Canna Aqua Vega (A&B Set)

£13.00£31.50 incl. Vat

CANNA Aqua Vega

CANNA Aqua Vega is a fast working nutrient for plants containing all the essential elements for optimal growing. The growing phase is important, because during this phase the plants lay the basis for an exuberant bloom and yield. Aqua Vega is used in recirculating systems, such as NFT or ebb and flow systems.

Advantages of CANNA Aqua Vega

  • Aqua Vega is easy to use and dissolves directly. Aqua Vega nutrition contains pH-stabilizers, so there is no need to adjust the pH
  • Aqua Vega ensures a strong plant with vital growth spurts and excessive root development
  • Directly absorbable nitrogen compounds, high quality EDDHA iron chelating agents and trace elements guarantee an ideal start for the bloom

Why A&B nutrients?

CANNA Aqua Vega nutrients consist of two parts, an A part and a B part. We separate these parts for a reason. As it happens, if some of the elements in part A and B are thrown together at the same time, they clog together. The plant cannot absorb this. That's why you should first add the A component and then the B component

Mills Vitalize

£27.95£540.00 incl. Vat
It’s the most abundant element in the earth’s crust and of vital importance to all life on the planet. Everyone needs silicon. Both man, animal and plants grow stronger from it and are better equipped to fight diseases and bacteria. Despite these facts, the element is not used much in the horti- and agriculture. The main reason is because silicon is very hard to extract. Or so it was, until recently. Mills Silicon sprung to life when a professor developed a revolutionary, unique and patented method to liberate silicic acid from the silicon element. Granting Mills to the sole right to use his invention, this makes Mills Silicon the only nutrient that provides your crop with everything it needs.

PH Test Kit – Liquid 6 – 7.6

£2.50 incl. Vat
Low or high pH levels affect the availability of the minerals required by the plant. The correct pH range for hydroponics is between 5.5 and 6.5, for soil it is not so critical, but generally around 6.3; outside of these figures nutrient problems will quickly occur as minerals become insoluble. The nutrient strength needs to be matched to the current stage of plant development. Too high a concentration can quickly burn a plant, whilst too low produces pale, weak growth. Measuring is knowing. Good results are attainable by anyone prepared to stick to this rule. Whimsical guesswork rarely leads to success! The Nutriculture pH Test Kit allows quick and accurate monitoring of pH levels in your nutrient solution. For accurate acidity testing follow the procedure below. •Take a 2ml sample of solution from the tank in the test tube provided. •Add 2 drops of reagent. •Shake the test tube and compare the colour against the test strip to determine the acidity. •Discard the test solution and rinse out the test tube. •Adjust the pH of your nutrients and retest if neccessary.

Canna Cannazym

£7.50£69.50 incl. Vat
CANNAZYM CANNAZYM is a high-quality enzyme product that speeds up the process of breaking down dead root material and activates beneficial micro-organisms. CANNAZYM also helps plants take up nutrients and increases the resistance against diseases. Enzymes are substances that speed up the reactions in living organisms. For example, enzymes play a vital role in our digestion. The enzymes in CANNAZYM have many benefits:
  • They turn dead roots into minerals and sugars. This is important, because these minerals and sugars make up a valuable source of nutrients for the plant. CANNAZYM consists of more than 12 different kinds of enzymes to which vitamins and extracts of desert plants are added. These elements improve the uptake of nutrients and the plant's defence system. Also, vitamins stimulate the production of hormones.
  • They help form new roots. The easy-to-absorb vitamins in CANNAZYM also stimulate the plant to form new roots. This increases the health of the plant.
  • CANNAZYM prevents bacteria and harmful mould. Dead roots form an ideal environment for moulds. They are a threat to the healthy roots. The moulds cause stress to the entire plant and stunts any new growth. Also, CANNAZYM prevents rotting, so there is no formation of toxic substances and the risk of a disease is considerably reduced.
  • CANNAZYM improves the soil environment. A fast breakdown of root remains creates a balanced hydrological regime and good aeration in the root environment.
CANNAZYM is indispensable if you are going to reuse substrates for growing. The root remains will be rapidly broken down and transformed into advantageous nutrients; infections will be prevented and the air/water relation in the root environment will be improved. You can use CANNAZYM during the whole growth cycle.
