It is also easily renewable, unlike peat moss. Coco coir, derived from the coconut hull, is made from the fibrous material between the outer husk and the actual coconut. Originally, coir was used for making cordage and ropes in ancient India.

It has also been used for making mats and other flooring materials. In the s, it was first used commercially in Holland to grow roses and lilies. Because coir worked so well to promote root growth, growers started using it for hydroponic gardening in place of peat moss. Coco coir is an ideal grow medium because it holds water exceptionally well while still promoting good drainage and aeration. It is also easily renewable, unlike peat mosswhich has been the subject of controversy for some time now because it is considered a non-renewable resource.

An average coconut tree produces coconuts a year, so there is a continual supply of a product that would otherwise be considered waste. Peat bogs, on the other hand, seem to be disappearing at a faster rate than they can be reasonable renewed. Some say that peat bogs take as long as 25 years to renew, while coco coir is constantly being made. Coconut fiber provides good aeration for plants and also retains water wellwhich are just a couple reasons coco coir has become a favored grow medium.

The pH of coir is also a huge benefit—while peat moss is considered acidic with a pH of 3.

This means coco coir is ready to use for most plants without adding lime. Nutritionally, coco is also an excellent choice.

Depending on the source, it is rich in potassiumironmanganese, copper and zinc.

If you are growing hydroponicallythis needs to be taken into consideration so you can provide the correct balance of nutrients. Coir has a high cation exchange rate that allows it to store nutrients and release them as needed. On the flip side, coir tends to hold on to calcium and magnesiumso you may need to adjust your nutrient mix accordingly.

Coir promotes the growth of beneficial bacteria because of compounds called lignins. Not only will beneficial bacteria thrive when lignins are present, helping to minimize harmful bacteria, but if you add beneficial microbes to your hydroponic systemthey will be optimized.

This means better growth, higher yields and less disease. Coconuts are essentially giant seeds, and as such, the coir fibers are rich in hormones and bio-stimulants that encourage plant growth.Growing weed in coco coir is a great way to to produce high quality marijuana for new and experienced growers alike. This list includes the coco coir medium and containers, amendments to improve aeration and drainage, and supplemental materials used in the growing process.

More experienced coco growers may invest in additional nice-to-haves like automatic watering timers and drip systems to reduce the amount of day-to-day work to maintain your plants. Make no mistake, growing weed takes a lot of effort. Suitable containers for growing plants in coco coir include fabric pots, air pots, plastic pots, or plastic grow bags. Fabric containers make great coco pots because they allow oxygen to more easily reach the root zone.

Transplanting multiple times into larger containers helps ensure a nice root spread. For most indoor growers 3 gallon or 5 gallon pots are a good size.

Plan to allow 1 week of vegetation time per gallon to ensure your roots fully grow out in the container. For large plants with very long veg times, 7 or 10 gallon coco pots are needed.

Growing Weed in Coco Coir

Outdoor growers should buy the huge bags, which accommodate the larger root system that comes with many months in the vegetation stage. You can realistically grow marijuana plants in coco coir pots of any material, even using 5 gallon Home Depot buckets with a few holes drilled in the bottom for drainage.

There are two different forms of coco that are commercially available: coco coir bricks and bagged coco coir. The main difference is that bagged coco is typically already buffered, hydrated, and ready to use right out of the bag.

Coco coir bricks are generally compressed, dried out, unwashed, and potentially unbuffered. Canna coco bricks or another high quality coco brick are your best bet — avoid the cheapest ones that you can find online. Coco coir pith is naturally high in sodium and potassium. Because of this commercially available coir is treated by soaking in a calcium buffering solution. This helps leach out any salts. Because coco coir is naturally rich in potassium, this can lead to magnesium and calcium deficiencies when it is used as a media to grow marijuana plants.

Learn how to use Cal-mag for growing weed in coco coir. Coco fiber holds a lot of nutrient solution, so it tends to be to damp by itself. To properly prepare coco coir for weed plants you need to increase aeration with amendments such as perlite or vermiculite. This allows it to dry out nicely in between waterings to encourage strong root growth.

Adding 2 inches of clean gravel to the bottom of your fabric pot or other container will allow for drainage. Bagged gravel can be purchased inexpensively at Home Depot or other garden supply stores. Make sure to rinse bagged gravel several times before using until the water runs clear. The best coco coir nutrients for growing weed are designed for growing weed in coco fiber.

Realistically you use any hydroponic nutrient line in coco, but some work better than others. Most coco coir nutrients for growing marijuana are salt-based coco fertilizer which allows the inputs to be immediately available, and there are some organic or veganic options for cannabis available as well. Canna Coco nutrients are a proven method for growing marijuana in coco and consistently yields good results.

You can get the best prices on Canna nutrients by ordering from Amazon, and some local hydro shops near me will match whatever the current lowest Amazon price is which is cool. General Hydroponics nutrient trio is a 3-part nutrient line that is suitable for growing weed in coco coir.

They come in some combo packs. Grow Big is used in the vegetative growth stage, replaced by Tiger Bloom once you see the first signs of bud development, generally a week or two after flipping lights to Big Bloom is used throughout both growing cycles. As always, invest in a cal-mag supplement as well.Whilst growing plants in coco coir is similar to growing in soilthere are some differences. This article looks at how you should be watering and feeding your plants when using the ecologically sound growing medium that is coco peat.

Our experts can guide you on how and when to feed and water coco coir, in order to give yourself the best chance of achieving optimum results. A good rule of thumb would be to water every four or five days. You also need to use a pot that provides good drainage, as your coco coir requires air as well as moisture to promote healthy plant growth. Achieving the ideal level of moisture in the soil will result in your coir letting out a little moisture — but it should disappear quickly through your fingers and then stop.

The weight of your plant pot will also provide a reliable indication of the amount of water being retained: the heavier it is, the more moisture it contains.

Another important factor to consider is the quality of the coco coir you are purchasing. For too long, peat moss has been widely used in domestic gardening. Being a plant-growing medium that takes hundreds of years to replenish, harvesting it for this use is simply not sustainable. Thanks for the good informations. They were growing way faster as in normal soil,i use coco fertilizers. I had them in 2l pots first after weeks they got pretty big and the roots became rootbound and i noticed some lower leafs dry out and at that time the plants needed 2 times per day water because the leafs dried out quicker if i only watered one time per day so i think they had not enough moisture and started to wilt.

I started the flowering stage and the plants exploded in size. They are now around 1meter in height but i started to notice that the leafs start to dry out again.

It looks like before where they were in the 2l pots and started to dry out too fast. But i thought if its too dry the plants start to droop and also if they are overwatered. They never had any droopy leafs in coco since i started the seeds in it. I took a look at the roots and the pots are fully rooted and thought maybe its a rootbound problem and found on the internet that rootbound can lead to different symptoms like leaf wilt.

Could rootbound be the problem with the dying leafs? I never had those problems in soil but my plants in soil never had such a root mass like in coco. From using leftover coffee beans to preventing dirt from getting underneath fingernails, master gardener Paul James shares his top 14 tips and shortcuts to make spring gardening a breeze.Coco coir is an increasingly popular type of hydroponic growing medium — and for good reason.

Listen to this post on the Epic Gardening Podcast. Subscribe to the Epic Gardening Podcast on iTunes. In the past, when coconuts were harvested for their delicious meat and juice, the coconut husk was considered a waste product. All of the material from the husk to the inner shell of the coconut was a discard product…until people realized it had many applications in gardening and home products.

Everything in between the shell and the outer coating of the coconut seed is considered coco coir. There are two types of fibers that make up coir — brown and white. Brown coir comes from mature, ripe coconuts and is a lot stronger, but less flexible.

White fibers come from pre-ripe coconuts and are far more flexible, but much less strong. To get coconut coir ready for hydroponic and gardening uses, it needs to go through extensive processing. First, they need to remove the coir from the coconuts. This is done by soaking the husks in water to loosen and soften them.

This is either done in tidal waters or freshwater. If done in tidal waters, the coconut coir will take up a large amount of salt, which will need to be flushed out by the manufacturer at a later stage. After the drying process, which is quite extensive, the coir is organized into bales.

There are amazing benefits to using coconut coir in your garden. But just like any other kind of growing media, there are also some downsides to consider before you buy. Good transition from soil gardening — growing in coco coir feels like growing in soil, because the two media look so similar. You can have a completely hydroponic garden that looks almost the same as a soil garden. Retains moisture and provides a good environment — coco coir is one of the most effective growing media for water retention out there.

It can absorb up to 10x its weight in water, meaning the roots of your plants will never get dehydrated. It can be used more than once unlike peat moss, which breaks down over time. Insect-neutral — most garden pests do not enjoy settling in coconut coir, making it yet another line of defense in your integrated pest management system for your garden.

You can practice the basics of hydroponic gardening without having to buy or build a hydroponic system and perform all of the maintenance that it requires. Inert — coconut coir is inert, meaning that it has no nutrients within it.

It may look like soil, but it is not soil. This means you will need to add hydroponic nutrients and control the pH when using coco coir. Needs rehydration — most coco coir products are shipped in dry, compressed bricks. Together, they provide a powerful growing medium.

How often should you feed and water coco coir in your garden?

Apart, they have very specific benefits. Choosing a coconut coir manufacturer that ages properly is thus crucial for good growing. Coconut fiber adds air pockets into your medium. Coconut fibers do break down rather quickly though, meaning the air pockets they create will also decrease over time.

Coconut chips are basically an natural type of expanded clay pellet. They are best thought of as a hybrid between coco peat and coco fiber. When using coconut coir in the garden, it is vital that you use the right mixture of these three types for the best results.

The most important factors in high quality coco coir is how it is harvested, prepared, and processed. Because none of these factors are directly in your control, you have to pick suppliers that follow all of the best practices for coco coir production.How should you water cannabis in coco?

This is one of the most frequent questions that we get. We argue that high-frequency fertigation is the best way to water coco. But, how much, how frequently, and what do you pay attention to? This coco watering guide answers all your questions about high frequency fertigation and how to water cannabis in coco.

I provide specific advice about how much water for each event and discuss how to determine your coco coir watering frequency. I include a coco coir watering schedule to help you set the timing of multiple daily fertigation events.

Be sure to read the complete series! When we water plants in coco, the water should always include nutrients. The technical term for this is fertigation, which simply means combining fertilizers with the irrigation water. Proper fertigation strategy is the key to getting the best results from your coco grow. In this guide, I explain how to put these principles into action. The feed chart determines the ratio, and EC determines the dose.

See our guide, " How to Mix Nutrients for Cannabis ". Principle 3: Keep the Coco Wet: Do not let your coco get dry! One of the key benefits to growing in coco is that it enables high frequency fertigation.

This article discusses just how frequently it should be. Principle 4: Run-off is Critical : Run-off carries away the excess salts and allows you to maintain a consistent root zone EC. Proper run-off practices are discussed below. Principle 5: Manage Electrical Conductivity EC : You need to monitor the EC of the nutrient solution you are adding inflow and the EC of the water that drains through and ends up in the saucer of each plant run-off.

As explained below, fertigation frequency is one of the main ways that you maintain that difference in the acceptable range.

This coco watering guide explains in detail how to put the principles of high frequency fertigation into action. It explains:. Many growers are concerned about watering because of their experience with soil. Happily, coco is not soil and it is a lot easier to know how and when to water in coco than in other media. There are a few basic rules for watering the plants and they can be mastered quickly.

Every time you water cannabis in coco, you should saturate the entire volume of the media. Remember that even at the seedling stage there is no real risk of over-watering. Properly conditioned coco retains adequate oxygen for the roots even when it is saturated.

Saturation is important to prevent salt build-up in the media which can burn your plant. The water that moves through the media and ends up as run-off is the mechanism that prevents salt build up. If the media is not saturated, then there is no water moving through it and salts accumulate.Coco coir makes an excellent planting medium for hydroponic gardens due to its excellent moisture holding ability and inert characteristics. Coconut coir is produced from the brown husk that surrounds the coconut shell.

It is composed of millions of tiny micro-sponges, which absorb and hold up to eight times their weight in water. It is a sturdy substance, lasting three times as long as peat moss. Coco is a great addition to the hydroponics arsenal! This is just one brick reconstituted with a gallon of water. Coconut coir is also called Palm peat, coco, or just coir. Some brand names are: Ultrapeat, Cocopeat, and Coco-tek. Coco-Tek Organic Coir Bricks.

You can mix coconut coir with perlite to improve drainage, or put a layer of perlite on the bottom of the growing bed before adding the coconut medium. A super all-around potting mix for your hydroponic garden. Coco-Coir is good for: drip systems, dutch buckets and auto pots. Not as good for ebb and flow, as it can be washed away. Works great.

Leave me a comment in the box below.Many hydroponic and soil growers prefer coco coir for a variety of reasons, but you have to keep track of important details to maintain your grow. Details such as how the medium is made, its general properties, and what coco coir nutrients are needed to keep your crop healthy. Managing nutrients is particularly important when working with coir. Here are all the facts you need to know about this grow medium, plus how Advanced Nutrients makes it easy to manage pH and nutrient balance for your coco coir-grown plants.

What is coco coir and how is it produced? The basic types of coco coir The advantages and disadvantages for growing in this medium What coco coir nutrients are necessary for hearty growth. Coco coir is a byproduct of coconut fiber. It was first used in gardening in the West in the 19th century, but fell out of favor because the low-quality coco available at the time degraded when used for short-term growing. Toward the end of the 20th century, it was rediscovered as an organic, environmentally sustainable substrate when new production methods made it possible to create hardier product.

The tiny grains of coir are extracted from the coconut shell and pulverized into a packable growing substrate. Traditionally, coconut husks were immersed in water for six months or longer to decompose. Today, the retting process can be completed in a little over a week using modern mechanical techniques. Next, the coconut fiber is removed from the shells by steel combs, in a process known as defibering. In this dried, processed state, the coir is ready to sell and use. There are three basic types of processed coco coir: pith, fiber or chips.

Using a mixture of the different types has its benefits. Coco pithor peat, looks similar to peat moss but is a rich, brown color.

The density of this product means it retains water extremely well — so for this reason, you might not want to use just coco peat, because it could swamp the roots of your plants. By itself, the fiber is not very absorbent and will break down over time, which decreases how much air gets to the roots of your plants.

However, it is hardy enough for reuse. Coco chips are small chunks of coir that combine the best properties of the peat and fiber. Coco chips retain water well, but also allow for air pockets, too. Dried bricks are common — all you have to do is add water — but most coco in brick form tends to be of a lower unprocessed quality. Quick harvests and big yields: When used for drain-to-waste growing, coco coir gives excellent results.
