What precise temperature is ideal for Veg and Flower

[beethoven]

Hi all,

I've been growing a while now in a relatively cool grow space, around 72 lights on and 68 lights off...

Reading many forums and grow books, they seem to give a "range" from around 65 to 85 degrees.. That's quite a large range 20 degrees. Can someone narrow this down for me?

Thanks !

I like staying in the low 80s in veg and upper 70s in flowering.

Veg around 75-82 and in flowering i aim for 80+ at canopy level with LED lights.
With HPS upper 70 max. low 80 in flower for

Thanks all, I'm thinking somewhere around 78 will be a good starting point. I'll be rebuilding my grow space using AC infinity automated heaters, humidifiers, and fans...

Much success with it!
Insulating the tent or blowing air from the top to the bottom can also help to gain a few degrees, depending on the location and environment.

Let us know how it works out for you.

What is your goal?

Massive yield is done with hot and wet conditions, so you'll want to listen to the RH advice for 80F. *Lots* of decent flowers.

Massive quality happens at 65F and super low RH. Fewer flowers, yet super frosty and amazingly resinated.

No matter what flowering conditions you use, vegging in warmer and wetter temps will give you larger plants for flowering purposes.

Edit: No... unfortunately you can not have both. At least not with today's technology and understanding. A happy medium is definitely doable.

I keep my plants between 80-85 at the beginning of flower. When they switch from stretching and stacking to filling out I gradually lower temps.
