Clean, High-Quality Coco Coir That Expands Into a Massive Amount of Growing Medium
I’ve used a lot of coconut coir products over the years, and this is one of the better ones I’ve purchased. The first thing I noticed is how clean it is. Many cheaper coco coir bricks seem like they were swept off the floor of a processing plant and contain sticks, chunks, fibers, or random debris you have to pick out by hand. This one was clean, consistent, and ready to use. The block itself is huge. I actually split mine in half with an axe and hydrate it in two separate batches because one full brick expands into an enormous amount of material. In my case, a half brick fills a wheelbarrow with fluffy hydrated coir after adding water and letting it sit for about an hour. This makes an outstanding base for homemade soil mixes. I combine it with composted manure, earthworm castings, mineral rock dust, quality potting soil like Fox Farm, and sometimes even inexpensive store-brand potting soil to create large quantities of rich growing medium at a very reasonable cost. The texture is light and fluffy and provides excellent aeration for roots. Plants seem to establish quickly in it, and it holds moisture well without becoming dense or muddy. I also appreciate that this coir appears to be properly washed and low in salts. Some cheaper coir products can cause problems because they weren’t processed well, but this one has performed beautifully for me. If you garden at any scale and like making your own soil blends for containers, raised beds, seed starting, or houseplants, this is an excellent product and a very good value for the amount you receive. ... show more

Wow!
Just wow! Can't believe how much it expands! I had to add 8 gallons of water per 10 lb brick. Soaked it all up and is doing great for my inside grow tent! Now I can have fresh veggies all year! I will definitely be getting more!

VERY CLEAN!
This is very very premium stuff, Very clean I really like the product,The only drawback is it comes in one block,If you want to use a small amount it isn’t easy, I tried to cut it and even saw it, It’s so compact and complicated, I’ll be more careful to notice such a thing in the future.

A customer for life!
Great coco and not dirty! Expanded like the packaged promised. Felt good in hand nothing sharp in this coco just fluffy and holds water. The 10lbs turned into triple its size after adding water. You can’t go wrong with the amount you get here and the weight of this coco.

Excellent potting soil alternative
Absolutely love the coconut soil especially for this drought Florida is having at the moment where natural moss and miracle-Gro just isn't cutting it You need something that's going to hold moisture and this really does it The texture is perfect The weight well it's 10 lb obviously The water absorption is naturally perfect The water retention is amazing I went to check on my grave that I bought this for and the plants there are surviving during this drought because of the health they have from the retention of the water very little dustiness ... show more

The Best!!!
I get this every month or two, the quality is the best of the three brands I've tried. Works great to mix with compost, perlite and vermiculite for excellent potting and raised bed soil. Also is great for as a rooting medium. Quickly expands when you add water,great lightweight texture.
