The dry mix combines coconut coir, vermiculite, and gypsum in precise proportions to create a substrate that can hydrate smoothly, maintain moisture, and provide a stable base for your monotub or tray setups. This is a practical option for growers who want a straightforward, scalable path from dry mix to fruiting stages.\u003c\/p\u003e\n\u003ch3\u003eWhat’s included\u003c\/h3\u003e\n\u003cp\u003eThe kit features three core components in measured amounts to simplify preparation. The coconut coir delivers texture and water-holding capacity, vermiculite contributes air pockets for gas exchange, and gypsum helps stabilize the mixture as it hydrates. This combination aims to offer a consistent starting point for a range of cultivation projects.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePremium CVG bulk substrate blend tailored for consistency across batches\u003c\/li\u003e\n  \u003cli\u003eOne easy to hydrate mixture designed for single-step water addition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to prepare\u003c\/h3\u003e\n\u003cp\u003eHydration is a straightforward step in a standard kitchen or workshop setup. In a 5-gallon bucket, add 16 cups of boiling water to the dry mix. After mixing, pasteurize the substrate for 24 hours to reach a stable field capacity. Allow the mixture to cool before introducing spawn as part of your cycle.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse boiling water for predictable hydration\u003c\/li\u003e\n  \u003cli\u003ePasteurize for 24 hours to reduce contaminants and establish stability\u003c\/li\u003e\n  \u003cli\u003eCool before proceeding with spawn-to-bulk transfers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eYield and versatility\u003c\/h3\u003e\n\u003cp\u003eWhen hydrated, the dry mix yields about 9 lb of substrate, enough for two full monotub grows or other fruiting configurations.
