Great product
This is the second time I’ve bought this product. I use it in all my gardening both in my flowerbeds and in my vegetable gardens. It works well and I’m very happy with it. We’ll buy it again next season when I till my soil

Works great for turtle hibernation
Great coco coir as expected. Purchased to create a safe and comfortable place for our turtle to hibernate over winter in our refrigerator.

Great For Seed Starting Mix
Rehydrated very quickly and easily. Mixed with (eyeball measurements) 8 parts coir, 1 part perlite, 1 part vermiculite. I used a butter knife to split off about half a brick and it separates well if you split it along the layers. That way you don't have to rehydrate an entire brick all at once. It's only been 24 hours since my little sprouts were transplanted, but so far so good! Will update if I notice any issues with plant growth. I think this will be a nice, economical, and more environmentally friendly way to start my seeds going forward. Only drawback - It doesn't smell like coconut. Wouldn't that be amazing? Coconut scented seed starting mix? ;)

Wow! Expands 8 times!
These will take a long time to use up for my houseplants. It is nice that they are in brick form.

Great stuff AFTER you rinse thoroughly
Been using this one pack for potting medium for about a year now and I still have one brick left. You really get a good value for how much it costs, but I would caution that you should really rinse it thoroughly to get all the potential salts out. You can tell these coconuts were probably farmed by salt water by how much sand come out of the husks when rinsed.

Excellent Soil for Lucky Bamboo
I needed a good amount of soil to transfer my lucky bamboo from water, and this product was perfect. It's easy to use, affordable, and compact for storage. I only used half a brick and still had some left over. Mixing in perlite worked great (remember to wear a mask when mixing).

Amazing
Simply amazing, I was doubtful about buying a compressed substrate but so glad i did. This has a very nice, clean, "dirt" smell, very fibrous, the coconut husk fibers look to be a very good medium for root growth, especially once I added some perlite to the mix. I think without something added this might compact down and slow or even prevent proper root growth. Once I added perlite it was nice and fluffy, I've only just planted my carrots, here's hoping it works as good as it looks. *a little late on the update but my carrots actually turned out great, I had a bit of a crowding issue so they were a bit small but that was on me, next season I just know they’ll be amazing. There is definitely a learning curve to bucket gardening, but I am still in love with this products performance and I will be purchasing more for sure!*
