Loose coco placed into growing pots or containers can be easily inspected for moisture level by checking the appearance of the top of the substrate or by feeling the moisture level of the coco just below the surface, this is more difficult in wrapped coco grow slabs. The coco slab only needs to be placed in position, slits cut in the plastic sleeve and water poured in – the coco expands and can be planted out with no further effort. The disadvantage of slabs is that they need a very level surface to sit on so that drainage is even and they don’t provide the depth of growing substrate that a planter bag or pot can for larger plants.

For an extraction test, a small sample of coco is taken from the growing media, (several samples should be taken and combined to give a representative sample). Then 100ml of these combined samples is measured out (coco should be damp but not overly saturated). The 100ml sample of coco is placed in a jar and 150ml of deionised (or RO) water is added and the mixture shaken 50 times. This is allowed to sit overnight to allow extraction of nutrient ions in to the water. The resulting mix is then re shaken and filtered to remove particles and the pH and EC can be measured.

Often, piles of coir dust were not left to decompose sufficiently and the resulting coco had a high nitrogen draw down index, this meant that under soilless cultivation, even with well balanced nutrients, nitrogen deficiencies in the early stages of growth were common.

Coco substrates also had a high cation exchange capacity and retained calcium, phosphate and iron meaning these became unavailable for plant uptake until the coco had been in use for some time and had fully `conditioned’. As a result many soilless growers initially experienced problems with coco they didn’t understand. Few growers understood the degree with which the coco media was affecting the composition of the nutrient solution in the root zone and the fact that the coco provided an almost ideal physical structure for plant growth was overlooked.

Tips and tricks when using coco

However while there are excellent brands of coco on the market, there are also still poor quality supplies still being sold as a growing medium and growers need to select and only use a reputable brand, preferably one which has an accompanying `coco nutrient’ formulation designed to work with the cation exchange properties of the product.

Coco fibre is also the term often used to refer to the general purpose grade of coco which is ideal for growing longer term crops under soilless cultivation. Worldwide coco is used for soilless crops such as tomatoes, peppers, cucumber, melons, aubergines, ornamentals, cut flowers and many others because the structure of the coco does not break down over the time frame these longer term crops are grown for. Thus high rates of root zone aeration and moisture retention are typical in both short and long term soilless crops and this results in high yields and good root health.

These days good quality coco has proven to be a superior growth substrate for a large number of different crops, with the advantage of being from a renewable and environmentally sound resource.

figure 3: The optimum physical structure of coco means that crops are provided with high levels of oxygenation and moisture in the root zone.

This means that nitrogen draw down is no longer a major problem, sodium contamination from retting in seawater does not occur, the naturally occurring potassium levels are adjusted and treatment with calcium and other ions is carried out before the product is packaged. Suppliers of high grade coco also carry out regular testing of their product to check for any irregularities in supply and to correct for these.

Water to 15-20% runoff to prevent nutrient salt buildup. Ph should be 5.8–6.0.

For coco grows you’ll need to supplement your nutrient solution with CalMag Plus or another Calcium and Magnesium supplement. Coco growers frequently run into Ca issues. Learn how to use CalMag plus.

Lighting continues for 18 hours per day during this stage. Once roots are established stronger lights such as Metal Halide can be used. Mother plants will stay on this feeding schedule continuously.

The Canna Coco additive bundle uses additives including Rhizotonic, Boost, and Cannazym.

Canna Coco A & B Feed Schedule

The Canna feeding chart is based on an 8-week flowering strain. The length of flowering for your specific strain may vary between 6-14 weeks. Most Indica hubrids for indoor growing are 8-9. You’ll need to modify your feed schedule a bit if you’re growing a longer-running strain.
