What Range Should I Maintain For My Growroom Humidity & Temperature?

I am doing my 5th flower cycle. I have a 4'4" square by 7.5 feet tall flower area. a 600 W HPS light over head and 400W of fluorescent CFLs and T5 panels surround the plants for all over lighting. My temps get up to 82 degrees in day time with 40% humidity during veg and 85 degrees and 30& humidity during flower. I grow 9 plants at a time in soil and use a basic 3 part nutrient solution. Yield between 12-24 oz per flower cycle. Use root organics formula 707 and advanced hydroponics beginner basic nutes.

Everything I say is imaginary and simply for role playing purposes only.

Depends on what you have inside to equalize those cold temps. No matter what it is doing outside, you want inside temps and RH inside to be as close as possible to optimal conditions.
By optimal I mean that your temps should stay between 70-76 or so and RH at 60 to 80 for veg and about 40-50 or so for flowering... remember, these are approximates, your mileage will vary! :thumb:

I run an exhaust fan 15min every hour, it exits from the top of the room taking the hottest air out.

Now, the temps are under control at around 72f and humidity is around 60% in the flowering room. 60% is as high as I want it to go in there and things are looking much better with the temps down and the humidity up. Outside air is more humid right now and that helps.

I have used sulpher treatment to prevent mold etc but at this stage won't use it unless absolutely necessary.
cooking them!!!!

Hi all, I've just purchased a humidifier and have a humidity of around 80%+ for the verging stage.. Is this okay or too high? The only reasons that I can find this to not be desirable is down to rmitigating the risk of insects, bugs, mold and fungi. This thread is meant to be about humidity, but seems to have drifted to lots of other topics, specifically regarding humidity, can I get some input plead people about what are the perfect levee, risks etc. Thanks all

I run between 55-65% during veg. and 45-55% for flower (when there are actually buds to worry about).

I think 80+ is high. I would try to keep the humidity below 70 percent during veg. You can cover some of the air outlet with cardboard or something to reduce the airflow, that is if the unit is on low already. :goodluck:

40% and no more than 45% if possible during flowering indoors under CFL or T5s. Occasional rises into the 80s after watering at peak temp is OK, but not for more than an hour or so.

Also... DO NOT water during dark cycle. Only water at lights on or as close to start of day cycle as possible.

Everytime I have slipped up with maintaining these numbers I get a Powdery Mildew outbreak in my flower room. Veg room not as much cause of longer day cycles and higher avg temps.
