The following pictures were taken from Horticulture 263, Non-circulating Hydroponic Methods, student projects. This innovative class uses "hands on" instruction to teach the art of noncirculating hydroponic methods.

Syllabus

Instructors:

  • Sheldon Furutani, Ph.D. (furutani@hawaii.edu) (CAB. 101A)
  • Bernie Kratky Ph.D. (UHM-Beaumont Experiment Station)

Meeting time: Friday 10:00am to 14:40pm or as appropriate.

Required text: Non-circulating hydroponic methods. 1996. B.A.Kratky. DPL Hawaii .

Meeting Place: CAB 201 or Panaewa Farm Laboratory Non-circulation hydroponic greenhouse.

Objective

To provide students hands on experience in the area of hydroponics. Practical experience in setting up a hydroponic system including: construction of a hydroponic growing system, nutrient formulation, calculation and monitoring, and data of crop growth will be emphasized. A final project report (a formal written report and oral presentation to the class) is required.

Format for project selection

  1. Will be selected upon mutual agreement with instructor. Project maybe a circulating (powered by a pump, etc)/ or a non-circulating (stagnant) hydroponic system. The project must test a comparison between 2 or more factors example salinity level, system, media etc.; test an idea or confirm an existing method. The results of the project will be used as the primary subject in the final project report.
  2. Each student shall work independently (only one student per project). Students are encouraged to selectmore then one project. Since a large part of the grading is based on the quality of the project, a second project would ensure increased success.
  3. Oral reports on project(s) construction and observed crop growth shall be arranged by the instructor (usually by mid-term).
  4. ***Remember - crops need time to grow - start your project early as possible.
  5. You are encouraged to purchase your own supplies if you wish to take your project home.

Grading

All project must be taken down and stored at the end of the semester. An "Incomplete" grade will be issued if a project is not taken down and cleaned-up.
