Is epsilon really low odor?

Being an unstable hybrid the plants are going to be different from each other. To claim they all will be "like this" is a bogus claim. It's for the gullible to believe, and buy.

Not grown myself but I know a mate that has, he said the same and I have noticed a few comments about this also, there must be something in that, not sure

it may have the possibility of that trait, but no gaurantee all of the seeds display that trait. depends on the underlying dna that controls such things. If they didn't devicse a proper breeding plant to maximize that outcome, it's whimisical in nature. Like the process of ensuring an autoflower 100% acts like an autoflower... or whatever the percentage is.. it's a calculable probability that may or may not reach 100%... need the details to know.

Yes. I have a basic filter and it keeps everything at bay. Maaaaybe the last week before harvest u can have that mustyness popping tru. But mine went ok. Orion on the other hand was a lil more stinky.
