What Is Coco Coir?

You may already know what Coco Coir is, but this article is for you if you don't. Coco Coir is an organic product from coconuts. It includes anything from the shell to the outside of the coconut. This fibrous section of the fruit is not eaten, thus leaving a significant portion as a waste product. No more!

Coco Coir is a hidden gem for your gardens of all types. With a highly water-retentive property, this growing medium can absorb up to 10 times its weight in water. Not only can it add organic matter to your poor soils, but it can also prevent your plants from drooping and drying out. One of the only downsides to using this growing medium has been the lack of nutrients it can offer your mature plants. However, it is perfect for seed starts as well as microgreens as these stages of growth do not require nutrients from the soil.

Beyond this stage your seedlings will require additional nutrients making the standard un-amended Minute Soil Coco Coir an ill-fit for growing plants to maturity. To use the standard un-amended version for this purpose, additional fertilizers and nutrients are required creating much more preparatory work. This drawback has recently been overcome as a successfully amended coco coir is now available to you as Minute Soil+. This amended version includes the additional nutrients to support a season's worth of plant growth and development.

What Should You Use Coco Coir To Grow?

Minute Soil Coco Coir - Minute Soil is the perfectly light, but water retentive growing medium for seed starting and microgreen growing. Our mats, pellets, pucks, bricks, and blocks allowing you to add the amount of growing medium you need without having to store bulky amounts of soil that take time to use, and are heavy to move. For your seed starting needs simply add your compressed coco coir to your growing container and add water. You can watch it expand before your eyes with less work and mess than traditional soil growing.

Minute Soil+ Coco Coir - You can use Minute Soil+ amended coco coir bricks and blocks to grow pretty much anything you want! It has also been a popular choice for starting seeds that are going to be grown to maturity within your starting container or with the Minute Soil+ Cube. Minute Soil+ has been enhanced with all of the nutrients needed to feed your plants for an entire growing season with ease. No additional fertilizers or amendments are necessary for a good growing experience. Use in garden beds, potting indoor plants, and container or greenhouse growing. This amended version now allows for greater use in herb and vegetable gardens for a gardener of any experience level or ability.

Use our easy-to-follow instructions for a positive growing experience that won’t break your back. We assure you our compressed Minute Soil+ packaging is easier and lighter to handle than traditional soil preparation processes. If you are limited to gardening in small spaces, containers, or by what your body will physically allow you to lift, give coco coir a try. All you have to do is place it in your container, add water, and plant!

One of the best things about using Coco Coir is its origins as a renewable resource. This is not some new product being invented purely for monetary gain. It comes as a natural waste product that is now being recycled back into the earth for growth in healthy and happy plants.

Whether you want to try it out in your garden, containers, seed starts, or microgreen growing, you can find Coco Coir that is perfect for your use. It is available on our website in pellets, pucks, bricks, blocks, cubes, 10x10 or 10x20 hydroponic grow mats under the Minute Soil brand. All Coco Coir is unamended unless clearly labeled otherwise.

Great stuff. However, I’m trying to find out if Minute Soil + needs a micronutrient/mineral supplementation like Amozite? It really starts seeds far faster than soil. Thanks, Dennis


I love the info on miso paste. Definitely will look more into this

Coco coir was a great starter for my seeds indoors however I did not know or realize it would not sustain my tomato seedlings. I planted 5 variety, 150 seedlings and lost nearly half because at 5-6 weeks the roots began to stop growing in the coco coir. I learned thankfully that I needed to bear root them and plant inputting soil. Coco coir has a learning curve

Billie Martines

Coco Coir is my favorite to plant with! It holds moisture perfectly without molding! This allows me to water less and plant more! Love it. Thanks for all the other great info on it!


I have avoided coco coir in the past because I incorrectly thought it was the same as cocoa mulch. Coco coir is safe to use around pets, unlike cocoa mulch. I’m glad I read this post about all the benefits of using coco coir.

We use coco coir mixed with potting soil for starting seeds indoors but still use the peat when planting fruit trees because of the amount of the material needed to properly get the plant established – pick the right product for the job you are doing.
