Does early pinning mean time to fruit?
    #18842733 - 09/14/13 10:35 PM (10 years, 4 months ago)

I'm a first time grower and I got 8 BRF jars in an incubator and one has started to pin a little but the jar isn't fully colonized with mycelium yet, think I should move it to a FC?

Wait until it is fully colonized.  Then wait a few more days for consolidation.

Early pinning before full colonization could possibly mean contamination.

it could also mean u have let light get to the jars. if there is any light (even a couple hours of dim indirect light) it will trigger them to start pinning.

do u see any off colors in ur jars? green, black or any other "not white/fluffy stuff? or any slime? if not then they are most likely not contaminated.

if not just weight till full colonization to fruit. dont want any not colonized substright to be open to attack by other organisms.

Not necessarily, you actually want A 12/12 lighting schedule throughout the whole process (indirect light during colonization and direct during fruiting). It helps develop a circadian rhythm.

I have to disagree with this statement. Light is not a major pinning trigger IMO, I am sure there are very experienced growers who are going to argue the point. Pinning is triggered by evaporation of moisture from the sub. So if your jars are fruiting in-vitro it tends to lean to the contamination scale.

  When there are other biological fighting for the same food source the myc can start to try and reproduce. Nature's fight or flight.

Early pinning in a brf jar is usually a sign of a contam or substrate that is packed too tightly. In other words the myc thinks it has colonized everything it can and it pins

I bet you used the tall skinny jars didn't you op?

Nonsense.  Don't spread disinformation as fact around here.  Mycelium should be exposed to ambient room light from day of inoculation as has been known for many years.  Light is not a pinning trigger until after full colonization and an increase in air is given, and even then it's a secondary pinning trigger.

Thanks RR for clearing up the confusion on this, there was a lot of confusion on some of message boards about this and I wasn't sure.

As this is my first grow so I didn't except much from the first round of cakes but most of the jars are nearly full colonization and look very healthy. I think the trigger may have been a drop in temp of a 5-10 degrees over the course of the last week or so before I decided to move the jars in an incubator.

You hit the nail on the head with this comment sir! I did notice the verm was packed a little to tightly on a few of the jars and I am using the tall skinny jars. Here are a few pics of the pinning jar. I'm hoping the stuff in the green circle isn't slime but none of the other jars have it, so it makes me a little worried. Thanks for all your help guys!

Jars/bags/tubs/trays should colonize @ room temperature getting ambient/indirect light.

Main pinning triggers are full colonization, FAE and Evaporation off of the substrate.

Light is a secondary pinning trigger. For tropical species temperature is not a pinning factor.

P. Cubensis are a tropical species. You could colonize at 70F and fruit at 80F with great results.


Light has been proven beneficial during all stages of mycellium growth. Mushrooms like mammals have a circadian rhythm.

You want ambient/indirect light(on a 12/12 schedule preferably) for colonization and consolidation.

You want direct/intense 6500K light on a 12/12 schedule for fruiting.

Optimal temps are mid 70s throughout the whole grow, but anywhere from 65F-80F is acceptable.

Incubation is outdated/uneeded unless temps in the range stated above cannot be kept.

The inside of the jar is always a few degrees warmer than the outside because the mycellium produces heat..mycellium tends to stall at temps above 86F , and contams thrive.

Fruiting at cooler temps tends to produce denser, meatier fruits, while fruiting at higher temps will often produce hollow, less dense stems.

Yeah those types of jars are notorious for this. If you birth them now they will certainly contam and fail. The short widemouth half pints is what you want. This does not happen with them and they colonize much faster.

You can have success using those jars but you have to put the substrate in there very very loosely. They don't look contamed but I doubt they will finish as is. You may be able to save them by flipping them and giving them a good tap on your palm so that the substrate slides away from the bottom of the jar.

If you flip them upside down do not flip them back right side up! Once you flip them you have to leave them flipped because you have disturbed the dry verm layer. I have seen this work before but it is your call. If they are packed really tight on the bottom they probably won't finish no matter what you do.

If it was me I would flip them and mark the growth with a marker. Check it in a couple days and see if it is growing. If it is let it finish and birth them. If no growth after a few days you may be able to birth them and cut off the uncolonized portion. It is a gamble but can work
