THE BEST YOU WILL EVER BUY
Back to the roots is the best soul I have found yet and I have tried many. My plants never get overwatered in this sore for the drainage that it gives to my plants they never get overwatered again. I mix Burprer bone meal into it and it is also the best. I do a lot of cuttings off my coleus plants and never had roots grow so strong and beautifully. Between the perfect soil and the perfect fertilizer for my plants they are blooming so beautifully and fast. Never had this happen before my roots has never been so healthy my plants is never been so healthy it has been since I have switched to these two things. Very pleased I am and I am thinking about raising my flower bed with this soil but then they will never get overwatered either. You are not go wrong by using the soul or using the fertilizer I have said connect beautifully together. Wish I could give you a 10 star but there is only five but I still give you a 10.. Thank you for the best soil that makes my plants grow strong and beautiful.

Great Ingredient for DIY Soil Mixture
I’m always in search of the perfect soil blend that supports seed germination, seedlings, mature plants, and indoor and outdoor vegetables. The Back to the Roots expanding soil has become a key ingredient in my DIY mix. The directions suggest adding 7-10 gallons of water, but I use about half that. I place the 12x12x4 brick in a 21-gallon bucket and follow this process: • Pour on 2 quarts of water • Let it expand • Scrape off the slightly moistened soil • Sift • Repeat until the entire brick is sifted This method avoids over-saturating the soil, separates out fibrous coconut husk, and leaves behind rich, airy, fluffy soil. The sifted fiber is debris-free and works beautifully as top dressing mulch. I’ve noticed slightly lower germination rates when using pure coco coir, and some seedlings tend to die off around the 3” mark. To improve results, I mix my sifted coir with vermiculite, perlite, and a bit of horse manure. One of the photos show the original brick material, sifted soil, and fibrous husk - all from the same process. The other photo shows the soil blend in use, in a batch prepared from an earlier coco brick using my sift/blend method. The video clip captures the sifted soil texture as it sprinkles from my hand into the bucket. I appreciate that this product is odor-free, 100% organic, and upcycled. My plants respond well to it, and it’s become a reliable part of my soil-building process.

Earthworm 🪱 safe
I bought this expanding coir soil specifically to use as bedding for my vermicomposting bin, and it turned out to be a perfect choice. Once hydrated, the texture becomes soft, fluffy, and holds moisture evenly—exactly what earthworms need to breathe, move, and thrive. There are no additives or chemical smells, which gave me peace of mind knowing my worms were in a safe, organic environment. What I liked most is how clean and easy it is compared to typical dirt or peat-based mixes. It expands way more than you expect, so one block goes a long way. The worms burrowed into it immediately and started breaking it down, and I noticed activity and casting production increased within just a few days. It also controls odor naturally and keeps good airflow in the bin. If you’re into vermicomposting or setting up a worm farm, this is one of the best bedding bases you can start with—light, airy, and holds the perfect amount of moisture without getting muddy or compacted. Highlights: Expands a lot with just water (cost-effective) Ideal moisture retention and airflow for worm health 100% organic and safe for composting No mess, no odor — very beginner-friendly

Good Quality Potting Mix, But Be Mindful of Mushrooms
recently purchased this potting mix, and overall, I’m quite satisfied. The soil feels light, airy, and well-draining, which made planting very easy. My plants seem to be thriving so far, and the mix retains moisture without feeling too soggy. However, about a week after planting, I noticed some small mushrooms popping up in the pot. While it initially worried me, I learned that this is common with organic-rich soil mixes. The mushrooms are harmless and indicate the presence of healthy microorganisms. I just removed them and adjusted my watering routine to avoid overwatering. Pros: • Light, airy texture • Holds moisture well without becoming compact • Perfect for indoor and outdoor plants Cons: • Mushrooms may appear due to the organic material • Requires careful moisture management to avoid fungal growth

Excellent value for home worm bins
Works great in worm bins. I have been using a saw to break the brick down into smaller bricks and putting those cut down bricks in the bins but over the moisture barrier. It stays compact enough. Keeping it in the moist bin when I am ready to use it I can easily break off a hand full and and hand pulverize it. I have had no issues with moisture retention or excessive moisture. It helped me create a very stable bin. The value for my worm bin set up is excellent it has given me about a year before I needed to reorder. I personally would not use it as a soil but I would use it as an amendment. Having the excellent moisture retention it would help create an excellent potting soil mix. There is no dirt or soil it seems to be ph neutral. So definitely worth the reasonably low price.

Not too stringy, just nice ground up coco coir fibers!
This works perfect for growing microgreens! I still have these blocks I bought 2 years ago and they're still as dense as the day I got them. There's no weird smells. The texture is coarse, but there's some powder. There isn't a bunch of strings like some other cheaper ones. It's perfect for a growing medium. It really holds a lot of moisture so just be careful not to over water it or you'll get mold, which can be taken care of with a diluted spray of wither hydrogen peroxide or vinegar!
