Beaver Styroblocks
The Styroblock Container System is flexible. Developed by professional foresters, researchers, forest nurseries, and Beaver Plastics, Styroblock containers have the ability to be modified easily and economically. If you have a novel container requirement, we can make it happen.
Superblock Containers are the industry standard with smooth, tightly fused cavities, diverse configurations, and the lowest cost per seedling. Superblock containers are the most popular tray in silviculture nurseries.
Copperblock Containers are manufactured with a patented differential coating technology that achieves the lateral root growth expected from a copper enhanced root system, while allowing the right proportion of vertical root growth desired for a cohesive plug.
