For use in a 5-1-1 mix just about any brand of a quality peat moss should be OK - Silica

Cedrick, it looks to me that it is sphagnum moss, not peat moss. Do not use it. I used Google to translate peat moss into Dutch: veen moss.

Im confused now Vladimir. On Wikipedia it says sphagnum = peat moss = (veenmos in my language)

I would be confused as well :-) 'Peat moss' is a product that is mined/harvested from the decomposed remains of various bog plants. Here in the US, most peat is derived from reed sedge (Phragmites) but the vast majority of peat comes from mosses, with 'sphagnum' being a group label for about 100 or more different moss species. Hence the referral often to 'sphagnum peat moss'. Sphagnum moss is also sold as a dried product, often used for lining hanging baskets or topping container plantings. This is NOT decomposed (therefore not peat) and cannot be used successfully in a potting mix.

What the OP is showing in his link is a pressed brick......and it looks to be a pressed brisk of sphagnum peat. It is certainly not the dried moss!! If broken up into finer particles and properly hydrated, it should make a suitable potting mix ingredient for the 5-1-1. But it needs to be in fine, almost individual particles liked typical milled peat moss is. I'm not at all sure how easy this will be to do with the linked product.

I take it 5-1-1 is the NPK make up of fertiliser? Seems an unusual ratio!

Thanks for the info. I understand it now. So if i purchase that, properly hydrate it, and grind it up nicely, i could use it in my mix. I don't have many options because around here its hard to come by. And it looks like its for a decent price. Vladimir thank you for that picture, it shows me very well what the difference is. I have the pine bark and the perlite already, its much easier to come by.

Larry, no. 5-1-1 is the components of the potting medium. Feel free to google. There are great explanations of what it is and why it is what it is. Gritty mix is the other popular home made mix.

Cederick, no you can't use it because it's not composted. Sorry.

Even if i grind it up and let it hydrate? If not, is there a proper substitute for peat moss because I can't get my hands on the dried version over here. Coco?

pip311, is there such a thing as composted peat moss? Perhaps you are referring to pine bark?

Peat moss is the dead naturally composted stuff. That is peat. The recently alive stuff that will suck nitrogen away from your plants.

As far as I can tell from a translation of that website - that brick is indeed peat moss. One of the suggested uses is "filling planters and making potting soil".

And to be precise, no, there is no such thing as 'composted peat moss'. 'Peat' is the partially decomposed remains of bog plant material - the moss - so a more accurate way of saying it is that peat is naturally composted sphagnum moss :-)

Right. But look at the picture of the stuff. It looks like sphagnum not peat.

garden gal, that brick is peat moss, but it is of the long fibrous variety (item on left in the photo), which is not to be used in the 5-1-1 mix.

Cedrick, coco, or coir is used by some but you should read this before you decide to use it: http://forums2.gardenweb.com/discussions/1385497/coir-for-peat-in-511
