Garland Extra Large High Dome Propagator

Product Information

First, you will need to know how much your energy provider charges per kilowatt-hour. Let’s say they charge 14p per kWh (a relatively standard rate in the UK). Given that propagation can be a little hit and miss, having space in this large 52 x 42.5 x 28cm unit for so many seeds is one way to help increase the chances of success!

The Garland Fab4 Electric Heated Propagator is a great option for those requiring a little more warmth as it boosts the soil temperature by up to 10°C. It’s slightly warmer than others on the market, producing good results especially for seeds that require a hotter climate. Unlike others I’ve mentioned, there’s no need to place it in a sunny spot. The base features a fully enclosed and completely water proof heating element which gives an even spread of heat across the base with no hot or cold spots. Temperature is precisely controlled by the include thermostat which can be accurately set in 1 degree increments between 5 and 30 degrees celcius. Thanks to the seven separate cells, you can plant different types of seeds in each one if you wish, and each cell has its own vent to control the temperature according to the different plant.As I’ve already mentioned it’s the quality of this unit that really stands out. I love well built products and was impressed from the moment I unwrapped the first piece. Also, the cells can be prone to a condensation build up, even when the vents are open. I suppose though this is just what happens when you mildly heat something and contain it! Over time I’ve learnt that by switching the unit off and giving the cells a bit of breather everything clears up nicely. Electric propagators can range in wattage, and the size of the propagator will also affect how much power you need. The wattage determines the cost of running it.

Although this propagator doesn’t have a timer or thermostat, the growing conditions can be controlled to an extent using the air vents. It’s also incredibly simple to use, while the heat produced is even across the 7 trays. Measuring just 18.5cm wide, this propagator easily fits onto the average window ledge. The 76cm length means you can still fit ample seeds into this unit. The roof is high enough to allow seedlings to grow around 5cm, and the trays are also sufficiently deep to offer enough space for roots to fully develop. As a result, when it comes to planting seedlings out, they are already well established. This propagator comes with a power cord, although at 2m it may be a little short. Using it with an extension cable may be necessary.

Nutleys 60 Cell Full Size Seed Propagator Set - Tray: With Holes

To give an idea of size: there are units that are small enough to fit onto windowsills, whilst others will need to be placed on a table/worktop/greenhouse shelf. For example, in the above list, there are some seven-cell propagators, which would make it possible to plant around 21 seeds (if you planted three seeds in each cell). However, the good thing with individual-cell propagators like this is that you can have better control over the temperature in each cell. The number of compartments will allow you to grow several types of different types of seeds; you can adjust the soil type and environment to suit the individual seed. As I’ve already mentioned, this propagator is high performing, boosting the temperature by 8-10°C. The heat distributed is evenly spread across the base thanks to the reliable carbon fibre element, while the growing conditions can be controlled using individual vents across the 4 seed trays.
