Getting a heated propagator for the greenhouse

It’s been a week since we sowed our first seeds in the greenhouse that our good friend Richard is kindly lending us.

It might be early days but so far there are no signs of life. We had a basic thermometer in the greenhouse and, even though the greenhouse has a tube  heater, we were worried that the temperature was dropping in the evenings and at night below what we needed to germinate our seeds.

On average, plants need a temperature of around 15-20 degrees centigrade to germinate, although some plants may have particular temperature requirements outside this range.

Andrew decided that we needed to raise the temperature under the seeds, so we went in search of a basic propagator. We didn’t want to spend too much money so went to a DIY store rather than a garden centre where we have found prices tend to be higher.

We ended up in Homebase where we found a Stewart essentials propagator. It doesn’t have a thermostat, but the instructions say that it should achieve a temperature of between 10-15 degrees centigrade above the ambient temperature.

We have set up a max/min thermometer with a probe in the propagator to see what temperatures we achieve. We’ll let you know how we get on.

In this video, we set up the propagator and sow some more seeds – including the pot black and rose bianca aubergines that Sandra won from Mr Fothergills.

We had a lot of fun making this video. Be sure to check out the out-takes at the end of the Video!
