There's two different types of mylar I know of, one is really flimsy pretty cheap to buy at a £1.50mtr the other one is heavy duty thick stuff... Grow light or Grow Tite or something it's expensive £4/5mtr but it's good quality.
From what I've read about reflected light it's hardly worth spending money on if it's true.

You’re right. For the cost difference In white paint or white film etc versus the diamond film it’s a no brainer.
Flat white wins for the difference of about 2% more reflectivity lol.

There was a white material like film available when I was buying mylar, it tried to convince me that white was the best reflector but I still bought mylar.
Is that white stuff available now or did it flop?

As far as my research has been going in the last 20 mins, diamond mylar is the best. By almost 15%. Not taking cost into account of course

Mine is the thicker stuff so I probably paid the cost lol.

It's really going to depend on the size of the room and if you want to spend the money for a potential gain in light. But all of the large indoor lightied growing operations, cannabis and other crops in large warehouses just use white painted walls, floors, and ceilings. But on a larger scale the cost of the mylar would be ridiculous.

Why is it that almost every day someone joins this site and tries to show off their knowledge by answering a question from a decade or more ago? Do they think not being able to read a date will show people how good they are at research? Asking for a friend.
