Fulvic Acid

[MadDoctor]

I would like to know if anyone here uses or has used in the past Fulvic Acid for their grows.
It can be both added to the feed and used as a leaf spray.
I used it my first auto grow so I can't know what would've happened if I didn't. But still after spraying the leafs with it the plants seemed to be happier! It's also pretty cheap if you buy the pure powder rather than getting it already diluted, 10€ will last you for at least one grow.
So what's your take?

I have never used it, this type of stuff comes under "not needed" as far as i'm concerned as it's more money all the time. but maybe i would be a better grower if i started to use "stuff" like this.Will keep my eye on this thread as i also need to know the answer, thanks.

Fulvic acid is similar to humic acid but contains more oxygen.Humic acid is in a lot of our organic nutes and is relatively common.I use humic acid on all my grows.

I've used fulvex before and didn't see any real difference. I use humic acid in all my feed schedueles also. But I do quasi organic growing in coco, and I think it helps.

Well, if you buy the liquid product, it will cost a lot, if you buy the pure powder is really really cheap I paid 10€ for 30 grams of 95% Fulvic powder delivered, you mix it with water in proportions of 2000:1, 1000:1, so it's 15/30 Liters of foliar spray... I guess one experiment is feasible for most.
For my imminent grow I'm buying a digital PH meter and I'll be using using a nute tank, so I will be able to see if it affects the PH of the solution.

Fulvic and Humic acids are great for plant growth. Ohio St actually did a study on the effects of humic acid if you want to check it out. http://www.biosci.ohio-state.edu/~soilecol/Full%20articles/2006/Effects%20of%20humic%20acids.pdf
