Temperature question

[cocojumbo]

Let's say that an ideal temperature for the greenhouse is 25 degrees Celsius for the day and 20 degrees Celsius at night and the humidity at 50.The my question is that we must put the thermometer in top of pot? or the top of the plant? or in the middle of the growroom? .wich poind of all this to consider the right temperature? same and humidity?

Check it at the top of the plants. Thats where its going to be them highest. 25 Celsius is fine for a high. You can go as low as 5 degrees Celsius and they will still do fine. If you get them down around freezing some strains will turn purple.

I have one just above the tops of the pots. I have one mid way up the wall. I have another that is at the same height as the light. You can have high temps up by the light, as long as the temps are at the desired temps at the height of the tops of the plants.

canopy level, thats where they will be most affected. ideally top middle and bottom. but canopy level is fine.
