Decided to go one step further

[The Orchidist]

I now have an 8 by 6 greenhouse given to me as a gift ,,, trick was it had 200 screws ,lots of framework and no instructions. But after countless hours of scratching my head it finnaly came together , i just transition my oncidiums and some other species outdoors , i only have a small fan for now and leave it on 24 /7 ,

I went to hardware store and purchased frosted paint spray for the above panels to avoid direct sunlight , i am noticing wide array of temps in the house , and the base is pure sand ,as it once was a patio . I plan on setting up hydro within the greenhouse soon ,

I am not sure correct placement of fan or if i should cut out a panel and somehow mount fan blowing in fresh air. And one for exhaust,, what is best and No it has no venting , all panels are solid .
