Two years ago I bought my first roll of Tufflite IV greenhouse film and have since used it in a variety of ways around the Runamuk farm and homestead. As I’ve progressed along my journey towards a sustainable life I’ve looked for ways to extend my growing season, ways to improve upon the things I am already doing, and methods for stacking systems on my farm. The Tufflite plastic has served as a multipurpose and rugged piece of equipment that has allowed me to do just that.
For years I used the clear 4mil or 6mil contractor’s plastic so widely available at local hardware and garden centers. I learned the hard way the limits of that type of plastic when I used it to cover my first-attempt at a small hoop-house during the winter of 2013-14. The plastic became brittle and one careless swipe with the shovel was all it took to shatter the covering; I was picking up bits of plastic by hand come spring. Not fun.

What is Tufflite IV?
A broad range of farmers and gardeners are using this plastic on their greenhouses and in the construction of their high-tunnels. It provides protection for crops and seedlings from rain, wind, and frost, enables them to extend their growing season and allows for improved production of heat-loving crops in northern climates.
- 6mil plastic is heavy duty and durable.
- Light transmission is comparable to glass
- Won’t discolor over time
- Lasts a minimum of 4 years
- Protects crops/seedlings from increment weather
- Allows for season extension
- Expensive stuff!
- Used with PVC voids warranty.*
- Not a tarp! It can rip if not used correctly.
- Hard to find very small pieces.**
My experience with Tufflite
The Tufflite was a bit of an investment for Runamuk, but when used properly it lasts for years and it’s versatile enough that I’ve been able to use it in a wide variety of applications: mini hoop-houses, cold-frames, my new hoop-coop, and even the windows of the barn at our former location in Starks. I’ve also seen it in action on the high-tunnels of friends and at the Johnny’s research farm; it’s always a marvelous experience to step inside a high-tunnel to see the variety of crops that can be grown in those conditions.
*Johnny’s actually doesn’t recommend or even warranty this greenhouse film for use with PVC because they’re not sure how the polyethylene that the plastic is made from will react with the polyvinyl chloride that the PVC piping is made of. That being said, I have been using this plastic on PVC for the last 2 years and have had good luck with it.
**You can find the Tufflite film available from greenhouse supply companies including Johnny’s Selected Seeds. It comes in a range of sizes, though if you’re a home gardener with a small plot you may be disappointed that it’s difficult to find a very small piece. And forget getting a piece of scrap material─typically if there’s anything left over employees are quick to snatch that stuff up. My best recommendation if you’re looking for a small section is to go in on a roll with other gardening friends, or invest in the smallest roll you can get and then look for alternative uses for the plastic as I have done.
Tufflite does degrade over time and at some point it’s no longer suitable for seedling or crop production. However, often when farmers replace the film on their high-tunnels or greenhouses there’s still a lot of life left in the plastic. If you’re intending to use the greenhouse film for a project other than growing crops (such as on a chicken coop) you may be able to score a second-hand piece if you are friendly with local farmers.
Two thumbs up!
The Tufflite IV greenhouse film has opened up a number of opportunities for my farm: from production of seedlings and season extension in my garden, to portable livestock shelters that allow me to rotate my chickens on pasture. It may cost more, but the Tufflite is superior to the contractor’s plastic and has proven it’s worth here at Runamuk. I would highly recommend this plastic to anyone who is looking to extend their growing season or who is looking to create systems on their homestead or farm that allow for stackable functions. I give the Tufflite an emphatic two thumbs up!
