Hotbed are grand, but the article is a bit scimpy on important details
You will need a layer of something over the raw manure to make sure it doesn't scold/burn/kill your seedlings. Its not just the heat that will kill, but the raw piss. You will have difficulty putting seedlings in raw manure.

You will still need to think about thermal management.
The victorians used to have hotbed out the front of green houses. They were made of brick, angled at about 120 degrees. They had a bed for the manure, that ran around the outside and took up ~50% of the space, and a bed inside that was just soil. This allowed them to change the manure to keep the temperature even.
- Liquix 4y ago... add a 15cm (6in) layer of potting mix into the cold frame to begin warming up – you will be sowing or planting into this, not the manure. Is another layer between the soil and manure required?
- KaiserPro 4y agodepends on the plant. If its something that sends down long roots, you will need a barrier. For something like beans, you would traditionally dig a deep trench (as in 4foot) and put a layer of manure, with news paper on top, by the time the roots got that far it would be rotten enough. It might be better to use coffee grounds or fine wood chippings, as they are equally as warm but less toxic in the raw state.
