How mushrooms grow and the yields are determined at filling. Assessing the compost and casing soil determines the final quality of the mushrooms. After this assessment, the settings are made on the filling machine. Any mistakes made at filling, will haunt you for the rest of the cropping cycle. On…

Dry bubble disease may cause a lot of problems because the spores spread quickly. It’s essential to identify and remove the first affected mushrooms to prevent an outbreak of the disease throughout your entire nursery. So how do you remove the first infected mushrooms?Dry bubble disease is spread by spores.…

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…

Why is casing soil used? There are two main reasons: 1. the Pseudomonas putida bacterium; 2. to regulate evaporation. Mushrooms will not grow without evaporation. The casing soil structure, through the depth of casing and on the surface, is the factor that determines how much water can absorbed and released.…

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.…

Climate in the growing roomAll growers recognise the importance of climate in the growing room. How the climate feels when you enter the growing room is a good indicator. Sometimes what your instinct says goes against what the data from the climate control computer suggests. Experience can help you finetune…
