Miksgrow MYY is a fine-structured peat-free substrate for sowing and seedling production in plug trays, seedling trays, and small pots. The smaller wood particles ensure smooth tray filling and close seed-to-substrate contact for uniform germination. Maintain even moisture and avoid saturation. The substrate re-wets efficiently and faster surface drying can help reduce the risk of algae and mold.

MYY is pre-fertilised to help minimise nitrogen immobilisation, but nitrogen levels should be monitored and fertilisation fine-tuned during active growth. When using MYY for the first time, monitor moisture behaviour in your system and adjust irrigation accordingly.
