How to use Dutch PRO - PH Grow

\npH can fluctuate throughout the cycle of the plants. \n \nIf the pH goes outside of the range of between 5.5 - 6.5, the plants may stop up taking all the micro and macro nutrients, leading to signs of a deficiency even though there is enough nutrients in solution. \n \nThe pH needs to be monitored in order for the plants to continue up taking all the micro and macro nutrients. \n \nMix a small amount of pH adjuster at a time. \n \nThe best way to do this is to first dilute a small amount (1ml or so) of pH down into a separate container with about a litre of water and then slowly add this water, checking the pH of the reservoir after every small portion gets added, stop adding to the solution when the desired pH is reached. \n

Safety notice

\nPlease be aware that pH Down and pH up are extremely aggressive liquids that are corrosive to many materials. \n \nExtreme caution should be used when handling aggressive liquids, as any contact with skin may need medical attention. \n \nWe recommend you use gloves and safety goggles when working with aggressive liquids. \n \nWash any equipment thoroughly after using them with aggressive liquids. \n \nNever mix pH up and pH down. pH up is a strong alkaline substance, whilst pH down is strongly acidic. A neutralisation reaction may occur in which the elemental components of these substances recombine into salt and water. This reaction is exothermic and can produce a lot of heat that could be explosive. \n \nData Safety Sheets PH \n Dutch PRO Products \nSDS pH- Bloom \nSDS pH- Grow SDS pH+
