Best Nutes I've Ever Used
These are PREMIUM nutes! I live in a legal state and grow my own medicine to save money and had tried two other nutrient combo systems before this but NEITHER of them gave me results like this combo does!! They are excellent and the size of the bottles is so generous that I have Subscribe and Save set to every 4 months! I never write reviews. I'll click the stars if I feel like it sometimes but for all the purchases I make, I almost never leave reviews. Something has to stand out BIG TIME for me to take the time to leave a review. See, I have Degenerative Disc Disease in most of my spine, Degenerative Joint Disease in my SI joints, my right hip, both knees, my right shoulder, and both hands. I also have diabetic polyneuropathy, fibromyalgia, gastroparesis, severe anxiety, major depressive disorder, CPTSD, PTSD, three different dissociative disorders, and moderate agoraphobia. There are more problems but it's getting hard to type so I want to get to the point. I use my medicine to help with my mental and physical health in a number of ways. Before these nutes, my flower was always falling short of what I needed. No shade on General Hydroponics or Fox Farms but they weren't doing it for my plants and so my plants weren't doing it for me. Then I found this combo and decided to give it a try and it is 100% the secret I had been looking for! My plants are happier, the strength is where I need it when it's harvested and partaken of, and my pain diminishes, my nausea diminishes, my appetite returns, my mood lightens, my cares diminish, and I can be a human being again... all because of these nutrients. I DEFINITELY RECOMMEND!

Impressive nutes!
3 weeks old Sunday and almost 1ft tall and wide. Need 3rd tent now. Have huge stalks already and exploding with growth. Better than last nutes I used on 1st 2 grow seasons. Love it.

Measurements gore
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.

This is the “good stuff”
I’m new to hydroponics, but this is really simple to use. Adjustments to EC are easy to make and you can literally see the results of your changes overnight in your plants. Highly recommended.
