Im building my second grow room and was wondering what everyone has used on the walls and floor for reflecting material. If certain materials yield different results? I need to cover a 6x6 room.

Yea, what Flam said. Mylar and Flat White Paint are prob the best. Flat paint not semi gloss white paint, Mylar can be a pain to hang up so paint may be easier and cheaper to work with. Aluminum foil will work but can cause heat spots and also use the dull side not the shiny side. just paint the walls black and youll be fine, who needs light reflection anyways. jk, you prob wont yield much

Mirrors and aluminum foil is out.

White or Mylar. Flat white it best, but any "white" is better than no white.

it's electrically conductive...
not a good thing for nit pickers that think it's a good idea to stuff it under the cover plate of say...the light switch on the wall...not that i would know or anything like that.

The best product on the market to use for reflective material for grow room or grow box is: kool seal elastomeric roof coating! It's everything you would want in a cheap and affordable reflective material.

Mylar is the most reflective of the above listed options. I did a side by side test of mylar and white panda. The mylar ended up giving me 5000 more lux at the same spot that used to be covered in mylar.

I wouldn't stay away form mylar, but I wouldn't go cramming it in your electrical boxes either. There really is no cure for stupid. Anyone ever use duraflect or ultraflect?

Ive never used mylar but ive never heard anything bad about it either. I have been using reflectix from lowes. Super reflective and it works as insulation too. I live in an older house so I need all the insulation I can get

Is that the bubble wrap kind of stuff? I had some left over and wrapped my hoods in it to see if I could lower temps even more by cooling off my hoods. Tis the season of running dual dehumidifiers so hard to tell.

Its duct wrap that is essentially foil covered bubble wrap. have we sufficiently beat this to death now? I use that stuff to cover the top of my ebb/flow buckets to reflect light back to the plants and keep the roots a little cooler. I'm rock star that way.LOL

That reflectix shit is sold at soooo many places under soooo many different names...its great shit from what I've heard. Someday I'm going to re-do my entire room ceiling to floor with it. Wish I'd have used it instead of mylar...reasons is this...its not just reflective. It is 4 layers of shit, one is reflective, another is a moisture barrier to prevent algae/mold growth on walls, a light barrier, and something else. Great stuff.

Foylon is the most reflective material that there is even better than mylar ... not to mention foylon is fire retardent and an insulator so you cant really beat that .. the list goes foylon , mylar , matte white paint , matter yellow paint, then foil at the bottom foil is only about 70% reflective but reflects alot of UV rays so its very unhealthy for the plants
