I haven’t harvest at night time but this years crop will be! The alarm will be set for 4 am ouch ahah I’ve read somewhere, I tried looking for the link but can’t seem to find it now. But they say it improves THC and taste. I’m not sure about the thc but the taste and the smell makes sense. They say at night time the plant release co2, carbon, and surgars which would enhance flavour taste and aroma. But it’s worth a try right? Nothing to lose other then a shit load of coffee ahaha
