I’m thinking since this cold weather is here my Temps. are too low. My set up I feel is maybe different than most. ?? Temps. are 67 ish to maybe 70ish. in my water. About the same in my canopy. Exhaust temp maybe 70 to 72. Which would be best heat the water or heat the air or both.
@Rusty personally I would keep my roots above 70F, the tops can tolerate much colder. You may have to insulate your reservoirs from the floor so they stay warmer.
Tanks my friend. U Da MAN
@Rusty when my lights off and its in the teen’s here my room gets about 60 to 62 as long as it doesn’t get below 55 you be good but if my room gets below 60 i will put small space heater in my grow
I put a few heating pads down. LOL So my question now is what is too high?
I try not to go over 85 in my grow but depends on your environment
@Rusty keep the reservoir water no warmer than 76…optimum is around 73 deg +/- 2deg …if your roots get too cold or too hot your plant will suffer in some way
