I don’t use it all the time but when I get a fast grower heavy eater I use this to give it a boost. Everybody should have this in their lineup

I didn't need the Iron in the kelp extract I've been using in the past. I had been making this mistake in the past and didn't even know. Thanks for the knowledge. Love you all!

Always makes a difference I always make sure I got some on hand.

I like the fact that it doesn’t include iron, as I use silica as well. Very high quality. Thanks Build@Soil!

Does a great job of putting micro nutrients and humid acid back into the soil. Seems to keep those high intensity LEDs from scorching your canopy.

Has my plants at the mountain tops haha. Really though I’m running out of room in my 4x8 tent, this stuff works. I swear I see 3 almost 4 inches of growth in one day when spray with big 6. Great stuff thanks Jeremy and team.
