Nice yea I hear ya on that its a constant struggle! i just got a sentinel fuzzy logic controller it was pricey but damn this thing really lets you dial your environment, co2 ,RH ,daytime temp, night time temp and all in one device I love it! and it never waste co2..Blacklips.....have to get a fan control to make the room work to its max or it will just vent the co2.I think i have enough air changing in the room now to keep them happy we will see.but my temps are down and i am happy.
