Our chilli pepper seeds have germinated much sooner than usual thanks to a windowsill propagator heat mat. We mentioned in a recent post we were using one in a trial and would blog about it if we liked it.
In just 8 days the first seedlings appeared with more popping up over the following days. As expected, a couple of seeds haven’t germinated but we have more than enough seedlings due to sowing more than we need.
The windowsill heat mat we are using looks like this:
It’s simple to use, just plug it in and place on the windowsill of your choice. We covered our seed trays with clear lids to help with humidity and kept the heat mat on for most of the day, switching off at night (purely for our own peace of mind!) allowing a radiator to provide a source of heat. The heat mat fits a standard size windowsill without hanging over the edge and can take up to two full sized trays, much more if the trays are smaller. It heats up quickly and doesn’t get too hot to the touch.
If you’re interested in getting this particular heat mat you’ll find it here. Priced at £16.49 with free UK delivery it’s a cheaper alternative to most heated propagators but still an expense. If this doesn’t suit your budget it’s still possible to germinate some seed by using a radiator or warm airing cupboard. Once germinated, seedlings can grow at lower temperatures in a bright room. It will take longer but you should see some decent results.
If you do decide to get one please do let us know how you’re getting on.
