Color: 51qt Compressed Seed Starting Mix
I used several bricks of coco coir to add organic matter to a 10x12sqft garden plot that was previously hard, compacted Arizona clay soil and sand. It works beautifully with our soil- coco coir soaks up moisture but releases it slowly, and by doing this, it also soaks up tons of excess minerals and locks them up, which I am confident will help prevent caliche buildup. Tilling the first few inches and mixing with a rough 1:1 coir-to-clay ratio, then covering with a top layer of a denser, 1:2 coir-to-clay mixture, resulted in firm beds that are a little spongy when compressed down by hand, which is exactly what I wanted for starting seeds in situ. This stuff is fantastic- it works exactly how you expect it to, and you can just drench it with your hose, so hot water is not required, it’s just slightly faster. I was able to hydrate a whole brick in about 20 minutes this way. It is an excellent soil amendment, especially if excess minerals or fertilizer are a concern. It also works somewhat as a mulch, and I regularly dust a thin layer on top of my plant beds to ensure their roots remain fully covered. I go through it extremely quickly whenever I need fresh soil, so if you have plans beyond a few pots, having one or two extra bricks will not hurt, and you can store it indefinitely until you need it. I will note here that using this alone will be sufficient for some plants, but you should have a source or clay, sand, or some other inorganic substrate to blend with coco coir most of the time. It is not prone to rotting quickly, but like any organic matter it will begin to decay once moist. In my experience (I’ve planted a few separate greenhouses and plots with it) it tends to pick up the odors already coming from your garden. This is probably because the coir becomes a host to the bacteria and fungi that are currently living around you, so keep that in mind if you’re concerned about odor- it actually smells kind of fresh and woody when first hydrated, but that will change after a few days or weeks once it’s been colonized by local bacteria and fungi. If the odor becomes a serious problem, it is likely you have a larger microbial issue with your garden, and it is not directly the coir, but it could potentially add to that problem. I would argue that, over time, it may improve your soil health, and by extension reduce unpleasant odors once a new microbial equilibrium is reached- but definitely test it in a small area or pot if you want to be sure. I have never had a major issue with odor that didn’t resolve itself after some amount of time, but allowing it to dry out will almost certainly be effective. Overall, it’s a low risk soil amendment, and I’ve never encountered any serious issues with it. If you’re new to gardening, it is extremely forgiving and easy to use, compact for storage, and can be used for pretty much any project. I’ve successfully used varying amounts in soil for tomatoes, herbs, plants native to the Sonoran desert, cacti, wildflowers, and roots.

I am very pleased with this coconut coir. I appreciate the size and weight of this block and how quickly it fluffed up in my wheelbarrow with some water. It has been helping me have great success with seedings and transplants into the garden. Purchasing many bags of quality potting soil was getting out of hand while filling my planters. I used a 3-part coconut coir, 2-part compost, 1/2 part perlite, and 1/2 part vermiculite mix, and am very impressed. There is a lightness to my potting soil, so it is not compacting down too tightly for things like potatoes. The coconut coir is fine enough to start seedlings, and I like its water retention. I am not having to water the mix with coconut coir as much as my other pots with store-brand potting soil. I do recommend that you fertilize about every other week since this mix is not soil. It is great for structure for roots and moisture retention, but isn't a long-term solution for vital nutrients. As a final comment, I highly recommend this product for seed starting, transplants, and improving your garden soil mix.

🌱 A Game-Changer for Gardeners! 🌱 ⭐️⭐️⭐️⭐️⭐️ I’ve been gardening for over a decade, and this expanding potting soil is easily one of the best products I’ve come across. Whether you're a seasoned plant parent or just getting started, this stuff is a must-have. First of all, the convenience is unbeatable. It comes in a compact, lightweight brick, but once you add water—wow! It expands like magic into rich, fluffy soil that’s perfect for potting, planting, or mixing into your garden beds. One small block gave me more than enough soil to repot multiple houseplants, start a few herbs indoors or an entire outdoor garden! The texture is fantastic—light, airy, and drains well, which my roots will definitely love. It’s made of natural coconut coir (bonus points for sustainability!), and I’ve noticed better moisture retention than with traditional potting mixes. That means less watering, healthier roots, and happier plants. No bugs, no bad smells, and definitely no mess—just clean, nutrient-ready soil right out of the package. It’s also great for indoor use because it’s dust-free and doesn’t compact over time. Bottom line: If you’re looking for high-quality soil that’s easy to store, use, and delivers results, this is it. I’ve already ordered two more bricks, and I’m recommending it to all my plant-loving friends!

First time I have ever used a product like this. It expands so much that I only used part of the block. I am trying it out in my container garden for tomatoes. It seems to work well but will update it once I start getting tomatoes.

Best soil I’ve used so far, everything grows! I have been experimenting with a variety of soils. This was easy to store and move around before opening. I have used it in ground, planters of all sizes and above ground planter all with one brick. I had a lot left over so I placed it around some of my established plants as well. I had seen some videos on how it expands and guess I didn’t realize how much soil there really was. I opened it and tried to tear off chunks to put in the above garden bed so I could water and expand but this wasn’t efficient 😂 That’s my own fault. I recommend using a large container like a tote as in some of the videos as it’s very compact. It was hard to tear pieces off. It was hard for me to know how much water to put in the chucks as well. That was my bad though. The soil drains very nicely the best I’ve seen. We have clay like soil and usually when I mix in other soils it’s hard as a rock after a few days this was not. This maintains its texture for a lengthy time. The color looks amazing. Highly recommend.
