I used general purpose spray adhesive for the mylar, but it really didn't hold all *that* well. I help it with silver duct tape on the corners. I just bought some panda film and it seems a good bit heavier - I'm not confident in the spray adhesive and don't want the stuff to fall on my HPS. Thoughts? Here's a link to my grow journal: http://forum.grasscity.com/indoor-grow-journals/313839-my-first-grow-attempt-post3604021.html
yeh mate heavy duty staple gun is pretty much the answer to your question but you need to cut 2" x 2" pieces of thin card board and drive your staples through it so the weight of the film doesn't pull the staple through , adhesive spray just gives you worries
Hmm - interesting idea. I might combine that with the spray adhesive. I like the spray because it prevents the mylar film from flapping around at all. It stays perfectly still.
this is how i built my second box. framed out of wood. cut up a cereal box and staple gun it all up....still holding up.....using the cardboard evens out the tension more evenly..3 or 5staples in each piece of cardboard is enough to secure..
yea, there is also that 3m double adhesive tape, works nice. I never liked the spaples cause ure blocking the reflective p-art where u staple a 2x2 inch CB to it.
