They had bags of Organic Humus at HD and it looks like the main ingredient is peat. I'm using a peat mix. Is thier any benefit to putting some in my mix, looked wet and heavy too?

Use it as you would regular compost but if it's mostly peat then it's just a richer and heavier version of the high porosity peat based mixes we rely on for MJ.
You could probably use it straight wil alot of perlite and vermiculite but then again I don't know the product.
You could mix it half and half and put a clone in it to test it before wasting a whole grow on the possibilty of it being good.

Thanks Suby, sounds good

I have not got it yet, it seemed very wet, did yours seem that way, not airy and fluffy like peat mix

I used it on in my mix for some honeydew melons last summer

I wouldnt think it would be to hot to use by itself. But I am with Suby add LOTS of perlite. It is pretty dense.

I thought humus is that yummy spread that I put on my pita...

mmm...

Organic Humus is the end product of decomposition of plants and animals, and the dead cells of soil bacteria and fungi. Humus improves the cation exchange capacity (CEC) of the soil. This means that Humus can hold onto nutrients in the soil and then release them later as the components in the soil water solution change.

Peat Humus can consist of hypnum moss, reed sedge peat, or woody peat. It has a low moisture-holding capacity, contains a small amount of nitrogen, and usually has an acidic pH.

Peat humus originates from hypnum moss, reed sedge peat, or woody peat. It is in such an advanced state of decomposition that the original plant remains cannot be identified. Peat humus is dark-brown to black with a low moisture-holding capacity. Unlike the other peats, it contains a small amount of nitrogen (2 to 3.5 percent). Peat humus, also known as black peat or Michigan peat, is quite heavy compared to the other peats. Its pH varies greatly (from 4 to 8), and it is characteristically sticky when wet.

Two types of black peat are found in the trade. The first, amorphous peat humus is highly acidic and virtually structureless. Any water it holds is mostly unavailable to plants. When it dries, amorphous peat humus becomes lumpy. It turns to dust when broken apart.

The second type of black peat, granular peat humus, contains humates which form aggregate particles. The aggregates give granular peat humus a high air capacity and make it permeable to water. This humus is used for improving very sandy or gravelly soil. Overall, the lack of water-holding and soil-loosening capacities of peat humus make it unsuitable for most horticultural purposes.

Mmmmm..so if I'm using a Peat based mix with perlite and lime would this be a good thing. I'm using PBP and mollases

peat moss scares me. so acidic. ewwwwwww
