New Grower WELP! Homemade tinfoil reflectors

[Dr Cannabis]

So I took a plastic pot, cut it in half, filled up the insides with tinfoil because I have no mylar.. But I understand that tinfoil can burn the ladies, so I put the dim side out and kept it as smooth as possible... Is this all wrong folks? Experiences with the dim side of tinfoil? Should I take them down again ASAP?

I didn't dare to have them up more than some 10mins, I didn't want to burn the ladies. So now I'm gonna paint them white on the inside instead. How does that sound?

Maybe try making the reflector out of cartboard and just stick the foil on the inside, or leave just the white cartboard reflector.
Make a pretty wide cone or parabolic shape and attach it to the lamp on a place that doesn't get hot.
Some holes can also be made to allow better heat management(if needed).

when I have had to make reflectors in the past the method I used is to take a large can of beer, cut it down the side from top to bottom then cut off the top and bottom parts of the can.

you should be left with a rectangular piece of metal. flatten it and you will notice the inside is highly reflective.

I took two of these sheets and bolted them to a metal rail to hold them in place. I used the running rails from an old kitchen drawer I found. I also bent the rails slightly so I got a nice curve to the reflector.

in total it cost me £1 for the nuts and bolts, the rest was free

its highly unlikely you would have caused hot spots and burned the plants , if you were useing hid lighting then maybe , plus you said yourself you used the dull side

tin foil is very poor for reflectivness , moreso then youd imagine , flat white paint is a better option

peace

Nice. A dollar. And I just build the below gear for 5, hehe. Oh well. Thanks for the input dude. I would also need something to fit those dishes on, since it's for side light.

That's pretty groovy man, and surely a cheap way to do it. I would have thought metal to burn the ladies tho, but now I'm wiser. Thanks

I build two of these and spray painted them with flat white paint just a few hours ago.. You can hardly see the bulb in this photo.. But I figure you guys get the point..

They're fit with 45 degree angles, and made of wood, btw. Then painted flat white.

painting them is definitely a better idea. As to mylar, thay aren't the best option, but definitely a good one when the budget is tight, is space blankets. I got 4- 52"x82" space blankets off ebay for $4.88 shipped! can't beat that for a budget solution! But flaT white paint is also excellent.

Hey man.I saw this and just wanted o pass on a trick when I did a similar thing.Make sure your blankets are a handfull of inches longer than level with the floor.Find a nice Dowel or decent heavy wood and roll up the bottom of the Blanket and it keeps it more taught than ramming tacks n tape everywhere.easy on the walls and less work.LOL!hey less work and I felt it was more evenly smoothed out.Just an idea man,thought it might help ya out.Best of luck :smoke:

 

[Dr Cannabis]

Well, thanks for all the tips guys, much appreciated. I have now gotten the new flat white reflectors in level, so this is my setup now..
