About this file
This document is a specification for walk-in plant growth chambers required by the United States Department of Agriculture (USDA) Agricultural Research Service (ARS) Pacific West Area located in Hilo, Hawaii.
The key requirements include a 144 sq ft growth chamber with controlled vertical and horizontal airflow, an air-cooled refrigeration system designed for the Hilo climate, and integrated data monitoring and alarm systems. The chambers must provide lighting intensity of 1,000 micromoles/m2/s in single tier mode and 600 micromoles/m2/s in multi-tier, with LED broad spectrum and supplemental far-red lights. Temperature range is 10-35°C with 0.5°C control, and humidity up to 70% RH with dehumidification capability. The chambers require full installation, a 3-year warranty, and an annual preventative maintenance program. The USDA is procuring two of these growth chambers through a Request for Quotation (RFQ) solicitation under a Small Business set-aside, with a due date of August 22, 2024.

Item Specification
• General o Walk in growth chamber, made with material that is smooth and impervious to liquids and can be cleaned and disinfected.
o 144 sq ft of growing area that can accommodate different heights of plants from 20’ to 72”.
o Air flow in chamber should be able to be switched from controlled vertical airflow for single tier growth mode, to horizontal airflow in the multi-tier configuration.
o Air-cooled system refrigeration and specifically be designed using Ashrae 20-year extreme guidance for Hilo.
o Multiple growth chambers will be connected by vestibule/anteroom which is sealed and prevents contents from growth chamber being directly released into the building.
o External air exhaust will be passed through HEPA filter.
o Room should be secured for potential seismic activity.
• Controller o Should be programmable on daily schedule o Data should be able to be viewed locally at chamber and downloaded for record keeping.
o Alarms should allow for local monitoring and through internet or other system to allow for alerts.
• Lighting o Provide lighting intensity of 1000 micromoles/m²/s in single tier configuration and 600 micromoles/m²/s in two or three tier configuration.
o Intensity should be able to be controlled for different light requirements, automatic dimming capability should be combined with specific R/FR manipulation using separate 730nm sources.
o Lights should be LED broad spectrum with supplemental far-red light.
o Lights should be monitored and available on data display.
• Temperature o Chamber shall operate between 10°C to 35°C lights OFF, 15°C to 35°C ON with ±0.5°C at the control point.
o Provide a programmable min and max temperature or a limit tracking alarm that automatically follows the programmed set point o Provide an independent factory-set high and low temperature limit.
o Sensors are located in a self-contained portable aspirator. This allows accurate measuring and recording by sensing at plant location.
o Adjustable fan speed.
• Humidity mailto:Tracie.Matsumoto@usda.gov o Provide additive humidity function achieving up to 70% RH lights OFF/ON, limited by a 25°C maximum dew point.
o Ensure humidity control of ±3% RH and incorporate a dry humidity sensor to directly measure humidity in %RH.
o Provide dehumidification using mechanical means to achieve a desiccation rate of 6 pounds/hour of moisture at minimum.
• Supplement Carbon Dioxide o Provide additive C02 control including all necessary sensors, control valves, and injection system for additive CO2
• Installation o Vendor shall include full installation of equipment and components at project site.
o Full installation and commissioning shall be completed by vendor within eight weeks of mobilizing to site.
• Warranty o Vendor shall provide a full three-year warranty on all equipment including parts and labor.
