Humidity at night. Should I add a heater or...

dauntlessstarted grow question 4 years ago

Lights on day, my temps are perfect, and my humidity is 55-59% at 74-80 degrees F. Night, temps drop to the 60s and humidity goes up to 70-78%. Bought tiny dehumidifier to add, and I could also small heater. Is 70-78% gonna mess me up? Indoor/Outdoor And Winter is coming. ;)

Temps and RH do vary depending on lights on or lights off. When lights off temp should only drop about 10 degrees to prevent any stress. As far the RH at night problem you can get a dehumidifier to fix that. Hopefully I answered your question and remember Happy Growing and Free your mind one puff at a time.

I see your using a hps lamp which will keep your room nice and warm when the light are on at night you will need a heater to keep the root zone warm. 70 percent for a long period of time will hurt you end result might cause mold, mildew bud rot. Hope that helps

Hey guys. I have an air pump and air-stone for a hydroponic set but i decided to use a “smart pot” instead. Would putting the air-stone in the soil or directly under the pot help in any way?

High humidity in the morning I’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)

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?
