Mini Greenhouse questions

[Parasocks]

Hi All,

First-time poster, long time lurker.

I recently saw this mini greenhouse and was thinking about purchasing it. Not sure if anyone has experience with something like this and if you would recommend it. It will be used mainly for orchids. I did see it this weekend and it seems fairly solid. Its ~$100

I have a number of different orchids mainly Phals, dendrobiums, oncidiums. I am based in JHB, so it is pretty dry here around 50% humidity here. I will keep this outdoors. We usually get clear blue skies in winter so light should not be an issue, temperatures are usually just above freezing at nights in winter and mid-teens duirng the day. I was thinking of installing a few small USB fans for some airflow.

Not sure if anyone has any opinions on it, or any advice on mods that i will need to add.

Thanks
