• Improved drainage, allowing excess water to drain away.
• Increase in aeration around the roots by approximately 40%, preventing overwatering and reducing root rotting.
• Less soil compaction, especially in clay based soils.
• Superb water absorption and air management providing optimum water and nutrient uptake by seeds and plants.
• Increase in available nutrients to the root system.
• Use less fertilizer. Rinnal substrate will hold the added fertilizer to make it available to the plants.

Your potted plants will flourish on less water and suffer less heat stress with Rinnal substrate.
Step 1: Take your bag of Rinnal growing media to the planting area. Open the bag and soak thoroughly with water, or make a small hole in the bag and insert hose to add water to avoid airborne dust.
Step 2: Place a 1-inch (2.5cm) layer of Rinnal growing media in the bottom of the basket, or a 3-inch (7.5cm) layer in a pot. The permanent 35% air availability in Rinnal growing media prevents your plants from drowning in the event of overwatering. For hanging baskets, layer the Rinnal growing media up the sides of the basket.
Step 3: For optimal results, we recommend using a mixture of 50% Rinnal growing media and 50% soil. Mix thoroughly.
Step 4: Put some of the pre-mixed Rinnal growing media and soil in the basket/pot.
Step 5: Place the plant in the basket/pot and fill around the sides with pre-mixed potting mix and Rinnal growing media.
Step 6: For pots and hanging baskets placed outdoors, we recommend covering the top layer with potting soil only to prevent the Rinnal growing media from blowing away.
Step 7: The first time you water your plants, we recommend using a mixture of Organic Fertilizer and water. This ensures that optimal plant growth bacteria are immediately available in your soil.
When using 50% Rinnal growing media to 50% potting soil ratio, your plants require 50% less water than if you were to use 100% potting soil. If you overwater your plants, this is not a problem, as the bottom layer of your soil consists of Rinnal growing media only, and this will manage the excess water. Store unused Rinnal growing media in a sealed bag in a well-ventilated area to avoid moisture and mould growth.
Step 1: Take your bag of Rinnal growing media to the planting area. Open the bag and soak thoroughly with water, or make a small hole in the bag and insert a hose to add water to avoid airborne dust.
Step 2: Pre-dig plant hole to required depth (this should be approx. twice the size of the plant root system), and place a quantity of loose soil at the bottom of the hole.
Step 3: Using the container that the plant came in, place a ¼ of a container of Rinnal growing medai in the bottom of the hole.
Step 4: Position the plant in the hole ready for the backfill soil to be added.
Step 5: Fill the hole with water before backfilling. Place another ¼ of a container of Rinnal growing media with the backfill soil and mix thoroughly.
Step 6: Backfill with the mixture of soil and Rinnal growing media.
Step 7: Mulch thickly, avoiding the trunk of the tree.

Rinnal growing media is a lightweight man-made substrate that is biodegradable and compostable. Its structure allows plant roots to grow easily through it encouraging extensive root growth. Healthy roots means your plants will grow bigger and stronger.
Rinnal growing media does not contain any nutrients. However, it's designed to hold water, and consequently it will make the nutrients you add to water available to the roots. To start off, once a week apply a mixture of a suitable fertilizer and water to the soil of your plants. Depending on the plant progress, alter the frequency if needed. Avoid spraying the fertilizer mixture when the plants are in full sunshine.
