Reflective vs white room for quantum boards

[CobKits]

Really? I thought mylar was just polyester (or another poly-something).

that shiny coating is a thin layer of metal i suppose, vapor deposition or something

i was just going by what Ed wrote in his book 30 years ago, but just found this

I had to laugh when GML complained when he wiped his mylar with bleach and it corroded.
He has obviously never seen what bleach does to aluminium foil.

Orca was the biggest waste of money I ever spend. Flat white paint works well for me and better than the orca.

The orca alternative im going to try is used to line bathroom walls.
Its wtaer proof, permanent, and costs 20 bucks for a 4x8 sheet

And it made a HUGE difference over the white paint i had on my floor .

Like the room was MUCH noticeably brighter

So after my run is done im going to line my walls with it

Has anyone ever tried it with mirrors? would that not be better

my first grow cabinet had those but that was 25 years ago and it was small

I think white would be best used under the canpy

Actually even regular mirrors work very well. I saw a comparison on another forum where several materials were compared and the mirrors came out on top.

Really easy to clean too. Cleanliness is an aspect people often forget regarding reflectivity.

Good point - back silvered mirrors would be easier to keep clean.

Mylar is a plastic with vapor deposited aluminum coating - very conductive.

What size cab, and what lights were you running? Love hearing about old grow setups!

 

[CobKits]

oh shit it was maybe 24x30"

i think we used T12s back then. this was 1994

 

[zypheruk]

back in the 80's well now can't remember at all what we used lol.

idk guys and gals, mylar, mirrors, tinfoil, got real trailer park round here fast. just saying, but have a look at the Grandmaster side by side hps / led thread and their setup and tell me the Mylar they have on the walls makes a positive difference. Shit is blowing around like a sail. Mylar creates hotspots, not the light source behind it. Sure I submit that LED has lower wattage's and therefore this effect would not be so pronounced with a QB vs HPS, but its the same reason people dont use tinfoil or mirrors, regardless of light source. Seems like this is a 20 yo discussion that was already put to bed. Flat white.

Mirrors are for sex, not grow rooms.

Flat white is the one of the poorest choices for reflective material.

"Hotspots" are nonsensical weed grower myths.

In 1994 weed was too cheap to consider growing it here.

Good thing they had safety tips at the end of the article. That 5th safety tip.....

where we lived in 1994 if you wanted real weed you had to DIY
