple and easy to use and will be a staple item for those looking to raise their own seedlings.

We recommend that once your seeds emerge you immediately transplant these micro blocks into our larger 2"/50mm blocks (4x2 BLOCKER) using the cubic inserts.
