This is beautiful.

You%u2019ve just saved me a lot of money.

By extension, these should work as petri dishes too.

I might do this for my first grow instead of using the mason jars. it seams allot more cheaper. and more effective.

I haven't tried this yet but i plan to do it with starbucks cups of the proper resin grade.

You can use 3 layers of aluminum foil as a series of lids.

I was doing this because i ran out of jars and want to keep experimenting, so this tek can be adapted easily to low capital situations

Followed the tech, let it be known that if Injector ports are a problem, you can use RTV silicon glue.
