Most of the orchids we cultivate originate from cloud forest regions, both in the old world and the new; they are therefore very much at home in a high humidity. Many of the tropical orchids need a saturated atmosphere in which to thrive.
It should be placed near the floor, below the plants, to allow the cool vapour to reach the plants standing above. Within a few weeks of introducing a humidifex into the greenhouse or home you should see a noticeable increase in aerial root activity on your orchids.
This material can be fixed in the same way as polythene, but because it is full of minute holes it is able to breathe which prevents condensation and drip. Neither does it cut too much light from the plants. The netting is easily obtainable from garden centres. It can be taken down in summer and stored for the following winter. As it does not tear easily, it should last for several seasons.
There are two main areas where insulation can be beneficial. One is below the staging level where the greenhouse is built on brick or wooden foundations. This whole area can be lined with polystyrene, polythene or other insulation boards which will withstand the moisture and humidity. Insulating the door and ventilators with any of the proprietary brands of polythene on the market is a necessary step to keep out draughts. If double glazing with glass is used this mould have been allowed for in the original construction of the henhouse.
The little plants cannot be knocked off, and the compost will dry out less quickly. Providing that sufficient fall is put on the shelving, there is no danger of excess water collecting in the gutter. As the surplus water will run out of the end it will not harm the plants on the shelf below. Plants housed in this way usually do extremely well as they are easily looked after and there is no danger of the one at the back' being missed at watering time.
Either north or south ends of the house are suitable, or the guttering can run the full length of the greenhouse at about eye level. Place two thin strips of wood or plastic in the base of the guttering, to raise the pots slightly from the floor and allow a clear run of the surplus water, thus preventing puddles resulting in the plants being saturated.
