Pot4 Professional Basic

Pot4 Professional Basic is a dependable, peat-free substrate designed for strong structure and reliable performance throughout the vegetative stage. With a medium-density composition, it gives plants excellent support to develop strong, healthy root systems while maintaining excellent drainage and aeration. Perfect for potted cannabis plants, it enhances healthy plant growth without becoming compacted or waterlogged. Free from synthetic additives and unbuffered, it gives growers a blank canvas for custom organic feeding regimens — making it especially beneficial for growers who want complete control over nutrients and microbial inputs during critical growth phases. If you’re looking for something to enhance microbial activity and nutrient uptake, check out Pot4 Professional Rhiza — containing beneficial rhizobacteria with the same trusted base. For growers working with younger plants or that need a smaller volume with similar characteristics, Small Basic is a more compact option of the same clean formula.
