If a hydroponic system is not operated at the correct pH level, then many elements will be unavailable to a plant in the correct proportions and deficiencies can become apparent.

Pure Hydroponics recommends a nutrient solution pH range of between 5.5 – 6.2pH for all crop types, with 5.8 pH being the optimum level.

Specification :    17-20% concentration

Application notes :

Add few drops into your reservoir, stir and wait for the whole tank to stabilise (5 – 10mins) and the effect to get homogenous and measure.

SKU: N/A Category: Tag:

As pH increases naturally in a nutrient solution, it is more common to use pH down rather than pH up.
Concentrated acid/ alkaline can also cause a localised reaction with nutrients in the tank if it is added too strongly !

If you purchase our nutrient, you don’t have to get the pH up or down.
Our nutrient stock solution is pH balance to around 6.2 – which is a level that is optimised for most hydroponics cultivation !
