Nope, not outside, still snowy. But inside the greenhouse......nope, not hot there either
But I have just built a hot bed, essentially a giant heated propagator, to help germinate seeds. 20 feet of cable at 75 watts = warm, not hot, but that's OK. Gentle warmth is what seeds need. So here it is at the almost-final stage. About an inch of grit-sand has now gone on top of the cable and it's quietly warming up. In case you're wondering, there's a thick layer of coarse gravel and coarse grit underneath to ensure that the warmth doesn't simply vanish downwards.
And here's the power supply for it.
