    About Grodan Rockwool
    Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirements of the plant through different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired.

    Caution: Do not exceed the recommended amount. Keep out of reach of children and pets.

    High Drainage

    Moisten Thoroughly before use: (optional) Peat moss can be water-repellent. Before use, thoroughly wet the soil.

    Potting:

    Use pots with drainage holes to prevent root rot.

    Fill the pot with the moistened soil, leaving enough space for the plant's root ball.

    Gently place the plant in the pot and fill in around it with more soil.

    Firm the soil gently.

    Watering:

    This is crucial! Water frequently, especially during hot weather.

    Check the soil moisture regularly by sticking your finger into the soil.

    Water deeply when the top inch of soil feels dry.

    Fertilizing:

    Since peat moss is low in nutrients, fertilize regularly with a balanced liquid fertilizer.

    Consider Amendments:

    For plants that prefer more moisture retention, you can add a small amount of coco coir or vermiculite to the mix.

    Important Notes:

    Overwatering: While frequent watering is necessary, avoid overwatering, which can lead to root rot.

    Plant Selection: This type of soil is well-suited for seed starting as well as plants that prefer well-drained conditions, such as cacti, cannabis, succulents, and some tropical plants.

    Adjustments: You may need to adjust your watering frequency based on the specific plant and environmental conditions (temperature, humidity, sunlight).

    Alberta Blend

    Moisten the Peat Moss before use: (optional) Peat moss can be hydrophobic (water-repellent) when dry. Before using it, thoroughly moisten it. You can do this by placing it in a container and adding water, then squeezing out any excess.

    Mixing: (optional) Our Private Label Alberta Blend comes ready to use, expertly formulated for your plants, either indoors or outdoors.

    If you're using this mix as your own base, combine it with worm castings, volcanic dust, vermiculite, etc. to improve nutrition, drainage and/or aeration.

    Potting:

    When potting your plants, ensure that the pot has drainage holes.

    Fill the pot with the moistened potting mix, leaving enough space for the plant's root ball.

    Gently place the plant in the pot and fill in around it with more potting mix.

    Lightly firm the soil around the plant leaving ½ inch to an inch of space at the top for watering.

    Watering:

    Because peat moss retains water, be careful not to overwater.

    Allow the top layer of soil to dry out slightly before watering again.

    Fertilizing:

    Since peat moss is nutrient-poor, you'll need to provide your plants with regular fertilization.

    Use the correct fertilizer according to the plant's needs.
