Hot, Hot, Hot?

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.

You had me wondering there. It's one way of getting some seeds started - maybe the only way at the moment.

I think everything is going to be late this year!

I'm well impressed Woody...especially given that I've only just got round to washing out last year's pots and haven't actually planted any seeds yet - I've got me spuds chittin' though if that counts?!

That definitely counts, especially as I haven't started that yet!
