The first would be for the cool-growing ...

The first would be for the cool-growing orchids like Cymbidiums, some Cypripediums, and Odontoglossums, and would be kept at a minimum winter temperature of 48 degrees F. at night.

The second, which might be called the intermediate house, would be kept at 60 to 65 degrees, a temperature suitable for Cattleya and allied genera.

The third, or hothouse proper, would have a minimum night winter temperature of from 68ø to 700, making it suitable for Phalaenopsis, Vandas, Dendrobiums, and the mottled-leaf slippers like Cypripedium Maudiae.

Most amateurs, however, lack space and resources for three houses, and with ingenuity one house can be departmentalized.

A section away from the source of heat and infrequently pene trated by the sun should be selected for the orchids preferring coolness.

One bench might be left without piping for this purpose.

Warmer-growing plants can be placed in the warmest part of the greenhouse.

Plants requiring direct sun, like Laelias and Cattleya gigas, can be placed right up against the glass.
