What is Activated Charcoal?

Before tackling where to buy an activated charcoal powder, it’s good that we know what activated charcoal plants and the gardening for the same are.

Activated charcoal is a non-toxic type of charcoal formed when the wood is exposed to extremely high temperatures to make it highly porous.

Due to the subsequent high porous property, activated charcoal for terrariums is a sound-absorbent and an essential input in modern-day gardening.

The 2-Stage Process of Making Activated Charcoal

I will soon be answering where to buy activated charcoal stores but let’s first understand the process of making activated carbon.

The making of an activated charcoal terrarium can be summarized as a 2-stage process.

Stage 1: Carbonization – Carbonization is the act of taking any carbon-rich material such as coal, peat, or even organic carbonaceous material through a heating process, technically called pyrolysis, to convert it into pure carbon.

Usually, the activated charcoal for the terrarium is exposed to hot temperatures of between 600–1200 °C.

Stage 2: Oxidation – The next and last stage is oxidation.

During this process, carbonized charcoal is exposed to either steam or air with temperatures as high as 1200 °C.

The goal is to increase the charcoal’s surface so that it finally becomes porous and well aerated. This makes activated charcoal have a small surface with high adsorption qualities. Even though you can use a substitute for activated charcoal in potting or improve compost, you can hardly get the adsorption you get when you buy activated charcoal?

Benefits and Uses of Activated Carbon For Plants

Recently someone emailed us asking, “is charcoal ash good for plants?”

Well, what I can say is that when you buy activated carbon, you can put it into numerous uses in your yard.

It’s one of those underrated but potent farm essentials.

Let’s look at some of why you should buy activated charcoal powder.

  • Eliminate Molds – In the house, you can use it to remove molds around your home and other damp locations. Remember, Mold can be everywhere, and a moldy environment can cause numerous problems, including irritation, encouraging bacteria growth, and many more.
  • Water Retention – When mixed with soil, it improves its porousness and water retaining abilities. The soil will hold water for longer, saving you from constant watering. It also means your plants stay hydrated for longer, and this could be highly beneficial to plants that need a lot of water, like scarlet swamp hibiscus. You can also use it to filter water impurities.
  • Potting Plants – Charcoal for plants is MEANT to promote healthy potted plants. This is achieved by improved water retaining qualities of the soil and helps the fertilizer function more effectively. Again with higher moisture retention, potted plants will require less watering.
  • Removing Odors – It is also helpful in eliminating smells. If you have a fungal problem, you can call on activated carbon. It also does well in removing odors in your fridge or an area where your pet has lived.
  • Eliminating Soil Impurities – Activated charcoal adsorbs chemicals and toxins accumulate in the soil over time, posing a threat to your plant. Due to its good adsorbent properties, it draws the toxins out of your soil. Hence it’s becoming common to see gardeners mix it with soil when preparing for planting.
  • Health Benefits – Apart from its uses in farming, it also has many health benefits. Here are some of its health applications:
  • Reduce bloating and gas
  • Treat bile flow issues during pregnancy
  • Lowering cholesterol level.
  • Cure hangovers!
  • Treat poisoning cases and drug overdoses.
  • Treating acne
  • Getting rid of body odors.
  • As a first aid in relieving pain from insect bites, rashes, or even snake bites.
  • In case of inflammations from bites and contact from poisonous plants, some activated charcoal should help reduce the stress on the area.

So, as you can see, there are plenty of reasons you should ask, “where can I purchase activated charcoal?”

However, our discussion will revolve around activated charcoal for gardening for this post.

Activated Charcoal For A Terrarium

A terrarium full of moss and small plants that start as a delightful miniature forest can quickly deteriorate into one smelly, humid swamp just because you forgot activated charcoal.

So, even though you are often told to leave it out in multiple terrarium-making tutorials, activated carbon should be layered just beneath the soil in all closed-top terrariums.

Hence, even before deciding what to plant in a terrarium, find out where to purchase activated charcoal and purchase some.

This Is How It Works

A ½ inch layer of good-quality activated charcoal added under the soil & between asphagnum moss upper layer and gravel or pebbles on the lower layer acts as an excellent filter pulling toxins and all bacteria out of the soil/water.

It also deodorizes the terrarium.

Where to Buy Activated Charcoal For Plants (Terrariums)?

If you are really into boutique gardening, you will want to know where to buy activated charcoal for terrariums.

The good news is that most online stores like Amazon and Wal-Mart cater to artistic gardening and don’t add huge markups like the case with some of the specialty stores.

How To Choose Activated Charcoal For Your Gardening Needs?

Even as you ponder activated charcoal powder where to buy, let me highlight how to choose the correct activated charcoal for your lawn.

Know That The Applications Are Grouped Into 2 Categories

Applications broadly fall into water/fluid filter and air/vapor filter applications. Air/vapor filters mostly use the larger-sized granular Activated Charcoal (GAC), while water /liquid applications tend to use smaller GAC and powdered Activated Charcoal (PAC).

Particle Size

Sufficient contact time (with the activated charcoal) is crucial. The smaller your charcoal particles are, the faster the action will be.

But smaller particles may restrict the flow of nutrients and water. Therefore, try to strike a balance.

Molecular Size of Target Contaminant

What is the molecular size of your target contaminant?

There are three basic activated charcoal pore structures:

  • Micro (smallest) – usually below 20 Å
  • Meso (intermediate)–from 20 Å – 50 Å
  • Macro (most significant) – from 50 Å upwards

Match your target contaminant to the correct pore size.

For instance, activated charcoal made from coconut shells has a micropore structure- perfect for small air/gas molecules.

For wood-based charcoal, expect more mid-range pores.

Finally, coal-based activated carbon has larger macro-pores –perfect for larger color/protein molecules.

Frequently Asked Questions (FAQs)

The following are some of the questions frequently asked regarding activated charcoal for plants:

What Is Meant By Virgin, Reactivated and Regenerated Charcoal?

  • Virgin activated charcoal refers to the original product- never been used.
  • Reactivated charcoal is the activated charcoal that had already exhausted its lifespan but was re-exposed to steam activation.

This restores approximately 90% of the prior activity level, so it’s still safe and effective.

  • Regenerated carbon is an activity in which spent carbon is rinsed with either a chemical agent or water to remove some of the adsorbed contaminants.

Only around 5 – 50% of the initial activity level is restored.

Is There a Difference Between Coconut, Hardwood, Bamboo, or Coal?

Ignoring costs, each of these activated charcoal raw materials has unique qualities that make them fit some applications more than others.

Upon activation, each produces different internal pore structures hence accommodating molecules of various sizes. For instance, coconut-activated charcoal shines for air/vapor applications targeting odor control.

On the other hand, coal based activated charcoal is superb for color removal.

Is “Activated Charcoal” and “Activated Carbon” the Same Thing?

Sure yes. Activated charcoal is the lay term, while “Activated carbon” is common commonly in manufacturing circles.

How Long Does Activated Charcoal Last?

After knowing where to buy charcoal, learn how to store it, its life can be indefinite if you keep it in airtight containers.

Otherwise, if left open, in time, it will adsorb many pollutants and subsequently “fill up.”

Is it Safe?

Activated charcoal is, to a large extent, considered Safe. Some manufacturers go further to certify their products under agencies such as ANSI.
