If you're a complete noob, I'd maybe start out with a growkit or bag or whatever the fuck they're called.
But honestly, growing mushrooms is REALLY easy and you have to be almost trying to end up with mold etc. As long as you can properly sterilize shit and follow the general procedure, it's REALLY easy. You don't need a makeshift flow-hood or anything like that, but things of that nature certainly aren't useless.
It's a bit of a different story when it comes to cobweb mold on the fruiting bodies, but that can be fixed whereas mold in the mycellium fucks your entire grow over. Cobweb mold just means too much humidity... Mold in your mycellium will make your mushrooms possibly hazardous to eat. I recommend going to the shroomery and checking out their grow-teks and reading up, as they have really great info and it's where I learned how to grow.
Not sure if giving the link was ok, but also dunno if this thread will be ok so mod can edit that out if it's considered explicit lol
