On the hottest summer day or the coldest winter night, it's a constant temperature in the insulated rooms at the Dubbo mushroom farm where bunk beds of mushrooms are busily growing out for markets along the eastern seaboard.
And it's a constant effort to keep those rooms at their pre-determined heat; not only does the weather outside have an impact on the process, but the very mixture they are sitting in 'wants to get hot', according to the farm's owner David Minehan.
"We rely a lot on the electricity here; our costs have gone up and we're looking into putting solar panels in across our roof area to try and keep the power bills down."
It's one of the many pieces of information he has absorbed since he bought the mushroom farm a few years ago; it's been a big learning curve.
He wasn't even planning on growing mushrooms; he bought the then disused mushroom farm for its big family house, the acreage and proximity to Dubbo.
And then he got interested in the mushroom game and started to find out exactly what was involved in re-establishing the farm within the existing infrastructure.
"It's been an interesting journey; we were lucky that there was an experienced mushroom grower who came to work with us and we've learned a lot since that time.
"Dubbo is an ideal climate to grow mushrooms, although we do use a lot of power to keep our temperatures ideal for the crop.
"We're growing organic mushrooms here - a mixture of your classic button mushrooms and also the Swiss browns."
David says he picks mushrooms nearly every day of the year at the farm.
"We do try and avoid working over Christmas, but it really is constant here; it's always busy."
