ANYONE HAVE ANY OPINIONS ABOUT THIS SUBJECT? THANKS DONNIE
Neither is nessecarily "better" then the other. Infact they are best used in conjuction: Reflectors to shoot down any and all light, mylar to reflect lost light surrounding the plant (better lower canpoy developement). But I only have one thing to say as far as mylar goes... DON'T USE IT. It's just another thing in the grow room radiating heat from your bulb. Bet use flat-white paint. It IS and always will be better :p
Sorry RastaKaza but you need to be a little more flexable in your thinking dude.
I use only Mylar 2 mil my self and hereā??s why.
One standard HPS bulb puts out 140,000 Lumens. If White paint reflects 86% light for most grows you only end up with 120,400 lumens reflected. Sidelight is as important as top light but all to much people forget it all together (unless it's SOG). You lose 19,600 lumens that is absorbed by the paint.
With Mylar you reflect back 98% of the light that hits it. So the same 140,000 lumens HPS light as before you only lose 2800 lumens so you get 137,200 lumens reflecting back. Thatā??s like adding a 150w HPS light for free. If you have more lights like I do then it ads up even more. With 6 1000 watt HPS light and Mylar you get another 100,800 lumens of light just for using Mylar. Thatā??s like the 7th light of 1000 watts is free.
Thatā??s why you should use Mylar Itā??s all in the math.
As for refelectors................
If you have an air cooled hood with glass there gerrrrrrreat.
If you don't then you are refelcting heat down on your plants almost as much as the light refelection and heat is bad (most of the time)
Spot on, spot on.
I must concur with this.Quote:

Hah damn looks like I'm off to get some mylar :) ... that's a interesting bit Z thanks. I read a ton on overgrow about measuring your grow room temp correctly and I was at 73 farentheit :o lol might as well hit er' up with some mylar. Where can I get a roll of it?
shit im really only near a home depot and all they have is this stuff.. http://www.homedepot.com/prel80/HDUS...gjk.0&MID=9876 is that mylar?
Rasta,
If you can... order some off the net. Do some comparison shopping to find the best price. I'm telling you, that Mylar stuff kick-ass. Way better than aluminum foil.
In my cabinet, I painted the walls white, then covered with 2mil Mylar. :D
whoops, sry dude, posted the wrong link.. http://www.homedepot.com/prel80HDUS/...rchResults.jsp that is that thermal foil stuff I think harddonn used in his room.. anyway id rather not have to order from another fucking website lol.. so zandor or anyone who knows plz tell if this stuff will do it...Quote:

Just make it easy if you buy a roll then make sure you get a wide one it's easer to deal with. 1-mil thickness is ok but it does rip easy.
Yeah. You can get them in the camping/sporting goods department. Just ask someone.
I was looking for Mylar and the Blanket idea too... BUT
The best of all is this. The Dollar Store for Mylar Wrapping Paper!! I picked up 6' x 30 something inches for a buck!. Spent 12 dollars to cover every inch of my room. That and a staple gun....done!
Check out your local dollar store first, with Christmas coming, they usually stock up on Mylar for wrapping. Make sure you get the metallic, and not the clear... they look the same, damhik. :thumbsup:
With the wrapping paper, you get a nice even coverage, and it's much simpler to apply than the blanket that's all crumpled up. 4 staples on the top, let her roll down, and a few more on the sides. Done!
Thanks Guyz, for the time being I've hung shoplites for two sides halfway down. I think I'll checkout the Dollar Store. Donnie
