PC times for larger PF bags
    #14102693 - 03/11/11 07:11 AM (12 years, 11 months ago)

good morning all,

I have been working through my plans for my first cube run.

i have been doing shitakes inside using 3 or 6 lb shreadded oak bags in SGFCs. it works out good for me, so i was thinking of doing the first set of cubes in a similar fashion.

I was reading about making the large PF bags and would like to try this, as its almost identical to what i have been doing with the shitakes.

My fortified oak bags for the shitakes are coming to me from a friend who makes them for his shitake operation so i have not had to PC any myself. I get them already packed, sealed, and sterilized and inoculate them myself. then i let them colonize fully, dunk em for 18-24 and begin to fruit them in a SGFC with a vermiculite bed on the bottom. I have an air pump system on a timer with airline splitter to provide each SGFC with FAE.

I have a presto 23 qt pressure canner i will be using to sterilize the bags. the maximum safe operating pressure of the canner is 15psi.

i was planning on making the first round of bags at 3lbs of 2:1:1 PF formula. i will be using the exact same bags and injection ports my friend uses on the shitake bags he has been giving me. mycopath medium bags with self healing injection ports. I have an impulse sealer and will using it on the bags prior to putting them into PC.

I am having a hard time finding any information  regarding the proper time to PC a larger PF style bag to ensure proper sterilization. From what i have read on here so far i can safely assume a 3lb PF substrate bag would take way to longer to sterilize than 1/2pint or 1pint PF jars.

I was thinking i should run the bags for at least 1.5 or 2 hrs at 15psi to ensure the substrate is brought to proper temps all the way through the middle.

thanks in advance for any information.

Wild-ass guess, I'd say two hours or more.
Member named spongiform did a lot of big pf-block grows, you should hit up the Main Search Page and see what you can find out from him.
You can select one result per thread, sort by date, view posts by Trusted Cultivators or by a specific member.

oh for sure doc.

i am just now getting all my plans laid out out right now, but i will certainly start a log of the run when i get everything situated. i thought it was real cool how spongi did the crush and roll to speed colonization. i am going to try that with my next set of shitake bags to speed it up. I am very much liking that tek as its is almost exactly what i have been doing to my shitakes, except for the obvious difference in substrate material.

now to begin strain and spore research and select a strain...then its on.

Man i don't know. I made a few bags awhile back that were 6lbs and I did them at 15psi for 3 hours and they were perfect. The bags that went for 2hrs contamed real quick. What're you gonna be using as bags?

originally i was planing on using the mycopath medium bags but i was thinking on it as i was reading the spongi tek and will use get large size presealable gusseted spawn bags. i probably the ones with the B filter. im not really sure if the b or t filter will make a difference...any insights on that would be helpful. i will also be using the self healing injection ports.

using the large bags will give me the option of making them 3 or 6 pounds. i have gotten a few 6 pound blocks for shitake before and other than  size of the block, the longer colonization times and larger flushes/yeilds i dint notice anything else different from the 3lb blocks. thanks for the info on the 6 pounders. if i try those i'll go for 3hrs at 15psi.

Another option is PP5 plastic containers. Melt needle holes in the lid every few inches just like a pf jar.
I've used pints, but a big flat one would do a quart or more, probably pull half an ounce a flush.

"Any" size or shape is a stretch. But yeah, go check the dollar store. :thumbup:

PP5 plastic, check the triangle. Make sure the lids are too.
Here's some I did recently.
