Sunshine Mix

Sunshine Advanced Mix #4 is a professional-grade medium that prioritizes aeration and drainage. Unlike standard soils, it uses a coarse blend of peat moss, perlite, and coconut coir to prevent compaction, which helps roots grow faster and stronger.

It includes an organic starter nutrient charge to help young plants get established, but it is not a complete long-term fertilizer. You should plan to introduce your own feeding regimen once the plants are settled and actively growing.

Mycorrhizae are beneficial fungi that form a symbiotic relationship with plant roots. They help the root system expand, which improves the plant's ability to absorb water and essential nutrients from the soil.

While this is a high-quality professional medium, it is not sterilized or certified weed-seed free. If you are starting sensitive seeds, it is always a good practice to monitor your containers for any unwanted growth.
