Gro-Blocks™

Please see Growing tips for detailed instructions.

Gro-Blocks™ are similar to a ‘plant container’. Need a 3” pot? Then choose a 3” Gro-Block. Small plants can be fully grown in our larger Gro-Blocks. Holes are perfect size for any 1.5” starter plug. The bases of the Gro-Blocks are grooved to promote drainage in order to avoid "wet feet". Comes in strips labeled with instructions.

Look under Other products to see plastic containers for blocks and nutrient testing syringe. Check our Coco-can caps to reduce algae growth on the Coco-can page.
