i wrap mine in seran wrap so i its air-tight (i slowly cut out sections to let a little more GE happen the more it gets colonized), but i can still see through it :-D.

thats a good idea.
i figured bacteria and such couldnt fall upwards into it so the lid protects it even though its not air tight.

So far as I know there are two good reasons - 1) To reduce the risk of contamination, especially early on and 2) to maintain humidity levels to 95%+.

I stopped getting contamination when I stopped sealing up my tub. I tape up some of my holes, and put polyfil in the rest.

the reasoning behind making it air tight is you want low oxygen and high co2 early on in the spawn process, but as it gets more colonized (say 50-70%) I let it start having very minor gas exchange ( i cut out a square of the seran wrap and expose one hole packed tight with polyfill), then at around 100% visible colonization i cut out one more GE spot (opposite the original i cut out) to begin consolidation. i continue this and expose the tub to very minor indirect light until i see pins.... then i cut off all seran wrap and remove about 1/2 of the polyfill from all the holes and turn a fan on in the room
..... just like to mention im no pro, this is just what i know to do right now, im still actively learning though.

its old news you absolutely do not need or want a air tight tub during colonization, a tight polly stuff and kept out of the light is all you need.

You dont have to read it. Just dont cover your Tub with a trashbag.

the trash bag method is old, when people thought light would cause pinning before full colinisation.
Now that we know that doesnt happen untill full colinisation, yoiu dont have to do this. Infact i highly recomend exposing substrate to light from day 1.
During colinisation you only want gas exchange. as mycelium digests food it produces co2, if it gets too high growth will stall. you want to to escape, but you dont want FAE which would cause evaporation of moisture from your substrate (which is a pinning trigger)
In my mini double tub grows all i would do is dump the substrate into the tub, put the lid on and tape up with holes with micropore tape and let it colinise. Once colinised the hoels would have the tape removed for fruiting.
My last year of growing my substrates would be exposed to light from day 1 (inoculation)

^ Ya I tape all my holes with Micropore tape then just put the lid on to allow GE, Onced colonized, let consolidate for a week (If u want) then remove the Tape and replace with lose poly.

I think Brownian motion would let bacteria in, but pasteurized substrates aren't as susceptible to contamination as sterilized subs.
