Coir pots are biodegradable pots made from coconut coir, a fibrous material extracted from the husk of the coconut. These pots have become increasingly popular among gardeners and farmers in recent years due to their many advantages over traditional plastic pots. 

In this blog, we will discuss some of the benefits of coir pots and explain why they are a best alternative to plastic pots.

Advantages of Using Coir Pots

Biodegradable & Eco-Friendly

One of the main advantages of coir pots is that they are 100% biodegradable. Unlike plastic pots that take hundreds of years to decompose, coir pots break down naturally over time. It means they do not contribute to plastic pollution and can be safely disposed of in compost bins or buried in the ground.

Promotes Root Growth

Coir pots are porous, meaning air and water can easily pass through them. It promotes healthy root growth as they are able to absorb nutrients and moisture very easily. The porous nature of these pots also means they prevent waterlogging, which can lead to root rot.

Durable

Despite being biodegradable, coir pots are surprisingly durable. They can withstand a wide range of temperatures and weather conditions, and they do not break or crack easily. This means that they can be reused multiple times before they need to be disposed of.

Light Weight and Versatile

Coir pots are lightweight and easy to work with. They come in a range of sizes and shapes, making them suitable for a wide range of plants and gardening applications. They can be used for seedlings, herbs, vegetables, and even trees. Coir pots are also compatible with most potting mixes, making them easy to use in any gardening or farming setting.

Reduced Transplant Shock

When you transplant a plant from one pot to another, it can experience a period of shock as it adjusts to its new environment. This shock can cause the plant to lose leaves or even die in some cases. However, with coir pots, the shock is minimized as they can be planted directly into the soil along with the plant, without disturbing the roots.

In summary, coir pots are an environmentally friendly and versatile alternative to traditional plastic pots. They offer a number of benefits, such as promoting root growth, and releasing nutrients into the soil, as well as their durability and biodegradability. Whether you are a gardener or a farmer, coconut pots are a sustainable and practical solution for all your potting needs.

Coir coins, also known as coir plugs or coir disks, are small disks made from coconut fiber, or coir. They are typically used for seed germination in hydroponic systems, as well as in traditional soil-based gardening. 

Coir coins are designed to hold moisture and provide a suitable environment for seed germination. They are often used in conjunction with seed trays or pots and are placed in a hydroponic system or soil to promote the growth of seedlings.

Advantages of Using Coir Coins

Eco-Frriendly

Coir or coco peat is a natural, renewable resource that is biodegradable, making it an environmentally friendly choice.

High Water Holding Capacity

Coir has good water-holding capacity, which makes it an ideal substrate for seed germination. It can hold up to eight times its weight in water, helping to keep seeds moist and providing a favorable environment for germination.

pH Neutral

A good quality coir is pH neutral, meaning it does not affect the pH of the water in the hydroponic system. This is important because the pH of the water can have a significant impact on the growth and development of plants.

Light Weight

Coir is lightweight and easy to work with, making it a convenient choice for use in hydroponic systems.

Overall, coir coins can be a useful tool for germination and plant growth in hydroponic systems due to their water-holding capacity, resistance to pests and diseases, pH neutrality, and other beneficial properties.

Also, different types of hydrotons that are available in the market.]]>
  • When it comes to growing crops, there are several popular (and some not so famous) grow mediums that can replace soil like Vermiculite, Perlite, Rockwool, Coco peat, Hydroton, Growstone, Floral foams, Sponges, Gravel, etc.
  • Each one of these has its pros and cons. No particular medium may be overall best, but depending on specific set-up, one medium may be superior to others. In this article, we will explain why we recommend using Coco Peat and Hydrotons for a home-based Kitchen Gardens.

Cocopeat Powder

Fly-Ash Hydrotons

What makes an ideal growing media?

  • Before we can identify the best medium for growing crops, it is imperative to understand what role does grow medium plays in the crop life cycle. Grow medium is the zone that houses the plant's roots. Any medium that can provide ideal conditions for root growth would be an excellent growing medium to replace soil. For perfect growth, plants need their roots to be in a zone that maintains slightly acidic pH (between 5.5 to 6.5), provides a sufficient amount of oxygen, does not result in inundation of roots, and neither allow them to dry out completely.
  • If you consider Coco Peat and Hydrotons, they appear right on most of these counts.

Cocopeat

Coco Peat is made out of dried coconut husk. It is pH neutral, which is ideal for plant growth and does not need pre-treatment before sowing, unlike various other grow mediums (including soil in some cases). It has a high water absorption capacity and also promotes root aeration as it retains a good amount of air even when wet. Further, Coco peat also has limited antifungal properties, which help in keeping pests away.

Clay Hydrotons

Expanded Clay Pellets (popularly known as 'Hydrotons', the brand under which they were first manufactured and sold by a German company named Okotau) are formed by expanding clay at very high temperatures. This process turns small clay pellets into large porous balls that boast of high water retention and drainage properties along with inherent features that allow for continuous oxygen exchange in the growing medium. Further, they are also pH neutral and can be sterilized and reused multiple times.

Fly-Ash Hydrotons

A cheaper alternative to leca is fly-ash pebbles, often mislabelled and sold as leca by various vendors. The difference between real clay based leca and fly-ash based hydrotons is that the latter is made out of fly-ash which is a by product of coal and cement industries. For mixing with cocopeat, even fly-ash hydrotons will provide most of the benefits that leca would.

Leca Hydrotons

City Greens pure Leca Clay Hydrotons are made from 100% clay with excellent wicking action, and are uniform in size with a height 20mm and diameter 17mm. Best clay media for improved aeration, these clay balls are strong, sturdy and retain their shape, allowing continuous oxygen near the root zone. This helps the plant to grow healthy. The hydrotons are pH neutral, highly stable in both varying pH & EC.


Though both are suitable mediums and can be used individually in specific set-ups (cocopeat in grow bags or kitchen garden and Hydrotons in Dutch Buckets or NFT systems). However, combining the two brings the best of both worlds for a kitchen gardener. Let us explain why.

Ideal growing media for Kitchen Garden

  • As pointed out earlier, an ideal growing medium should not only have good water retention capability but should also allow enough aeration in the root zone so that plants have good availability of oxygen in the root zone.
  • Cocopeat, though, has excellent water retention capabilities, it does not have good aeration capabilities. Also, with time the cocopeat compresses, further reducing the availability of oxygen in the root zone. That is one reason why you need to replace the cocopeat in your garden after every few crop cycles. 
  • Hydrotons, on the other hand, provides excellent aeration but dry out quickly. If you mix cocopeat with Hydrotons, then due to the presence of big size Hydrotons, the aeration quality of growing media improves. At the same time, the water holding capacity of cocopeat ensures a perfect balance of moisture and oxygen, which does wonders for the root growth. 
  • As such, if you mix 15% to 20% clay balls or fly ash balls or leca clay to the cocopeat, you will notice improved plant growth, and it will also increase the longevity of the growing media.

The blog also points out the preventive, and curative measures to avoid or remove algae.]]>

What is Algae?

Algae is a type of plant-like organism that can be found in water. It is often green in color, but can also be brown or red. It needs sunlight, water, and nutrients to grow.

Common Problems with Algae in Hydroponics.

Algae is a common problem in hydroponics systems, as the presence of light, water, and nutrients can create an ideal environment for algae growth. Algae can interfere with the growth and health of the plants by competing for light, water, and nutrients, and can also lead to reduced water quality and clogged irrigation systems.


Here are a few specific problems that algae can cause in hydroponics systems:

Nutrient competition

Algae can absorb nutrients from the nutrient solution, which can reduce the availability of nutrients for the plants. This can lead to nutrient deficiencies and reduced plant growth.

Oxygen 
depletion

Algae can consume oxygen from the water, which can lead to oxygen depletion in the system. This can be especially problematic for plants, as they require oxygen for proper growth and development

Water quality issues

It can contribute to the build-up of organic matter in water, which can lead to reduced water quality and increased bacterial growth. This can be harmful to the plants and can also lead to clogged irrigation systems.

Aesthetically unappealing

Algae can also make the hydroponics system look unappealing, which can be a problem for growers who are using the system for ornamental or decorative purposes.

How to Avoid Algae in Hydroponics?

Prevention is Better Than Cure!

As discussed earlier, algae needs sunlight, water and nutrients to grow. Avoiding sunlight can greatly reduce the formation of algae in hydroponic systems. Keeping the tanks in shade or using black tanks, covering empty grow spaces can help in preventing algae formation. At City Greens we have "2 inch Black Net-pot Covers" that can be used to cover any empty grow space created after harvesting or removing any diseased plant.

Using Hydrogen Peroxide

H2O2 is a chemical that can help kill off algae and other aquatic organisms, making it a useful tool for controlling algae growth in hydroponics systems. It is generally recommended to use a 3% concentration of H2O2, which can be added to the nutrient solution or sprayed directly onto the algae. Using H2O2 in large quantities can also be toxic to plants. Therefore, to is important to use in recommended quantities and follow manufacturer's instructions.

In addition to above methods, there are other measures that can be taken to reduce algae growth in hydroponics systems, such as increasing the circulation of the nutrient solution, and maintaining proper pH and nutrient levels. By implementing these strategies, hydroponics growers can help prevent algae formation and promote healthy plant growth in their systems.
