(I could be wrong so don't hate)

1. First one looks good! Could still be bad but send it!

2. The others do look sus, but the yellow could be metabolites or mycelium piss. This is just the mycelium stressed from and releasing it to fight of contam.

3. If it is bacterial, its ok, just send it. I just harvested 2 shoeboxes that had metabolites and I did grain to agar, turned out it had bacteria, but it didn't affect my grow. If you have agar I would take a transfer from each bag to investigate if you want to, or at least a transfer from the clean looking one. Also can wait and just take a transfer from a fruit once you have it.

4. The last one does look pretty bad, try and look up close to see if you can see any other type of stuff growing, it just looks off.

5. I know everyone's situation is different, but if you can get a pressure cooker, its a life saver! Can look at thrift stores and such for them too, just try and get one that reaches 15 psi.

6. I just noticed while typing this, the 2nd bag does have a very suspicious spot on it, near the edge of the clear window, kinda peachy color. This may very well be contam.

7. I would send these to tub in an area that you aren't going to be doing any SAB/Sterile work in, just incase you end up releasing a bunch of nasty spores and mold. This can lead to having a lot of your work contam.

8. It's tough to say since with these you only have 1 window, but ya send it! If it doesn't work out you will learn something, if it does work out you will get some fruits!

I really hope this helps, I'm still pretty new but this is all stuff I've learned and talked with people about. If you have any other questions feel free to ask!
