Temperature

First post! Hope it's not a stupid one.

When you are monitoring temps how, and where, do you place the thermometer? I'm scrogging so I was thinking the canopy would be the right place. But do I put the old-school thermometer face up toward the light right in the middle? I guess maybe the best way to word my question is am I trying to determine air temperature or the temp the leaf experiences, including the light absorption? Make sense?

Thanks much! This place is so awesome.

I'm no expert but I would assume that you want to know the temp of the immediate area closest to the plants themselves since the whole idea is to keep the plants themselves in a certain temperature range. Like if the plants are at the right temp but the top of the room or closet or whatever isn't, then who cares right?

That's what I think too, but with absorption temps go crazy quickly. I don't know how comparable absorption of light is between plastic and plants. I have an Atomic Clock with a temp sensor (digital) and when it's out in the full sun it reads 125° when it's 85° outside. I feel like this is the same thing.

Use it outside in the shade and see what it tells you the temp outside is. Maybe direct sunlight is throwing it off

I have an indoor/outdoor thermometer that I use. I place the actual thermometer in the shade so that it can read ambient temps, and I place the probe at canopy level but under the highest set of leaves.
