I had 2 large cultures of micro-worms,I read where you can put them in a fridge it will slow down thier growth and you can pull them out latter to use.
I had 3 large cultures I put in my fridge,they were in there for about a month,I could see no activity in the cultures,no wiggling masses.
I pulled one about 3 hours ago and split it into 2 smaller cultures,I put one back in the fridge and put one on the counter.
I just checked the one on the counter and I have wiggling masses again,the top is squirming with micro-worms.
If you have alot of cultures going,you can put some in the fridge for future use,just not the fridge in the kitchen,my wife would have had a fit!!
I imagine this will work for Bananna worms also.
My fridge temp. was around 36-38 degrees.
I did notice a little blackening around one edge of the container,I just took cultures from the good part,did not really lose much of the original culture.
Just thought I would share this.
