Temperature?

What is the perfect tempertaure for growing?
What is the acceptable range in temperture for growing?

Good question wish you had gotten a answer. Have tried the search for this answer and get nothing. From what I believe it is from 65 to 85 F. I try to keep at the upper end around 80. But during the sleep cycle having trouble keeping above 65. I live in the north and can't help it sometimes. Good luck

From my limited knowledge a good grow temperature is in the low 70's farenheight.

I hear that the cab can get up into the high 80's before problems start and by the mid 90's plants can die.

Also, higher CO2 PPM allow the plants to grow in a hotter atmosphere without damage.

It is also based upon the strain of marijuana...

Also, temperatures in the low 60's or lower can impede growth.

i say like upper 70s lower 80's is good.

I agree with Pakalo my temps are mid 70s and low 70s at night, but 75 to 85 your good

indoor i keep my temp at 65 when veg and flower untill they start buding once they bud i keep it at 76, i was taught years ago never 2 go over 76, i control my humidity and co2 too, i guess everybody has there own way but i was taught temp, co2, and humidity are major and must be controled 2 a tee
