First time grow box

[Orgniv]

I made this in about 10 minutes, it doesnt get warm but i'm still going to install a fan to get the air circulating... Just using small air holes for now

Noticed some browning on one of the leaves!

Any ideas?

Hey and welcome to 420.

If it's tin foil you're using for reflection - it's not the best idea, white paint reflects a lot more light and less heat.

Hope you get some plants in there soon
