What customers say
Customers overwhelmingly praise the Ladbrooke Micro Blocker for its superior quality and robust metal construction, viewing it as a long-term investment. The tool excels at creating uniform 3/4-inch blocks, which maximizes space and minimizes soil waste, making it ideal for microgreens and herbs. Gardeners value the sustainable benefit of replacing plastic trays. A key functional advantage is the air pruning effect, which promotes healthier roots and reduces transplant shock. While achieving the perfect soil consistency requires a brief adjustment period, users quickly master the efficient process. This high-quality device is considered indispensable for specialized seed starting, significantly boosting success rates.
Know before you buy
Soil blocks eliminate the need for plastic containers and prevent transplant shock. Because the blocks are open to the air, roots naturally prune themselves when they reach the edge, which encourages a stronger, more fibrous root system.
Yes. These mini blocks are designed to be 'potted up' into larger soil blocks, such as the 2-inch size, once your seedlings have developed their first set of true leaves.
You need a fine-textured, peat-based or coco-coir-based seed starting mix that contains enough organic matter to hold its shape. If the mix is too loose or contains large wood chips, the blocks will not hold together properly.
The secret is moisture. Your soil mix should have the consistency of damp cake batter; if you squeeze a handful, it should hold its shape without dripping excess water.
Yes, the footprint of the blocks is designed to fit perfectly within standard 1020 trays, making it easy to organize and water your seedlings.
The tool is robust and largely maintenance-free. We recommend rinsing off any residual soil after use and drying it thoroughly to keep the steel in top condition for many seasons.
