Growth Technology pH Test Kit 250ml Up & Down Solution

GROWTH TECHNOLOGY PH UP 250ML

Plant growth is largely influenced by the pH of the nutrients solution being used. Having incorrect pH levels can result in your plants growth being hindered and your overall yield being lower. This solution is designed to increase the pH of your solution to ensure that your plants are growing in the most ideal conditions. 

Due to the solution being so highly concentrated only a few drops are required to change the pH levels of your solution. This bottle is therefore guaranteed to last for many uses, making this purchase excellent value for money. 

Never use this product in conjunction with pH Down. If you have used too much pH Down in your solution discard of this and do not combat it by adding this solution. 

pH Up is 25% Potassium Hydroxide and therefore care should be taken during use. If any does come into contact with your skin rinse immediately with clean water.  

VITALINK PH NARROW SPECTRUM TEST KIT

The VitaLink ESSENTIALS pH test indicator kit uses a solution known as universal indicator to change a small sample of your nutrient solution to a different colour. 

Compare this colour to the spectrum chart to indicate what pH your solution is reading at. 

Although not as accurate as using a pH meter to analyse your nutrient solution, this indication kit is a quick, precise and cost efficient measure giving over 100 readings.

Covers a pH range of 5.6 to 7.4 measuring in 0.2 increments. 

Easy to use, dropper bottle – colour change test: 


1) fill the vial (supplied) with solution 
2) add 3 drops of test indicator 
3) Shake well 
4) Match colour to chart (supplied) to read pH 

GROWTH TECHNOLOGY PH DOWN 250ML

Growth Technology pH DOWN contains orthophosphoric acid (H3PO4). The concentration is 81%, which is very strong so handle with care. 

Some other products on the market are considerably weaker so check the concentration before you buy. 

This is a very dense liquid and should feel much heavier than water.
