Full Substrate Replacement

Built on biochar from the ground up. Not amended. Engineered.

Four production blends for operations ready to replace their base media entirely.

Every Rosy grow media starts with a permanent biochar skeleton. The structure does not degrade, compact, or go anaerobic over time. What changes across the line is texture, drainage rate, and moisture retention, matched to the crop, not the other way around.

The Line

Four blends. One foundation.

All four are built on the same biochar base. Select by crop type and drainage requirement.

RS1

Production Blend

Herbs, Flowers & Vegetative Cannabis

The workhorse blend for high-throughput production cycles. Fibrous structure built for rapid root expansion and consistent wet/dry cycling under automated irrigation.

AFP 24–30%WHC 65–75%Stability Permanent

Best for

→ Culinary and medicinal herbs
→ Annual flowers and bedding crops
→ Vegetative cannabis
→ Short-cycle food crops
→ Microgreens and living trays

Inputs

Biochar, Sifted Bark Fines, Recycled Paper Fiber, Compost, Worm Castings, Kelp Meal, Mycorrhizae

Formats: 75 × 1 cu ft bags (palletized) · 2 yd Super Sack

RS2

Moisture Balance Blend

Houseplants & Tropicals

Balanced porosity and retention for crops that demand consistent hydration without sacrificing drainage. Eliminates the wet/dry volatility common in standard peat-based mixes.

AFP 20–26%WHC 70–80%Stability Permanent

Best for

→ Foliage and tropical houseplants
→ Ficus, Pothos, Philodendron
→ Interior plantscaping and interiorscape programs
→ Retail-ready repotting operations
→ Moisture-sensitive ornamentals

Inputs

Biochar, Sifted Bark Fines, Compost, Worm Castings, Mycorrhizae, Diatomaceous Earth

Formats: 75 × 1 cu ft bags (palletized) · 2 yd Super Sack

RS3

High-Drainage Blend

Cacti, Succulents & Drought-Tolerant Perennials

Maximum drainage for crops where standing moisture means root loss. A heavy aggregate matrix that moves water through the pot, not into the root tissue.

AFP TBD — confirm from RS3 TDSWHC TBD — confirm from RS3 TDSStability Permanent

Best for

→ Cacti and succulents
→ Lavender and drought-tolerant herbs
→ Hemp and outdoor cannabis (container)
→ Mediterranean perennials
→ Any crop where wet feet are a production risk

Inputs

Biochar, Pumice, Sifted Bark Fines, Compost, Worm Castings, Sand, Mycorrhizae

Formats: 75 × 1 cu ft bags (palletized) · 2 yd Super Sack

RS4

Coarse Blend

Aroids, Epiphytes & Long-Term Mother Stock

Chunky, large-grade texture for crops that need maximum air at the root zone and cannot tolerate compaction over long cultivation cycles. The biochar skeleton prevents structural settling in containers that run for months or years.

AFP 30%+WHC Low–ModerateStability Permanent

Best for

→ Aroids: Monstera, Alocasia, Anthurium
→ Epiphytes and orchids
→ Long-term mother stock
→ High-value collector specimens
→ Interior plantscaping with premium species

Inputs

Biochar, Sifted Bark Fines, Pumice, Worm Castings, Mycorrhizae

Formats: 75 × 1 cu ft bags (palletized) · 2 yd Super Sack
