Everything is growing fine. Added a heater that has the option to run the fan only which works great. Temps dropped about 7 degrees C bringing the total to around 25-27 C on average.
Added some MG slow release fert in the soil (high in N)
Put up some more reflective insulation around the cab as well.
Also recently got myself a motion alarm. Going to run a wire to where I sleep with a speaker next to the bed. (pic of alarm in post below)
