Golden Tree Feed Chart

Mixing Procedure

1) Fill your reservoir with water.  It may be filtered or tap water.  If you use filtered water you may need to add some CalMag & Iron.

2) Add HUMBOLDTS SECRET NUTRIENTS listed on the feed chart (Shake each bottle a little bit)

3) After you add your nutrients, adjust the PH so that your end mixture in your reservoir is between 5.5 and 6.5 (If needed.)

4) Can be used in Soil, Coco, Deep Water Culture (DWC) and Aeroponics.  Typically less nutrients are used in DWC. If you grow in Hydroponics it is recommended that you use  Golden Tree at a lower dose and use Plant Enzymes. We suggest you play around with the amounts of each nutrient and find out what works best for your setup as there are many variations to growing.

Additional Information

1) In order to have a successful grow growers should use at minimum Base A, Base  B & Golden Tree. 

2) For Veg: Add 1-2ml of Golden Tree per gallon to your reservoir. Then, add your base nutrient until PPM levels of the reservoir mixture reaches between 800-1000 (Hanna Scale)

For Flower: Add 2-5ml of Golden Tree, then add base nutrient into your reservoir  until your PPM levels of the reservoir mixture reaches between 1000-1300 (Hanna Scale, which is 2.0-2.6 in EC.) Remember that this is a rough estimate. Strains and growing mediums vary, some will enjoy higher PPM's and some lower.  Flushing at the end is not necessary.

Shake bottle and measure out 2-5mL per gallon of water.

Dilute Golden Tree into a full watering can or reservoir and stir to thoroughly mix.

Feed to the base of your plant, or use as a foliar spray. For optimal results, feed Golden Tree 1-3 times a week throughout your entire growing season.

We are confident that you will be pleased with your product and offer a 6 month 100% satisfaction guarantee.

Frequently Asked Questions

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

For soil and most mediums you should follow the label directions; between 2-5ml/gallon. In hydroponics setups like DWC and Aeroponics, you should use half dosage.

Yes! Although you will find you do not need to. Just keep in mind Golden Tree is a very concentrated product so make sure you are not overwhelming your plants.

Golden tree is amazing

They shipped it really fast and I’m happy with their customer service. This product is amazing it helps everything in my garden from peppers, tomatoes, to trees, and shrubs. A little goes a long way and you will definitely be happy at harvest time when you have pounds of peppers and tomatoes for canning.

How do I know?

I am using the full line of your products and love how plants are growing. How could I ever tell if the Golden Tree product is magical, or if it is your total line in combination that makes things work so well. PS...I also add in some other brand products during the summer. Love your products...not so much your survey question prompts!! Peace
