FAQ

    • If Golden Tree is an All-In-One additive why do we have additional additives
      • We firmly believe that all you need to succeed is Base A+B and Golden Tree (if you need CalMag because of your particular setup, then this will still be needed). Our additional additives are optional, and we provide them as a resource for use at individual growers discretion.
    • How often should I use CalMag & Iron?
      • Use between 1-3x/week, more or less depending on how well your plants are responding.
    • How do you measure 5ml?
      • A good reference is that 5ml =1tsp.
    • What dose should I use in Soil vs. DWC or Aeroponics?
      • For soil and most mediums you should follow the label directions; between 2.5-5ml/gallon. In hydroponics setups like DWC and Aeroponics, you should use half dosage.
    • So, I still want to use additional additives - can I stack CalMag & Iron with Golden Tree?
      • Yes! Just keep in mind Golden Tree is a very concentrated product so make sure you are not overwhelming your plants.
    • Does CalMag & Iron have any harmful PGRs?
      • Absolutely not. No products from Humboldts Secret are made with any harmful or banned PGRs.
