GROWING SCIENCE

Nutrients are made from mineral salts. Salts always contain at least 2 elements. For example kitchen salt is made from Sodium (Na) and Chloride (Cl) in the form of NaCl.

When NaCl dissolves in water the Na and Cl will split.
Na has a positive charge (Na+). Positively charged ions are called cations.
Cl has a negative charge (Cl). Negatively charged ions are called anions.

The cations and anions in your feed tank can be measured by a EC/ppm meter because of their electric load. EC stands for electronic conductivity. It’s a way of measuring how conductive the water in your feed tank is (how quickly it allows electricity to pass through the water in your feed tank). A high EC means there is a high amount of cations and anions in your feed tank.

If water with Naand Cl– in it evaporated, the cation Na+ and anion Cl– would combine again to form NaCl. The Na+ acts like the north pole of a magnet and the Cl like the south pole of a magnet, they stick together and become a solid salt.

A plant up takes nutrients in preferential order which is called a redox. This means plants like certain elements more than others (luxury consumption).

AVAILABLE IN THREE VARIANTS

Snoop’s Premium Nutrients is available in three different variants to suit every type of grower both big and small.

NON-CIRCULATING

Our non-circulating nutrients have been formulated so that you achieve premium results from your run to waste system. The recipe is tailor made taking into consideration the fact that the nutrients pass through the root zone only once. When this happens the exact ratio of each element they require is delivered.

CIRCULATING

Our circulating nutrients have been formulated so that you achieve premium results from your recirculating system. When using our circulating nutrients your water usage is significantly reduced allowing for a more eco-friendly, economical method of growing. The recipe is tailor made taking into consideration the fact the nutrients pass through the root zone multiple times.

When nutrients pass through the root zone the cation NH+
4
is always taken first. This results in depleted levels of NH+
4
 every time the feed water recirculates. Our circulating recipe has elevated levels of  NH+
4
to solve this problem. It is advised you change your tank every 2-3 days or your  NH+
levels will be too low.

Elevating the levels of the cation NH+
4
 means we have to reduce the amount of the other cations. It is essential to keep the cations and anions in a recipe at equal levels, so when elevating the levels of the cation NH+
4
 it is essential to reduce the amount of the other cations. This is important for ph regulation in the root zone.

COCO

Our coco nutrients have been formulated so that you achieve premium results from your coco substrate. The recipe is tailor made taking into consideration the elements already present in the background EC of the coco due to the buffering process coco goes through.

The most common process for buffering coco is using potassium nitrate. To correct this potassium is reduced and calcium increased in the recipe. This is because of the cation exchange capacity (CEC ). Cation exchange sites are negatively charged sites on the growing media that attract positively charged cations. Certain cations attach easier to these sites. This is where elements from nutrients exchange with elements present on coco.

The cation exchange sites want to get rid of as much K as they can because they prefer Ca. A coco recipe gives the exchange sites the opportunity to take on Ca. As the exchange sites take on Ca, the K is released to the root zone. The plant still gets the same level of K as a result of this despite a reduced amount in a coco recipe. Elevated levels of Ca are required in a coco recipe because some of the Ca used to knock the K off the sites remains on the exchange sites.
