Thread: mycelium stopped growing

I have ordered a Mushbag (rye grain) and innoculated it 2 weeks ago.
I used Equadorian spores i had ordered with the bag.
Two weeks have passed since i innoculated the bag, under very hygenic circumstances, and only a bit has turned white.
The bag is at my friends house in a shoebox, yet the temperature is not ideal i suppose since it only is room temperature.
Im afraid that the mycelium might not grow anymore.
I have put the box somewhere warmer today, [color:#D4C7C7]yet i want to know if the slow growth might have to do with the temperature.

Also i want to add that i havent opend the bag and only shaken it a few times to spread the mycelium. There seems to be no contamination and the bag is still sealed.
Hoping for your help

My mycelium always grew a lot slower than what the guides said. Last time I made cakes according to PF-Tek, the tek said it should become white in 3-5 days and after 7 days or so, you can fruit it.
The temp in my closet wasn't 27°C but it was between 20°C and 25°C at all times, and it took two weeks until the first jar showed mycelium, then it took like another two weeks until all jars were ready for fruiting.

I think you don't have to worry, obviously lower temperatures can make things really slow...

btw. I bought a small 10W heating mat to speed things up. It's made for heating a terrarium and it wasn't expensive. I put it in the closet and put two old heat sinks on it (the type you use on cpu's) so now I have a small electric heating in there. It only draws 10W, but it makes the temp go up by 5°C in the closet, so now I can keep it at 25°C-27°C at all times.

No need to shake a few times that is just disturbing not helping. Shake ONCE and once only. Every time you shake the bag the mycelium needs 2 days or so to recover, in nature mycelium spreads just fine into glorious networks without anybody shaking things up. You are using spores not a live culture so it will take longer and 2 weeks is not a long time when using spores. Next time, I recommend making a liquid culture with some honey or malt and injecting that into the grain bag. That will be quick depending on temperature. Keep the bag in a dark place and for goodness sakes do not disturb it.

Is there any water accumulation at the bottom of the bag or or is the grain looking mushy?
