Can Monotubs & Grain Spawn Survive 16 hours Below Freezing?
    #27690115 - 03/10/22 07:05 PM (2 years, 10 months ago)

Ok, so I've searched the forum, and have found a range of answers, so just trying to gauge if I've ruined my monotubs and grain spawn bags.

Accidentally had heaters off in monotub & grain rooms for ~16 hours. Before heaters went off, rooms were ~72F. Accidentally turned off heaters for ~16 hours. Rooms then ranged from 20F-37F.

Monotubs and G2G grain spawn bags were started on same day heaters shut off, but I also have two monotubs that are ready to switch to fruiting.

As soon as I realized heaters were off, I turned heat back on and got temps back to normal over the course of two-three hours.

Did I just ruin my new grain spawn bags and monotubs or is it possible for them to survive/thrive since it was only for 16 hours?

I realize it's likely a wait and see scenario, but if chances of survival are slim, then I'll know to replenish my supplies/materials sooner.

Thank you for any insight!

The substrate wasn't frozen. And there was condensation on the inside of the tub lids, but it wasn't frosty or frozen. The room was definitely cold though.

The grain bags did have some moisture in them and since I did the G2G yesterday, I just went ahead and mixed the bags to redistribute the moisture (I know you're only supposed to shake once, but I figured since I just did them yesterday maybe I could get away with it ... .)

Since this most likely is a wait and see I’m going to bet it’s fine. Myc creates its own warmth and it takes a long time for something that big to freeze all the way so I’m guessing it got really cold, but not cold enough to do enough damage to kill the grow

:shrug:

Hope it works out for you brother!

I just recall reading that a few different places, but can't remember specifically where.

I'll take the optimism. And I guess I'll know within a couple of weeks what lies ahead. Fingers crossed.

A delayed update in case anyone else needs the info. I lost 13 out of 16 grain spawn bags, with most of them getting wet rot and four getting trich. As for my monotubs, I lost six out of 16 to trich (I'm assuming related to other issues and not temp drop), but the other 10 survived so all wasn't lost.
