Longer pre-wetting of straw to preserve structure during mushroom composting In my 'Pre-wet' blog, I already wrote about the importance of pre-wetting for good mushroom substrate. In this blog, I would like to discuss the structure of straw. I often hear customers say: "We are shortening the pre-wetting time because…

What is the absolute moisture content of the air? Or the enthalpy of the air? More and more growers have a handy app that reads out these values. I always ask: “What do you do with this data?” I don’t always get an answer. Because it’s not about the numbers.…

My previous blog described what the pH should do during the composting process. This blog examines the role of the raw materials, such as ammonium sulphate, gypsum and water.

Chicken manure is an important raw material in mushroom compost and for the composter as it is the biggest source of nitrogen. It is therefore vital to keep the quality as consistent and as high as possible. However, the quality of chicken manure is unimportant for the farmer, for him…

Floor humidityIf you want to maintain a natural climate in the growing room during the recovery period until about five days after ventilation you should water the floor and walls of the growing room. Do this at intervals of between one and six hours. You will notice the result as…

Does a higher filling weight give better quality?The filling weight, i.e. the number of kilos of compost per square metre, should be between 80-95 kg/m2. The general trend is the more compost, the better the mushroom quality. But is that right?Mushroom growing is all about the difference between air temperature…
