Need to slow my jars down on purpose
    #27998391 - 10/14/22 10:05 AM (2 years, 3 months ago)

First time grower here.  I’m staring down the barrel of a good/bad situation with the KSSS, JMF and JF jars I’m working with and need some advice.

My first go at half pint cake colonization (whatever substrate mix comes in the Midwest Grow Kits Mega setup) has 2 of 3 strains (KSSS and JMF) doing extremely well. 

Too well. 

Why, you ask?  Because I’m way ahead of schedule for what my noob mind anticipated as far as colonization time.  I have a trip out of state at the end of next week that will keep me out of town for yet another week. 

The fastest growing jars are probably right at 80% and gaining approximately 3.5mm-4.0mm of mycelium per day.  Incubation temps are presently hovering between 75-78F.  At this rate, based on an eyeball estimate, odds are good they’re going to be ready for birthing right as I’m leaving for a week or just after I depart.

Is it a good idea to drop my temps into the lower 70’s, or even cooler, to slow things down and buy a few extra days so I can get home and birth them at the ideal time?  Will this cause unforeseen issues?  Thanks for any advice you can give.

In my opinion they’ll be fine if you leave them as is.  Cakes enjoy a week of consolidation after they’re 100%. Basically ensuring all of the substrate in the middle of the jar that you can’t see is colonized.

How are you heating your jars?  70F, as far as I’ve seen, is just fine.  Higher temps can cause more bacterial colonization. Unless you’re in Alaska where the temp is -10F you could probably ditch any extra heat source you’re adding.  A good general rule is if you’re comfortable your myc/shrooms are comfortable, temperature wise.

:whathesaid:

the worst thing that could happen is you come home to some fruits in the jar

If you're past the initial week after full colonisation, just stick em in your fridge before you leave and they'll be good to go when you get back.

Many thanks for the replies, guys.  This is exactly the kind of info I needed, and I need all the help I can get.

I’m controlling temps with a graphite heat mat, separated from the tub body with an unfolded towel.

Ok, good to note about probably not needing added heat.  I keep the house at 68 in the winter.  Thermostat is downstairs, so the upstairs is likely slightly warmer.

Total aside: regardless of the position within the tub, my JF cakes are significantly behind the other 2 strains as far as colonization.  My best one is MAYBE at 30%.  Is this a normal thing for JF or likely just an aberration with the genetics I happened to get in my syringe sample? 

I did notice that the cakes towards to front of the tub, where a little bit of light sneaks under the closet door, are all notably ahead of the jars towards the back of the tub, regardless of strain.  Don’t know if that’s pure coincidence, or if there’s something to a little bit of light exposure helping things along.

68 is fine

I figure this is a good time to show a pic for reference as to why I asked this question: my fastest and slowest colonizing jars as of today, side by side.

The JMF jar on the left is definitely over 90% with the mycelium about to overtake the last of the substrate, while the JF jar to the right is maybe 30% if counting all inoculation points on all sides.  All jars were inoculated on the same day/same time using the oven technique.

Remove the foil, could be stifling GE. Fully colonized jars should be fine to sit for another week before spawning. It's usually good practice to do so anyway to allow for consolidation

So anyway, uh...

always leave your jars vertical and agitate them as little as possible. the verm layer only works if it remains undisturbed

Gonna leave everything as is now since the jars are already inverted and ever so slightly cracked for FAE.  The advanced one I posted the pic of above is over 95% and the bottom is almost totally colonized with no signs of contamination. Fingers crossed that birthing will be good to go when I get back a week from Sunday.

So, I think I’m getting another lesson here, this time on rhizomorphic vs. tomentose growth.  The jar on the right (different than the one in the previous post) was slooooow to take and I honestly thought it was a dead jar with some mold growing until reading up on here and on Reddit shroom cultivation threads.  It was inoculated the same time as the jar on the left but just now becoming a noteworthy growth.

Correct me if I’m wrong, but that right jar is perfectly healthy and just a different type of growth, correct?
