How to get orchids to grow huge?

my mom lovesss orchids and that's not an over statement. how can she get them to grow to be HUGE!!!

Hi,

The ideal place in the home for growing orchids is a bright window, free from drafts, where your plants receive indirect sunlight both morning and afternoon. (A south window is best.) In winter, give orchids all the light possible

Mist your plants with distilled water because tap water can lead to salt deposits on the leaves. A plant which is kept soaking wet invites attack by bacteria and fungal diseases. If you are able to enclose an area like a greenhouse, you will find it easier to maintain a proper humidity.

Watering is the most important factor in orchid culture. A good rule of thumb is to water whenever the medium (osmunda fiber or bark mix) is dry. If you grow the plants in pots suspended in the air, they will dry out more rapidly than bench grown plants and will need watering more frequently.

Hope that helps!
