Hey everyone, just wondering if anyone knows where to buy mylar. I'm starting a grow hopefully next week and need it before i can go too much further building my box. Thanks for the help.

Don't buy mylar....
Mylar works, but there are other types refelective material you can get that is more efficient.
I use panda film. It's white on one side and black on the other. The white acts as your reflector, and the black helps fight mold & mildew.
Plus, when cleaning your grow area, you should spray down your walls every so often. When using the panda film it doesn't smear when you wipe it down. Mylar leaves smear marks.
Plus, mylar creates hot spots in your grow area.

You can buy Panda film at just about any Hydro shop.

Cheapest solution is wrapping paper. Just make sure its the light aluminum type and it will work just as well as mylar.

I found mylar is a pain in the ass trying to put it in a box, especially if its a rubbermaid grow box. I ended up ripping it off and painting it white just after my first grow.

Yea, Ive used mylar on grows before, and ive found that flat white is just as effective if not moreso.

You should be able to find mylar at a hydro store if you have any, otherwise im sure you could find it somewhere like Michael's craft store or something.

Im using a cardboard box so im gonna need somethin that wont create hotspots and somehow fuck up my box. Also, i need to find a way to mount an exhasut fan near the top of my box, but im having trouble thinking of a way to support the weight of the fan... any ideas?

PC fans are light.

Yeah ive read about people usin pc fans but idk how to wire them to a power source and i really dont want to mess something like that up and start a fire. Also, this may be a stupid ? so i appologize ahead of time, but is it possible to have too much light im starting out with only one plant and i plan on having as much as 10000 lumens on this baby, one 80 or 105w on top and as many as 4 20w surrounding her when she gets older, is this too much or is there no such thing?

You can't have too much light, too much heat from lights is bad.
Wiring pc fans is simple. Get a phone charger of 6v or more. I get them at a 2nd hand store for $1-$2. Cut off the end, strip the wires. Plug it in and start connecting the wires, you won't hurt the fan and only one combination will work. Tape up the connection well and there's almost no chance of fire.
Good luck with your grow.
