Airflow per meter cube for oyster

Hello everyone
I am new to this forum although, I have been reading post since a few month now. I am currently growing oyster mushroom in my apartment and building basement. I am thinking of buying a shipping container to start a small grow room. I have been talking to some professional grower who all told me the volume of airflow per cubic meter is very important for the fruiting stage if you want to maximize the yield and their speed of growth. I tried to look in previous post but could not find this number, I read some research paper but it was not for the oyster and I was quite lost with all the mathematic equations... I was wondering if any one had this info or something close to it? Thanks a lot for the help Cheers
Ps: be kind if I make mistakes, english is not my first language.

5-10 air changes of your grow room volume per hour.
Example,
For 100m^3 , a fan of 500-1000 m^3/hr constantly,
or 100m^3 per minute for 1 minute every 5 or 10 minutes

Ok thanks a lot for your answer. Is this concerning only oyster mushroom? But considering that I am looking into a martime conteiner of 40", which is 68m3, I would need at least 340m3 per hour of changing air! Woaw I didnot think it would need such an important airflow channel. Also I got an other thought, since I would be in a metropolitean area (near Paris), pollution level have been quite hight in the past few month, would that affect this data, since the quality of air won't be that great?
And by curiosity, where did you get this information? Do you have any reading to recommand on this subject or video? I am trying to get all the knowledge that I can. Anyway thanks for the info.

AMYCEL 3015 Pleurotus ostreatus {Picture of Mushroom} Marketing Characteristics: Amycel3015 Pleurotus ostreatus produces a whitish gray to blue gray fruiting body. Depending on which growing practice is used, it will form large mushroom clusters or smaller, single mushrooms. This strain is a cap tongue shaped, maturing to a shell shaped form 5-15 cm (2-6 in) in diameter, with even or wavy margins, and an off-centered stipe Note: The following are recommendations for growing Amycel's 3015, Pleurotus ostreatw Due to the many variables involved in growing mushrooms, Amycel makes no guarantees regarding these recommendations. General Characteristics Amycel's 3015 is a fast growing, self fruiting and high yielding, Pleurotus ostreatus that adapts readily to many different types of growing conditions and substrates. Though in nature wild strains are numerous in the fall and early winter. Amycel' s 3015 under controlled environments, is a year round crop. Substrate and Pasteurization Substrate: This strain accepts a broad range of substrates. Typical materials can be chopped or whole wheat straw, hardwood sawdust, cottonseed hulls, sugar cane bagasse, paper mill sludge, and other agricultural waste by products. After pasteurization, limestone or calcium carbonate should be added to achieve a pH 6.8 and 7.2. Depending on the material used, nitrogen content of the substrate after pasteurization should be between 0.6% and 1.3%, with moisture between 70% and 80%. Pasteurization: Typically pasteurization is done either by injection of live steam for a minimum of2 hours at 70° - 75° C (160°F - 170°F) or by submerging the substrate in a hot water bath for 1 hour 70° - 80° C (160°F - 170°F). Spawning Spawning should take place after the substrate has cooled to between 25°C and 30°C (75°F85° F), with rates between 2% and 4% of the wet weight of the substrate. Those new Amycel's 3015 are encouraged to use the higher rates until becoming more experienced with the strain. Temperature: 25°C and 30°C (75°F-80°F) not to exceed 33°C (92°F). Spawn runs normall) takes between 7 to 14 days. Thermal death occurs above lO4°F/48 hrs Relative Humidity: 90-100% Carbon Dioxide: 15,000 and 20,000 ppm or 15% to 20% by volume. Flushing: Amycel's 3015 will fruit at a very wide range of temperatures, lOoe to 28°C (50°F - 80°F) with the optimum range between 13°C and 16°C (55°F - 60°F). Humidity: 95% to 100% during for formation of the primordia. Carbon Dioxide: 600 PPM - ventilate to a minimum of 4 rresh air exchanges each hour. Light Requirements: 2,000 lux/hr - 12 hr/day .. Watering: Mist 1 - 2 times/day 2 Cropping: Crop while the leading edge of the cap flat. Overly mature product is characterized by an upward curling of the outer margin of the cap. Humidity: 85% to 92%. Carbon Dioxide: Below 600 ppm - ventilate with a minimum 4-6 fresh air exchanges eac hour. Watering: Mist regularly to prevent cap splitting and to keep resting pinheads viable. Light: 2,000 lux/hr for 12 hr/day .. Flush Intervals: Approximately every 10 days. NOTE: Workers are encouraged to wear masks whenever working around spore producing mushrooms. Spores may cause allergic reactions in some workers. ---------------

There's a Amycel in France.. Great commercial spawn at a good price..

Sorry to hijack the thread but my mini greenhouse is 159cm x 120cm x 49cm which this page works out to be 0.93492 m3
My fan apparently does 198 m3/hour - how often would i need to run mine? i have it on contantly at the moment but im currently waiting for my first flush so i dont know how well its doing.
