If you’re working with limited space, have a hydroponic setup, or want to germinate seedlings that require precise handling, you need the best growth medium available. Coco grow cubes, made from coco coir fiber and pith, can provide you with a solid seedling bed that’s easily transferred to a pot or grow bag.
What is Coir?
If you’re new to sustainable gardening, you may not have heard of coir products before. Coir, in essence, is the fibrous part of a coconut husk. It comes in two varieties: brown coir, which is from mature coconuts, and white coir, which is harvested from pre-mature coconuts. Most coco coir grow cubes are made out of brown coir because it’s stronger and tends to retain more water.
Benefits of Coco Grow Cubes
Coco grow cubes are an excellent base for seedling root development. Because coir is highly water-retentive, absorbing up to 10 times its weight in water, coco grow cubes provide water retention that is unmatched in other growth mediums. And, because of coco grow cubes’ fibrous structure, roots will have a lot of growth medium to work through. This will ensure a strong root system for when you choose to transplant your seedlings.
In addition to being highly effective as a growth medium, coco grow cubes are exceptionally environmentally friendly. They’re highly sustainable because they’re made from the waste product of coconut production. Compared to traditional soil-filled grow bags, grow cubes are lightweight and are easier to ship and store.
Coco grow cubes are also non-toxic and highly resistant to mold, fungus, and bacteria. This is especially important because they provide an oxygen- and moisture-rich environment for your seedlings. More traditional non-soil growth mediums, like peat moss, can cultivate mold and potentially damage your plants.
Coco Grow Cubes: Considerations
While there aren’t many drawbacks of coco grow cubes, it’s important to remember that not every growth medium is perfect. Because coco grow cubes are an inert growing medium, you may need to add nutrients to them to make sure your plants will grow correctly. This is especially important if you’re using coco grow cubes in a hydroponic setup. If you intend to transplant your seedlings to soil or a mix of dirt and coir, you may not have to add any nutrient supplements.
It’s also important to get your coco grow cubes from a reputable supplier. If not processed correctly, grow cubes can contain a lot of salt or potential pathogens. A properly sourced cube will have been sterilized and dried correctly to avoid issues with salt content or contaminants. Make sure to ask your garden store or coco grow cube supplier how their coir is processed.
While there are a few considerations when it comes to using coco coir and coco grow cubes, the benefits are clear. If you’re new to gardening or hydroponics and are looking for a sustainable, eco-friendly medium to use for germinating seedlings, coco grow cubes are among the best options currently available.
