My flowers are cup quality, every time. Top quality nutrients, broad spectrum, easy schedule and dosing and super reasonable compared to other brands with comparable offerings. On average, I'd say my return on investment in yield:nutrient is about 50:1. Hard to argue that. I'm a believer. Review: This stuff seems to work, but the wording on the back is hilariously ambiguous, and I'm sure I'm adding the wrong amounts. It says "5-9ml/GAL A + B". First up, mixing metric and imperial measurements like that is confusing - it's a bit like saying "5-9 inches per kilometer". Beyond that, this wording could mean: 1) "5-9ml of A + B combined per gallon of water you are adding" 2) "5-9ml of A and 5-9ml of B per gallon of water you are adding" 3) "5-9ml of A + B combined per gallon of water in your tank" 4) "5-9ml of A and 5-9ml of B per gallon of water in your tank" I think it's option 2, but as a hydroponics noob I could see it being 3 or 4 too (maybe the plants pull all the nutrients out of the tank water so you need to replenish - dunno). Here are a few formulations of what I think they mean, using a consistent measuring system: * mix 1-2ml of each of A and B per liter of water you add * mix 1-2 parts of each of A and B with 1000 parts water, then add to your tank * mix 0.2-0.3 fl oz of each of A and B per gallon of water you add You probably boost your chances by sticking to metric here as they're calling for a dilution of roughly a thousand to one, and that's hard to do with imperial. Also, invest in a pipette because eyeballing 9ml is a challenge for the best of us. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01IM88KKI | | Are batteries included? | No | | Brand | Humboldts Secret | | Customer Reviews | 4.5 4.5 out of 5 stars (1,982) | | Date First Available | 14 September 2016 | | Item Form | Liquid | | Item Weight | 906 g | | Item model number | 4316245515 | | Liquid Volume | 64 Fluid Ounces | | Model number | 4316245515 | | Number of Items | 2 | | Package Dimensions | 21.11 x 20.19 x 13 cm; 907.18 g | | Specific Uses For Product | Plant Growth | | UPC | 648260730437 | ## Product Details - **Brand:** Humboldts Secret - **Item Form:** Liquid - **Item Weight:** 32 Ounces - **Liquid Volume:** 64 Fluid Ounces - **Specific Uses For Product:** Plant Growth ## Images ![World's Best Base Nutrient System: Humboldts Secret Base A & B Bundle - Liquid Nutrient/Fertilizer For The Vegetative & Flowering Stages of Plants (2 Quarts) - Image 1](https://m.media-amazon.com/images/I/41bOK6oMlXL.jpg) ![World's Best Base Nutrient System: Humboldts Secret Base A & B Bundle - Liquid Nutrient/Fertilizer For The Vegetative & Flowering Stages of Plants (2 Quarts) - Image 2](https://m.media-amazon.com/images/I/51IApJVVI5L.jpg) ![World's Best Base Nutrient System: Humboldts Secret Base A & B Bundle - Liquid Nutrient/Fertilizer For The Vegetative & Flowering Stages of Plants (2 Quarts) - Image 3](https://m.media-amazon.com/images/I/51L3d+mA3VL.jpg) ![World's Best Base Nutrient System: Humboldts Secret Base A & B Bundle - Liquid Nutrient/Fertilizer For The Vegetative & Flowering Stages of Plants (2 Quarts) - Image 4](https://m.media-amazon.com/images/I/51OdMGZh0FL.jpg) ![World's Best Base Nutrient System: Humboldts Secret Base A & B Bundle - Liquid Nutrient/Fertilizer For The Vegetative & Flowering Stages of Plants (2 Quarts) - Image 5](https://m.media-amazon.com/images/I/51Z0aRQ7K3L.jpg) ## Questions & Answers **Q: What is the Nitrogen break down on the label?** A: NPK of Base A and B is 4-0-1 and 1-4-2, respectively, from Nitrate Nitrogen. **Q: How do I know how much to use in my tower garden?** A: We used 400 ml each if tub is full (20 gallon) to start. Then 200 ml once a week and that worked for us. If your plants aren’t producing they may need more nutrients. **Q: Is this post sold as 2 32 oz containers of base a and base b? or two 16 oz containers of base a and base b?** A: It is 2 bottles each contains .946 liters or 32 ozs **Q: Does this nutrient line work well in soil?** A: I have been using these along with Golden Tree, SuperThrive, Heavy Boost & an enzyme blend. I use this combination every other watering. The alternate watering I use the Fox Farm nutrients. Last crop was excellent. This crop may be even better! Will most likely continue using these 2 nutrient sustems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***Z on 20 January 2026* I use the whole Humboldt's Secret nutrient line on plants grown indoors in tents with automated lighting, circulation and exhaust fans and manual feeding, watering, temperature and humidity controls.
