Know about greenhouses

Learn how to manage a greenhouse

Learn to grow crops and nursery stock plants in a greenhouse, shade house or other protected situation.

This course not only provides a credit in ACS qualifications, accredited through IARC; but it also prepares you to sit for RHS modules and acquire credits in the RHS advanced certificate or diploma.

Course Content and Structure

The course comprises 10 lessons:

1. Structures For Protected Cropping
2. Environmental Control
3. Cladding Materials And Their Properties
4. Irrigation
5. Nursery Nutrition
6. Relationship Between Production Techniques And Horticultural Practices
7. Horticultural Management In A Greenhouse: Pests And Diseases
8. Harvest & Post Harvest Technology
9. Greenhouse Plants
10. Risk Assessment

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

Duration: 100 hours

  • Describe the production of a range of crops
  • State the optimum stage of growth for harvesting a range of crops
  • Describe the harvesting systems for protected crops
  • Explain how shelf life can be affected by pre and post harvesting treatment of the crop
  • State the factors to be considered when marketing crops
  • Evaluate alternative marketing outlets
  • Relate packaging & presentation to marketing
  • Assess benefits to the grower and customer, of grading a crop before marketing
  • Determine elements of risk in the practical operations associated with protected plant production. 
  • Identify safe working practices


Even if you live outside of the tropics, you can grow tropical plants with the aid of structures that alter plant growing conditions. Greenhouses, shade houses, pergolas and conservatories are all useful structures for providing protection from weather extremes for tender plants. Such structures are commonly used to grow plants from the tropics and sub-tropics in cooler climate areas, or in areas where there is insufficient shade (e.g. growing rainforest understorey plants without the protection of upper storey plants).

For convenience in a cold climate, nothing beats a conservatory ‑ a glasshouse attached to the house, on the north or east side. A conservatory or greenhouses will allow you to:‑

Propagate new plants

    Grow tropical plants in cooler climates     Protect plants which are cold or frost sensitive over winter     Protect plants from wind, hail and pests
    Grow vegetables, cut flowers or berry fruits out of season, or faster than might be achieved outside.
