Mylar vs White Wall Tents

[mlg]

Been browsing around hydroexperts site and seen the budbox pro tents with both Mylar and White walls. White seems to be more costly and in YouTube videos I've seen it reflects a lot more.
Any downsides in getting a white walled tent? First one I can think of is keeping it clean?

For the amount of difference it’d make id just go with whatever is cheaper.

From memory, the semi-gloss white spreads the light and heat out more evenly than (on the roll) Mylar. Even recall something years ago that the mylar can even create hotspots in the grow area, though i don't know how much truth is to that theory.

Whereas, the Mylar in a tent lining these days isn't as shiny, and has dimple's in it. I'm of the opinion they probably done this to address the issues of the Mylar of old (Mylar roll).

Maybe the dimples like on fluro lights," diffuse" the light and spread it.?they seem similar patterns.

This article suggests diamond (I am guessing is the "dimpled") mylar is superior to matt white because it's directional https://migrolight.com/blogs/grow-l...r-silver-mylar-the-best-lining-for-grow-rooms

yes this is pretty much how it seems to work!

Yep, Matt paints absorb light to some extent because they lack reflective properties like Gloss or Semi-Gloss paints. Probably why he didn't compare it to the gloss paints, so he could get his desired results.

You happen to be the very first article I have read saying mylar is more reflective. That may be the case with hid lighting but with led that is not the case. Not to mention white dissipates heat better than mylar. A study recently done through Purdue university was able to create a almost 100% reflecting white paint that hit the Guinness book of records. I think most will disagree with mylar being more reflective with the new age of grow lights.

now I'm curious if anybody has ever tried using that reflective paint they use on roads in their grow boxes haha

Haha, first thing that comes to mind is whether the spectrum as been altered once the light has reflected?

A few huge white road signs on the Highways might start disappearing.

A white tent will reflect more of the par watts that a mylar tent will. Par watts is the useable part of the light spectrum that the light produces.
