Currently designing a grow room for a 2000m2 room, it consists of 40 gavita lights, I have 150L of dehumidification available, I’m also running 3x 4250m2/h box fans for extraction of air from the room, my question is will I be having issues with heat from all these lights? Even though my outside temperature isn’t very high, I’m going to be able to pull fresh air into the room and exhaust the old hot air out, into a seperate room, what is the best cost effective way I can stabilise the temperatures in the grow room ? Especially at night because the place can get cool, especially during the winter, will I need to add heaters for nighttime ? Many thanks
