I recommend larger containers for larger plants and to water less often. I recommend smaller containers for smaller plants, and when the grower is willing to water more often.
This stage lasts until your plant is about half the size you want it to be in the end. After your plant has grown half the desired size, it’s time for the next step.
4.) Fill the bucket halfway with water.
Coco coir holds onto a lot of moisture but also holds onto more air than similar materials, so your plant roots get the oxygen they need to thrive. When mixed with perlite, it provides an ideal amount of water and air for cannabis roots. Coco coir drains well so plants are less likely to get overwatered, but it also holds onto nutrients so you use less fertilizer.
Cons of Growing Cannabis in Coco Coir
Give Cal-Mag at full strength alongside your nutrients for at least two weeks at the beginning of your grow. You may also add Cal-Mag with your other other nutrients if needed throughout the grow, though you may want to give it at lower doses.
Which Nutrients for Coco Coir?
As long as you remember to water your plants with nutrients as directed, coco plants tend to be hardier than plants in other grow mediums. You typically won’t get bugs like in soil, or root rot like in hydro. It’s rare for a coco grower to run into major problems that prevent them from getting to harvest when they follow these directions. Because of that, I believe coco is one of the best grow mediums for new growers. Plus, you’ll learn almost all the skills you need to grow in soil or hydro in the future. Coco gives you a great base of knowledge for growing cannabis that will serve you well even if you branch out to other grow mediums.
6.) Pull liner up and out, letting water drain .
It’s worth noting that pests will always be attracted to your plants, so it’s always important to practice proper pest prevention and elimination. Still, coco deters more pests from landing on your plants because they know they can’t stay for long if they do.
Coco coir is one of the simplest growing mediums you can use for growing. Soil can be tricky to amend when nutrients and pH are off, and full-on hydroponics can be a little daunting for beginner growers. With coco coir, though, you can feed your plants all the nutrition they need without guessing what they’re already getting like you would have to with soil.
Like any growing medium, coco coir has its intricacies and requires that you know what you’re working with. By directly feeding your plants and retaining both water and nutrients, it’s a unique and effective growing medium.
How Do I Use Coco Coir?
If you decide to take the leap to hydroponic growing from soil, using coco coir is an easy way to make the transition from one to the other because you’ll already know how to feed your plants nutrient-rich water.
The best way to ensure you are providing your plants with the proper nutrients is to buy a fertilizer or nutrient set specifically made for growing with coco coir in potted plants or with a hydroponics system. General Hydroponics and Dyna Gro , for example, are great for coco coir grows because of the complete nutrition they’re able to provide.
The Benefits of Coco Coir
When you are able to properly fertigate your coco, you will achieve the best results with your plants. Here are the nutrients your plants will need if you use coco coir:
Unlike other growing mediums, coco coir is not a nutrient-rich solution. As such, you’ll need to use nutrient-enriched water or provide additional nutrients. This technique, also known as fertigation, consists of mixing nutrient-rich solutions and fertilizers with water.
