Shrink wrap vs. Parafilm 

I used simple kitchen cling film. I cut the roll into smaller rolls using a cutter knife and then used it to wrap. First I feared there's going no air through and the mycelium will die. But now I have mycelium sitting in my fridge 1,5 years later and it still looks completely healthy. I basically wrap it around about 3 times tightly.

Hey Gary, what I do is take a roll of cling wrap and cut the roll into a few mini-rolls. These are insanely convenient for wrapping dishes because you can just put the roll around your middle finger like a ring and wrap in a very similar method to parafilm (where you sort of stretch as you go), and then the cling wrap sticks to itself. One roll of cling wrap gives like 6 mini-rolls and each mini roll wraps a LOT of dishes. Give it a try sometime, you might like it. It's my preferred method.

Heat shrink looks like like a pain in the ass! Ya get in the zone on a parafilm mission😀

Thank you so much for this video! I've been looking online for data, exactly like what you just provided. Thank you again!

I've never heard of shrink wrap like this. I'm super intrigued.

Awesome lab. Nice.

🧙🏻‍♂️ High Gary, If its cool, i have a question for you an you followers (High buds) So I'm really curious about which tipe of Petrie dish do you & other people prefer ? 3 Vent or No vents Plastic or Glass Or does it really matter 🤔 Thanks, great Channel, content & educational 🧙🏻‍♂️

i'm still at the ketchup cups stage and i think they're great

Thanks for the content ❤

Very neat😎

Shrink wrap is usually Polyethylene (PE), which makes it immediately recyclable… BUT! it still has to seal properly and breathe.

You should do a video with grafting tape.. I currently use grafting tape, and haven't tried parafilm.. it would be interesting to see the difference.. Grafting tape seems like it's easier to use than shrink wrap, and you don't need the heat gun.. it's basically precut rolls of plastic wrap.. the 1/2 inch rolls work really well

Good talk Gary. Mycology is going to get big in the next ten years.

Will these shrink bands work for 80mm Plates??

what a great timing! i've just ordered a couple rolls of grafting tape since everyone seems to use it to seal dishes i wanted to give it a try as a low cost alternative to parafilm. can you say something about grafting tape in particular? or is it similar to shrink wrap, as you've talked about in this video? thanks a lot gary, you're the best! mush love

The only advantage I could see will be to seal a bunch of plate at the same time (with a clean* socks shrink wrap), a whole twenty stack or more, only agar petri dish for later use. I feel it's useless to parafilm individual plate when I did not inoculate them, and time consuming!

Hi, I have a question, I'm trying to grow lions mane on agar, the recipe for nutritious agar that I used is this: 500 grams of water, 10 grams of agar agar gel and 15 grams of honey. and the mycelium of the lion's mane is very slow and always remains in the same place while the original sample continues to grow, forming the typical hair of the mother mushroom. what could I do?

Niceee, are the "145 x 28 mm" for 100mm plates? The amazon link recomends 165x28 mm for 101mm diameter very confusing :S

Gary, I would like to understand making Petri dishes and spawn. What do people mean when they use markings like P1? G1 i believe is Grain Master 1.. is that the first inoculated bag? Was the G1 made from a P1, P2, etc….. what does it all matter, or does it.. I would just like a better understanding of the importance if any. In the video you just did you transferred a lions mane plate; was that a P1 and did the transfer make the transfer a P2? Does the transfer over period of time loose viability? Would love to hear what you have to say on labeling practices. Thanks so much!

Hey Gary can you tell me what size dishes you use so I can use your link to order the correct size shrink wrap. I noticed they have different sizes. I will order both. Thanks for the experiment video.

no petris with micro tears?

Could the heat gun have stirred up some mold into the laminar flow zone? 🤔

🥇

hello Gary, I have a question - if condensate appears on the walls of the petri dishes, will it not be critical for growing mycelium? and yet, what do you think, I will not look excessively wild in the matter of mycology, if I am soaked in alcohol with 96 percent of the wall of chagka gt condensate?))

Can I use Grafting tape or Medical Tape?

I'm digging the BBQ grill grate workspace. How do you like it?

I'm willing to bet that the contamination came from human error and not from either sealing apparatus function poorly. I appreciate the video however

Parafilm...this is the way.

I use grafting tape cheap and 1 roll will last yah a year lol

Where's the tag line?

Okay I'd just like to point out that how he's working making transfers is piss poor. He should know better to only work side to side and I believe that's the reason for his contamination. I don't wear gloves and I made my entire flowhood from parts from lowes. There hepa filters and everything, other than the blower and I've never had that many plates contam on me for such a small run like that. I guess it doesn't relate to the video much but it was cringe none the less. I get made fun of all the time for not having the proper filter and the amount of contamination he just displayed is what I got after 3 months of using it. Also maybe raise up your petri dishes a couple inches. Sorry people I like this guy a lot but like what are you doing man?

Absolutely ridiculous, one needs a heat gun to do this ? I don’t see anyone else doing this. Grafting tape is what people are using these days if you want to save money. Do your research folks and you will find the majority of people are using Grafting tape with 100% success.

I love your videos but the way you pronounce Agar it cringes my whole body lol. There are augers and there is agar. Not hating FYI. Has anyone else mentioned the way u pronounce it?
