Sukh Horticultural Charcoal for Plants - 1Qt. Natural Earth Regulated Supplement for Potting Soil Indoor Plants, Organic Biochar, Succulent Soil, Paphiopedilum, Bonsai, Terrarium

Perfect! Great value and high quality.

This worked perfectly for our Earth Day terrariums we made. It was enough to do 10.

Hard pebble sized pieces of charcoal for your plant needs. The plants in my aquarium have not died so I would say this works! Your hands will get dirty

The chunks are much larger than I expected, almost the size of bark, which is fine because I purchased this to add to my plant substrate. I was hoping to make a DIY semi hydro substrate (Pon) but I can add it as a soil amendment instead. I guess you get what you pay for. It comes vacuum sealed and VERY dusty. I rinsed & soaked a few times in a strainer. It fills a gallon size ziploc by about 1/3.. On a budget I would buy again.

Good quantity for my plants it’s a must

I am pleased with my purchase. The granule size is perfect for my horticultural needs, eliminating the need to crush or break them down. The hermetically sealed, sturdy plastic bag is likely for shipping, but the product can easily be transferred to a zip-lock bag if preferred. It came in the right amount I need. Being orchid and tropical plant growers, we know aeration and moisture retention are key, so you don't need a lot of charcoal in the potting mix. A quart will go a long way for me; you get the amount according to your potting needs. I see no dust in the bag, and I would say it's right on the money.

It is a bit pricey for what you get. But I ordered it twice so I knew what I was getting and can't really ding it for something I knew. I love it and the effect on my house plants was nearly immediate. I put full nuggets on the bottom for drainage. Then smaller pieces a mix in the soil, moderately, that I fully top the soil with a layer of the smallest pieces. It works great. One thing I haven't read is advice to water a little less as this charcoal absorbs water and releases it when surrounding soil gets dry. Instead of say, watering once a week, you can go to watering about every ten days or so. Plus when you have plants that need misting the topping layer of the charcoal will absorb some of the mist keeping the humidity factor up for a while. Not for nothing, the plants look really good with this as a topper.

The charcoal will work for my project. However, the picture are misleading on how much 1qt looks like and actually is. Picture attached.
