No Colonization on Bottom Of Jars?
    #1409953 - 03/25/03 10:19 PM (13 years, 8 months ago)

It seems that the bottom of each the jars will not grow mycelium, maybe because the weight of the cake is not allowing it to grow on against the bottom of the jar?

He took a couple of seemingly fully colonized cakes out for fruiting and there was still some substrate, from the bottom, that had been left un-colonized...

Does anyone else have this problem too?

Thanks....

Like Lotus said, flip the jars over. Mycelium growth will tend to slow to a snails pace towards the bottom of the jar due to lack of oxygen. In some cases, stunted mycelium growth is due to excess water in the substrate, or a lack there of. So if flipping your jars over doesn't do the trick, try to determine if there is too much or too little water in your substrated and modify your ratios the next time you mix up your substrate.

Yes flip it over. This is a great tip!

Also make sure the holes on the jars are open. I like to let the myc start to grow then take off the tape. The dry layer of verm is there to stop contams. I add a coffee filter to make myself feel better. (thanks to Skikid16 for that idea)

When the jars are about 50% colonized, you can take the tape off to get some gas exchange going, and flip the jars over. Tap them a few times first to slide the cake toward the lid and make room at the bottom of the jar for the mycelium. By the way, some people don't use tape at all with good results since the dry verm on top is effective at keeping out contamination.

If you do this, you should completely remove any uncolonized substrate before you put the cakes in your fruiting chamber. Leaving uncolonized substrate is an invitation for contaminants.

Good luck!

If you want to get rid of the colonization "stall" at the bottom of the jars, all you need to do is put a thin layer of vermiculite on the bottom of the jar before throwing your brf in there. It will colonize much faster this way. It is called the "Invitro Double End Casing Tek"

Hope it helps =-)
