Seed germination
chamber controller
Seed companies, nurseries and seed testing labs need germination conditions they can repeat. The RD150 holds temperature and humidity setpoints in a chamber and runs timed cycles, such as alternating day and night temperatures, from stored programmes.
THE PROBLEM
Germination results are only useful if the conditions were repeatable
A nursery germinating vegetable seed for transplants wants an even, fast emergence across every tray. A seed company running germination tests wants the same seed lot to give the same result next month. Both depend on temperature and humidity holding to a setpoint, and many seeds respond to an alternating temperature cycle between day and night.
Chamber builders often assemble these from a temperature controller, a humidity controller and a cyclic timer. Each change of programme means reconfiguring three devices, and the record of what the chamber did lives on a chart recorder or nowhere.
HOW WE SET IT UP
Repeatable germination conditions
Setpoints and cycles together
Temperature and humidity setpoints run against timed cycles in the same controller. An alternating day and night regime is one programme, so the chamber switches on time every day.
A programme per seed type
Different crops need different conditions. The RD150 stores multiple recipes, so the chamber can move from tomato to onion to a grass seed test without re-setting instruments.
Adapted to your chamber
We adapt the RD150 to the heating, humidity and timing hardware in your chamber design, and size the outputs to the heaters and humidifiers you use.
Run records you can file
Connected units send setpoints and measured conditions to RIOD Live or your server. Each run can be exported as a PDF or Excel record with an audit trail, alongside the germination count.

FAQ
Questions buyers ask us
Can a germination chamber controller run alternating day and night temperatures?
Yes. The RD150 runs temperature and humidity setpoints against timed cycles, so an alternating regime is set once as a programme and repeats automatically.
Can we use the RD150 in a chamber for official seed testing?
Chambers used for formal seed testing need validation against the method the lab follows, for example ISTA rules or a national standard. We plan that validation into the project and carry out certification work to your target standard.
How many seed programmes can be stored?
The RD150 stores multiple recipes with their own temperature, humidity and timing. We size the list to the crops and test methods you run.
We build germination chambers. Can we buy the controller under our brand?
Yes. We build the RD150 to your order with your logo or labels from 100 units. Licensed technology transfer is also available if you want to make the controller in your own facility.
