CANNA specially developed CANNA AQUA for recirculating systems. CANNA SUBSTRA should be used when using a run-to-waste system. Please do not mix those two up!

Two pumps can be used to supply the nutrient solution to the plants to ensure that they will not be left dry if one of the two should malfunction.

If there are any air pumps in the nutrient reservoir, remember that these may raise the pH in the nutrient reservoir.

Watch the roots closely. Otherwise they will grow into the drainage holes. This will block the drains and the system will stop circulating.

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 a record 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.

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!

Measuring the nutrient reservoir works as follows: Take EC/ppm 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 if necessary. Try to get the nutrient solution’s pH value correct at the first attempt.

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

Clay pebbles can have a high salt content. By rinsing the pebbles with water, these harmful salts can be washed away. An additional advantage of this is that dust particles are also rinsed off and these may have caused blockages.

We recommend to use PK 13/14 always for one week! CANNA feeding already contains a certain amount of P and K. When the plant is in a certain stage of the flowering stage we can't increase the feed for the plant any more, so we change the PK-ratio by adding PK 13/14 for one week.

Never dilute more CANNAZYM than will be used within 10 days.

If you are using CANNA RHIZOTONIC always add this to the feed water before you adjust the pH; CANNA RHIZOTONIC is a natural pH UP product.

Foliar feeding with RHIZOTONIC is most efficient when this is carried out around the time that the lights go out when cultivating inside, or just before sunset when cultivating outside.

Prevent the accumulation of phosphate and potassium by using PK 13/14 no more than one week.

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.
