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.

Ripen is a late flowering solution that is also known as a 'forcing solution' in the greenhouse industry. Will give you enhanced flowering size and yield.

The plant reacts by speeding the ripening process, in a last effort to spread its genes. - It brings to the plants all the mineral salts they need in a form easy to assimilate. - In case of a previous accumulation of nitrate or microelements, it helps metabolise these residues, which will improve the taste of the crop. - In case of a severe infestation of fungi or insects, it allows you to accelerate the natural cycle and get something out of a crop otherwise completely lost.
