Commercial germination chamber with all-stainless-steel construction. A germination chamber is standard equipment for any business that grows plants. By creating a consistently warm, humid environment, the chamber takes the risk out of seed germination and is designed to achieve a 100% germination rate for viable seed.
Holds 60 Winstrip or 1020 trays. With 200-cell trays, that is up to 12,000 starts.
Shelves can also accommodate Paperpot Germination Trays.
Accessories
- Germination Chamber Cooling Kit — automatically brings in cooler air on warmer days to help control chamber temperature.
- Germination Chamber Curtains — helps block direct sunlight, reduce unwanted heat gain, and provide darkness when needed for germination.

A germination chamber heats water to create warm, humid conditions. It cannot cool below the surrounding temperature, so keep it in a shaded location below its 75°F setting to allow the heater to operate properly.

Standard Features
Polycarbonate Doors
Shatterproof doors are built to withstand the rigors of the farm. They are ultra-clear and full-length so you can easily monitor your starts. Some seeds also need light to germinate. The cabinet has double doors on both sides.
Magnetic Closure
No pesky clasps or latches to deal with. Doors open and close easily and are held in place by rare earth magnets.
Adjustable Top Vent
The screened top vent can be adjusted to increase or reduce the amount of moisture in the chamber. Screen is stainless steel.
Full-Length Stainless Hinge
The hinge extends from the top of the chamber to the bottom. These doors are opened and closed many times a day throughout the season, so they are built for repeated use.
Expanded Shelves
The stainless-steel expanded shelves will not droop or rust. The open design allows steam to circulate evenly throughout the chamber. Shelves are easily removed for taller plants, such as during tomato graft healing.
Stainless Reservoir
The large water tank allows multiple days of steam without the autofill engaged, which is useful for farms with limited water. It is fitted with a low-water-level shutoff to protect the heating element.
Large Casters
Fitted standard with large 8" rubber locking castors. One can easily move the unit when needed.
GFCI Plug
Comes standard with a heavy-duty cord and GFCI plug.
Digital Thermostat
A professional precision digital thermostat controls heating and cooling, all contained in a waterproof housing.

Perfect Combination
Winstrip Trays
The open cell design is perfect for germination chambers as it allows even distribution of steam around the chamber.
Chamber Tips
Advice on Best Practices
1
Dibble and Seed
Dibble all trays before seeding. Either use your finger or a dibble board. This will center your seeds in the cell and provide a good environment for germination.

2
No Covering Seeds
Leave seeds uncovered so you can easily monitor germination. Covering seeds is unnecessary in the chamber.
3
Soak Tray
Thoroughly water the tray before putting into the chamber. Tray will not need watering again until it is removed.
4
Temperature
An ideal temperature for most vegetable and flower seeds is 75–78°F. The thermostat is preset by us, so there is no need to change it.
5
Take Out
Remove tray when 50% or more seeds are visibly germinated. This is to prevent legginess if left in the chamber too long. Check your chamber daily.
Problems with Heat Mats
Heating mats or heated tables dry out the soil which will kill the seed unless you constantly water. This is not only extra work, but watering will cool down the seed and delay and reduce the germination rate.
Great Option
Shade Curtains
To maintain moisture in the chamber and steady temperatures, direct sunlight into the chamber should be avoided. The sun will heat up the chamber. Curtains help to eliminate that issue. They are also great for some flower seeds that require darkness to germinate.
3/8" stainless steel rod and aluminum clips. The cloth is 55% shading which can be bunched for greater blocking. Easy open and close.
Cool Crops
Spinach and Lettuce
These cool-temperature crops germinate well at 75°F, which is the recommended chamber setting for most vegetables and flowers.
Germination rates can decline when the temperature exceeds 75°F.
We recommend the optional fans and shade cloth to maintain a consistent temperature in late spring and summer.
Thermostat
Best in Class
A standard feature is the RANCO Two Stage Digital Thermostat in a NEMA 4 enclosure. It provides precise temperature control with an adjustable differential as small as 1°F.
Thermostat operating range: -20°F to 140°F.
For best temperature control, the optional curtains and automatic fans are recommended.
Normal chamber operating temperatures can range from the shaded room temperature to over 95°F.
An ideal setting for germinating most vegetable and flower seeds is 75–78°F.
Option
Automatic Fans
Fans pull in cooler air to help the temperature not rise on warmer days. This enables you to keep steam being produced and continue to achieve great germination with cool season crops
Fans are tied into the thermostat and will come on automatically.
