I'm thinking you should be OK, but I'm not sure about dropping below 60 degrees. Only those of you in cold climates usually have this problem. Most of us have trouble keeping it cool enough. Is this your first time dealing with these temps.? If so I'd keep an eye on them and look for symptoms of stress.

I know those temps won't be a problem outside. Hopefully, they'll do OK. The last info I can recall stated something like 65 to 85 is their favorite range.
grey1223 Reviewed by grey1223 on . Too Cold? I've had experience where temps below 70ºF slow growth a lot. My temps were as low as 70 during the lights on time but I was able to increase this by slowing down the fan and moving the lighting transformer close to the plants. But I'm sure the night temps must be 60 or lower. What is the acceptable temperature range for growing herb indoors? Thanks, Shovelhandle Rating: 5
