I have messed with ligna peat. The peat alternative made from triple ground redwood bark. I really like it. usually less then 50$ a yard. Really good for making heavy compost based soil lighter. It's in the vermi fire i believe. Similar ph to peat. Some of my favorite soil mixes i have made have it. It's also in vermi and vermifire.

Bark is typically a filler and can be antimicrobial. Potting soil companies get it free or super cheap ($10-15 yard) from the timber industry. They then list it as "forest humus" or "composted bark fines" or some other good sounding name. It really does nothing beneficial in regards to plant growth and health. There's a reason we use it as a weed suppressing mulch in our ornamental landscapes.

I would suggest trying similar mixes without the bark and I bet you would get even better results.

And the cost is really the killer for me with the Pitt Moss. I love the concept, but it is so expensive and lacking the microbiology I get when I use peat.

the one who comes with proper replacement for peat will make much money
(peat is totally not alright to use , destroying thousands of year old ecosystems is not allright...and its stays destroyed)
i use it to from bb lightmix...but i am a asshole as long i use it...its fact..
ok some of you will say i will stay an asshole also when skipping peat..might be true...

It's really pretty cheap until you add in shipping. While peat is compressed, this stuff isn't. Not on purpose anyway. An obstacle to overcome.

While it may lack the microbiology, mixed 50/50 with peat that's soon overcome. It actually makes a really good mix. Superior to the ingredients alone.
My only concern is longevity and is it eventually going to collapse?

I appreciate you sharing your thoughts and results. 😀

Perhaps if they had a west cost distributor with a long track record and an excellent reputation?
Just saying...
So what is the stuff? Silicone impregnated cellulose?

Anybody have an MSDS? I can't find one.

I grew up in that area... no paper recycling plant nearby... I bet it is coming from OH.

Any more details?

Kis:
The tripple shredded redwood bark is a verry fluffy unique texture that really breaks down slow. Its not like fir or pine bark fines or anything else. Its extremely course and stringy.
I have used so many soil recipes. I have around 500+ yards of soil in use right now. Redwood in the right proportions just crushes it The hardest. It is for making a compost based mix lighter. Not as a base itself. Its sort of an amendment like perlite is to get your drainage and texture right. 20% total volume is plenty. That's how i use peat also.

I want some honest feedback of some revolutionary products I engineered. No gimmicks or bullshit, just please give me an honest evaluation. Experienced growers preferred as I want scientific data and not someone to stroke my ego. It’s a grow media component similar to coco made of Pacific Northwest forest products I’m calling “Oregon Peat” and the other is a living biologically active carbon source that is composted proprietary ingredients “Karbon”
Thanks for checking it out

Send a bale over!

pine needles and saw dust? Composted of course...

[h.h.]

"Pacific Northwest forest products" to me means nothing. Redwood, pine, poison oak? Whatever they send you?

Getting past the self promotion and getting back on subject.

OMRI lists PittMoss as paper and nothing more. Listed for mulch or as a compost amendment. Nothing about being a soil amendment.
With that, it doesn't appear to be just torn up paper.
Claims are that the original experimentation consisted of newspaper in a food processor. Perhaps they just got a bigger food processor?
