Sun Gro Sunshine Mix #5 Propagation Mix with RESiLIENCE - 2.8 cu ft - Loose Fill

Fine-Textured Propagation Mix for Root Development, 2.8cu ft

Seeds and fresh cuttings root best in a medium that holds moisture evenly around a small, fragile root system, which is a different job than the coarser drainage a mature container plant needs. Sun Gro's Sunshine #5 Propagation Mix is built specifically for that early stage, combining fine perlite and fine sphagnum peat moss into a low-drainage, high-water-retention blend sized for liner trays, cell packs, and flats.

This 2.8cu ft loose-fill bag ships 54 per pallet and includes dolomite lime, a long-lasting wetting agent, and RESiLIENCE, a silicon-enriched additive included across Sun Gro's professional mix line.

Frequently Asked Questions

What is Sunshine #5 designed to support?

Root development during propagation, for seeds, cuttings, and ornamental or vegetable transplants. It's built for that early stage rather than as a general container or garden mix.

What formats is this mix suited for?

Liner and propagation trays, cell packs, flats, and direct seeding, where a fine particle size and consistent moisture matter most. A coarser container mix isn't sized right for those small cell volumes.

What is Sunshine #5 made of?

Dolomite lime, fine perlite, fine sphagnum peat moss, a long-lasting wetting agent, and RESiLIENCE. Together they form a low-drainage, high-retention blend rather than the free-draining mix used for mature container plants.

How is this mix packaged?

This 2.8cu ft loose-fill bag ships 54 per pallet, sized for propagation-scale ordering rather than large-format container mix pallets. Loose-fill format also makes it easier to portion into trays and cell packs by hand.
