Hello All
Hot bed was rather successful, thou hard work to collect manure, four full small trailers worth. It was fresh stable horse manure, wood shavings rather than hay/straw, it was prepared Jan/Feb time, added leaves/straw/fresh pure horse manure (never again, so many flies!) in March/April. It got to a sufficient temperature (60c) for its purpose of raising seedlings.
I have now dismantled top and front, removed the material that has not decomposed, and I am now left with what is vaguely compost, do you think it is ready? It can remain in polytunnel till Jan when new hot bed is prepared.
