I,m sure someone else will correct me but I believe you need the temp around 75 or so and the humidity around 60

40-60% for humidity is desirable, but less than 40% is not necessarily going to cause problems. Get far past 60% though and you got to start worrying about all sorts of nasty stuff such as molds and bud rot.

As far as temps go 67 is fine, maybe a few degrees low. Is that the temp with the lights on and is the temp the same with the lights out?

Those cool temps could end up really effecting your growth rates. The ideal temp would be around 75. You are running 2 1000 watt hids?

How are you cooling the 1000w? Cooltube or reflector? Does the exhaust fan have a speed adjuster on it?

I have a 600w going and i vent my tent through the cooltube so it keeps it pretty cool. I just ordered a fan speed controller to slow it down as its getting a little cold for the girls.

For veg i like my temps in high 70s and flower low 70s. Humidity in veg i keep at about 70% and in flower about 40% - 50%

I just have a reflector, one of my lights is on a track but im not using that one at the moment, I have a 4" intake it was actually a fart fan for a bathroom that I installed in a window backwards and framed and insulated around it. For my out take I have a hole in the ceiling to the rafters with the insulation pulled out of one rafter so it can vent out threw there naturally since im forcing air in.

You might be in for some smells leaking if you have positive air pressure, Negative is better for keep smells where you want them.

If you was able to regulate the air being pulled through the room would be easier to adjust temps. Just thought.

yes. a dehumidfier is just an airconditioner that doesnt cool. ;)

a good a/c has a "dry" mode! 

But, if you have high humidity, take advantage of it (up to 80%). Run CO2 and a Sulphur Burner on Low setting (minimum burn time).

CO2 dissolves in humidity and is absorbed by the plant in greater concentrations.


High RH makes for mildew and mold conditions. Run a sulphur burner up to 1/2 way thru bud 2x a week for an hour when the lights are off
