3 x 3 x 2.5 in. Delta 4 - Gro-Blocks with Hole 8 Blocks Per Strip - Grodan RWDM4G

Works like it should

I used this for some Galapagos seedlings to transplant to Coco coir and it kept them alive until transplanting.

GreT product, arrived cast, aand was packaged well.

Not cheap but works SO well

CANT GET ALONG WITHOUT THIS PRODUCT AND FAST SHIPPING THANK YOU

Works great

performed as expected

Delta-4 Gro-Blocks are not worth the money. When I received them they were all broken up with no way to support whatever plant you are planning to use it with. Purchase rockwool grow blocks at your own risk. You may not be able to use them when you get them.
