Takes more water to hydrate the coco coir than stated, but it is definitely worth the price.

I like to grow herbs in the quasi-hydroponic Click and Grow system, but the plants have a finite growth period in that system because plant food is stored in the growing medium and not delivered in the water. Transplanting is required for continued growth.I have been transplanting to standard potting soils like the MG brand. Every time I use potting soil, I am greeted by an infestation of annoying fungus gnats.Other indoor gardeners recommended a medium of coco coir + perlite, fed/watered with a nutrient solution. I had no experience with coir, and decided to try these pucks.These remind me a lot of desiccated sponge toys - when they get wet, they explode in size. These 80mm pucks do quickly expand to give a full liter of "soil." I love how the coir can be worked by hand, and not leave my fingernails dirty like potting soil with its manure/compost content. I created a medium of about 4:1 coir-to-perlite, placed it in my pots, and transplanted my herbs from Click and Grow.It has been about 6 weeks, and my herbs are thriving in the coir-based medium - it holds moisture extremely well, and I water them lightly about once a week with a dilute nutrient solution. Most importantly, I have not seen a fungus gnat!

I recently purchased the Minute Soil - Compressed Coco Coir Fiber Grow Medium in the 80 MM pucks (10 pack) to grow cat grass for my feline friend, Jo Jo, and I couldn’t be happier with my choice!The convenience of these compressed coco coir pucks is fantastic. Each puck expands tremendously when soaked in water, transforming into a rich, fluffy growing medium. I was amazed at how much each puck expanded—within moments, they turned into a generous amount of soil, ready for planting. It made the whole process super easy and hassle-free!Once I planted the cat grass seeds in the expanded coco coir, the growth was impressive. The medium allows for excellent drainage while retaining just the right amount of moisture, creating an ideal environment for the grass to thrive. Jo Jo took to the grass quickly, enjoying every bite of the fresh greens.I really appreciate that the coco coir is a sustainable growing medium, which is another plus. It’s perfect for anyone looking to grow plants or indulge their pets in a more environmentally friendly way. Overall, Minute Soil has definitely met my expectations, and I highly recommend these pucks to anyone interested in growing cat grass or other small plants. They are easy to use, effective, and provide great results!

This is excellent coco coir. It expands to an airy and light product that works great for both seed starting and bends for potted plants. The water runs through it quickly but remains full of moisture. What makes this particularly good coco coir is the expanded product is an especially fine grain, extra fluffy, and spongy (compared to other coco coir I’ve tried). I generally prefer coco coir over peat moss for both ecological reasons and the efficacy of coco coir over peat moss. This is particularly good coco coir and after using this product I don’t understand why people even bother with peat moss. Peat moss can easily dry into a solid bricklike substance whereas coco coir (especially this one) remains airy even if you accidentally under water. Since using this product there has been a noticeable improvement with my microgreen yield, my potted plants look happier, and the price point is reasonable. I’ve purchased this multiple times now and have been very satisfied every time.The only issue I have with it is it’s a rather large block and a bit of a commitment when you expand it to 15 gallons, but that is probably part of the reason it’s priced lower per volume than other products. To help avoid mold during storage I dry the expanded product in the oven on a low temperature (no hotter than 180 F). Higher temperatures release toxins into the soil like ammonium which are bad for plants so if you do this, keep the oven no hotter than 180 F. Then I combine it with 1 part vermiculite for 6 parts coco coir for an especially fluffy grow medium.

It's great soil for little projects, extremely cheap for how much soil you get. Have had a problem with mold growing yet, though I haven't had it set up for much more than a week.The only two downsides to this soil is that the coconut fibers are sometimes very long and also some questionable chunks. The soil also doesn't hold water incredibly well, but that wouldn't be an issue if you are able to water it once every day and there is enough soil/plant ratio
