Professional germination chamber with all-stainless-steel construction, sized for the avid hobby gardener. A germination chamber is standard equipment for anyone serious about growing 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 eight Winstrip or 1020 trays. With 288-cell trays, that is up to 2,304 starts. It also holds four Stack and Nest Paperpot Trays.

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
All Stainless Construction
This is professional-grade equipment built for long service life and sized for the avid gardener.
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.
Magnetic Closure
No pesky clasps or latches to deal with. Doors open and close easily and are held in place by rare earth magnets.
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.
Polycarbonate Doors
Shatterproof doors are built for long service life. They are ultra-clear so you can easily monitor your starts.
Digital Thermostat
A professional precision digital thermostat controls heating and cooling, all contained in a waterproof housing.
Full-Length Stainless Hinge
The hinge extends from the top of the chamber to the bottom. The door is opened and closed many times a day throughout the season, so it is built for repeated use.
Stainless Reservoir
The large water tank allows multiple days of steam and is fitted with a low-water-level shutoff to protect the heating element.
Working Lights
Large LED lights to let you know when your chamber is calling for and providing steam.

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 to germinate.

2
No Covering Soil
Leave seeds uncovered so you can easily monitor germination. Covering seeds is unnecessary in the chamber.
3
Soak Tray
Thoroughly water the tray before placing it in the chamber. The tray should 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 chamber too long.
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 resulting in delayed and reduced germination rate.
Cooler 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 shading the chamber or moving it out of direct sunlight to prevent that from happening.
Thermostat
Best in Class
A standard feature is the RANCO Single 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.
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.
Grafted Tomatoes
Germination Chambers make the best healing chamber for grafted crops.
