Reach-In Plant Growth Chambers

Reach-In Plant Growth Chambers for Replicated Experiments

A reach-in plant growth chamber is a self-contained, programmable cabinet in which temperature, light and, on suitable models, humidity and CO₂ are controlled for the plants or cultures inside. Every tier shares the same set conditions, so reach-in chambers suit replicated experiments where treatments must be compared like for like.

JKG supplies multi-tier reach-in chambers from the JKG Universal Series (JKG-41 and JKG-66), manufactured for JKG by Percival, and the full Percival range in 22, 30, 36, 41, 66 and larger cabinet sizes: SciWhite and SciBrite LED plant growth, Arabidopsis, algae, low-temperature, tissue culture, dew formation, seed germination, incubator, Drosophila, CO₂ and stability chambers.

Hydroponic NFT option

A nutrient film technique (NFT) system available on the LED-41L2 (SciBrite) and E-41L2 (SciWhite) plant growth chambers. It is designed for leafy greens and herbs with short growth periods and small root systems, and suits studies of nutrient delivery, root architecture, stress response and water-use efficiency.

Model	Tiers	Light (µmol/m²/s)	Temperature (°C)	Volume (m³)	Shelf area (m²)	Max. height (cm)	Exterior W × D × H (cm)
LED-41L2	2	1,550	10–44 ± 0.5	1.1	1.3	54.9	104.1 × 85.4 × 196.1

Buying guide

How to Choose a Reach-In Plant Growth Chamber

Six points decide most reach-in specifications. Settle them before you compare quotations or write tender specifications.

Tiers versus height and light

A single tier gives the most growing height and the highest intensity; three or four tiers give more shelf area for shorter plants. On the JKG-66, one tier gives 120 cm of height and three tiers give 35.6 cm.

SciWhite or SciBrite LED

SciWhite LED suits general plant growth. SciBrite LED adds independent control of blue, red, white and far-red for light-quality and photomorphogenesis studies. See specialized lighting.

Temperature at both ends

Check the lowest set point with lights on. Lit plant growth chambers start at 7 or 10 °C, non-lighted incubators at 2 °C, and low-temperature chambers at −10 °C.

Humidity and CO₂

Additive humidity (40–85%, 15–30 °C, lights off) and CO₂ control are options on suitable models. Humidity needs a demineralised water supply.

Programming and monitoring

The IntellusUltra controller runs day–night programmes and ramps. IntellusUltra Connect adds remote monitoring and alarms; WeatherEze software recreates recorded climate data.

Room and site

Allow about 20 cm clearance on the right and back, and keep the room near 24 °C and 50% RH. We confirm power and site needs before delivery.

Reach-In Chamber or Walk-In Room?

Most groups start with reach-in chambers. This is how the two formats compare.

Consideration	Reach-in chamber	Walk-in growth room
Scale	Replicated experiments with pots, trays or vessels on shelves	Large plant numbers, tall plants, several researchers working inside
Layout	Self-contained cabinet that sits in a laboratory	Room-size structure built to your floor plan
Growing height	Up to 123.4 cm (JKG-41L1E) or 174.5 cm (PGC-20)	Up to 238.8 cm (PR-106)
Growth area	Up to 2.8 m² (JKG-66L3E) or 5.1 m² (AR-100L3)	4 to 23 m² in standard configurations
Site work	Floor space, power and clearance	Space, power, heat rejection, water and drainage

FAQ

Frequently Asked Questions

Answers to the questions we hear most. Can’t find what you need? Our team will help.

What is the difference between the JKG-41 and the JKG-66?

Both are multi-application chambers in the JKG Universal Series, manufactured for JKG by Percival. The JKG-41 has an interior volume of 1.1 m³ and is offered in E, PG, AR, AL, I, NL, LL and VL series. The JKG-66 has 1.8 m³ and is offered in E, AR, GR, NL, LL and VL series. See JKG-41 and JKG-66.

What do the model numbers 30, 36, 41 and 66 mean?

They indicate the cabinet size. 30-series chambers are compact (0.3 m³), 36-series are 0.8 m³, 41-series 1.1 m³ and 66-series 1.8 m³ two-door cabinets. The letter prefix gives the application, such as E (SciWhite plant growth), LED (SciBrite), AR (Arabidopsis), AL (algae), CU (tissue culture), GR (germination) and I (incubator).
