AC Infinity Instant Potting Mix – 2 lb Buffered Coco Coir for Seed Starting & Hydroponics

AC Infinity Instant Potting Mix is a premium 2 lb brick made from 100% organic coconut coir fiber. This soilless medium provides a clean, pest-free foundation with built-in stability for pH and EC, helping you manage nutrient uptake as roots establish. The compact brick is designed for easy transport and storage, making it simple to keep a ready-to-use supply on hand for ongoing projects.

When you hydrate the brick, the coco coir expands into a firm, well-aerated substrate that supports healthy root growth and steady moisture balance. This extra space gives roots room to spread while maintaining enough hydration to sustain young plants through their early stages. The medium is triple-washed and buffered with calcium, offering greater consistency in pH and EC levels to help plants access nutrients more predictably as they grow.

Why choose this coco coir for your grows

• 100% organic coconut coir fiber provides a clean, pest-free alternative to soil
• Buffered and triple-washed to stabilize pH and reduce salinity for better nutrient uptake
• Constructed to increase aeration while holding the right amount of moisture for root development
• pH-neutral foundation suitable for a variety of indoor and outdoor setups
• Expands to fill up to 3 gallons, with a compact 2 lb brick that is easy to store

OMRI-listed and designed for versatile use, this mix supports seed starting, propagation, and general root growth in hydroponic and soil-among setups. Whether you’re stocking a greenhouse, grow tent, or home grow shelf, the coco coir can help create a stable environment for young plants without the heaviness of traditional soil.

Ideal use cases and practical tips

• Seed starting and early propagation in pots, trays, or small containers
• Transplant readiness in hydroponic systems or soil-based gardens
• Indoor grow rooms and tents where control over pH and moisture matters
• Greenhouses and outdoor containers where a clean, low-pest medium is preferred

How you use it can vary by setup, but a common approach is to hydrate the brick until it expands fully, fluff the coir, and adjust moisture to your potting needs. The result is a reliable, resilient base that supports healthy root systems while staying easy to handle and store.

Pro tips for best results

• Mix with water to the desired moisture level before planting to minimize transplant shock
• Monitor moisture and EC if using with nutrient solutions to maintain stable growth conditions
• Keep the brick sealed when not in use to preserve its buffering qualities
