Outside Grow Closet.

Under construction 6' wide by 5.6' wide and 3' deep outdoor closet. Karachi, close to the equator, is pretty tropical with mild winters and hot summers so im insulating sandwiched panels on all sides, the top, and the front doors to keep out the weather...

It'll be under a shade, the house not too far from the coast, so im counting on the breeze to keep the area in and around it to about 30* max for most of the summer months. June and October however are going to be tricky as it gets pretty sultry, but i'm not too worried about the rest of the year....... Don't have a choice, it has to be outdoors...

Anyway, this is the layout, pretty straight forward. Would love to hear from you guys about any cooling options apart from the built in ventilation if needed, and also maybe some suggestions and feedback.

Thanks in advance!

You could dig down a foot or two and use the earth for a particially insulated wall and cooler temps. Or 5 or 6 feet is possible...

6 feet? A 'grow grave' then...?

I have to keep it on a tiled floor unfortunately, can't even go in an inch.

Not too worried too much about the heat yet though, the next 4-5 months shouldn't be that bad..
