IMMORTAL DUO - Soil for Rubber Plant, Fiddle Leaf Fig & Aglaonema
If your fiddle leaf fig drops a leaf every time you look at it, the mix is the culprit, not you.
Rubber plants, fiddle leaf figs, aglaonemas and hoyas don't hate moisture; they hate swings. The soggy-then-bone-dry cycle of a cheap, dense mix is what triggers the dramatic leaf drop. They need a root zone that stays steady.
Immortal Duo holds a deep, even moisture reserve lab-tested at GKVK, Bengaluru at 1,840 g/kg water-holding balanced by structure (22.5% air-filled porosity) that keeps air at the roots, so it stays evenly damp instead of waterlogged. Our Mineral Lock system keeps it moisture-receptive for years, so it won't dry into the water-repellent block that ageing cocopeat becomes. Steady roots, settled plant.
Built for: Rubber Plant, Fiddle Leaf Fig, Aglaonema, Hoya, Begonia, Schefflera, Croton, Dieffenbachia.
Lab-tested (GKVK, FAO method): AFP 22.5% · WHC 1,840 g/kg · pH 6.42

What's inside
- LECA fluoride-free structural drainage, appropriate for fluoride-sensitive species
- Zeolite potassium retention for frond development; moisture reserve
- Perlite macro-pore aeration
- Mineral Lock™ moisture film for palm watering cycles
- Microbial Innoculent - moderate nutrition appropriate for palms; does not tolerate richness
- Activated Charcoal 700 IV 700 m²/g adsorption, pH buffer
- Active Brain sodium purge, pH calibration, long-term pH stability
How many pots it fills
One kg bag fills approximately six to seven 4 inch pots and three 6 inch pots depending on the pot size
Instructions
Step 1: Fill the substrate in the pot and tap it to make the substrate settle
Step 2: Water it until you see water drops coming from the bottom
Step 3: Wait for 5 minutes
Step 4: Water it again until the water starts flowing freely from the bottom (This will start the Ph buffering and the EC to come down)

How to use
Pick the mix engineered for your plant family. Each is formulated for specific native habitat conditions.
Fill your pot to one-third with the substrate leaving the cavity of the plant, Plant the plant and fill the substrate completely
Water on first use to activate Mineral Lock and trigger Active Brain pH calibration and wait for 5 minutes
Water the substrate until it drains freely. The substrate self-manages drainage, nutrition and pH for 1 - 1.5 years. No testing required.
