Greenhouse Operations Hemp Policy

  1. The Principal Investigators of projects that involve growing hemp in greenhouses are pursuant to requirements set forth under state and federal law and OSU policy. OSU Greenhouse Operations (GOPS) users therefore need to contact the Global Hemp Innovation Center (GHIC) at to acquire approval prior to growing hemp within the OSU greenhouses.  
  2. Research projects should be on record in the OSU GHIC Hemp Registry database. Fill out the form at the following link and describe the specific section within the greenhouse: GHIC will keep on file OSU’s single campus-wide ODA Grower License and provide a copy to OSU Greenhouse Operations (GOPS).
  3. It is understood that the Principal Investigator assumes 100% responsibility for compliance with all federal, state, and OSU laws, rules, and regulations for growing and handling hemp within the OSU Greenhouses. This includes documenting that each staff member has reviewed the OSU GOPS Hemp Policy & Guidelines and the OSU Guidelines for Cannabis Research: .

 All other guidelines for using the OSU Greenhouses for hemp research are the same as those for all other greenhouse users.

  1. The following items are required information for successful greenhouse projects. Contact GOPS at 541-737-2381 or to give this information to the GOPS staff.
  1. Desired environmental temperatures for day and night
  2. Pest management – thresholds, biocontrol use, and any special needs
  3. Watering requests
  4. Supplemental lighting requests
  5. Other requests or need for cultural recommendations
  1. All hemp material must be disposed of according to federal and state law and OSU guidelines as well as the GOPS Hemp Policy. The steps for disposal are as follows:
    1. Follow the OSU EHS hemp disposal guideline: .  To prepare plant material, remove and bag vegetative material from the rootball. Either the user or GOPS can submit the waste pickup request to EHS.
    2. Hemp rootballs need to be placed in the designated locked dumpster at West Greenhouse. Coordinate with GOPS to access to this dumpster.
  2. All hemp researchers and staff need to be aware and considerate of other user groups who share the greenhouses. This includes the following topics:
  1. Security – locked doors, visibility, and other concerns
  2. Odor – hemp odor may permeate other areas of the greenhouse
  3. Pollen transfer – hemp pollen may intrude on other hemp projects and outside the confines of OSU GOPS space
  4. Keep aisles clear of plant material for ease of watering, avoidance of skin irritation, and to minimize odor permeating clothing
  5. No hemp should remain on corridor benches or outdoors – hemp should remain only within a secure registered greenhouse section
  1. Drying of hemp within a greenhouse section must have prior approval from GOPS.
  2. Any modifications to the greenhouse structure and/or specialized equipment must have prior approval from the GOPS Manager. The project initiating any changes is responsible for all cost associated with the modifications or equipment.
