hello sometimes my night temperatures (lights off but during the day) are between 73-79 degrees but when light s are on they are between 78-81 will this cause problems? grow space is about 14x6 with 1 8 inch inline fan for venting

Optimal Day Temp Between 70 - 85 degrees Fahrenheit, Night temperatures should be kept above 60 degrees to prevent stress. It is preferable during flowering to have a night temperature drop of 10-20 degrees to stimulate flowering hormones and reduce stem elongation. So no I don't think It'll cause problems

awesome! thanks for the responses guys i really appreciate it, its only that high of temp for prob 2-4 hours tops when the lights are off (otherwise its around 70) i was really worried but hearing this takes a load off my chest!

just to be clear

78-81 when lights are on (canopy level)
anywhere between 62-78 when lights are off

these are ok temperatures correct? sorry very new to this just want to do things are correct as possible

chill bro..
I grew outdoors in west tx for years, we grew year round. last time I grew the summer was over 100° for more than 3 months. and they grew huge. we had a rare and early snowfall hit my seedlings and they made it fine
I've only killed 3 plants ever, and my own fault

just make sure they have water, and give good airflow. it's not ideal but I just took a master kush that hit the low 100's for half its flowering. it turned out beautifully, and its still got it's purple

You should look into A/C.. Dry climate : evaporative air conditioner (50w a/c) (raises humidity). Humid climate : traditional window air conditioner (485watts for 5000BTU).

85-90 degrees will work but you should try to get those temps closer to 75
