Plastic Lids with Self Healing Injection Holes and Air Exchange.

[Dr.Hallucination.]

Here are a few Wide Mouth Plastic Lids I have turned into Self Healing injection Lids with an Air Exchange as well...I simply drilled holes,applied Silicone and Band-Aids,and let dry.These Lids do however say that they are not for processing,this is writen on the inside of the jar lid,The book Psilocybin mushroom handbook Easy in/out cultivator,does state that these lids are infact Autoclaveable.I am going to test these lids in the weeks to come and will post the results.If anyone has allready tried this please let me know ,and how well,or if they worked...Let me know what you think...

cool...but why bandaides?

is this for PF jars?

[Dr.Hallucination.]

The reason for the waterproof baindaids was because I dont have Tyvek,and also read somewhere that tyvek can act as a wick for contams when wet..If this is true or not,I dont know....?...?

[BuckarooBanzai]

Tyvek can wick. So can bandaids.

You want two layers, with a dead air space in between. That way, if one side gets wet and/or contams, the other side is still in tact and untouched.

Washers make great spacers for this. Check it:



Put one washer on top and one on the bottom. The dead air in between makes for a very nice security blanket.

Those lids are detailed better in post 4 of this thread:

Ill have to add the washers ,,Thank You for the Tip...

[Lazlo]

I tried bandaids once and they didn't work. The G2G jars simply stalled out. Then all I was left with was a sticky mess on the lids. Ack.

[BuckarooBanzai]

My FOAF has never had any complaints about two layers of post office Tyvek and washers. Keeps breathing even after multiple PC trips.

[malefacter]

you don't even have to use washers just use a thick bead of silicone

[Dr.Hallucination.]

Thank you for all the help on the subject, I'll put it to use.

are these lids being used for half-pint pf cakes?
if so, stick to the standard, 4 holes no filter lid.

only need the air exchange filter when doin grains.

[BuckarooBanzai]

Slight correction.

You don't need air filters on jar lids with open inoculation holes. You DO need air filters if you fill the inoculation holes with silicone to make self healing injection ports.

Edit: filters aren't critical, a hole for air exchange is critical (if you fill the inoculation holes with silicone).

[Hippie3]

pf jars do have a built-in 'filter'
under the lid

[ANON]

i've been thinking of using some plasticware that my mother gave me, which i have no use for, sterilizing them, cutting holes on the top and sealing tyvek filters on them as sort of mixture between a growbag and a jar. and then maybe fruiting them in the containers, or transfering them into a monotub once colonized.

actually, now that i think about it, i'll try both methods as soon as i get my PC and some tyvek. i have a ton of plasticware to experiment with.

[Dr.Hallucination.]

I got the idea from this tek. http://forums.mycotopia.net/showthre...hlight=healing (Self Healing Injection Port Jar Lids W/ Waterproof bandaids)

[dial8]

Did you rough up the lid before you applied the silicone? I found this out the hard way. Made ports in a plastic pp5 lid and as I was removing the needle after inoculation along came the silicone blob with it.

[Hippie3]

had that happen on a bag once too,
now i just clear tape over the port to keep it stuck on plastic

[Bobcat]

Have had very good results throwing down a piece of duct tape, then silicone. After it dries add another piece of tape. It won't be going anywhere. Especially after PCing- when the d-tape melts together and to the bag/cap.

[Hippie3]

not a bad idea there

[Killjoy]

Biggest problem I've found with plastic is it doesn't seal!
Likely Close enough for PF Cakes, but LCs don't fare as well.(and they leak)

Be careful with temps, I've melted a few dozen lids. They seem more prone to melt when near the lid, or the sides if you're using gas cranked full blast.

Made a set of lids similar to yours with metal seals glued inside to use for long term cultures. Had even more trouble with those melting after I thought I had it down.

Most of the time some of the lids will be loose after a PC run. Don't pick the jars up by the lid, they tend to fall off. Just re-tighten them.
Don't over-tighten before or after the PC. (especially after if they are still warm AT ALL)
A Stuck plastic lid can make a rusted-on metal lid look easy to remove.

I've found Athletic Tape a decent Tyvek sub, esp if your not into silicone, or like me forget about it until 15 min before and don't have time to wait for the silicone to dry. Survives the PC better than any other Tape I've tried, easy to write on.
It will wick so your still better off with the silicone seal.

All that, and I still like plastic lids better than Metal.
