Versatile and High-Quality Coco Coir â Perfect for Plants and Worm Farms!
The Compressed Coco Coir 5 Pack is fantastic! I’ve been using it as a soil topper for my plants and as bedding for my worm farm, and both have shown noticeable improvements. My plants have been healthier, and my worms seem much more active. The coir is high-quality, easy to use, and has helped retain moisture while providing excellent aeration. Highly recommend this for anyone looking for a natural, effective way to enhance plant growth or create a thriving worm farm! ð±ðððððð

High-Quality Coco Coir for Seed Starting, with a Small Fiber Issue
I used these Vivlly coco coir bricks for sprouting radish seeds â I even attached a short video showing the process. Overall, the product performs really well: it expands quickly, absorbs water evenly, and creates a light, airy substrate that retains moisture without becoming soggy. The pH balance seems ideal, and my seeds started germinating very fast.The packaging is neat, and the product feels clean and natural, with no unpleasant smell or excess dust. Each brick produces a generous amount of soil â more than enough for several trays.However, there is one small issue worth mentioning: the texture is quite fibrous. As the seedlings start to grow, the intertwined fibers can cause the soil layer to lift slightly, forming a âmatâ that I had to break apart by hand and redistribute over the sprouts. Itâs not a dealbreaker, but something to be aware of if youâre using it for small seeds.In general, this is a high-quality organic substrate thatâs easy to work with, environmentally friendly, and very effective for seed starting, hydroponics, or home gardening projects.

Love it for my tarantulas
Had to write a review for this. Iâve kept tarantulas for around 15 years now, and use coconut fiber for their substrate. Itâs easy for them to dig through and holds moisture that is important for molts. I would usually buy zoo-med brand or whatever the pet store nearby carries. But this was a better deal and the reviews were pretty good. Well, they were right.I was able to rebuild two 10 gallon tanks and one 5 gallon tank with this 5 pack, and had to use the rest and 2 leftover bricks from another brand for the last tank. This brand is chopped in a way that leaves it consistent and fluffy. The pet store brand is stringy and chunky. This brand washed off easily. The brand bought from the pet store left my hands and arms itchy, as if the spiders had kicked hairs on me. This brand also seemed to absorb water faster and more consistently than the others. Iâm so pleased. Will be buying every time now.

So Far So Goodâ¦
So far, Iâm impressed.Unlike others out there, my bricks came in uniform size and weight. The brick was easy to use: just place in a bucket or pail and fill with water (quite a bit) and let soak for a couple hours or overnight. Once the brick has absorbed the liquid, it breaks apart easily.At first glance, the material seems to be of good consistency. Definitely retains moisture, as stated. Iâm pleased with the amount of expansion, and am optimistic that it will serve its purpose for starting my seeds. Only time will tellâ¦

I can not find proper words to say how bad product it is. All my flowers died . It took all the water and didn’t get any water to flowers. If you like your flowers, do not buy it.
