Doubled yields; CHECK, Decreased potency ??? BUNK / Urban Legend

I assume this report was generated by someone against the COST of C02 tanks/generators. As the author states below, if true, the minimal percentage would be unnoticeable to the consumer, and only detected by a laboratory.

Many growers destroy their harvest (and potency) by improper curing and harvesting too early or too late. Blaming C02 for any quality failure is ridiculous.
