COCO & COGr substrates and nutrients

Because CANNA COCO is 100% organic it has a relatively high Cation-Exchange Capacity (CEC). This means the substrate has the ability to hold and retain certain nutrients vigorously thus requiring these nutrients to be supplied in a special form that remains available to the plant.

coco_content_1Due to the special coco charac­teristics in combination with the unique pre-buffering process, it is possible to combine vegetative and flowering nutrients in one nutrient mix. The medium and the plant itself control which nutrients are released to the plant at just the right times. This means the grower doesn’t have to worry about the proper point to convert from grow to bloom nutrients!

Why A&B?

CANNA COCO is a two-part nutrient; hence there is an A&B version. This is essential because the concentration and forms of the nutrients supplied interact with each other in the concentrated form. This interaction can cause non-recoverable preci­pitates and an overall change in those specialised coco forms of the nutrients.

CANNA Coco Plus vs. COGr

Let’s start by telling you that CANNA Coco Plus is far easier to use and is also available in 50 litre bags, this makes it possible to grow in pots. A second advantage of CANNA Coco Plus lies in the fact that it’s pre-buffered for you. Thirdly we developed a feed that is universal for the growth stage as well as the flowering stage. In other words: Easy to use, is the key word regarding coco.

cogr-slabs_content_1COGr on the other hand is only available in slab form. Perfectly fitting the trays used in the industry. They are not pre-buffered so don’t contain the moisture needed for successful buffering. Instead they are pressed, making it easy to set-up your grow space as they are light to carry. Earlier we mentioned the complete line of fertilisers for COGr, making it possible for the grower to precisely feed the plants. This makes COGr not as easy to use as CANNA COCO, but if used correctly it will bear its fruits in final yields. In other words: CANNA COGr is especially designed for experts!

A higher yield with COGr!

COGr consists of a specially formulated mixture of coco husks, coco fibre and coco granulate. This medium offers the advantage that it is aerated, therefore making it easier to control. This results in faster root development and a higher yield!  COGr is compressed and dried, for easy transportation and storage. This makes it ideal for the demanding grower.

cogr_content_1Three revolutionary fertilising products have been developed especially for use with COGr:

1. COGr Buffer Agent
2. COGr Vega
3. COGr Flores

These products provide the plant with optimal conditions for rooting, growth and bloom. COGr can be reused up to 3 times without any loss of quality. The COGr range is a proven system that is rapidly becoming the method of choice for growing in coco slabs in Holland. At the heart of this system are compressed un-buffered slabs of coco that require you, the grower, to soak with the special COGr buffering agent. Then feed with a dedicated COGr Vega feed during the vegetative stage switching to COGr Flores during the flowering period. These nutrients contain added humic and fulvic acids for improved nutrient uptake as well as silicon for increased resistance to pests and disease.

For growers wanting to use this system in pots the slabs are simply buffered in the normal way and then the contents are emptied into pots. Each slab makes between 21 - 25 litres of coco when decompressed. A 1 litre pack of COGr Buffering Agent dilutes to 500 litres, one application per crop. A 2 litre pack of CANNA COGr nutrients (1 litre A, 1 litre B) makes up 250 Litres of full strength nutrient. This is a universal formulation for hard and soft water.

COGr experiences

Martin and Gerhardt are two Swiss growers who have been growing since the early nineties. Since they grow in CANNA COCO products, they never want another medium to enter their greenhouse. Two years ago, when they switched from COCO to COGr they easily produced six harvests a year with one hand tied behind their backs.

On top of this, many professional growers tip their hats when they see and taste the harvested results of Martin and Gerhardt. “Personally I think the main advantage of COGr is the possibility to manage three harvests in a row, smoothly. In the past we used potting mix, it has almost ruined my back!” COGr boards are light as a feather and stiff, which makes them easy for transport. “It only takes an hour to harvest and plant 250 new plants. Gerhardt cuts out the old plants; I follow him and put new cuttings in the empty holes. No need for carrying new slabs or heavy bags of potting mix. There is no easier way.” Apart from the user-friendliness and cost savings this medium produces a superior, mouth-watering quality. Thanks to the lightness of coco the root development is extremely fast. It is striking that plants grown on COGr are better resistant to high temperatures. “Last summer temperatures were as high as 38˚C for many weeks. Still we harvested a perfect crop.”

Additives

CANNA COCO allows the cultivator to include the exact quantities of nutrients in the growth and blooming phases of fast growing plants. Other CANNA products, such as RHIZOTONIC (e.g. root development, stress relief), CANNAZYM (e.g. healthy root environment) and PK 13/14 (e.g. stimulating flowering) give additional support during various specific phases of the plant’s development.

Combined with these CANNA products, the plant can optimally focus on growing and blooming, guaranteeing high yields.
