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.
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.
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!
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.
I'm using a re-circulating system. Should I use CANNA Classic or CANNA AQUA?
CANNA specially developed CANNA AQUA for recirculating systems. It contains all the nutrients the plants require in an available form. Remember to check EC and pH of the nutrient solution regularly.
CANNA Classic is designed for use in substrates such as rockwool and should be in a run-to-waste system. It also contains all the nutrients the plants require in an available form.
Soak rock wool before use
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.
Keep slabs horizontal
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.
Measuring EC
Don’t just measure the EC of the feed water and the drainage water regularly, remember to measure the EC of the substrate too.
CANNA Classic A and B
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.
RHIZOTONIC and pH
If you are using CANNA RHIZOTONIC always add this to the feed water, test the pH and adjust pH as necessary.
CANNAZYM and Clay Pebbles
CANNAZYM extends the life-span of Clay Pebbles and other growing mediums because it breaks down dead roots.
