Cubensis growth in colder temperatures, some general questions

Gday everyone, just a few things I was wandering about cubensis in a colder climate (54f - 72f).
Q1. Colder colonising of Rye spawn/brf cakes will help keep contams from growing, but also take much longer to finish so bigger window for it to get contaminated?
Q2. Cold grown fruits will be 'meatyer' and weigh more(more yeild per flush)?
Q3. I'm using a simple mason jar 1 quart, with single 1/4 inch hole in the middle and 90mm easy felt disc on top and secured by the lid screw. I inoculated some grain 10 days ago (non-rhizmorphic growth) with agar transfer. There growing with no signs of contams but is there much risk of jars drying out and stalling or get contamed if the jars take upto 3 months to fully colonise?
Any knowledge is much appreciated

1. The temps you're referencing won't cause any real delay. It's high-temp swings you want to worry about. My temps get as low as 38 (you read that right) but average 50 every day when I get up and I still have very acceptable colonization times. Definitely helps with keeping contamination down/at bay.
2.Generally speaking, yes.
3. If your jars take 3 months to colonize, you have other issues. You shouldn't be having any issues with that setup. I use larger holes with poly (among other things) that allows a whole lot more exchange than your filter disks, and the only drying out I've ever had happen was with 3/4 full qt jars of wbs or wbr that I prepped a little dry to begin with (and they still colonized). Never once had a brf cake dry out in any way in a jar.
No worries, bud.

You don’t notice a big difference in grain spawn colonization time that low??
I run my room pretty cold 52-72 usually and once I get to bulk everything seems about the same but for some reason my quarts of wbs just drag under like 60ish.
I was recently out of town for five days and left the heater off so it was prob 40-55 the whole time. My shoeboxes were fine, some golden teachers grew with the most solid stems I’ve seen yet.
But I had dropped agar into quarts a few days before I left and they were doing great. I was pretty excited to see how far along they got while I was gone but they had barely noticeable growth, and the myc looked different. Once I turned the heat back on the jars went right back to normal.
This was only jars of a Mazatapec clone, and the first time it’s been cold for so long so it could just be the culture I’m running.

Amazingly, no I don't. Granted, I could be seeing faster colnization times, but mine strike a consensus-backed average. Spores2agar/clones show growth in a couple days and are ready to transfer in like 5-6 days, generally. Brf 1/2 pints are finished in less than 2 weeks, my qt wbr and wbs jars take 3 weeks to a month at the most (my wbr jars are super-fast at times, but my wbs jars lag a bit). Nothing extrordinary in either regard, but certainly not bad (especially since all my work since I've started cultivating again has been developing a stock from hodgepodge ms, up until very recently). My time tables have been comparable to those I've experienced growing in much more typical temps in years past. Also, my lows don't last very long- maybe on the coldest nights we're talking 38-40 for four hours or so before I jump out of bed and blaze a fire (which raises temps by 10-15 degrees very quickly). I have had mmaybe five or six days where I had trouble getting the house over 60 out of the last two weeks, and lots of time around 60-65. I'm also growing bulletproof varieties like B+. PFCL, GT, etc... Not terribly demanding. I have to break out my old grow tent to start growing pans next month, which is going to be a pain in the ass since I'm wiring/re-woring the house... Back on topic though, I am amazed how little temps have affected growth. The only problem I've had with temps is relative to RH. Huge temp swings, a wood stove, and an unfinished environment really complicates matters. If I wasn't as attentive to every other need my mushrooms express, and didn't have things dialed in, I wouldn't be sitting as pretty. While my experience may not be standard, it serves to illustrate how resilient cubensis can be, and how forgiving they can be in response to temperature swings. My contam rate is ridiculously low, I might add. I firmly believe the low temps have played a role in my success. It's something I want to continue to expereiment with. Oh and also- yes... it does change the appearance of my growth on agar sometimes if it really drops/swings. There is of course banding...

Wow this has inspired me to run a test. I have some clones going on agar that I plan to put in lc after a couple more transfers. After the lc gets done I'll make a bunch of grain jars and have some of them inside my grow room (75ish) and some outside my grow room (60ish, maybe less) I'll record the progress and compair. Sounds legit right being the clone lc should all grow relatively the same speed?

Look forward to seeing the results. Sounds like a good way to proceed. I figure that for the density of my fruits and low tamtam rate, I'm happy with whatever I'm sacrificing in turnaround time. I'm just now rounding the standardization corner with my agar work as well- getting back in the swing of things- and will be able to have some fun experimenting now that I'll have more controlls in place. I get to do outdoor grows in AK temps this year as well and am excited to see how my kiddie pools fare in our "summer" conditions. Cold weather, schmold weather.

Awesome, thanks for the feed back guys(I do read everything) lots of juicy knowledge. Seems like cold could be better unless your in a hurry

That’s pretty cool man. The cold absolutely shuts down contamination. When I left I had a few clone tissue plates that were so bacterial it was literally running in a stream and pooling at the edge of the dish. After the few days with no heater I got back and all the bacteria had dried up and mycelium had grown over everything.
Do you get hollow stems still? The couple gt that popped up while I was gone were extra thick and completely solid from the sub to almost half way up the stem. Usually my gt are super hollow. I kept my room a little colder after reading some threads about it but I guess the couple extra degrees really makes a difference.

That's awesome, cool story of mycelium winning the battle ha.
My stems are always just slightly hollow I'd say there pretty thick inside though I'm not the best at seeing it cause I've never had warm grown fruits ha
