VitaLink Coir Classic Growth Soft Water

 When using coco as your growing medium, it is advisable to use a coco-specific nutrient. Coco-specific nutrients, such as VitaLink Coir Classic, contain less potassium in order to take into account the potassium levels released from the media during the growing cycle.

VitaLink Coir Classic is an easy to use one-part nutrient that's available in either hard or soft water variants and as specific 'Grow' and 'Bloom' formulas.
VitaLink Coir Classic contains a range of other beneficial ingredients for your plants:
Vitamin B1 - is essential for healthy root development and promoting the general health of your plants. This vitamin is particularly beneficial if your plants have been under a lot of stress.
Humic acid - improves the uptake and transportation of nutrients and mimics natural growth stimulants. This in turn will help to promote fast and healthy plant development.
Fulvic acid - will further increase the absorption capacity of your plants roots. This will assist with your plants overall development and growth.

VitaLink Coir Classic Growth Soft Water 5L - for explosive vegetative growth.

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 PK 13/14

£6.00£49.00 incl. Vat
If you want the biggest fruits and flowers, CANNA PK 13/14 is the right product for you. CANNA PK 13/14 is a mixture of top quality nutritional minerals that stimulate flowering. It's easy to use and makes for high yields. PK 13/14 is suitable for any growing medium. Furthermore, it only needs to be applied one week only to the nutrient reservoir. If you do this at the right moment, you will get astonishing results!

Pure elements to stimulate flowering

CANNA PK 13/14 is a high grade mixture of phosphorus and potassium that is added during the flowering phase. Both elements play a big role during the generative phase of plants. Thanks to a special production process CANNA has succeeded in combining pure phosphorous and potassium in very high concentrations. This makes PK 13/14 available to the plant quickly and directly. Phosphorous (P) is a macro nutritional element for every plant. It plays a key role in metabolism and energy transfer. In the flowering phase, extra phosphorous is needed. Phosphorous strengthens cell formation in flowers, among other things. Potassium (K) is also a macro nutritional element. It is found throughout the plant and is necessary for a lot of its activities. It is essential for transporting water and nutrition (sieve vessels) and it is responsible for the plant’s quality and rigidity. In addition to this, it controls countless other processes such as sugar production. Potassium ensures that the plant can produce enough sugars during flowering, which are essential for the development of the flowers.

Perfect combination with CANNABOOST

There comes a moment during the plant’s development when the need for phosphorous and potassium increases greatly. If CANNA PK 13/14 is given at this moment you will satisfy the flowering plant’s increased needs and the fruits will achieve maximum development. CANNABOOST enhances the metabolism and has a strengthening effect on PK 13/14. This perfect combination will cause the plant to flower more lavishly.

Suitable for every medium

PK 13/14 is used with every medium and consequently it is used for cultivation on soil, in recirculating systems, when cultivating on coco and in run-to-waste systems. PK 13/14 is suitable for use when cultivating both indoors and outdoors.

Vitalink Buddy

£6.00£48.00 incl. Vat

VitaLink Buddy

VitaLink Buddy is a PK additive rich in potassium and phosphorus with added Magnesium and Sulphur to support the extra K and P which primarily supports the quality of the plant but also encourages maximum yield from plants i.e. growing bigger buds, producing more fruit and flowers. During the flowering process, an increase in the potassium to nitrogen ratio speeds up the reproductive processes and encourages plants to use more energy on their flowers or fruits leading to an increased yield.

Key Features:

  • Supports quality of the plant
  • Boosts yield
  • Improves flowering and fruiting quality
  • Enhances plant health
  • Faster, better results
  • Low concentrated PK solution – Buddy can be used throughout a longer period; from bloom week 3 until bloom week 8

ecothrive Neutralise

£6.00£60.00 incl. Vat

Neutralises Chlorine and Chloramine Instantly

Just a few drops of Neutralise and your tap water is ready for adding microbial products such as Biosys. It can also be used with soil, coco and hydroponic systems as a pre-treatment for irrigation water and nutrient solutions. Neutralise has been formulated to actively target the presence of chlorine and chloramine in tap water. Chlorine and chloramine are powerful disinfectants that are added to water supplies throughout the UK to kill potentially harmful bacteria. No doubt you will have smelt chlorine when running the tap or having a shower. Chlorine alone in tap water can create some unwanted harmful by-products so water companies are moving towards a more stable version of chlorine known as chloramine. The procedure involves mixing ammonia into chlorinated water. Chloramine is far more persistent than chlorine alone, making it more effective at killing bacteria right to the point of drinking your glass of tap water, or watering your plants.
