Styroblock Container
growing system

Stay ahead of the competition Put the latest innovation in silviculture to work for you. With the Styroblock container growing system, you’ll stay ahead of the competition with healthier plants and more efficient and cost-effective operations. No other system gives you such precise control over the growing regime.

Total control The grower’s advantage

Take your nursery operation to the next level. The Styroblock system brings the growing process under total control so you deliver seedlings that meet your customers’ exact specifications

Control Quality

Your customers demand seedlings of a specific size and root development. Using Styroblock containers, you achieve predictable results from greenhouse space. Seedling size is on target and on time.

Control Costs

Save water. The Styroblock container system conserves water, with runoff from foliage directed to the root cavity.
Reduce labour costs. Every step in the Styroblock container growing system is labour-efficient and can be automated to factory processes.
Increase service life. Styroblock containers are rugged, mirror-smooth containers that resist root penetration and ensure problem-free extraction.
Use heated space efficiently. Increase the productivity of your heated greenhouse space through high-density planting with Miniblock™ containers in the winter months. These starter containers hold up to 540 seedlings each that can be transplanted into larger cavity containers later in the season.

Control Risks

Gain exceptional disease control with Styroblock containers. Our containers are easily sterilized for years of reuse.

With Styroblock containers, you achieve:

• Intensive management of growing conditions so you can produce seedlings to precise specifications
• Uniform growth of seedlings with healthier root systems
• Root training to avoid root spiraling
• Maximum survivability of seedlings in adverse conditions because of stronger root systems.

Beaver Plastics is the only full-service manufacturer of expanded polystyrene containers for the nursery industry. We pioneered the proprietary molding process that yields the high-quality Styroblock container growing system – recognized as the leading technology in forestry nurseries around the world. More than seven billion tree seedlings have had a successful start in the Styroblock container growing system since 1970.

Attention to detail shows in every
Styroblock container

It’s easy to see why Styroblock containers are the industry standard in silviculture nurseries. Beaver Plastics pays close attention to detail in every phase of the design and manufacturing processes. All our products are rigorously field tested with our customers. Our R&D team includes professional engineers, engineering technologists, technicians and experts from the silviculture industry.

Ultimate flexibility. Styroblock containers come in a wide range of cavity diameter, depth and volume to meet your most demanding requirements. For high-density planting, try Miniblock containers with more than 2,500 seedlings per square meter of greenhouse space. If you have unique site requirements, talk to us about custom-designed containers.

Smoothest cavities. A key feature of every Styroblock container is the fused mirror-smooth surface in the seedling cavities. Along with an advanced cavity design that root trains seedlings, the smooth walls resist root penetration and ensure problem-free extraction.

Robust design. Every container in the Styroblock growing system has been engineered for high impact resistance, and tensile and compressive strength. This robust design ensures a long service life for all our containers.

Thermal protection. The insulating properties of Styroblock containers protect seedlings from temperature variations, enhancing the efficiency and predictability of the growing regime.

Safest handling. Smooth, rigid Styroblock containers are safe to handle, never cracking or leaving sharp edges that can injure nursery workers.

Key to automation. The Styroblock container growing system is the foundation for a fully automated nursery. The light weight and rigidity of Styroblock containers make them ideally suited to automated handling.

Environmentally friendly. Styroblock containers are totally inert, non-toxic and never give off harmful substances. They are CFC- and HCFC-free – which means absolutely no impact on the earth’s ozone layer. Reusable and robust, the containers can be used many times over.
