Growing cannabis in coco tips

Most insects and other pests that can damage your plants don’t like coco coir. Pests tend to land in soil because of the nutritional value they can obtain from it, but coco serves them no purpose, so they tend to stay away. In fact, other than fungus gnats, pests aren’t typically attracted to coco coir.

We’ve outlined the steps for preparing coco coir for your next growing cycle. It’s actually pretty simple.

Here are a few tips to keep in mind when watering your plants in a coco coir medium:

Eco-Friendly and Reusable

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 last thing you’ll want to know before you start feeding your plants is what you should be feeding them.

How Do I Use Coco Coir?

Coconut coir, or coco coir , is one of the most popular growing mediums for everything from ferns to cucumbers.

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.

Another important instrument is timing. Once the coco has become too wet, reduce or pause watering until the coco has dried out and then start normal watering again. Check the moisture content of the coco by hand or by determining its weight by lifting the pot or slab. A rule of thumb for watering fully-grown plants is 4 to 6 litres per m2 a day. By decreasing the dripping frequency and by increasing the amount of nutrients per watering, the best use is made of available water and nutrients. This will also improve drainage.

Apart from water, air is essential for the plant’s roots system. Research across various medium types show that more air leads to quicker and more intensive rooting, 6 to 10% higher yields and lower fertiliser use. Quicker and more intensive rooting means better root function in taking up water and nutrients, keeping up with the plants requirements. A way of achieving a higher air level in the substrate is to drip irrigate less often. More water is taken up from the substrate, the root system develops stronger, and moisture saturation occurs less often. The tests revealed that drip irrigating only once a day meant 3% more air was present in the substrate. You drip less with CANNA COCO.

Less growth due to water saturation

The frequency of watering depends on the evaporation and the water supply in the coco. A common rule is that one daily watering is sufficient during the first few weeks under normal circumstances; then increase up to 2 times a day; 2 hours after the lamps have been turned on and 2 hours before they are switched off again. Please keep in mind, smaller root volumes per plant (small pots or many plants per slab) will make coco dry out quickly. Therefore it is critical to water these plants more often.

CANNA’s COCO is made up of thousands of capillary micro-sponges that retain almost 1000 % of their own weight in water. Therefore coco retains an enormous buffer of water and nutrients. It is recommended that the grower keeps the medium a bit dry rather than soaking wet. Wet circumstances form an ideal basis for fungal diseases like Pythium. A drier substrate passes more air through to the roots stimulating them to absorb water and nutrients more actively. This results in a faster growth and higher yields.

COCO measuring method

A 1:1.5 analysis can preferably be done after 3 to 4 weeks. The target values for EC are between 1.1 and 1.3, for the pH, between 5.5 and 6.2. Very high EC values increase the risk of burning symptoms. To limit the risk of burning symptoms, the coco can be rinsed with acidified water (pH 5.8: acidify with CANNA pH – growth).
