Ideal leaf temperature.

[Lucky Luke]

Ignoring grow room temps and VPD for a moment. What is the ideal leaf temperature to have?

Between 75-80f Is ideal, just make sure they are not more than 3 degrees hotter than ambient temps.

Agreed.

I usually see my leaf temps around 79 when my room is 82-3.

You grow with HPS? Under my QBs my leaf temps are usually about 6-8 degrees cooler. My room temp stays at 79-80 at the moment

No, led

Thanks for the reply's.
Seems there near perfect at 27c (80-81f). Running about 5c less than the room.

Great article!

Thanks for the article, my leaf temps are around 20C and I still see a few taco leafs. RH is 50-60. What temps might you expect to start to see hermies?

It will vary. Some strains like it cooler, indica dominate strains tend to lean that way. Sativas tend to like it hot. Since everything is pretty much a hybrid you just have to figure out what your strain likes.

Also co2 enrichment = warmer.

It really depends on the strain. Some purple strains would just end up green if you left it 79F.

I would try a few different strains in your "optimal" garden.
