Indoor Optimal Indoor Growth Air Temperature

[onenesssss]

Hello guys,

Would you please share your knowledge and experience with me? I started 3 feminized autos Northern Light Blue on 11/09/12, it is my first indoor grow. Have a book written by Jorge Cervantes "Marijuana Horticulture The Indoor / Outdoor Medical Grower's Bible" and on page 319 he mentions that "under normal conditions, the ideal temperature range for indoor growth is 72 - 76 F (22- 24 C)". I have been trying to keep the temp to that level, but a friend of mine (more experienced) suggested to let them go up to 32 C. Now, Cervantes says that "daytime temperatures above 85 F (29 C) or below 55 F (13 C) will slow / stop growth". What do you think about that guys?

Thank you very much

i would not go over 80f if i had to also co2 injection would let you go higher than normal

if your mate wants to counter guess jorge a very experienced grower in the field then on his head be it

on obvious one just go for the middle ground in the 70's there will be less shock when the light goes off if the temp drops to much

Thanks Agito,

I have just learned from another forum that indicas are good between 25 - 27 C ( 77- 80.6 F), whilst sativas are best to be kept in 22- 24 C ( 71.6- 75.2 F).

thought sats where from the equator so would they not be warmer condtions

That is exactly what I would have thought, that Sativas need more warmth than Indicas...
