Hoffman Charcoal Soil Conditioner - 24 Oz. - Improve Plant Growth & Soil Structure

Jessie IrvJessie Irv: 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.

Maria: 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.

feinbaby: keeps all my potted plants healthier, but ESPECIALLY the succulents i keep in jars and mugs without drainage holes. Succulents really need good drainage so pots without holes are a challenge, but THIS IS THE KEY! Not only does the charcoal at the bottom provide drainage (instead of, or in addition to, a layer of pebbles/rocks) but the charcoal keeps bacteria from rotting the roots and keeps mold from growing in the bottom, which is something that happens without fail to every single houseplant i'd ever had... until I learned about charcoal. And this charcoal is super chunky too, as opposed to the dust other brands sell, so it provides good drainage.

Ashley: I really liked the smaller chunks. Worked perfect for my terrarium and a couple no drainage pots. I also started mixing a little charcoal, to my soil. I usually mix my own soil. I think it adds extra air circulation for the roots. The chunks of charcoal aren't to small they are perfect. I had bought a bag from the local nursery and the chunks were really big or it was dust. Needless to say I really like this kind of charcoal. Perfect size and the plants love it. Just be careful when using the charcoal. It's all has a little dust and you don't want to be breathing it in. So I'd use a mask or pour it and back away for a few min. Hope this helps.

Carolyn F.: 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.

TS: It appears to be doing. I will have to see how my plants grow in time.

BG: 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...

anonymous in VA: 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.
