Welcome in the club and good luck with this grow.
If you keep on adding pictures and comments here, I am sure many will comes to comments, answers your questions and give you some advice.
Here is the first, totally free of charge
I would suggest to make a bit more distance between the wall and the back of your Grobo.
There is 2 fans in the back panel and they like a bit more fresh air and there is also a 3rd fan, under the wooden lid, blowing the hot air out. From the back also, so this draft of hot air could go back inside if you are too close to the wall.
Hope you enjoy the ride
