Know before you buy
Soil blocking promotes healthier root development by 'air-pruning' the roots as they reach the edge of the block, preventing the plants from becoming root-bound. This method also eliminates the need for plastic pots, making the transplanting process less stressful for the plant.
Yes, these trays are made from extra-thick, 1.8-2.0 mm BPA-free polypropylene. They are significantly more durable than standard, flimsy nursery trays and are designed to be reused for many growing seasons.
The side cutouts allow you to easily pour water into the bottom tray without disturbing the soil blocks or getting the foliage wet. This encourages roots to grow downward toward the moisture and helps prevent common issues like damping-off and fungus gnats.
The mini blocker is designed for starting small seeds that require less space initially, while the 2-inch blocker is better suited for larger seeds or for potting up seedlings once they have outgrown their first block. Using both allows you to manage the entire lifecycle of your plants from germination to transplanting.
Yes, soil blocking requires a specific, fine-textured mix that contains enough peat moss or coco coir to hold its shape when compressed. A standard potting soil with large wood chips or perlite chunks will not hold together well in the blockers.
While you can germinate seeds in this kit on a windowsill, most indoor-grown seedlings will become 'leggy' or weak without supplemental grow lights. For the best results, place your trays in a location with at least 12–16 hours of bright, indirect light or under dedicated LED grow lights.
