grow room made from space blankets?

Not sure if this has been done yet, but I found that space blankets are fairly cheap and large compared to reflective insulation, and believe its heat resistant as well. Could this work, and be good for indoor growing on the cheap?

Sure. I've seen a lot of people use em

Flat white paint would probably work better. That reflective mylar can cause hot spots. You want refractive, not reflective.

Okay thanks, I had this space blanket I got for free in an emergency kit, so I opened it up and was puzzled by it. Good thing I got it for free. Check out the picture. I ended up cutting what was good from it.

there made from mylar the same stuff from grow shops

there is a paint that has 98% reflectablity - it's a flat white with metal flakes in it

I've used those space blankets as a couple of walls in a bigger room. They're definitely better than nothing, but you'll want to upgrade when you can.

I used these blankets in my first grow not that long ago. And if your on a budget like I was these will work fine.
but I do say it was hard to flatten it out against the wall...for sure a two person job to hold both end to stretch out.
check out what I grew with a 400w and blankets...

I have to ask you to explain your theory on hot spots from mylar....

I ask because my entire room ( walls, ceiling,floor) has been reflective for almost two years and the only hot spots are the two 600 watt bulbs hanging above the plants. My theory is that the reflection of a bulb is in no way as hot as the light coming off of the bulb its self.

It is simply one of the many myths you read about on the grow forums.

And yes... Flat white paint with titanium pigment added is the best choice!!!

Black and white poly is much better in my opinion and not expensive compared to trying to line a whole room with safety blankets.

Because anywhere its not evenly reflected it can change the foucs of light, createing a "hot spot".

I get what you are saying but again, the bulbs are the hottest spot in the room! You know that reflector above the light is creating the hottest spot bar nun. It is designed to "focus" the light on your plants!! How do your plants like that??

Hot spots are a myth!!!!

I started out using mylar blankets and would adjust them in order to reflect the most light possible towards the plants. I got tired of the fans blowing it around and switched to 1" rigid insulation that has foil on one side.
Because my entire room is reflective the lowest leafs grow sideways and upside down collecting the light from the lower walls.

Plants love and need light in order to grow. The more light you give them along with not removing valuable leafs that are there in order to absorb the light the better they will grow!

Remember.... The leafs absorb light using it to create sugar that is sent to the roots. this sugar is then used by the roots to convert the good stuff in the soil to food for the plant. The roots do what they do and send the goods up into the leafs where it is stored until the plant needs it.

The more light you have bouncing around in your room the better!!!
