Soil Mix Round-Up

Not a Comprehensive List, but Still a Good Start.

Basic Recipe 1:
1  part peat moss
1  part composted bark

1  part compost

1  part sand

1  part perlite
If the mix clumps together and the compost you use is heavy, add more perlite to ensure good drainage. Use extra compost or bark when growing more mature plants, but don’t make it too rich for young plants—it could damage their delicate roots and stems.

Basic Recipe 2:
1 part compost
1 part coarse sand
1 part sphagnum peat moss
1 part composted pine bark
2 T. lime for each shovel of peat moss

This has the added distinction of being from a University Extension Site, and it is part of a whole Container Growing Guide to which I will surely return:
(RECIPE:) An acceptable soil based mix can be made by using one part garden soil, one part peat moss and one part perlite or coarse builders sand. Don't use fine beach sand or play sand.....
(SOIL-BASED VS SOILLESS:) Soil-based medias are also a bit more forgiving when it comes to water and fertility. They tend not to dry out as fast, and they also tend to hold on to nutrients longer. Because soilless medias can be a bit more costly, you could mix 25 percent soil with the soilless media to stretch your soilless media for a few more pots...
(“TOP SOIL”) There are also bagged products labeled as top soil that tend to be largely sedge peat. While they are inexpensive and look very good, once put into a pot they are poorly drained and poorly aerated. They can be used in combination with soilless media products or amended much the same way as if you were using garden soil....
(FILLERS:) To reduce the cost and also the weight of the container consider adding "filler" to the bottom of the container to take up space. Many things can be used, but they should be something that is inert, able to take up space and not break down over the course of the growing season. While there are inserts made for this purpose, there are a lot of home products that can be recycled for this use.
Items such as crushed aluminum cans, plastic milk jugs, and non-biodegradable "packing peanuts" are usually readily available. Fill the bottom one-quarter to one-third of the container with your choice of material. Lay a piece of landscape fabric over the top of the material and fill the rest of the container with media. The filler takes up space the landscape fabric keeps the soil from infiltrating the filler while allowing water to pass through, and there is still ample space for roots to grow.

Quick Items I Gleaned from ASCFG Bulletin Boards:
SunGro's Metromix
I'd recommend Fafard #2. I recently purchased a few bags of MetroMix 360 to try and found it to have too many fines. I mixed it with Fafard 51L to add air space.

Recipe Taken from the Metromix Website itself (hence no ratios beyond the bark - though maybe if I can find an actual picture of the bag it'll be on there?):
60-70% Bark*
Canadian Sphagnum Peat Moss
Horticultural grade Perlite
Starter Nutrient Charge
Dolomitic Limestone and a Wetting Agent

*Product will consist of Composted Pine Bark in the Eastern and Central regions. Product will consist of Composted Fir Bark in the Western region.
