Covering Low Tunnel

whoose · May 12, 2018

I have been using 6mil clear plastic (Visqueen) for my covers on my low tunnel beds. Problem is that it last only one season and makes a mess as it comes apart. Better suggestions/sources are welcomed.

you need to use uv resistant greenhouse plastic. it lasts for years.

I've been using this for the last seven years and it is still going strong in Mississippi. Claud

Tip: You want the film to be tight enough it doesn't flap in wind. Movement will cause it to fail prematurely.

AND... this year we had a "funny" issue occur...my one house quit inflating but the fan was running and I searched all over the outside of the house for a hole... I could not find anything that would account for the loss of air. BUT where the plastic electrical conduit was up against the plastic must have had a chemical reaction to the greenhouse plastic.. it literally disintegrated along the the spots where they touched each other. so, whatever you are stretching it over... watch for deterioration... just a heads up!

Ordered some of the fancy covering today. What kind of tape do I need to keep it from touching the plastic?

The same site that sells the covering also sells rolls of heavy repair tape that works great. I use the rigid foam pipe insulation (cut into 1 foot pieces) on the frame to act as a hold-off for the plastic. Claud

I used regular greenhouse repair tape for my patching. it was way cheaper than replacing the plastic. since yours is brand new I would suggest taping the plastic pipe with the tape instead of trying to guess where the plastic will touch it.

I used latex paint on my PVC pipe. It seemed to work OK.

Any updates? I'm probably going to replace my floating row cover with some of the plastic stuff. Here's a picture of my make-shift medium tunnel.

I can get the uv resistant (4-5 year) plastic for 15 cents a square foot, cut to my specs. Is this a good price?

I think it is, provided it is new stuff. Some greenhouse operations sell their used plastic.
