🔥 Cook Time Estimate
0-2 weeks
Your mix is light on amendments - ready to use immediately or after a brief composting period.
💡Why cook? Heavy amendments (blood meal, bone meal, guano) need time for microbes to break them down. This prevents nutrient burn and creates bioavailable nutrients.
🏔️ Layer Mode
Top 2/3: Light Base Mix Gentle for young roots
Bottom 1/3: Hot Super Soil Heavy amendments - roots grow into it
💡Layered Technique: Start seedlings in gentle top soil. As plants mature, roots grow down into the nutrient-rich bottom layer. No feeding needed!
Single Uniform Mix
All ingredients evenly distributed throughout the container.
