Why bother?
Humic acids are part of the Fulvic acid chain. All Humic/Fulvic products are not the same!
90%+ are crappy weak and from poor sources of Langbinite.
Then they get watered down to 5% for bottled use.....You might do better by giving the plant the blood from you shooting yourself in the foot...
We organic farmers (of all things) have known about the best source for H/F acids for a long time.
BIO AG products! FUL HUMIX is my go to product. NO better, clean, purest and most powerful Humic/Fulvic on the market- PERIOD!
Use up what ya got and go BIO AG and use the best......
The guys at Build a soil would tell you exactly the same thing I just did......
BIO AG for the win!
