Auto flowers no, but the set up won't likely work for a photoperiod.

Temp tent issue
Nice! Thanks guys for the quick help! I’m also kinda sort of having a temp issue, I’m trying to make it the best I can, I’m way down south and the temp reads 86-88 a lot. If I blast the fans and humidifier it does get down but I’m worried about the electric bill going up.

Humedad dentro del cultivo
The humidity is reaching 80% and even 90% in my grow, I've bought a humidity reducer that they sell at the supermarket, one of those that reduces humidity and has some stones inside. Will this harm the plants??

6" Fan in 3x3 Tent
I bought a 6" fan for a 3x3 Vivosun tent and I'm noticing a good mount of negative pressure even at the lowest setting. Do I need to get a 4" fan? There are some vents on bottom sides of the tent. Can I use those to lessen the pressure? Thanks!

Grow Tent/Room setup in the basement - dehumidifier or humidifier needed?
I’m planning a small grow setup in my basement and have a room that’s holding a steady 17–18 °C (62–64 °F) with about 55–58% relative humidity. My plan is to vent the exhaust from the grow box straight outside through an existing duct. Will I need a de- or humidifier? Thanks!

Ventilation set up
I just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?

High RH in flower
I find it really hard to keep the RH below 50%, especially at night when temps are low. I have a dehumidifier in the room where my tent is in but even when it's below 50% there, it still is above 50% in the tent itself. Can somebody explain this? Probably help me with a solution

Is high humidity at night bad for cannabis?
During day, I can maintain the grow room temperature to 75-77'F and humidity 55-65%. But at night, temperature raised up to 77-80'F and humidity up to 70-80% because I closed vents and air condition. Could this effect my plants in long term? Should I open vents at night also?
