Help, oyster mushroom pinning and temperature control

Help, new to mushroom growing and i really want to do it as a business since there are barely any gourmet mushrooms growers here in Argentina, i have questions about inducing pinning and temperature. In my Martha TEK my mushrooms pinned and grew fruit but it took way longer than they were supposed to, some almost a month and with horrible yield 20% BE(first flush so far). First two weeks i had them at room temperature but since that didn't work i eventually moved to a room with AC and set it at 20C, after 2 long weeks my p.Ostreatus pinned, but i still had bags of p.Pulmonarius which i think likes warmer weather so i set the AC to 24C and they pinned the next day, not sure if it was the temp or just a coincidence. How long should they normally take? Is it the norm to grow warm weather species in summer and vice versa or should I have an AC in the growroom? I have watched a LOT of videos about mushroom growing in youtube but I haven't seen a lot of people talking about how they cool/heat their grow rooms, idk maybe i missed something. Correct me if i'm wrong but the colonisation room should be 5-10C hotter than the growroom to induce pinning right?. Is this temperature different achieved by heating or cooling one or the other, or does the fact that the colonisation room is ventilated less and at the same time the bags produce heat enough for this temp difference? Does the ventilation,humidity and evaporation in the growroom also help cool it a bit? My bags are poplar sawdust and 65% water,i am now colonising some with wheat bran and better sterilization because my first attempts got contaminated and only the sawdust bags previously mentioned survived. I'm sorry asking for so many questions(and i still have many more) but it's frustrating because i have read books and forums, joined about two dozen facebook groups and watched just about all the videos on the main mushroom cultivation channels on youtube, i have made my own spawn from the original and have had success with agar(cloning,spores,strain isolation?) and are currently making LC but can't seem to trigger pinning fast and get decent yields. I am currently building a nice big fruiting room and would like to get good results and turn this into into a business because i would love to live of growing mushrooms commercially.

Welcome to the Mushroom club. I will attempt to answer some of your questions the best I can.
As you have discovered by your questions there is a lot more too it than just setting things up correct and Mushrooms everywhere for doing this for a business. And so think of it this way: Right now you are getting some experience under your belt learning and testing and trying and failing. But you only really fail if you don't get back up. Translated, you can read and watch and study all you want but just like in school it only prepares you to start living/working it doesn't complete your ability until you get the experience under your belt of doing, which is what you are doing now. I say this to encourage you to keep going forward and not get frustrated nor give up in case you try and bite off too much at once too quick.
Generally Oysters have a 2 week cycle per growth stage. Which is a rough time frame. They can grow at 10 days or longer. 2 weeks though is a good gauge on how well you are doing with your grow area setup. Per stage meaning 2 week colonization of spawn, 2 weeks colonization of substrate, 2 weeks to fruit.
Colonization optimally should be roughly mid 70F so a good temp is 75F ( sorry I'll let you do the conversion to C) for a faster colonization time. Too hot and you can overheat it.
Whether to grow warm weather species in the summer and vise versa for cold is entirely up to you and your grow situation on what works best.
How everyone heats/cools their grow areas varies. Some people use earth tubes for example. Some use window ACs and space heaters. Some don't use anything and just grow outside. But if you have a specific question about a specific setup someone here should be able to point you in the better direction.
The temperature difference between colonization room and fruiting room is achieved by how you want to design it really. Where everything is setup etc..
I hope some of this helps. I know some are general answers ....
-------------------- Plan to win or you are planning for failure. Don't let anyone tell you you can't do it. Just figure out the solution. Even if that means banging your head on a wall until the solution oozes out of you.

Thank you for the info and encouraging words, i will keep at it, i kinda knew this information but atleast know i'm sure i'm doing something right eventually i will post a design of a growhouse to see what people think before i build it because it's not a small space and won't be cheap. I do wonder if growing the same species all year round and cooling and heating respectively would be economically viable. Here in Argentina Mendoza it gets pretty hot in the summer but in winter it very rarely snows, at most a few mornings a year.

You would have to crunch the numbers for your area to find out. I don't know Argentina. I know it can be economically viable in the USA.. but that won't help you there since our economies are different. There are mushroom farmers all over the world making it work some how with or without electricity though... Some people use the earth's natural heating and cooling for growing. One person I know of installed earth tubes to heat and cool their fruiting chamber and his heating and cooling temperature situation is similar sounding to yours.. RR had installed his entire fruiting chamber in the ground to use the earth's temperature. So there are ways.
