Molasses?

Yeah but if you getting strong sulfur smells from your pumice you might want to find a new source for pumice because mine never smells like that, it has no smell at all.
I'm talking natural pumice, not the stuff I use. I'm just saying, it's got sulfur in there.

You need to stop thinking I'm talking out my ass. I wouldn't say something if I weren't reasonably confident there was a strong base of evidence for it.

When I was in 4th grade Geology, we had a collection of igneous rocks. I specifically remember the pumice, as it was like a black rock that looked like a sponge and smelled of sulfur.

Did you not go to school, Yoda? Is that why you constantly think I'm dumb? Because you are uneducated?

You've kinda gone off the deep end...Ive used roots organic soil for years. You just now started using it and have not yet even got a harvest off of it man. Aren't you currently using MG natures cure? Did you go out and buy extra unprocessed pumice?

I just trying to see where you're coming from

PUMICE - Students will immediately notice that pumice is spongy or "full of holes" or vesciular. This characteristic makes pumice extremely lightweight; it even floats in water (you may wish to show this to your students). It is commonly light gray to blackish-gray in color. It is easily broken and has sharp edges. Like obsidian, pumice is volcanic glass; it thus looks glassy (especially with a magnifying glass) and lacks visible minerals.

Pumice forms during eruptions of magma containing large quantities of gasses, such as water vapor, sulfur dioxide, and carbon dioxide. The gas "froths" the magma as it erupts, forming bubbles. This is physically analogous to opening a soda can; carbon dioxide bubbles form in the drink as the can is opened. Like obsidian, the magma then cools quickly, preserving the bubble shapes. The gas often escapes, leaving numerous holes in the pumice. Pumice is used as an ornamental building stone. "Pumice rock" is also sold in beauty stores for cleaning dead skin cells from areas like feet or elbows.

I don't get what you mean, or what you're getting at. The argument's just that pumice contains sulfur. I use other things that contain sulfur at the moment. I have just started in the Roots with my small ones. My argument was simply that the pumice contains sulfur, and pumice is in Roots 707.

In short, you wont get enough sulfur from pumice for it to make a difference in the end product.


Roots Organics uses it for aeration.
RM3 seems to think less is more, and I agree. And as there is pumice in the medium, there's still some sulfur to it, and I think the properties of the pumice were intended to lend more than just aeration.

That may be, but again, it's not enough to make a difference.

So its a moot point to be taking a stance on

Correct "you think"

Meh. Either way.

I'm not starting shit here. I'm simply talking about properties of rocks. Yoda's only got a personal issue with me, otherwise he wouldn't debate the properties of something you'd at least think I'd study before I speak about. I get I've got a runaway mouth, but that doesn't mean the shit I say is baseless.

Oh, specifically, pumice contains trapped hydrogen sulphide. Not to a toxic degree. But that's why pumice is full of holes.
