FB 29 are brown mushroom blocks intended for winter mushroom cultivation. They are made from a high-quality substrate and contain all necessary micro- and macro-elements, ensuring stable fruit growth.
Fruiting begins approximately 30‑40 days after planting, allowing for a quick first harvest. Under optimal conditions, each block can yield between 6 and 8 kilograms of ready product. The block dimensions are 35 × 45 cm, and the weight is about 14 kg, making it convenient for transportation and storage.
The blocks are designed for use at compost stage 2, where they decompose quickly, creating a favorable environment for mushroom spore development. The production technology does not require sterilization, which reduces costs and simplifies the substrate preparation process. Thanks to these characteristics, FB 29 is a reliable choice for both professional farmers and home mushroom enthusiasts.
