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.

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.

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.

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.

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!

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.

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.

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.

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!

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.

Never use raw rockwool! The pH is too high. Always soak rockwool before using it for the 1st time. Soak with water or a nutrient mixture with the pH adjusted to 5 and an EC of about 1.3. As well as correcting pH & EC, a pre-soak also ensures an even distribution of the nutrient solution throughout the slab.

Make sure the rockwool slabs are horizontal. If they are not truly horizontal the moisture will run to one end of the slab. This could mean that some plants become too dry and others too wet.

Don’t just measure the EC of the feed water and the drainage water regularly, remember to measure the EC of the substrate too.

You can easily distinguish between CANNA Classic A and B products because the A bottle contents is coloured and the B bottle contents is colourless.

If you are using CANNA RHIZOTONIC always add this to the feed water, test the pH and adjust pH as necessary.

CANNAZYM extends the life-span of Clay Pebbles and other growing mediums because it breaks down dead roots.
