Plug Bulk Basic

Plug Bulk Basic is a reliable, peat-free substrate designed for large-scale propagation and robust plant development in early veg. Ideal for commercial growers, this mix supports fast, consistent germination and strong seedling structure across batches. Engineered for high-volume tray systems, this plug mix has an excellent balance of air porosity and moisture retention that gives young plants the best environment possible for uniform rooting. With a stable, organic structure that prevents compaction and promotes healthy root zone oxygenation, it significantly reduces the risk of damping-off and other early-stage issues. Unbuffered and free from synthetic additives, it offers a clean slate for custom feeding or using organic nutrients. If you're looking for added biological support, Plug Bulk Rhiza includes beneficial microbes to boost early growth. For small-scale starts or home growers who want the same great structure in a more compact format, Small Basic is the perfect option.
