    Temp and Humidity questions fellas!

    What temperature causes slow growth? What is, too cold in ur Grow room? I think we all can agree 30c is max.. Anyways.. Does temp/humid have a big effect on growth? And what’s the perfect temperature and humidity in all stages? Does plant grow slower in flowering than veg? :joint:

    Temperature issues

    Just got my tent set up and the temperature is 18 Degrees Celsius. Is it okay to grow at this temperature? Using led lights so not much heat from the lights and don’t want to invest in a heater as they are very expensive to run, is there any other ways of raising the temperature?
