I too believe that it is healthy to have temps decreased at night. But feel free to test and don’t forget to share results :slight_smile: .

Personally I’ve got best results with day temps around 23-25°C (73 - 77°F). Adverse effect (slowed growth) I’ve observed when going under 15°C (59°F) or exceeding 30°C (86°F). Its worse with aero when roots are not kept in safe of some dense material.

Good luck! :thumbsup:

Sorry I miss read the topic so I deleted my post.

Ok, i did some re-wiring tonight. Here is where i settled. Lights on temps are 76-77f and lights off are 69-70f. 30%rh in flower room, fluctuates to 39%.

Sounds good. If you would forgive me the nit-pick, I think sixty five would be my choice, but it isn’t going to ruin your grow.

I have a couple pure sativa in there, and am going to see if it will shorten them a bit. The weather is about to change also, so will be changing things up a bit. Going to mount a larger ac unit under the floor.

I think your good. I wouldn’t do anything drastic unless you were planning on it. Those are good temps.

I have plans to install a larger ac unit before summer. The one i used last year, just could not keep up. I have them mounted under the floor, and plumbed into the room.

@MysteryMoog did you complete a run with higher “nighttime” temperatures? I’ve read the same thing about stretch and warm dark periods. Greenhouse growers call it “negative DIF” I think.

I’ll jump in here, since the thread is about grow room temps

My cab can comfortably sit between 78-82 F with a RH of 30%
Don’t know about lights out temps yet, i’m on 24/0 till I build my new light.
Is that good enough to grow the good stuff?

35

I think your temps are fine.

At 30% RH, you won’t experience but rot.

I believe cooler night temps will help to purple some strains.

36

I have not. I have everything going well n dont want to fuk it up. I have far less time right now. Also will be moving the room to a specificly built spot in my house.

37

Definitely going to want to follow the new grow space MM.
