## Questions & Answers

**Q: veg.Plants in containers, ratio of earth,composite liq,&this coconut fiber,i have a large container garden?**
A: It all depends on where you live and the amount of rainfall you get.  I live in an area of very little rainfall, high heat, and sandy/clay soil.  Everything has to be in raised gardens so I use a lot of compost and the coir would be great but expensive.  I only use it in my Plumeria.  Good advice would be the theory of thirds.  I'm not sure what liquid you're referring to.  If it's fertilizer that third wouldn't be advisable.  I mix Osmocoat slow release in all my soils.

**Q: Is this safe for a reptile?**
A: If you mean to use it as some kind of bedding, it is simply pulverized coconut shells.  It will retain water better than dirt, but I think it would be safe as long as they don't have an aversion to coconut.

**Q: Can this be used for worm composting?**
A: Definitely. I've used coir for my worm bins for over a decade now. It controls moisture, adds grit for digestion, and fluffs up the bedding for aeration. You can use it alone or add in other bedding materials. I add bedding materials like shredded paper to stretch out the coir.

**Q: 4 bricks for a total of 9 gallons or does each brick give you 9 gallons a piece?**
A: I have only used 1 block,  but I'm thinking it's 9 gallons in total.  I have added the brick to worm castings and garden soil for my container garden.

### ⭐⭐⭐⭐⭐ Great product
*by B***U on December 8, 2025*

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
*by J***G on October 9, 2025*

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
*by P***P on February 5, 2023*

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? ;)
