For the majority of my plants, I use 30mm or 40mm terra cotta pots.  They are commonly called "thumb pots" or 'fairy garden pots". I use them for a few reasons:

1. Since most of the species I grow are true miniatures, 2-in pots are too big.  Most miniature species will rot in 2-in pots, especially plastic pots.

2. Mounted plants can dry out too quickly.

3. Terra cotta helps keep the humidity up, and as it dries, it keeps the roots cool.

For my larger plants, I use clear net pots. I would prefer to use terra cotta pots, but the larger pots are too heavy, especially when filled with wet sphagnum moss. The clear net pots are harder to find, but they look better than black net pots.

For my mounted plants (typically plants with fleshy roots or very large Pleurothallis species), I use cedar mounts. I buy them premade from Andy's Orchids. 

I use Spagmoss from besgrow. Since I live in a condo in the city, the compressed mats of sphagnum are easy to store. I use the 100g portion.

I fertilize once per week with Miracle-Gro Bloom Booster. (1/4 tsp. per gallon)
