I can’t find the one my friend got this for 500 bucks; that’s how I made a veg cupboard;
Don’t spend so much money get creative for blocking light; my wooden closet has gaps too; just cover with a curtain and you’ll be fine; directly light nahi aani chahi hey (put a suitcase on top hang a bedsheet)!
A few of these, hung over a line or two will provide instant shade and help your AC keep up. (link)
