I havenāt harvest at night time but this years crop will be! The alarm will be set for 4 am ouch ahah Iāve read somewhere, I tried looking for the link but canāt seem to find it now. But they say it improves THC and taste. Iām 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 itās worth a try right? Nothing to lose other then a shit load of coffee ahaha
