Why Choose Coco Coir?

Coco coir fiber is a superior alternative to peat moss and traditional potting soils. Unlike peat, which is harvested from fragile bog ecosystems, coco coir is a renewable byproduct of coconut processing. The natural fiber structure provides optimal balance of water retention and drainage, creating ideal conditions for root growth.

How to Use

Step 1: Place one compressed brick in a bucket or container.

Step 2: Add approximately 1.2 gallons of lukewarm water.

Step 3: Allow 15-20 minutes for the brick to fully expand.

Step 4: Fluff the expanded coir and use immediately, or blend with other growing media.

Tip: Warm water speeds expansion. Rinse before use if desired to remove any excess salts.

Benefits for Plant Growth

  • Optimal Water-Air Balance: Retains moisture while preventing waterlogging
  • pH Neutral: Won't alter soil chemistry (pH 5.5-6.5)
  • Disease Prevention: Sterile medium reduces risk of soil-borne diseases
  • Root Development: Fibrous structure encourages strong, healthy root systems
  • Nutrient Retention: Holds nutrients for plant uptake
  • Reusable: Can be reused for multiple growing seasons with proper care

Sustainable & Eco-Friendly

Sourced from the coconut growing industry of Sri Lanka, coco coir is a completely natural, renewable resource. Unlike peat moss, which takes thousands of years to form, coconut fiber is a sustainable byproduct that would otherwise be discarded. The material is 100% biodegradable and can be composted after use.

With 24 bricks per case, you have enough growing medium for:

  • 48+ gallons of expanded coir (over 2 gallons per brick)
  • Multiple hanging baskets and containers
  • Entire season's worth of seed starting

  • Custom potting mix blends

Professional Quality

Trusted by commercial growers, nurseries, and hobbyists worldwide, coco coir provides consistent quality and performance. The compressed brick format makes storage and shipping economical while maintaining product freshness.

Blending Recommendations

Use coco coir straight or blend with:

  • Perlite or vermiculite for extra drainage
  • Compost for added nutrients
  • Worm castings for organic fertilization
  • Traditional potting soil to improve structure

This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
