Like most NWBs I’m battling the mean green. My tubs get fully colonized with beautiful white and then the green shows up usually with the first pins…one time on the cut bases of my first harvest. My question is, what is the likely culprit with this timing? I have monitored humidity and keep it around 85% with temps between 75-82. I have a grow chamber, but it shows up both inside and outside. (Both of the tubs in the photos were lost to green mold after these photos)

It's probably your spawn. Got any pics of your jars or bags?

Could be, I’ve been working on some issues there…too much moisture, not enough and have had a low success rate (they have been fermenting) But I’ve built a flow hood, use only new needles and skipped the break and shake on the last ones and they look the best so far.

Your spawn is definitely the problem.

If you are using the ub tek I'm guessing you aren't cleaning cultures on agar yet either. (sorry if I'm assuming incorrectly). If you are doing spore to grain, that's where you can stop your search for where it went wrong. They have a ton of moisture, which is a sign of contamination.

I’ve had the same luck with both liquid culture and spore syringes from 2 vendors (ITW & MWG) I use .5cc and have switched to a hole puncher to increase ventilation. (I REALLY appreciate the help all)

how did you build this? unless you got some insane deals on the components, anything that didn’t cost you at least $400 is probably not a legit hood & is only going to keep causing you failures.
sounds like you’re willing to learn & jump right into things, i highly recommend you look into using agar & working from spore prints. you’re gonna see 1000x better results from that than you will with what you’re currently doing & it will honestly save you time to start sooner rather than later

This is my first grow (I went with the bag method), and I have some contamination concerns. I was hoping someone here might be able to tell me what is going on/what to do. The cake has produced fruit, but, a few nights ago, I accidentally left my heating pad on at way too high of a temperature and "cooked" the bottom part of the substrate in the bag for about a day. I noticed this error and readjusted the temperature. Now, the rest of the bag's mycelium appeared, and still appears, to be fine, but the bottom became discolored; and, a couple days later, these pink streaks appeared. I was unable to find an example of this online anywhere that matched what I was experiencing (maybe fusarium?). What exactly is this contamination? What should I do in this circumstance? If I need to toss the cake, is it ok for me to harvest the fruit that has already grown? Also, if I need to toss the cake, should I bury it, or should I just get rid of it altogether?

I figured. Could you elaborate a little bit? If the fruit looks fine, should I harvest them? And should I bury the cake, or just pitch it straight into the trash?

if the fruits look ok & you should be safe to harvest them, but yeah the tub is fucked. any time you see contam like that, it’s pretty much game over. don’t know exactly what it is but i know it means your sub is dying quick

Ok. Thank you for your input. Do you think that I should bury the substrate? Or do you think that that is even worth the trouble in this instance?

idk, i’ve never really buried any subs. if you’re ok with digging a hole for potentially no reason i don’t see what you have to lose by burying it

I'd say it's worth a trip out back to bury them. Pretty good chance you'll notice some shrooms popping up in the future, especially if it's already producing.
