Coco coir for growing weed

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.

The Science of Coir

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.

I mentioned “science” above, and it turns out “science” is a key aspect of why coco coir is an ideal medium for growing cannabis as well as other crops. Some of the properties of coir that allow crops to thrive when grown in it include:

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.

What Is Coco Coir?

Coco coir has another beneficial aspect that is good for not just cannabis but also the planet. It’s a renewable product. Coir’s water-holding-and-water-draining characteristic allows it to be a great substitution for peat moss, which is not a quick-to-renew resource. Less peat being used means less mining, which means less damage to the sensitive and diminishing peat bogs of the northern hemisphere. We came across an article in the New York Times that explains the peat and climate change situation HERE.

First let the majority of the extra water drain out into the bucket, then place the liner in the tub or on the ground so it can continue to let water drain out slowly.

8.) Mix in perlite with hands

Recap: Do you have everything you need to make your coco coir mix? You’ll need the following items to complete the tutorial above.

2.) After seedling grows first set of “real” (serrated) leaves, water with nutrients at normal seedling strength , and add a regular dose of Cal-Mag (Calimagic). Keep giving water until you get about 20% runoff out the bottom of the solo cup. The first set of leaves are round, but the second set are serrated and pointy. Once you see those leaves, it’s time to water your seedling with nutrients.

Like nearly all cannabis nutrients, the included schedule is aggressive and can burn your plants if given with every watering. No matter what nutrient system you’re using with your coco coir, I recommend giving plain water every other watering to prevent nutrient buildup.

If you stick your hand in and there’s no more hard parts left, then you’ve waited long enough. The coco coir should feel soft all the way through the bucket. You can mix the slurry around with your hands to get it to break up faster if you’re in a hurry.
