Choosing the Best Coco Coir for Your Plants
1. Coco Coir Bricks
Coco coir bricks, sometimes called briquettes or bales, contain dry compressed coir pith or coir chips. These bricks are extremely popular as they are very simple to use and economical (a little bit goes a long way).
All you have to do is break off the amount of coir fiber you need or use the whole brick, add water, and the brick will expand in size. You can then add the fiber to your plants as needed.
One of the other advantages of using coco coir bricks is their compact and lightweight size. If you have a larger garden, these bricks are better than carrying around a heavy bag of potting soil.
Some gardeners prefer bricks that contain coir chips like the Plantonix Coco Bliss Premium Coconut Chips Block/Brick as the chips are much easier to break apart than tightly compressed fibers.
2. Coco Coir Potting Soil
Coco coir potting soil like the FoxFarm FX14100 Coco Loco Potting Soil is a great choice for any gardener.
The potting soil contains coconut husk fiber and other nutrients like kelp, earthworm castings, and perlite. But you will have to add extra nutrients like calcium or magnesium depending on the type of plants you own.
3. Coco Coir Pellets
Coconut pellets like the Mountain Valley Seed Company Compresse Coco Coir Fiber are a unique type of coco coir. Extra compact, pellets are perfect for people who have smaller potted plants and the pellets are easy to carry. As coco pellets contain less coco coir fiber, you may have to use a couple of them to get the right amount for your plants.
4. Smart Tips for Using Coco Coir
Before you add the coconut coir to your plants, you have to check that the fiber has been washed free of salt first otherwise you will have to rinse the fiber a few times.
You also have to check the pH-range of the coco coir. Most bricks or potting soil mixtures have a low or a neutral pH level of 5.8 to 6.8, while other products with a higher pH may not be ideal for some plant types.
Some compressed coconut coir products may not contain enough tightly compressed fibers to retain the right amount of heat for successful seed germination in a grow tent. Using a seed warming mat may help with this problem.
