  • Ventilation in Greenhouses and High Tunnels
    I had the pleasure of facilitating a workshop at the 2019 NOFA-MA Summer Conference about Ventilation in Greenhouses and High Tunnels. It provided an opportunity to collect information from various sources, ground truth observations with growers, and to revisit some fundamentals. The big takeaway, for me, is that there are many, many ways to ventilate […]

  • Improved Ventilation for High Tunnels
    I have received many inquiries about how to improve ventilation of high tunnels from growers with tunnels that have only roll-up sides. The issues they are facing tend to be either high temp, high humidity or both, leading to plant stress or disease. These situations tend to be in less than ideal sites for ventilation […]
  • Rats (and other rodents)
    Download the PDF version of this page here! When considering storage rooms, wash and pack sheds with growers there is one topic that is sure to strike a nerve: RODENTS. This document is intended to provide summary information about measures you can take to reduce crop losses from these pests.  It is the result of […]
  • Pumps and Pipes

  • Thermostats for Agriculture
    I am often asked by growers and processors to recommend a thermostat for a greenhouse, cooler, or postharvest process use.  There are many to choose from and their specifications can be confusing. It is important to remember just what a thermostat does. It is essentially no different from the light switch on the wall with […]
  • Update on Heating Greenhouses with Biomass

  • Calculating Greenhouse and High Tunnel Heat Loss
    I am often asked by growers to help estimate what size heater is needed for a greenhouse or what minimum temperature their high tunnel will reach at a certain outside temperature.  Below are some tools to help you do this yourself.  I have presented them in a range of complexity depending on how much you […]
