  • Chemboys Citric Acid - 1lb

    Chemboys Chemboys Citric Acid - 1lb

    In stock

    Use Chemboys Citric Acid to help treat soil alkalinity. If your soil has high alkalinity for a particular plant, citric acid can be mixed in with the soil to help raise the soil's pH. In low doses, Chemboys Citric Acid can be a beneficial repellent of certain organisms and pests.Citric Acid lies below 4.0 on the pH scale, meaning that it is acidic and potentially corrosive. The optimal pH for plant growth is between 5.5 and 7.5

  • Sale -10% General Hydroponics PRO pH Down 2.5 gal

    General Hydroponics General Hydroponics PRO pH Down 2.5 gal

    In stock

    General Hydroponics Pro pH adjusters are based on completely different technology than our traditional smaller sized adjusters offering. New non-mineral based acids and bases will not add nutrient value like the use of phosphoric acid or potassium hydroxide. They are safer to use as well as compared to mineral based adjusters. This is due to having a zero rating score for all safety categories on the HMIS scale as well as being non-corrosive and non-caustic. This means there are no HazMat fees to ship these products like other pH adjusters. Use Pro pH UP or Pro pH DOWN to effectively adjust the pH of nutrient solutions or irrigation water. GH Pro pH adjusters are highly concentrated and available in commercial sizes. Non-Caustic Non-Corrosive Do not need to be shipped Hazmat like other adjusters Alternative to harsh mineral hydroxides Triple zero HMIS score Does not contribute nutritional value like other adjusters Concentrated Formula

  • Sale -10% Ambrosia Cropz pH Up Formula - 5lb

    Ambrosia Cropz Ambrosia Cropz pH Up Formula - 5lb

    In stock

    Ambrosia Cropz pH Up is a dry pH-raising product from Ambrosia Cropz, a Colorado company that makes a water-soluble hydroponic nutrient line. You dissolve it in water to make a liquid stock concentrate, and Ambrosia's mixing chart is written for injector stock tanks. This listing is the 5 lb bag. How to use Weigh out the amount of pH Up that matches the concentration you want and the gallons you plan to mix. Fill your stock tank with the amount of water you want. Add the pH Up and agitate or recirculate until mixed. Ambrosia's mixing chart pairs one 5 lb bag with 20 gallons of water, or three 5 lb bags with 60 gallons. Ambrosia notes that you are highly unlikely to need more than 37.85 ml/gal (a 1% injection). Good to know Ambrosia's batch mixing instructions have you test a sample of the fully mixed nutrient solution for EC and pH, then adjust as needed. Read and follow the label.
