Soil Block Maker Large 4 Cells

Soil blocking is a simple and easy way to start seeds in a home setting.  The Large Blocker is perfect for planting those larger seeds like squash and sunflowers. There are no pots or trays to store or purchase each year. We use trays with no drainage holes so it can be done anywhere indoors. We find that the seedlings are healthier, grow quicker and in general hit the ground running and suffer no transplant shock.
