HUMID HAVEN - Soil for Ferns, Calatheas & Marantas

Rs.499
GST 18% incl.

Crispy calathea edges aren't a humidity failure on your part they usually start in the pot.

Ferns, calatheas and marantas come from the damp forest floor and crisp the moment their roots dry out. Most mixes either dry too fast or, worse, turn water-repellent as they age so water runs straight through and the roots stay thirsty anyway.

Humid Haven holds one of the highest moisture reserves we make lab-tested at GKVK, Bengaluru at 1,950 g/kg kept safe by enough air (21% porosity) that the fine roots stay damp, not drowned. Our Mineral Lock system keeps it absorbing water evenly for the long haul. Consistent moisture, the way the forest floor delivers it.

Built for: Boston/Maidenhair/Bird's Nest ferns, Calathea, Maranta, Stromanthe, Ctenanthe, Fittonia.

Lab-tested (GKVK, FAO method): AFP 21% · WHC 1,950 g/kg · pH 6.40

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)

02
Fill one-third

Fill your pot to one-third with the substrate leaving the cavity of the plant, Plant the plant and fill the substrate completely

03
Water thoroughly

Water on first use to activate Mineral Lock and trigger Active Brain pH calibration and wait for 5 minutes
