Consistently Successful

I have ordered these jars several times now and I've never had any issues. They always come intact with lots of bubble wrap. I even left a pack out for much longer than the recommended shelf life and it still grew me several flushes. I've never seen any kind of contamination and it really is a great mix for successful growing of many flushes. Highly recommend!

I hope package did not get too hot

Package was left on the steps in 100 degree heat. I hope the contents did not overheat. I understand there is nothing that can be done about the heatwave.
