I haven't really seen much difference in either, I think they both work quite well

50/peat - 40/verm - 10/coir (ph adjusted peat - of course)

Agar, what brand of pH adjusted peat do you use? Do you include pH buffers in this mix?

No brand of bulk peat I am aware has the ph adjusted. You have to do it - yourself. A ph test meter probe can be had for a few bucks at Lowes, HomeDepot & other stores with garden centers.
I use oyster shell flour to adjust the ph.

Wait, some of the teks say to use Hydrated lime/Calcium Carbonate AND Oyster shell... so Ive been holding off on making a 50/50+ casing of Verm/Peat/Oyster because I cant find the other junk anywhere. Are you saying I can start sterilizing my casing mix today? I dont need the Hydrated Lime stuff?

do you need to adjust ph levels for coco coir?

Im pretty sure coco coir is PH neutral

Its not required, but I've noticed a difference in later flushes with coir that had some eggshell thrown in the mix. Mycelium piss'll make the casing slightly acidic, so a ph adjustment helps out a little in this sense... gl bro

pH of Coir:
pH adjusted peat is NOT hard to find, just get Sphagnum the pH is exactly 7.

Yoo....Kron
Please be advised that PH of peat can differ dramaticly from one type & source of peat, to another. As such, it is ALWAYS wise to test the PH, prior to use (and, adjust if needed). Just like all money isn't the same color. It depends on where it came from.
Peats come in three major types: moss peat, reed sedge, and peat humus.
Moss peat, usually referred to as "peat moss," is the least decomposed of the three types. It consists of visible fibers of sphagnum, hypnum, and other mosses. Moss peat is lightweight, acidic (pH 3 to 7) and varies in color from yellowish to dark-brown. Its high moisture-holding capacity (approximately 15 times its dry weight) makes it a good soil amendment, or component of potting soil.
Sphagnum and hypnum moss peats differ slightly in their physical characteristics. Hypnum peat decomposes more rapidly, has a higher pH (5 to 7), and re-wets more easily than sphagnum peat. Sphagnum peat develops surface waxes upon drying that make them difficult to re-wet. Sphagnum peat is regarded as superior over hypnum peat for soil amending and as a growing media. The low pH of sphagnum peats (from 3 to 4.5) makes them better suited for use with acid-loving plants such as rhododendrons and blueberries.
Among the sphagnum peats, dark peats (those which are dark brown) are less elastic than lighter colored sphagnums. They will not return to their original volume after compression during packaging. Dark peats also lack the durability of lighter colored sphagnum peats; consequently, they are not as well suited to long-term culture.
Reed sedge peats consist of the remains of reeds, sedges, grasses, and other marsh plants. This type of peat varies considerably in composition and in color (reddish-brown to almost black). Its pH ranges from 4 to 7.5, and its water-holding capacity is less than moss peats (about 10 times the dry weight). Reed sedge peat is finer textured than peat moss. It is not as good a growing medium, but it is useful as a soil conditioner in the garden and in potting soil mixes.
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.
Woody peat, although not individually cited in the U.S.B.M. classification, can be purchased separately or as a component of peat humus. Woody peat results from the breakdown of trees, shrubs, and undergrowth from the forest floor. These peats vary greatly in texture, but they are usually quite porous. Woody peats are dark colored and acidic (pH 3.6 to 5.5). They decompose rapidly to become peat humus.
Mixtures of some of the above peat types will be encountered. Under the Federal Trade Commission regulations, a content of only 75 percent peat is sufficient to warrant the use of the term "peat". The best peat mosses contain 95 to 99 percent organic matter. A first-rate reed sedge peat will be 85 to 95 percent pure.

probably the reason why i thought my ph meter didn't work
