Review: Mix this humic/fulvic acid with kelp or kelp/fish blend...Watch your plants grow!! - Excellent product with phenomenal growth nutrient uptake support..Buy it, and some kelp/seaweed formula! Use along with your normal nutrient soil program..fox farm trio (what I use). Anyway, I alternate feedings between fox farms and humic/fulvic acid and fox farms, etc. In between these nutrient feedings, I feed water with cal mag and nectar of gods yucca. I add silicone during veg along with fox farms or humic/fulvic/kelp/fish blend, so not to have issues with cal mag precipping out. You don't want to use my suggested regiment every feeding, or with fox farms together, etc...key is to alternate when you give your base nutrients (along with ph'ing water to 6.8 so root zone will be getting 6.3_6.4). I've read the real suggestion is to go once humic/fulvic/kelp once every 3 weeks, but hey, I want growth,! I also add a fish part to my kelp (comes as fish/kelp in one). My plants take the 2-3 times per month of this humic/fulvic acid and kelp/fish blend.. no prob! You want to use double the humic/fulvic acid coupled with half dose seaweed kelp/fish blend (it stinks!). In my case, it's 4 oz humic/fulvic and 2 oz kelp/fish blend..per gallon h2o. Then, watch the explosion of growth and greenification!! My research on humic acid /kelp blend is based on a study done at the University of Virginia, I believe. Unless you want to add humis, etc and other soil additives upon transplanting,this liquid humic acid/fulvic acid blend is the easiest way to add consistent nutrient supply to the root zone (albeit diluted vs the humis soil additives method). Great product, cheap, and Thanks so much!! Hope this helps you grow more happiness too!!
Review: Noticeable lawn health boost, easy to use - I used this humic acid concentrate on my lawn to help improve soil quality, and it has been a solid addition to my lawn care routine. It mixes easily with water and is simple to apply with a sprayer. After a few uses, the lawn looked healthier overall, with better color and more even growth. It’s not an overnight miracle product, but it seems to support long-term soil health and helps the lawn respond better to regular watering and care. A little goes a long way since it’s concentrated, so the value is there. Just make sure to follow the dilution instructions carefully. Overall, a reliable product if you’re looking to improve your lawn’s soil condition and give your grass a steady boost.

## Questions & Answers

**Q: Right now (!) tell the percentage of humic acid in this gallon. Why is it not listed on the bottle? Other sellers do this? How know this is legit?**
A: 12% Humic Acid is available on Amazon. Just search for it. According to the manufacture, this stuff  contains 8%; but they aren’t willing to label their product as such, so do you trust them? Personally, I’ll buy the 12%. Although it costs more per gallon, you’re actually getting more per dollar.

**Q: What percent humic does this have?**
A: It's weaker than humic acid sold by other brands. Can tell as soon as you open the bottle.

**Q: Why is guaranteed analysis of this product not listed anywhere? this should not be an amazon choice product until it can be proven.**
A: I don’t know why there is no guarantee analysis but I have been using this to bring my ponytail palms back from having root rot and it is working fantastic

**Q: What is the active and inactive ingredients?**
A: What you want to know is how much carbon is in this product compared to oxygen. Common humic acid has about 60% carbon and 40% oxygen, but that varies depending on the source. You also want to know how much humic acid is in this product. The answer is 8%. (NOT 80%)

### ⭐⭐⭐⭐ Great product, a bit diluted.
*by C***R on May 9, 2020*

The product is great. It's high quality and I may buy it again. It's not as concentrated as other products. This is a problem for me. It could be significantly more concentrated, so you end up paying for a significant amount of water. It's not a rip off though. It's a good deal and because it's more diluted it's not as messy and it will not clog up my sprayer ever. With thicker products I sometimes cut them with water so it's smoother in my sprayer.
