Greenhouse Temperatures

Many people ask us what temperatures we grow our orchids at and what sort of plants we keep in which section, so I thought I would let you all know.

Warm Asia

Warm Asia is the hottest of our greenhouses, with a temperature zone from 20 – 33 degrees C, and our vents open at 26 degrees. It is home to mainly Dendrobiums, Vandas, and Paphiopedilums.

Warm America

Warm America has a temperature zone from 18 – 33 degrees C, and our vents open at 25 degrees. It is home to mainly Prosthecheas, Cattleyas, and Stanhopeas.

Cool America

Cool America has a temperature zone from 12 – 28 degrees C, and our vents open at 22 degrees. It is home to mainly Masdevallias, Oncidiums, and Laellias.

Cool Asia

Cool Asia has a temperature zone from 10 – 28 degrees C, and our vents open at 17 degrees. It is home to mainly Coelogynes, Dendrobiums, and Cymbidiums.

Temperate sub-tropical

Temperate Sub-Tropical is out coolest section with a temperature zone from 4 – 26 degrees C, and our vents open at 7 degrees. It is home to mainly Pleiones and Disas.

The Micro-propagation Lab

The micro-propagation lab is kept around 23 degrees C, and is home to all of the orchids in flack. We grow a lot of orchids from seed so our lab is very full as you can see from this picture.

The classroom

In the middle of the greenhouses is a classroom which is used in many ways. It is used for classes to come and learn the techniques of micro-propagation of orchids. Also it is the main base of greenhouse club. It is where we all meet at lunch time and after school.

Temprate/sub tropical

The section of the greenhouses we call Temperate/sub tropical has turned flat! By which I mean that there is very little plant action above the compost. We keep a minimum of just 4 degrees celcius in this part of the greenhouse so most of the plants lose their leaves in the winter and come back in the spring. The newly repotted Pleiones are just beginning to show above the compost and the Stenoglottis are sprouting their new growths so it wont be long before this section is full of leaves and flowers again.

Orchid propagation the curriculum

Year 10s hard at work sowing orchid seed

Year 10 students at Writhlington have the challenge of sowing orchid seed in aseptic conditions. In this part of the OCR nationals course students must demonstrate the ability to work safely and maintain aseptic conditions for the orchid seed they sow on a nutrient agar. This year the seed is Stanhopea tigrina, a fantastic species from Central America, and these girls are hoping that their work is a success and they have some plants to take home by the time they get their GCSE reults.
