Due to concerns over safety, we have reformulated our pH adjusters to a 25% strength and called them 'EASYCONTROL 25'. This means that it is easier to use for novice growers as there is less chance of overdosing. There is a reduced price and it is safer to handle. Quality adjusters are necessary to control the pH of nutrient solutions.
Please Note: Do not store pH Up and pH Down next to each other.
