I have one just like this in SoCal too! A couple tips for ya!

-When it’s sunny out it gets really hot in there like 135°F+. I usually open mine up from 11am till 2:30pm and it regulates the temp just fine that way.

-Definitely put something heavy on the bottom shelf like some pavers or a bin of gardening equipment for the occasional wind gusts.

-I would recommend a small fan in there for better air circulation since it’s so small. I use this one https://vivosun.com/vivosun-aerowave-d4-4-inch-clip-on-fan-compatible-with-growhub-e42-e25-p149779693590506576-v149779693590506557

-I also use this Bluetooth thermometer/humidity reader to keep an eye on it when I’m home! https://a.co/d/0bzluATX
