be careful when using compost or manure as a heat source in a cold frame. If not managed properly and too much ammonia is released, you can harm your plants. I lost all my tomatoes one spring due to ammonia toxicity from using manure as a heat source- it was too 'hot'.


I'd also consider the current recommends to not use fresh manure closer than 90 days to harvest if the edible portion of the crop doesn't touch the soil, or 120 days if it does. This would work out all right for some crops but not others, I think.
