I was doing some reading and came across the use of humid acid to increase oxygenation, nutrient uptake and decrease lockout conditions. I did some further reading and found that the molecules of humid acid are to large for root pours. Even a little reading further and I came across the use of Fulvic acid in hydroponics for the main reason of increasing nutrient uptake and decreasing lockout conditions.

Does anyone have experience with either of these extracts and/or can speak to the purposes of use and the end result?

Thanks!

the reason fluvic acid is better in dro is the molecules are smaller than humics and they are more readily absorbed thru the root zone. Humics require more natural mineralization in sol for the goodies to be accessible. Humics = larger molecules...…. fulvics = smaller molecules
