Vanda in a Pot, culture

I live in an apartment condominium in Northern Virginia. When I got interested in orchids I realized I had a desirable true east exposure from the windows. I fortunately also had 6 inch deep window sills. The apartment also has a whole house humidifier that runs at about 40+% humidity full-time during the heating season. Direct downdraft from the heater/air conditioning vents has been diverted so as not to strike the orchids. The few orchids with which I began seemed to thrive. Then one day my wife and I were at the National Capital Orchid Society show and she was captivated by a large, dark blue flower that we discovered was called a Vanda. On further research it seemed these orchids were particularly fussy in their cultural requirements. I read that most are grown bare root in hanging baskets, often outdoors in places like southern Florida. That the roots required frequent watering or misting. That they would not tolerate being too wet, nor too dry but demanded relatively high humidity. The also preferred bright indirect light but preferred only short periods of direct sunlight. These did not seem to be conditions easily met in a relatively small condominium where the growing spaces also doubled as bedrooms.

Being at a stage in life where I can afford to experiment, I decided to try to adjust the plants purported fussiness to the realities of my environment.

The first thing that had to go was the idea of a hanging basket. It had to grow in a pot and that had to be of modest dimensions.

Next it could not require too frequent watering. Orchids are my joy not my masters. I decided it probably would not like usual bark mixtures since they held too much moisture. Being willing to be avant-garde I decided to try EpiWeb imported by First Rays Orchids (Welcome to First Rays Orchids) from Scandinavia. It is a firm foam-like plastic material made from recycled milk containers. It holds no water except what might get trapped in the tiny spaces in the foam. It is available in sheets for mounting but also in 1 inch cubes which was what I used. This material seemed adequate to support the roots and plant but I needed something to retain some moisture to fulfill the criteria of not requiring daily attendance. Again from Rays I decided to add in PrimeAgra which is a Light Expanded Clay Aggregate (LECA) of which there are several similar on the market. This product remains moist after soaking and is often used in semi-hydroponics culture. I mixed this about 3 to 1 of EpiWeb to PrimeAgra.

The lucky plant was a Pakchong Blue purchased mail order from Hausserman
