To help you out, here are the marijuana seed bank that work in any country.

Coco Coir is better for:

  • Control – you can control exactly what nutrients your plants receive
  • Fast growth and bigger plants
  • Drainage and aeration

Soil is better for:

  • Beginners – as nutrients are already present and it is a more forgiving growing medium
  • Time-saving – requires less attention
  • Organic gardening

What’s is the difference between Coco Coir and Soil?

What is coco coir? Let us explain.  As the name suggests, coco coir is made up of fibrous coconut husks and is a pretty recent discovery to the gardening world. It wasn’t until the 1980s that keen gardeners discovered that coco coir can be a perfect growing medium which promotes strong roots and vegetative growth. It can be either be added to soil or used on its own for hydroponic growing.
Soil as a growing medium you are likely to be more familiar with. This tried and tested method is popular amongst growers who like to produce their cannabis organically, in the most natural way possible. Soil can be used for indoor growing but is mainly used for outdoor cultivation. One key difference between soil and coco coir is that soil contains nutrients whereas coco coir is similar to an unfertilized soil and requires nutrients to be added to it.

What are the Pros and Cons of Coco Coir?

Coco coir is effectively a perfect neutral growing medium that you can customize so that your cannabis plants receive the optimum balance of nutrients and water. This gives you maximum control over what your plants receive, so if you get this right you will be looking at big yields and tasty harvests. Generally, plants grow larger and more quickly in coco coir than in soil.
Coco coir also has excellent drainage while at the same time being ultra absorbent – this means that your plants won’t be going thirsty – however, it does require more frequent watering than with soil. This medium is also known for its superb aeration qualities which supports the growth of strong and healthy roots. What’s more, this natural and renewable energy source will help your green credentials.
While easier than other hydroponic mediums, the major con of using coco coir is that getting the right nutrient solution can be tricky if you are new to the game. To give yourself a good start make sure you select nutrients that are specifically designed for use with coco coir.

What are the Pros and Cons of Soil?

In comparison to coco coir, soil already harbors many beneficial nutrients and microbes to nourish your plants and help them to fight disease. It is generally regarded as an easier growing medium than coco coir as you don’t need to become a nutrient expert to make sure your plants stay healthy, rather you just need to rely on mother nature herself.
Growing in soil is also less time consuming as coco coir as, in addition to not requiring a carefully balanced nutrient routine, your plants will require less watering. So if a low maintenance growing medium is what you are looking for, soil could be the option for you.
While you can add nutrients to soil, you will never have the same amount of control as with coco coir which is seen as a negative by some growers. However, for those of you that prefer a completely natural method of cannabis cultivation, the good old-fashioned soil medium may be just the ticket.
