To make a hotbed, stack your manure high. Tall and skinny is preferable to wide and shallow, which loses heat quicker. The ideal hotbed would be around 1.8m (6ft) square, with a height of around 60-90cm (2-3ft), though you could go a little smaller, or eke out your manure with equal parts collected leaves.
How long does a hot bed stay hot?

How do you heat a Polytunnel without electricity?
Lighting candles inside the polytunnel can help to raise the temperature. A very effective way to grab some free heat is to position some large rocks around the inside edge of the tunnel; the rocks will absorb the precious Winter sunlight and retain the heat, helping to raise the temperature on cold days.
How do I keep my raised bed warm in winter?
Raised beds will warm up more quickly thanks to the free-draining conditions within them, so if you have raised beds, start your first sowings here. Any soil can be warmed up by covering it over with black plastic, row covers or garden fleece.

What is a hotbed gardening?
What is a hot bed? A hot bed provides bottom heat, using manure rather than electricity as the heat source, thus speeding up plant growth of seedlings and tender plants. The heat source: Fresh strawy manure – in a layer 60-90cm deep (after treading). As the manure breaks down, it generates heat.
How often should I water my garden in 100 degree heat?
two to three times per week

However the construction for an outdoor bed is a little different, and if that’s what you’re looking for, you probably need the book. A hotbed uses the heat from decomposing organic matter to raise the temperature of soil in an enclosed space, in order to extend the growing season.
What kind of soil do you use for a hotbed?
A planting medium of topsoil and composted manure tops off the hotbed. Soil has been backfilled around the sides of the hotbed to provide additional insulation. With the posts in place and the frame constructed, I used soil I had dug out of the hole to backfill around the outside of the frame.
