Potting mix

Do you have problems with potting mix that becomes compressed and then absorbs water with difficulty? This can be easily overcome by mixing COCO with the potting mix, which will ensure that it can absorb water easily again.

Temperature & pH

To ensure good root development the feeding water must be between 20 - 25°C. When it's below 15°C the roots’ capacity to absorb decreases quickly, which results in a smaller harvest. If the feeding solution is mixed using cold water then the pH will rise when the water is heated. In this case, a high pH can be avoided by setting the pH a bit lower from the start.

CANNA potting mixes

The more nutrients that have been added to the potting mix in advance, the more difficult it will be for cuttings to take. This problem can be avoided by using CANNA potting mixes.

Keep your nutrients dark

Light breaks down iron chelates! Because of this, it is very important to ensure that no Ultra Violet light falls on the nutrient solution. Light also causes algae to grow in the nutrient solution, which can lead to blockages. Furthermore, algae can take up nutrient elements and cause nutrient deficiencies to occur.

Amounts of nutrients

Keep note of the amounts of nutrients and additives you add to each tank of nutrients you mix. You then have a good starting point for the next time!

Nutrient tank

Take your time diluting and adjusting your nutrient tank! This is essential for the growth, flowering and development of the plants and will yield the best results.

EC

Very high EC values increase the chance of burning, particularly for plants that are directly under the lamp. In order to reduce the risk of burning, the potting soil can be rinsed with CANNAZYM (pH 5.8 acidify with CANNA pH- Grow).

CANNA Terra Flores

Change from CANNA Terra Vega to CANNA Terra Flores when the flowers begin to develop. Normally speaking this will be after the plants have been lit for 12 hours per day, for between 1 and 3 weeks.

Adding acid to water

When you dilute an acidic product, always add the acid to the water, never add water to the acid, if it splashes it will cause burns on your skin or in your eyes!

Mixing nutrients

Measuring the nutrient reservoir works as follows: Take EC as the starting point, measure it and determine whether it should be higher or lower, based on the values shown in the instructions. Only then should you adjust the pH using pH- or pH+, if necessary. Try to get the nutrient solution’s pH value correct at the first attempt.

Adding CANNAZYM to your potting medium

CANNAZYM can be given continually and this is most easily achieved by mixing it with the feeding in the proportion of 2,5 ml/litre; 1:400, or it can be given once a week in the proportion of 10 ml/litre; 1:100. A further possibility is to add the CANNAZYM to the nutrient tank when it is just 25% full at 10 ml/litre; 1:100. CANNAZYM also makes the potting mix more suitable for reuse.

Adjusting pH

The products designed to adjust the pH are concentrated products. It is sometimes difficult to adjust the pH correctly in one go. To make life easier for yourself, dilute one part pH adjuster with ten parts water and use this to adjust the pH in your nutrient tank.

Don't use too much pH+ and pH-

Using too much pH+ & pH- with each other disturbs the bicarbonate concentration and the water’s buffering capacity. Also, the mutual balance between the different nutrient elements will be influenced and deficiencies could arise. Adding too much pH- or pH+ can be prevented by first diluting it with water before adding it to the solution.

Large plants

Do not place too many plants per square meter; plants will generally become larger on CANNA Coco and will need more space than on e.g. rockwool or potting soil.

COGr Boards

When cultivating in plant trays with a sealable drainage system, it is easier to begin by making the drainage incisions, then turning over the COGr and filling the plant container with the buffering solution.

Watering Coco

It's not necessary to water with CANNA Coco in advance of planting. It is recommen­ded to drip the coco with nutrient solution (2 ml CANNA Coco A & 2 ml Coco B /litre; pH 5.2-6.2) until drain appears. The coco now contains enough nutrients and water for a couple of days. Furthermore, the right temperature (20-25 °C) and high air humidity guarantee an optimal start.
