A lot of farms are afraid that water directly on mushrooms will damage the quality but I disagree with that. Of course it depends on the amounts of water you use and the moment of watering, those details are very important but if managed well the water on the mushrooms will give them a smooth cap and some extra weight. What we need to keep in mind is that the moment of watering is very important. Wait for watering on the 1st flush until you see compost activity. If there is no rise in compost temperature wait with water until there is. Normally you see the activity starting on the first picking day when you pick about 0.5 to 1 kg/m2. I always like to water on that first picking day, where the compost just starts to get activity, and let the mushrooms dry naturally, with no force of the fan but with fresh air. What happens is that when you run higher fan speeds after the watering, the fresh air damper will close. You can put a drying program where you lower the CO2 a bit but still the higher fan speed will not increase the amount of fresh air that is needed to dry the mushrooms.

Instead dry the mushrooms naturally and without too much help from the fan speed. Speeding up the fan a lot is not sufficient and is actually working the other way around. When the room is watered the RH is high so the climate system will automatically start drying the room. Leave the fan speed the same so some extra fresh air will come in to do the drying process. Make sure to remove all the access water from the floor directly after watering, if not the process will dry the floor first and the mushrooms will stay wet longer. Make sure you watch your outside conditions to guide this process, with very high humilities you have to use a drying program or consider not too water.


 

 

On July 3, Brazil mushrooms farmed in mushroom base of Nanyou Village, Malipo County, Yunnan Province of China are evolving into the maturation, growers are busy with mushroom picking, sorting, drying and marketing.

“Brazil mushroom farming is short in cultivation period, from the formal cultivation to marketing, Brazil mushrooms only take 60 days or so. Now, it is the GOLDEN picking season of Brazil mushroom, in each shed, daily picking volume could reach 1500 kg or so, for growers like us, daily net incomes could come to over 10,000 CNY,” introduces one of local mushroom growers passionately, going on that by 2020, 10-12 flushes of Brazil mushroom are expected to be realized and cultivated, the anticipated gross output attains at least 312 tons while the projected annual output value hits 2.8 million CNY in Nanyou Village.
