Our Fitotron® Standard Growth Rooms (SGRs/SGRFlex) have been specifically designed for user flexibility in size and application, providing an adaptable growth area suitable for any future changes of research needs.

Fitotron® SGRs/SGRFlex are available in 21 external sizes dependent upon user requirements, with growth areas ranging from 1.2m2 to 24.5m2. SGRs/SGRFlex are available as either single or double-sided with up to three growing areas per side. Our rooms can be fitted with one fixed tier of lighting and up to three tiers of moveable lighting.

SGR’s are available with growth areas from 1.2m2 to 24.5m2 and with lighting up to 700 µmol m-2s-1 plus full humidity control. Alternatively, we can design and build to suit individual requirements.

The standard modular concept offers unsurpassed accuracy and reliability in the control of temperature, humidity and lighting. We use state-of-the-art programmer technology and energy-efficient lighting systems, providing unequalled reliability and durability. This sustainable design offers the end-user a cost-effective solution.

Our combination of high quality components, design, and manufacturing expertise enables Weiss Technik UK to offer outstanding control performance and assurance of the integrity of the results of temperature, humidity, light and atmospheric testing. Our policy of continual liaison with leading researchers ensures we maintain our premier position as suppliers of high quality plant growth and associated facilities.


The Fitotron® Economy Growth Rooms – fluorescent version (EGR-FL) and Metal Halide version (EGR- MH) have been designed as a cost effective option for when the primary objective is to grow large amounts of plant material in standard controlled conditions. EGRs are easy to select and understand being offered in three sizes with multi levels of illuminated growing.

The FITOTRON® EGR ‘Walk-In’ Economy Growth Room enables the researcher to maintain controlled growing conditions of temperature and (optionally) humidity in a 24hr period with independent selection of photoperiods. A full range of ‘day/night’ cycles with ‘dawn/dusk’ effects can be programmed.

FITOTRON® Economy Growth Rooms are specifically designed for growing large amounts of plants to various growing heights which require moderate light levels. EGR rooms are ideal for arabidopsis plants from seedling to maturity. Weiss Technik UK is a world leader in the design, manufacture, installation and service of controlled environment equipment for plant growth research. Building on over 40 years’ experience, our plant growth equipment incorporates the latest developments in technology, many having been originated by the company’s own design team.
