They're not petri dishes but they sure look like them I cook them straight in the pressure cooker they work fantastic I do put a small hole in the top and cover with micropore tape before I cook them up

There was a guy recently who bought PP petris and did a little write up.
Only downside I can think of is they are small, 50mm while most disposables are 90. Which is adequate 90% of the time considering many people use 90mm dishes with 3 or 4 segments and they will probably cloud a bit with use which isn't the end of the world, if you get 3 or 4 uses out of them, you have saved money over using disposables.

I've got 4 cases of pyrex petri dishes(48) And tried various no pour TEKs
And I still go back to using 100x15 disposable polystyrene dishes. 2-3$ for a sleeve of 20. Can prep agar sterilise it cool it down and pour a sleeve in a SAB very quick and easily.
Last link in my signature first link you find there.
All the agar work I have ever posted was done in a 66quart tote SAB
Doing pour agar is as easy as ramen. Im mind boggled at why so many are adverse to doing agar especially pour agar

so you're telling me agar questions go in cultivation? what noob uses agar? don't be a dick...
He wasn't being a dick he was being helpful... And yes if goes on regular cultivation. Like the same place all the agar teks are. Agar is a simple and fundamental part of cultivation if you want to go past spore syringes and cakes. There's nothing advanced about it except that noobs are intimidated by agar for whatever reason

Your sterilizer/PC uses more energy than the mass produced petris. Let alone the water and detergent used to wash them out

Perhaps, but energy can be made from a range of sources - some bad, some ok. That plastic will not decay for a very long time and a good deal of it will eventually end up in natural environments like the ocean.

My PC uses less than a kW to hold 15 psi, and sterilizing petris does not take long at all.
Compare that to the 15 minute detour the courier van has to take when it delivers me a box of disposables and you're already using 10x that in fuel alone, nevermind all the shit that goes into making the petris, the cardboard box they come in could come from a factory 100 miles away, as could the sleeves, labels and so on.

so you're telling me agar questions go in cultivation? what noob uses agar? don't be a dick...
in fact, i know there are ways to do this i,e steam sterilizing for 90-120min... or a level three germacide for cold sterilization.... i am learning through experience and experienced both of those recently... i just wanted to know if anyone had PC'd them, would be much easier, but i see now the plastic melts. they are disposable, yes, but so is a water bottle and they get re-used all the time
The fact you have 24 posts generally says your a noob, peitri dishes are used by many new cultivators. Bottom line this thread belongs in general cultivation. Again proving my point mods need to change advanced to a minimum post count to start a thread.

The ones made of HDPE or polypropylene can be reused, the ones made of polystyrene cannot be reused easily and are truly disposable. Disposibles are best when doing a lot of agar work at once to save you on prep time. They are normally processed using gamma irradiation instead of heat.

dear hall-monitor:
the fact that you guys think life begins at the shroomery tells ME that you have not much REAL education. i have a degree in biology and conservation sciences... i have more lab time than i care to share... why is it that folks here think they are so special? i thought these forums were about discussion and sharing thoughts and knowledge... 24 posts means nothing. i have seen people here with thousands of CRAP-facepalm posts... post count doesnt mean anything. 6 years of secondary education does however... i have been on this site since 2003. made an acct back then but forgot the password lol.... so now i have this one... i am admittedly new to making my own agar..
you may be a teachers pet crybaby mu-fucka but you are welcome for the link to reusable petri's.... if the mods want to move this they can. it wont bother me. which brings me to my next point..... if you are so experienced why arent you a mod mr post count extraordinaire? answer me that. if you were you would have moved it instead of calling your mommy LLUULLZZ :p
in fact, i realize now this should have been in agar and cultivation... i was under impression that 'NOOBZ' use pf lol. i did.... IN 2003.... once or twice but that was it. coir or straw since then... i just cant get over ya'lls attitude. whats ya'lls deal? you may be experienced in THIS FORUM, i would advise a trip to the outdoors and some human interaction... seems like ya'll could use the experience....

Funny thing even the recluses of mushroom cultivation spend more time outdoors than 95% of the population because they're looking for mushrooms.
We have attitudes coming here for free helping people to grow better and produce as much as possible for their efforts. When the people in cultivation make you type long winded posts about how much everyone sucks... Time to take a look in a mirror.

lab time yes. not much culturing tho. just getting my feet wet with mycology though. i have sterile tek and mass spec experience... many techniques actually i am familiar with, tho like i said not much culturing, and most of what we have at the school labs were glass, so no i havent ever used crap styrene dishes before... i knew ya'll prolly had.... sometimes it helps to talk stuff out loud with others and you find your own answer... turns out none of you have experience with the same dishes i have either... your welcome for thos btw.... polyprop dishes are different.. so, actually i feel like i was in the right... they say microwave safe, but thats different than a PC//// so self-righteous this group here... not impressed.... but its ok. wondering why you all take so much time to berate people new to YOUR forum tho... were you mistreated as children? lol.....
and again...mazda has been here for 3 MMONTHS, and TC (lol at naming himself that but doesnt truly have the tag: poser.....) has been registered less than three years lol. ..... i been reading and practicing here FOR 12 or 13 YEARS, but yes, agar in my kitchen is new to me lol.... i hope the mods do find this and shit this down... its not fair or welcoming of these three fucktards, who are just as new as me here, to be condescending and crying about thread content when they have no stroke at all here.. kinda gives the shroomery a bad rep in my eyes....but you three are nobodies just like me, only i dont have a bad attitude, maybe yall should eat a mushy or two and look inside. just bullies think i will block ya'll///// that way i dont have to listen to dickdrips blabbering....
