I'm with Flockshot and gbauto. I have seen reflectivity charts and FLAT white paint is just a notch below the best reflective materials. Being a cheap SOB, I built my grow area with plywood so painting it white was easy. Be sure to use flat white if you decide to go that direction and it's easy to keep clean.

tyler_ hobbyist do a forum search on reflectix. i've been recommending it ever since i discovered it...in fact DingusKhan just used it to do some things in his space... it's cheap, rigid but pliable, reflective, insulating, can be cut w/scissors, etc. i have never used foil or mylar but i think reflectix would be an upgrade over either of those. plus i've heard that mylar is hard to keep clean..."i try to play the ball not the opponent."--Roger FedererComment

It would be the same difficulty to clean as mylar, though. I bought a 10pk of mylar space blankets off Amazon for about $4, and I've used 3 or 4 of them. They are light, easy to make the size you want, but it's very flimsy, and if you don't attach all of it to the wall, it can billow up and blow around with your fans blowing on them. Who know what they might get into: cover plants, get in your hot lights (fire hazard). BTW-not all mylar or space blankets are flame retardant or non-conductive. -
Reflectix is much easier to keep clean than mylar sheeting I can tell you that, I have it insulating all kinds of stuff and it has a flame point of 600-degrees if memory serves me correctly, I looked it up on the package a couple of times. I also know that Reflectix does hold up to being wiped down with water, but I am not exactly sure what I got on it one time that made the mylar coating come off a small patch of it, otherwise unlike mylar space blankets it's held up to 4-5 years exposed to everyday traffic being used to cover insulation and it's performed really well stapled straight to the wall. Its two separate layers of bubble wrap and I think there is a 3rd inner layer of mylar between the two layers too, I was looking at it really close recently and noticed that. -
i've had no difficulty cleaning the reflectix. in fact the only thing that seems to have any change/removal-of-the-outer-layer affect on it is duct tape. i have peeled both scotch tape and packing tape off and on easily, reapplying where wanted and had no effect on it whatsoever.

Has anyone ever used plastic sheets, like the stuff u put on ur windows in winter? That's what I'm useing at the current moment because I'm in a huge space and only need a small area I have noticed it being reflective but does anyone know if the plactic is useful?Comment

Yes I actually have as I stated in a previous comment above recently, the plastic does great to allow you to make something air tight fairly easily with the double sided tape, I've made humidity areas with it and created basically a plant tent so I could control the area of the temps, humidity, CO2 in a smaller set area, but the entire area was light tight and on a day-dark period together so it wasn't a big thing when I did it. I had specific areas of my indoor garden such as roses I needed to keep warmer than other plants, and others which required higher humidity than others, so I used that plastic and space blanket mylar to do everything from create different temp-humidity zones for plants in the same room as well as to insulate the outer walls to control cold or heat seepage pouring through to offset what I wanted in the room.
I learned that if you want the light to go through the weatherization plastic such as in my case above, I would need to make sure I used the plastic that can be heat shrinked with a hair drier for the ceiling, which I just attached to a wooden frame and double sided taped it and used the hair dryer to remove all the wrinkles. Also learned that not all types of plastic sheeting is the same, I only ever had success with the weatherization plastic inside for my plants.
