How to Grow Cannabis in Coco Coir
Now you fill the rest of your fabric containers and possibly solo cups for seedlings.
You don’t need any other nutrients to grow marijuana; the Flora trio + Cal-Mag will give your cannabis plants what they need to flourish through the vegetative and flowering stages.
6.) Maintain flowering plants until they are ready to harvest. Care is basically the same as before, except during the flowering stage it becomes more important to control temperature and humidity than ever. Cannabis plants are much more finicky in the flowering stage, and it’s easy to trigger problems if you aren’t controlling your environment. Watch over plants closely, and make every effort to expose all bud sites to light and a breeze. You can still train plants by gently bending too-tall colas, but avoid any major training once the plant has started making buds.
Any quality cannabis nutrients made for hydroponics will work well for growing in coco coir as long as you also use a Cal-Mag supplement.
Continue to water plants with nutrients with 10-30% extra runoff. Continue to always adjust pH water to 5.5-6.5 before giving it to plants.
Although you can re-hydrate coco bricks at home, a pre-made mix takes out all the work! I highly recommend choosing a mix that contains both coco and perlite such as Mother Earth Coco Mix (70% coco / 30% perlite for growing cannabis. I’ve grown with Mother Earth at least a half dozen times and always get great results. Another pre-made coco mix I’ve tried that works great for growing marijuana is Roots Organics Coco Soilless Mix.
We at Organic Mechanics think our Cocodelphia coco coir product is one of the best on the market. Why? For one thing, we buy our coir from just one farm in India, so our variability in quality is essentially non-existent. That farm washes the coir several times and relies on the monsoons of Southeast Asia to accomplish this. Once we have received the coir, it’s washed again as we rehydrate the air-dried, compressed coir blocks. Essentially, Cocodelphia is triple washed.
Packed with nutrients and biostimulants. It’s a formerly living thing, so it comes packed with its own set of nutrients, such as potassium, iron, manganese and zinc, to name a few. Again, you should take this into account when considering what nutrients to apply. It also contains biostimulants, which act as growth enhancers and give whatever is planted in it a boost.

Neutral pH. Its pH is close to neutral (6), so coir can be used straightaway. Peat is acidic (as low as 3-4) and needs to be treated with lime before use. This neutrality is good because it allows the user to add the nutrient mix of their choosing.
The Science of Coir
Cocodelphia is also ready to go straight out of the bag. Add in some other beneficial amendments such as Biochar Blend or Worm Castings for a punch of nutrition. Or plant in the bag and save yourself the time of potting.
Our Cocodelphia is also continually tested for heavy metals, and each test result comes back clean. Don’t just take our word for it! Our customers have done their own testing and tell us it’s the cleanest heavy metal-free coir for cannabis production around. And for you professional cannabis growers out there, you know cannabis that fails a heavy metal test means a lost crop and lost profits.
Watch for salts. If there is a downside of coir it’s the fact that the product in its raw form contains salts. You, the end user buying coco coir products, don’t really need to worry too much about the salt level because it has been processed and washed extensively before you receive it. But if for some reason you’ve found some compressed blocks of raw coir, do know the salts need to be rinsed away or else it can harm your crops.
What Is Coco Coir?
High cation exchange rate. This allows nutrients to be stored and used as needed, except for calcium and magnesium, which coir tends to hold on to. Adjust your nutrients accordingly. A calcium and/or magnesium supplement is a must do when growing in coco coir.

The Benefits of Coco Coir
One of the biggest challenges with soil is that it may or may not have all the nutrition your plants need. Even more challenging is trying to supplement nutrients and balance pH levels without spiking their feedings.
Optimal Water Retention and Drainage
There are many advantages to using coco coir as a growing medium over soil or even coco pebbles.
