What Temperature is optimal for a soil grow?

[Immune]

Similar to my other thread I'm wondering what temperature you guys think is the best.

I've been using 70-75 with co2, but after some reading maybe 80 - 85 would be better.

While I by far am no expert on growing, IMHO I think the 'preferred' temperature/condition for cannabis is 76-78F @ 25-35% humidity. Not sure when you start adding co2 to the equation, I never really saw the use of such a thing unless you have a massive grow and there is a LACK of co2.

With co2 you should be at 85 degrees....

25% Humidity thats insane.. With co2 85 is a good spot, and 60% humidity early in flower later 50%. You will not see the benifits of CO2 in soil as you would in COCO , Rock Wool etc.. But it will help and increase yield and finish time just not as much as hydro.. If your going to give info atleast have your info some what close.. JACK

I was going to say 68F/20C till I saw CO2. I don't do that so I'll bud out.
