Optimum temp for flower.

I have read the best temperature for flowering is 65 to 75 farenheit I have a my temps at 76.6 f when I have my light running at 600watts. When I have it at 75 % power (450watts) it runs between 72.5( today)to 75.2 (yesterday) depending on the temperature outside. Are those good temps or should I keep it at 450 watts? It's a 4×4 tent. I do run a air conditioner on the outside so that I can run a tube of cold air to our room.

Not to far off from a newb, but I know you're going to want your lights at 100% for flowering to get the grams/watt you want. And as far as I know 75 is a perfect temperature! If you're worried I'd run some a/c into the room and drop the temp a little!
People that drop temps to low 70's high 60's are looking to bring out the color of purple strains!

I run my a/c directly into the tent. When it's at 75% light it runs at 73.4 to 75.2. At 100% it is 76.6.

The 70's are a good temp for flowering but in all honestly, I have flowered in the 80's and 90's before, no issues but that wasn't in a tent. Just gotta have adequate airflow and watch the humidity.

Yeeee, I mean you gotta think this things a weed and literally grows anywhere and everywhere! You as the grower just gotta optimize conditions! How would you want to live a hard un sheltered life? Or a nice cozy life?

October in the southeast US is magical. Clear blue skies low humidity and the buds fatten up really fast. I would rather my plants do most of their flowering in October than September.

My first grow ended in November and I agree it really helped to have the temps and humidity taper off naturally since I was only using airflow rather than providing conditioned air into my tent.

I did have the power to move over 1300 cfm in a 4*4 area so that really helped me get through the summer heat.

I hit tempts as high as 92 and had no issues but agree with others 70-80 is your optimal range for day time temps and honestly I doubt you’ll see much difference going up a or down a bit as long as your within that range.

Indoor gardens are best suited for winter time. No risk of bugs, the outdoor humidity is low and the room provides supplemental heat for your home.

Or a hot ass desert climate! Lol

Wish I could grow outside but I don't have the space and too many neighbors and kids. I'll be growing through the winter. As I have auto flowers that I picked up for the next grow.

I feel this one! No substitute for the sun

My humidity sits 35% to 50% depending on if they have been water that day or not.
