Must have

This is a must have in your soil mixes for aroids and expensive plants.

Easy to Use, Hard to Find!

Reviewed in the United States 🇺🇸 on June 17, 2013

Verified Purchase

This is a must have for a terrarium or planters that do not have drainage. I have a 40 gallon aquarium that I converted to a tropical terrarium and I used the charcoal on top of pea gravel. I also use this for planting in non-traditional plant containers that do not have drainage. This stuff works great and keeps plants fresh even with the high humidity of the closed terrarium. I have not had mold or any of the other problems when using charcoal under the growing medium. This stuff is great but hard to find locally. I am glad I bought it and did not skip this step. I'm afraid I would have had to start over very soon without the charcoal layer under the soil.

+ Resealable Bag
+ Price
+ Small Pieces
+ Many Uses
+ No Mold/Fungus Problems Anymore
+ Terrarium Remains Fresh

- Dusty (I wear disposable gloves and grab it from the bag instead of pouring to create dust)

_Bottom Line_ Yes, I would recommend this to a friend. I actually made another order after seeing how this product keeps the soil fresh. I enjoy putting plants in containers that are not made for plants (no drainage mainly), and glass containers cannot have drainage hole added easily. I removed several plants from fish bowls, vases, etc. and placed the charcoal in the bottom and put the plant back in. So glad I did! You cannot go wrong here especially for the amount/price. 5 Stars

Peace of mind for roots to breathe

Reviewed in the United States 🇺🇸 on January 12, 2020

This is amazing! It has helped keep my succulents alive indoors as it snows outside all winter. They’ve survived and thrived as they grow and I’ve primed them and no water ever rots bc of this. I simply add 1 inch, as suggested on bag, at the base of a pot (hole or not), add my very own soil mix of perlite, sand, and soil and place my succulents. This is also the same charcoal I use for my indoor herb garden, and all types of plants to increase oxygen to roots. I love this! It keeps my mind at peace knowing there’s isn’t rotting water at the base of my pots.

Exactly what I needed to blend in with my soil mix. The pieces are not too big or small but just right.

many uses, good price

Reviewed in the United States 🇺🇸 on March 4, 2011

Verified Purchase

Like the first reviewer, I checked a couple of local outlets before finally ordering this from Amazon. I intended to use it not in soil but to filter water, not for drinking but for bathing and for plant use (both collected rain and city water). I take tub baths and had been looking into chlorine filters for the tub, most of them seeming overpriced. I folded about a cup or so into a bandana and tied it around the tub spout. It took a little adjusting to make sure most of the water ran through it but the usually overchlorinated city water was significantly less chlorinated and did not sting my eyes and nose as it normally does. If I used it for nothing else it would be a good bargain. Going to try making 2-3' hose sections with screen ends when the growing season starts, and using those as a filter, as well as a filter from the downspout to the rain barrels.

A good deal, although I do wish I could have found it in my usual shopping areas. I was surprised there wasn't any horticultural/aquaculture charcoal at the home warehouse store near us, especially considering they sell pond equipment.

Great size for indoor potting soil, but a bit expensive.

Reviewed in the United States 🇺🇸 on July 14, 2020

Verified Purchase

This is a great size for making your own soil mix. It’s chunky and not too small. I use it to make my own potting soil for indoor plants. My only complaint is that for the size of the bag it is still pricey, but compared to similar products it on par with price. I wish it came in a larger size for a better value!

Small bag. Not worth the money. Not happy

Reviewed in Canada 🇨🇦 on December 16, 2020

Verified Purchase

This bag is TINY! Almost the same size as a water bottle - and it isn't even very full. 1st photo is beside a water bottle for size reference. Second photo is just me showing how empty the bag is when I haven't even opened it yet. Im just crushing the top down to show how it is only 3/4 full. Save your money and buy elsewhere.

Great quality. I would buy this product again. A little on the expensive side but still reasonable. I had trouble resealing the bag after use so I put it into another bag that was easier to reseal.
