Should be ok at around 40-50ish with 2 or so spikes per day. I use a vicks warm humidifier(w/out vicks obviously) one or twice a day for 15-30 minutes depending on my local humidity and I hand spray 3-5 times throughout the day also depending on humidity and temp, I free range in my sun room with the windows up most all day so my female can get as much natural sun as she wants so on hot days I have to mist more often and use the humidifier only once early in morning, as it raises the temp. Just find what works best for you. I've heard mist kings and commercial systems are the way to go I picked a more budget freindly option that works very well for now. Good luck and good vibes to you and yours.
