Plug Plant Starter Rhiza

Plug Plant Starter Rhiza is a peat-free substrate specifically formulated for the sensitive early stages of plant growth. Its fine, consistent structure provides with excellent aeration and moisture retention that support healthy, uniform rooting, making it perfect for seedlings and clones. The addition of beneficial rhizobacteria really sets it apart from other options — stimulating root development, enhancing nutrient uptake, and helping plants establish stronger and more rapidly. It’s unbuffered, giving growers complete control over their feeding schedule, with a clean organic profile that makes it ideal for growers committed to sustainable, organic cultivation practices, whether you’re growing at home or in a commercial setting. For high-volume propagation without the added rhizobacteria, Plug Bulk Basic offers the same consistent structure that allows for thriving early plant health. For smaller setups with rhizobacteria built in, check out Small Rhiza — delivering the same benefits for more compact grows.
