Review: 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! Review: A+++ great product for weed grow - Been adding this, seems to do a great job. I’ll be sticking with this company when it comes to nutrients. ## Features - Fuel Plants With Complete Nutrition: Humboldts Secret Base A and B delivers a full-spectrum formula with nitrogen, phosphorus, potassium, calcium, and magnesium.

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 ### ⭐⭐⭐⭐⭐ Best Nutes I've Ever Used *by M***T on 21 August 2026* These are PREMIUM nutes!
