Features

  • ECO-FRIENDLY & SUSTAINABLE - Coir is made of coarse fibers extracted from the husk on the outer shell of coconuts. It is a 100% natural by-product of harvesting coconut that used to be disposed until its benefits were discovered, thus making it both eco-friendly and sustainable.
  • SAFE & ORGANIC - Our Coconut Coir is 100% natural, organic and peat free. Coconuts are extremely abundant and do not need any fertilizers to grow. Our coconut coir has certified low EC, is triple washed and has the ideal pH (near neutral). It is biodegradable and has no chemicals or toxins that might affect its use negatively.
  • SOIL HYDRATION POWERHOUSE - Our premium quality compressed expandable potting soil is low maintenance and easy to use. It is one of the most effective growing media for water retention. It can absorb up to 6x its weight in water, so the roots of your plants will never get dehydrated.
  • OPTIMUM ENVIRONMENT FOR PLANTS - Coco Coir is sterile. It's a naturally clean substance without other stray organisms tainting its affectivity. It is considered to be an excellent seed starting medium. Always store in a cool dry place.
  • 100% SATISFACTION GUARANTEED - Our dehydrated coir brick weighs 10 lbs. Once hydrated and expanded, it has many uses from premium growing mediums for plants to fluffy absorbent beds for reptiles and animals or woodchip replacement for composting toilets. Use coir by itself or mix it with additives like perlite to make the perfect seed start mix with unmatched texture and superb water retention and aeration. You can also add compost, wood ash, limestone and more to make your own custom blend.

  • Sceptical, but now a believer!
Size: 10 LBS / 18-20 Gallons
I took a chance on this product and I like it! I have the huge pots growing vegetables and 2 raised beds I had to add soil to. While I'm not sure if there are any nutrients in this stuff, I added my own, mixing that and adding also to my compost. I let it soak in my wheelbarrow!! Made for lighter work to carry this around. ... show more

Why did you pick this product vs others?: Randomly picked this brick after being less than impressed by the last brand. The box says wait 2 hours, but within 10 minutes mine was almost fully expanded and ready to mix up

We use this in our reptile terrariums and hermit crab tanks. It absorbs water well and doesn't mold too much. We are repeat buyers!
