Just a quick question.. Can you use a resealable injection cap on these? I am curious if there needs to be gas exchange or any fresh air...

for anything that is going to grow, It needs gas exchange. IF your going to put a resealable injection cap, you should make another hole and stuff poly fill in it.

Knocked up 3 jars today using this tek. Jars are a yellowish brown after agitation and I placed a second piece of foil on the lid to cut down on contams hopefully. Incubating now at around 78 degrees. I'll definitely post my results.

Wrong. You want none instead of two. If you seal the jars with foil, how's there going to be any gas exchange? Use either micropore tape over the hole or stuff polyfill into it. If you want an additional barrier you can use a coffee filter held in place by a rubber band.

I could be wrong and I'm not trying to contradict you, but putting foil over the top of something doesn't make it air tight. If so, how did my PF Tek cakes get gas exchange. Same seal. I deffinitely replace the top layer of foil with some poly per your suggestion. The hole is so small it probably doesn't NEED a filter at all. I just have had issues with to much fresh air durring colonization. Like with my mono. Thanks for the sugestions.

Ok, you guys are off track.
The question was about storage in the fridge. You don't need or want any gas exchange there. It's also fine to use a sealed plug or whatever. But it is a waste of time and money. And you might get problems with pressure buildup, which can cause air to get sucked into your jar contaminating it.
Always use a foil cap over everything you do. It's standard practice and it's there to prevent contams from falling into your culture. It's not airtight.
As far as gas exchange in any LC... It's not important. Your culture depends in the dissolved oxygen (DO) in the liquid. It doesn't really matter how much air exchange you have, it won't change the DO level in the liquid. Stirring, swirling, or aeration/aspiration will increase the DO and allow you to grow up a much thicker LC. But it's fine to just let it go with what's in there and then referigerate it. You don't need it to be very thick, and it is a lot harder to suck it out when it's too thick.
The easiest way to do these LCs is simply drill a hole in a jar lid, fill it, and put foil over the top. Then sterilize. You don't need plugs or filters or any of that happy horseshit. The foil keeps contams from falling in and keeps the whole top clean.
The only time you need plugs, filters, or the like is if you have some sort of situation where you can't keep your jar upright or it has to be placed in a really dirty environment.

Useful thread bump. (if it's not stickied... I come here from bookmarks, so I have no idea).
Anywho, just to add... some people are talking about how honey is expensive and how Karo is cheaper, but how honey works better and they wish they could use it.
Well, next time you're out and about, and you drive by a KFC or Bonjangles, stop in... get a glass of tea or something, and look around or ask the person behind the counter if you can get a few dozen honey packets. Most of the time, they'll just hand them to you or they'll be sitting out for the taking. Free honey, and it works just fine for starting LC.
Basically any place that serves biscuits will also have honey packets or dipping tubs. Just check around, free is always better because, hey... free, duh.

Hummm I was doing this LC last night... and I was smoking some really good grass. I sterilized everything up and I use alcohol to clean my hands while I'm working and to clean the things I touch. When I grabbed my LC bottle I noticed it was still warm so I covered it with a napkin, soaked in alcohol, in my glove box. I had a candle going for sterilizing the needle and all of a sudden it all bursts in flames! All my lab is burning like hell! HAHAHAHAH
The good thing is I've received training to put fires out so it was all over in seconds... I know it sounds obvious but never use a flame near alcohol... it doesn't need contact. The vapors are a lot more inflammable.

So I tried this method with a good spore print that i had taken myself on a piece of paper, then folded up and put in a ziplock bag. It has been two weeks and both the jars I tried have no growth whatsoever. No contamination, no myc, nothing but honey slightly clumping together. But this can be put back into solution with a quick twirl of the glass. It has been at about 74 degrees in the dark for this time. Any advice?

Correction. I do, in fact, have growth... I think:

Yea... I think so... after it is shaken lightly to break up the clumps. But there are clearly tiny spiderweb-like filaments. It is pan subs. Good or bad?

I don't see any growth... maybe there is...? My LC was ready in one week. A big disform white mass at the bottom. It was Pan. Cyans.

Yeah this tek works great! Though I found using less honey works better.

What temp did you keep it at etc.? I will be trying Pan Cyans very soon and any tips would be helpful.
