Direct sunlight effect

Hello people, this is my first grow ever.
I am colonizing six bags of pasteurized straw with pink oyster. I have them close to a window that remains half-closed during the day to give them indirect sunlight.
Yesterday someone opened the window and they got about a couple of hours of direct sunlight before I noticed and closed it. I've read around here than more than 10 minutes is not recommended, but I'm wondering what the effects are going to be on these bags. Will they die out?
So far, the ones on the back side, those that received less light, have just started pinning (after 11 days), but I'm not sure about the ones that got fully bathed in sun (and haven't started yet).
I guess I'll know in a few days, but I would expect tropical mushrooms to have some endurance for it. I've found photos in this forum of blocks fruiting outdoors in direct sunlight.
Here are what seem my first pins (just made the holes bigger and moved the bags into a fruiting Martha):

I think you'll be fine. I've colonized and fruited pinks next to a window and have observed no ill effects. I think the idea of light being detrimental during colonization is old info. RR has repeatedly said this.
On a side note, it's hard to tell, but your straw looks a little bit on the wet side.

Peace and long life.

Thank you, now all the bags have started pinning (in just a few hours).
Maybe the direct sun wasn't that bad after all.
I'm not sure about the humidity inside the bags. They've got holes in the bottom and drained well after pasteurization.
Since I have them in a humidified Martha, should I stip the bags from the substrate now? Pink oyster mycellium doesn't seem very storng and I don't know if it would keep the substrate together.
For now I've just cut large holes around the pins.

Leave them in the bags. They will dry out too much otherwise. I don't think direct sunlight is that bad for the mycelium, but the temp inside the bag may get too hot in the direct sun. Think of it like a kid in a locked car, in the summer with the windows up. Pink oyster mycelium is pretty strong. Perhaps your bags aren't fully colonized. They can do ok with humidity of 65% but need LOTS of FAE. They will do best at around 85 degrees. Mist them gently at least twice a day or more. They grow super fast. They are a bit tough, and the stems are nearly inedible. Good flavor though for in my opinion. And beautiful.

Congratulations! It looks like you took the bag off? Hmmm....

Just out of curiousity where is your martha located?
Fruiting a lot of oysters in a room can cause spore lung if you aren't careful.

The Martha is in the study room. I haven't thought about spores, and now I'm a bit worried about contaminating half the house. Even if it's just the Martha, how to clean it properly for future growths? I plan to cultivate other species.
The other problem I have is I don't know when is the right time to pick them, and they're growing fast

Not to freak you out, but as far as spore lung, here's a good study. Most of the participants were only exposed for a few months before developing symptoms. http://occmed.oxfordjournals.org/content/48/7/465.full.pdf
To clean your Martha, just wipe it down with a bleach water solution. As far as harvesting, pick your oysters right as the edges of the caps start to curl upwards. The earlier you pick mushrooms, the longer they'll typically keep. With pinks, you'll only get a 5-7 days at most before they start to look really shitty.

bleach is not a cleaner its a sanitizer. Trying to sanitize a dirty surface is a waste of time, it must be clean of all dirt, grime, spores and growth before sanitizing. To properly clean your grow room use some warm soapy water on a small cloth rag then rinse well with a hose. If you really want you can use a sanitizer but your fuiting chamber is not a sterile environment so its not really needed, and inhaling chlorine fumes is not good for your lungs in excess.
With your spore issue, install an exhaust fan that blows air out a window/vent. You want a slight negative pressure on the chamber to exhaust all the spores and none into the room. Use a simple fan that can be cleaned easily and is readily accessible as your exhaust fan will get covered in spores quickly much like a ceiling fan with dust.

This ^
The spores can be cleaned with soap and water, followed by bleach to disinfect everything. It's the airborne ones that are dangerous and hard to clean. Air filters and an exhaust fan help, same with picking before the caps curl up.
Not trying to scare you, I only wanted to make sure you knew about oysters and the allergy type symptoms they can cause if you dont filter the air so you can adapt around the danger and continue growing.

Seems that I'll have shrooms - while they look a bit too small:

Yup. Should've left the bags on.
