I have a 10’X10’kennel that I want to use as a greenhouse this spring. I also have a roll of 3mil plastic sheeting._(_ IDEA\*)\*. I have to somehow build a top for this brilliantly (ahm) ;)thought up structure;). What can I use to glue the plastic sheet together to form the gable ends And reinforce the corners and edges? The box doesn’t identify the type of plastic so I guess it is poly ethylene. ---

Epoxy glue generally works for that sort of thing. ---

Horticultural supplies salesman checking in here. You can’t glue polyethylene. You could use a tape-like product called PolyPatch for reinforcement. Most greenhouses use aluminum extrusion clamping rails to hold the poly in place. A popular version is called Uni-Lock. Most kennels have flat roofs. How were you planning to shed rainwater? Another issue is ventilation. Greenhouses can get over 100 F very quickly even on a cold day. Gotta vent somehow. 3 mil poly is a little light. Most greenhouses use 6 mil. I won’t advertize here, but feel free to send me an email. [johnburt@NOSPAMfast.net](mailto:johnburt@NOSPAMfast.net) Take out the “NOSPAM” bit.
