Coco Coir Discs (30mm 50-Pack) - Organic Coconut Coir Seed Starting Discs - Coconut Fiber Seedling Soil for House Plants, Potting Soil, & Indoor Plants - Organic Coco Coir for Plants & Potting Mix

I bought these because I've never used coco coir discs or blocks and wanted to try them out. They are smaller than I thought—just like some other reviews say—but the description isn't misleading or anything. I guess my brain just expected them to be bigger! But I would say it's still a really good value for less than $10. I popped these right into the pot and then watered them. Way less mess than a bag of potting mix, and fun to watch them expand!

I am in long-term care, so wanted something that wouldn't cause a huge mess if it fell off my table. I bought the 35 mm size, which are the perfect size for the plastic water cups the med nurses bring us. You just need a small amount of water for them to swell up. I am transplanting and making 'starts' from my Pothos plants. I will put 3-4 in separate cups, then add them all to my 4" pots for my starts. I've made so many starts to share with other residents here, and advised them I will transplant them into bigger pots for them once they grow a bit. I want to make sure they take care of them properly, before investing money into bigger pots and soil, for them. I also bought plant growth hormone to dip the roots in as I transplant them. These discs are rich in nutrients and so convenient to store until they are needed. I think they would be great for kids or others just learning to care for a plant. Pothos are hard to kill, so I highly recommend those, as well! I am about to order another batch of these, and will continue to buy them, as needed!

Kind of small for composting toilet use. Use bricks.

I needed 3-4 of them to fill a 12oz seed starting cup. not bad just plan accordingly.

I wanted to grow greens in my hydroponic system but I wasn’t about to plant each individual stalk in my normal approach. Then thought of these as I remembered seeing them before. Took a bit longer for the seed to root but it eventually did and I got spinach! Also growing kale and green onions this way.

Great product.. a little pricy but the plants love it!

Be aware how very small these are. Works great for very small pots

Like a lot of houseplant people, I’m growing aroids, ferns, begonias, and the like. Lots of plants that appreciate staying that sweet spot of lightly to more heavily moist but not actually wet. I also keep a steady supply of cat grass going, which I grow from seeds. I’ve used one other brand of coco coir puck before with great results, and I have to say these are not good.First of all, they’re hard to hydrate. They repel water and then once they do take up water, they never, ever want to let it go. I’ve had other coco coir pucks expand readily in a couple minutes to a really nicely moist, crumbly mixture. These take forever and I wound up having to poke at them and break them apart. The result is a soggy, heavy substrate, far from ideal for potting plants.Low points on presentation too, because they don’t tell you on the package how much water to add. And god forbid you add too much because, as mentioned, once they take up the water they really have a hard time letting it go again, even if you squeeze it out as much as you can before potting.The second thing is they retain too much moisture over time. Where other coir I’ve used will release water and stay at a nice level of not-too-wet and not-too-dry for days, I have had plant after plant potted up in this stuff show up as “wet” on my moisture meter for 1, 2, 3 days after watering. This is terrible for the roots and will bring on fungal infections and eventually root rot and the death of the plant.I don’t want to give the impression I’m using only these for my soil, far from it. I’m mixing this coir with Bonsai Jack gritty mix or perlite or pumice plus sometimes I add orchid bark, and occasionally charcoal and worm castings, depending on the plant’s needs. Usually, this works well, but even those amendments aren’t enough to offset the problems with this coir.Introducing this coco coir has been pretty much a disaster. My latest batch of cat grass didn’t germinate as successfully and immediately grew mold. I’m about to repot yet another houseplant that 24 hours after watering is still reading fully “wet” on my moisture meter. Ugh.If you spend good money on quality ingredients and then mix this in, it can be such a waste and very time-consuming. Not only is repotting twice in a week hard on the plant, sitting in wetness is hard on the plant, too. And then trying to salvage other quality soil mediums like the gritty mix, charcoal, etc., from the mixture is annoying.I was using another brand and it was great and I bought this to save a little money. I guess you get what you pay for, sometimes. I won’t even use this for seedlings after seeing the immediate mold growth on my cat grass seedlings. Live and learn and don’t buy this stuff.
