Feed Chart

Mixing Procedure

1) Fill your reservoir with water (filtered or tap). If you use filtered or RO water, you may need to add CalMag & Iron.

2) Add Humboldts Secret nutrients listed on the feed chart (shake each bottle first).

3) After adding nutrients, adjust pH so your reservoir mixture ends up 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. Adjust amounts as needed for your setup, as plant varieties and growing conditions vary.

Additional Information

1) For best results, use at minimum Base A, Base B, and Golden Tree®.

2) Growth: Add 1–2 ml per gallon to your reservoir, then add your base nutrient until the reservoir reaches 800–1000 PPM (Hanna scale).

Bloom: Add 2–5 ml per gallon of Golden Tree®, then add base nutrient until the reservoir reaches 1000–1300 PPM (Hanna scale), which is approximately 2.0–2.6 EC. These ranges are a starting point. Plant varieties, growth stages, and growing mediums vary. Some plants prefer higher PPMs and some lower. Flushing at the end is not necessary.
