Grow Cubes

Coco Earth Harvest’s Grow Cubes are professional grade seed starter cubes created of super washed and high-grade coconut coir. These small growing blocks can be placed in the Gro-Smart tray, module trays, or any other type of 10 x 20 tray without holes. They offer the advantages of excellent aeration and moisture retention, and are available in a clean, convenient compact size, all without the mess of traditional types of growing mediums.

Designed for home and professional use, such grow cubes let you get your garden started with a sense of assurance, whether you're planting vegetables, herbs, or flowers, or running a hydroponics setup.

Made from Premium Washed Coir

The Grow Cubes are made from super-washed coco coir or in other words, super clean chunks of a renewable byproduct of the Coconut industry. The fresh water rinsed coir is washed several months to reduce salt and impurity content. This provides a low EC environment suitable for tender seeds and young roots. Cubes have a neutral pH and should be soaked in water with a pH range of 5.5 to 5.8 for at least 3 hours prior to use. This plant-starting medium allows the release of 60%-90% of the water even when squeezed, yet is firm enough to support the weight of breaks. Socialize over watering, they drain freely!

The Washed coir gets rid of the risk of chemical resdue or contamination that you’d get with soil based starters as well as the inconsistency of those products from batch to batch.

Superior Moisture and Air Regulation

Thanks to its fibrous structure, Grow Cubes have optimal water-retaining qualities; oxygen can easily permeate inside growing very well. This mix is important for good germination and good root growth, because it allows to avoid to much watering as well as it prevents the roots from suffocating. It always stays moist and never waterlogged, so seeds have the water and air they need until roots develop.

Whether you’re growing in high humidity, high moisture packaging conditions, or you’re known for your strong and luxurious foliage, make sure your seedlings get started off right with 1.5” biodegradable coco coir seedling cubes.

Flexible Growing Applications

The Grow Cubes have many different uses:

• Vegetable seed propagation
• Flower and herb sprouting
• Hydroponic transplanting
• Greenhouse germination trays
• Nursery starter kits

Their modular design accommodates most common trays or plug systems and do not require added soil or media! This renders them perfect for those growers seeking simplicity, cleanliness and mobility when it comes to their sowing activities.

Environmentally Friendly Without Soil

One of the biggest benefits of the Grow Cubes is that they are environmentally friendly and dirt free. These cubes are 100% natural coir fiber, and they biodegrade fully over time and can be transplanted directly into the ground or larger containers. They help make eco-cultivation sustainable by minimizing the use of plastic inserts and synthetic growing plugs.

And they are free of contaminants and chemical binders, helping to promote organic gardening principles. Their neat performance and low mess making them an asset in indoor spaces counting on accuracy and hygiene.
