    I've had wildly fluctuating peat quality. Some of it LOOKS like it needs washing, and leaves a slimy muck, and some brands look perfect right out of the bag. I wash it all just to be on the safe side, but take extra care with the lower quality stuff, and just use the "floater" peat. Oh, I microwave, too.

    I microwave peat, but I have never washed it. I have been washing perlite, which the ICPS page suggests, but I have never bought other than horticultural perlite, so maybe that is not necessary.
    I sort of came to Tamlin's conclusion on adding milled sphagnum to the peat/sand combo, as our silica sand is very fine(what I have found), but it comes in 50# bags pre-washed.
    I guess if you use perlite and you don't want it to turn green, you can always vover the surface with something(like a thin layer of fine orchid bark, or LFS, ect).
    I find myself delaying planting dangerously at times, because I am starting to worry about washing and soaking EVERYTHING!!! [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/mad.gif[/img]

    I forgot. How much of a % of peat is "floater?" I mean for aqautic Utrics, aren't you suspposed to throw some peat in the water and when it sinks, put your plants in?

    I`ve found a mere 10-20% will be floater peat So the floater peat goes to the more delicate species and the sinker peat goes to the "tougher" ones. By delicate I mean as far as there soils go such as Drosera. I have found non washed peat formms a black hard crust on the surface of the plants pot and Drosera especially seem to dislike this.

    Algae loves microwaved peat. At least at the equator where I lived. I wanted to kill off microorganism in the peat but ended up having to scrape off algae before the young seedlings can establish themselves. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/confused.gif[/img]

    Just a side note, perlite is IDEAL for my pings. No perlite, no pings. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    Whats the difference between floater, and sinker peat? (by that, i mean what makes it float and what makes it sink) I soak my peat but never rinse it.. logically rinsing with water (which has a neutral pH) would raise the pH of the peat. Maybe the slightly less acidic pH of the soil helped your plants grow faster? I think it looks kinda cool when my perlite gets algea, especially when its mixed with sphagnum... looks more natural than white spots in your soil [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]

    Hmmm. good question,it seems the less decomposed(and therefore more sphagnum like) peat is what floats while the finer sludgeyes stuff sinks.

    Hmm, I honestly never washed or microwaved my peat or any media. Is this really a problem? I use peat packed in a large chunk and it looks like dust (not the best peat) and it seems to work fine. Zongyi
