Your plants will thank you for this!
This stuff is amazing 🤩 and a bargain, all at the same time. I needed to repot some root-bound sansevieria and a little Christmas cactus that has outgrown it's big box store pot. I'm sold! From here on out I will keep this on hand. First off, it literally swells to at least 5 times from it's original compressed size, and fairly quickly too. It only took 20 minutes at the most. Secondly, you literally can not over water using this medium. It seems to drain better than sand, but holds enough moisture for your green babies. I don't have any plant growth to document at this time, but I'm excited to see how they progress. Did I mention there is minimal smell. And the faint odor I do detect reminds me of wicker furniture when its new. And it seems pure. I did not see any regular dirt in the matrix. Now for my purposes I mixed one expanded cocoa core brick, with 2 large scoops of garden soil, and two spade sized scoops of worm casting (for organic fertilization). OMG 😱 this made for the most beautiful potting soil I've ever seen. I don't think I will ever buy that expensive potting soil again. This is waaaay better and all natural. I love it!

Perfect foundation for starting out a perfect grow
This was a pretty good value for the money for $16. I filled up three 5 gallon buckets of Coco. I’m not sure if you have looked at the price of a bag of pre-mixed coco but the cheapest bag I could find was about 30 some dollars and that’s barely enough to fill up one 5 gallon bucket so for 16 bucks I would say the size is amazing. Don’t be fooled by the size of the brick when you get it cause once you put water to it that thing’s gonna expand like crazy! It comes pre-washed in freshwater I like to buffer mine with cal mag and the plants absolutely love it. Their growth is exponential compared to dirt. there’s a lot of other cocos out there that have other fillers like wood chips and things like that this is 100% Coco husk ground down and compressed. I didn’t find any bugs. Any dirt just coco coir ..if you’re into the whole process of making your own medium for your plants and controlling your nutrients in a stable environment this is the way you wanna go I had a little bit of clay pebbles to mine just to help aeration and they work so well together.

Great quality product
I am really impressed with the quality of this product. While cheaper products can be found, when it comes to plants to don't wanna risk to loose, I like to stick to ones that I can trust for that. The bricks came well packed and like mentioned in other reviews, it is easy to store and takes no time to rehydrate it. it has even size particles, and I didn't find any foreign material. I usually hydrate a certain amount and store in a clean 10 gal bucket with a lid, to to be mixed later on with 1/4 potting mix, 1/4 perlite/vermiculite. I kept one bucket for almost 3 months, and even hydrated it didn't smell or rotted....really impressive. I have been more successful with my plants with this mix....really recommend it!

Really impressed with these coir bricks
These were great ! They expanded to at least 5 times the size easily and I was surprised with how much water they were able to soak up. I ordered a 5 pack, the bricks came very firmly pressed and didn’t flake much or lose shape at all during shipping. I like how they have a neutral + pleasant and earthy smell which isn’t very strong. I put all 5 in a 5 gallon Home Depot bucket and added water from my rain water collection containers, after filling the bucket up halfway I left the coir alone for a while and when I came back I found them needing even more water, it surprised me how thirsty these things were. When I was done adding water these things had expanded to fill the entire 5 gallon bucket and they had even expanded past the rim of the bucket. It’s really impressive how big these things get. I’ve already noticed an improvement in my potted plants and the coir is also great for cuttings and starting seeds. I also found the coir to pair really well with a generous ratio of perlite and a little bit of added potting soil for my succulent cuttings. The perlite breaks up the texture and let’s it dry out so the cuttings aren’t too moist.

Good value
Very good quality coir. I poured hot water on one of the brick and it expanded into a very large amount of coir. I mix it with perlite to make soiless mix for african violets. It looks like peat moss and is fluffy and foe not clump up. It is easy to use, just pour very warm water on it and it is ready to use

Much better than most other brands
Absolute best bang for your buck! Also this is great quality coco. I have used many brands off Amazon and this is now going to be the only one I purchase. Other brands can come soaked in salt water which is really bad for plants. I was having to wash my coco heavily before using until I switched to this brand. Also it has nice large pieces which is great for drainage. It also has a minimal odor compared to some brands that will arrive smelling like an industrial site. Overall I'm super happy. I use it for my indoor plants and also for my cacti I use 50/50 perlite and this coco with a little sand or volcano rocks for a topping.

I've bought better
I don't like this block as much as I like the coco bliss brand block of coir. It's still basically the same product. This one has a lot more stringy fiber in it and it did not Crumble up easily or well when soaked with water. I use coco coir to make seed starting soil for my garden plants. This brand remained pretty lumpy and i had to really sit there and break it up with a shovel then my hands and lots of water to get it apart and fine enough for mixing and potting. I wanted a cheaper block and that's what I got. My seeds still sprouted, I think they look a little less vigorous this year than in the past, but nothing some added fertilizer won't fix. So it does the job! Just not quite a nicely as i expected.

We buy this product to use in our composting toilet. It is very effective as a bulking product. We cut the bricks into smaller pieces and moisten them until they expand. The bricks are easy to store as well.

The quality was good 4 of out of 5. It had a good moisture retention and not lot of debris although it did had a little bit of a smell. However, make sure you have a big enough container I have a 21 l container and I had to soak the part that I was going to use and cut the rest

I was amazed how compacted this is!! Trick is to soak it for a while in wanter. If it isn't perfectly wet and absorbed, it'll be hard and messy to separate!! I used this in a soil mix. Very happy with the outcome and I will be buying again in the future.

So far impressed with product. Got almost a full wheel barrel full from that one brick. Was able to do 2 raised gardens and many pots with top mulch to help with drought. Hopefully helps with keeping moisture in garden. Used around 5-6 milk jugs of warm water to loosen up brick.

Compact size for the weight, easy to store and transport. I use a hammer and chisel to bust "flakes" off on the sides, then crumble those big bits up into the size I need. For my requirements this is much better than a big sack of loose material. Will buy again.
