What is the acceptable range of temp for plant tissue

@dbrn32

I know I told you this before,

You presented it to me as a question not a statement and got me confused lol

[tdubwilly]

So I just checked my leaf vs. Air temps after two hours of lights being on and my top leaves are about two degree cooler than the Air temps @hoppiefrog however i got the LEDs

[dbrn32]

I would have to look, and I really don’t feel like it lol. So I’ll take your word. Maybe that was the one day I didn’t really feel like busting your balls any, so I threw it out there and figured you could take what you wanted from it.

If I was running your grows, I would be running canopy temps higher than you had been. Fair enough?

Probably lol

My air temps right now

When i was down there earlier canopy temps were at about 78

[dbrn32]

It’s been a while, and I didn’t quite have the controls that you did. But I think my fan run at minimum speed setting around 78f, and full speed around 83f. It would ramp itself between there to some extent. That’s where I felt I had best results.

Duly noted

I’d imagine you could replicate the warmer leaf temps by adding IR to a LED’s array.

[dbrn32]

I think you would need a lot. From standpoint of cost vs what you’re getting, i feel like it makes more sense to run your space a little warmer. Maybe not as much in cold winter months.

Relative quantum efficiency of like 720nm is still about 20-25%, so there would be some justification for those capable to have some. I just struggle to see point in making led light more hps like when it appears there is easy solution.

[macgyver_stoner]

No argument there, just thinking aloud about different ways to get the results we might want.

And I agree, the most efficient/least expensive is always the way to go, as long as it doesn’t skimp on safety and performance.

So @dbrn32, I assume you want my leaf temps to be higher but not necessarily my air temps??

Obviously if you don’t care what my air temps are then I can find a way to increase leaf temps but if air temps need to stay the same and leaf temps only need to rise then I don’t know how I’m gonna accomplish that

[macgyver_stoner]

I think he is saying, the easiest way to get your leaf temps up is to let the air temps go up as well. Instead of spending a ton of money to try and make your LED act more like a HPS with all the extra IR HPS produces.

room temps around 80-82 Leave surface temperature usually are 78-79 degrees usually check later thermometer It’s always more accurate then with then the Wall temp meter

You ok there bud? LOL

[dbrn32]

That’s what I was trying to say.

Based on my understanding of the area, seems like less expensive to just run the room a little warmer than he has been. And that also should move leaf surface temp closer into ideal range.

[tdubwilly]

Oops, not sure what happened there

Easy enough

Hahahaha lol funny
