Last April, after 30 years without plants of any kind, I ordered several orchids and
this mini-greenhouse. For about 3 months the orchids were in the living room under a dual head LED plant light.
I put the mini-greenhouse flush against the back door and cut an opening in the back panel so I can enter it directly out the back door. A Conservatory! I was not prepared for how hot it would get in the summer.
I knew light would be an issue,
A 70W LED light gives a lot of light, and I have had mine running 14hr/day till the present time. A number of earlier posts expressed concern with the amount of natural light the greenhouse receives. Mine receives almost none. I don't worry about it.
I've shaded the roof 50%, and the lean to location on the west wall of the house, and the property fence on the west wall of the greenhouse mean only a narrow window of Sun is present, from 1:00pm to 4:00ish pm in Summer. The temperature can go from 70F in the morning (with the heat on) to 80F at noon to 106F at 1:00pm.
I am glad Fall is here and the greenhouse heater (1500W) can keep the night temp at 65F and it is set to make sure the daytime high reaches 80F. Earlier this evening I decided that I am going to use Moving Blankets on all surfaces (including the floor) except the exit door to the HVAC compressor access. All light will be artificial for the duration of Fall and Winter.
