Humboldts Secret Base A & B Liquid Hydroponic Fertilizer | Complete Hydroponic Nutrients for Indoor and Outdoor Plants | Supports Healthy Vegetative Growth and Flowering Stage | 1 Gallon

Excellent product. Used now for a little over 3 weeks, Shipper made mistake that I did not catch, but spouse did. They sent 2 bottles of "A" instead of one each. Honestly was impressed with just the "A" part. Been using the mix of "AB" for about 2 weeks and "*%&<÷>=/&". Plants using about 1 gallons every other day. Mixed as recommended, will last a long time at the rate of use. 6 teaspoons per oz. 32 oz per bottle (192) feedings..... I recommend this product. HUMBOLTS! NICE. Thanks

I’ve been using these for my “tomato’s” and honestly works great makes your plant grow like crazy if it’s your first time maybe try there stater kit

Great for my hydroponic Lettuce

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.

Exactly what I ordered! So glad for it.

Great product

This is my first attempt at hydroponics! This product was easy to use and my garden is growing like crazy, so it works! My plants are very healthy and taste delicious! The greens grows so well that I have to pick off of them and eat a big salad daily so I don’t run out of space! Happy customer!

The product itself is decent but the seal and cap both caused the product to leak all inside of the box it was shipped in. Lost close to half the bottle due to a defective seal and cap
