Hey just wondering what everyone's using for humic acid/fluvic acid/seaweed in hydroponics DWC? What's the best one out there that may possibly contain all three. I like general hydroponics but I'm open to using other brands.

I like Mr. Fulvic a lot. Favorite liquid seaweed is Age Old brand-it's concentrated and smells like kelp. Lots of them are really watered down. Blue Planet brand is decent too.

Do you know if it can be used in DWC? what does the label say?

It definitely can. They’re both water soluble. I’ve mixed a res with it for three days plenty of times and it wasn’t a problem.

just be careful when you start adding in organics to hydro. they "can" get your res a bit funky. i'd add one at a time when starting out and see how they react for a week or so.
