Brilliant info Don, always appreciate your detailed explanations, makes alot of sense though, i guess some strains are more tolerant to heat during the flowering stages but some that are used to flowering in more colder temperate climates tend to not like it.
Very keen to get two dimmer switches on a thermostat for my next run though, DIY mission, one dimmer on high one on low or even better a thermostat that can automatically dim and heighten the speed of the fan by %.
To increase your brix level does this mean that you need more diverse organic material in the garden? Respect bro
