Sorry mate I missed the notification, I just seen this now as I’m going back through the thread:
yeah they’re pretty decent. They have loads of products too. I’ve used the blocks and the gel and rubbed it into my extraction pipes in the past but tbh if your carbon filter is on point then there’s really no need for this. I now have the Ona mister/diffuser and only tend too put it on if the tent door is open for an extended period of time or when I’m harvesting. They are VERY useful for the latter. I also got some plug in ozone generators that work quite well too, plus I got one those big ozone generators in case I get an emergency smell problem. But tbh, the most efficient and most safest of these methods is the Ona mister.
