Why Us

Four Reasons Growers Choose Sunselin Blocks

Yield and consistency start long before fruiting. Here is how we control every stage — from strain to substrate to environment.

01 — Strains

Japanese Strains by Hokken

We maintain a strategic cooperative relationship with Hokken Co., Ltd., Japan. All our fungus block production utilizes Japanese sawdust-based spawn imported from Hokken — a key factor in achieving high-quality output.

This cooperation provides us with high-quality strains and comprehensive technical support, ensuring our production standards fully meet international requirements.

Premium Oak Sawdust & Organic Bran

Our substrate formulation uses premium oak sawdust sourced from Northeast China, combined with organic bran supplements.

High-quality raw materials are the foundation of vigorous mycelium growth and stable, high yields — flush after flush.

Fully Automatic Lines, 121°C Sterilization

Two fully automatic production lines cover mixing, bagging, sterilization, inoculation and sealing. Each line produces approximately 1,080 blocks per batch with an average weight of 2.5 kg.

Substrate is steam-sterilized at 121°C, then inoculated and sealed automatically — minimizing contamination risk and human error.

We continuously invest in advanced equipment to ensure efficiency and consistency at every step.

Climate-Controlled Growing Houses

Our cultivation houses are steel-structured buildings with insulated wall panels, equipped with independent air conditioning, total heat exchange ventilation systems and supplemental LED lighting.

A real-time sensor network monitors temperature, humidity and CO₂ concentration, creating optimal growth conditions for different mushroom varieties.

Our technical team applies digital management to precisely regulate the environment, ensuring mushrooms achieve maximum yield and quality.
