Ultimate ½ Pint Substrate Jars (12-Pack)

Great products

I’ve ordered a ton of supplies from lots of different companies.. MGK is hands down the best.. and there is no close 2nd .. The grain jars are better then ones I make at home .. amazing prices also .. I’ll never go back to anyone else

Have had success with all the jars i have purchased!!

Received on time

This is my third time purchasing these, and they always work well.
