Long time guys. Recently started growing again. About 4 weeks into flower and the humidity outside is really up and down in the UK. Lights on ranges between 45-65% and lights off ranges between 40-55% as I have an electric heater timed to switch on during lights off. Temp is 23 deg with lights on and i keep it at around the 20 mark with lights off. Can I still suffer from bud rot with humidity between these ranges?
