If you would like to pursue this method of growing I would also suggest a few things I’ve come across when using it. Plants seem to really flourish when there is some perlite in the mixture because it adds even more aeration to the plants roots. Coco coir does a great job of this on its own due to its fiber like texture and plants love this mixture more than anything I’ve yet tried.
Another thing to keep in mind is that the plants will have to be watered much more often than a soil plant. Just like the oxygen flows right through the medium, so does water. It doesn’t hold water and nutrients that well so you will find yourself watering every other day. This can become a problem for the avid traveler because roots could dry up on them without a consistent watering cycle.
Even taking into the consideration the negatives involved in a coco coir grow, I find it a very effective method to grow high quality cannabis. Obviously there are far more determining factors than just the grow medium but I think it can be an advantage over a traditional soil grow or difficult hydro system. For beginners it’s ideal, you just have to know the best amount of nutrients to use in feeding.
This will all depend on what type of nutrients you choose as a grower. I stick with General Hydroponics but there are many different options that will vary in cost and results. Everybody grows differently and there is no doubt amazing weed that’s been grown organically in soil and in a complete hydro system, so choose what works for your environment and preference. I would highly recommend this grow medium though mostly due to the great aeration and direct grower control over nutrients in the plant.
