SunFlex Beaver Shield Grow Tubes - 46-in Height Stops Beaver, Nutria & Other Smaller Critters From Killing Your Seedling Trees! 

It's no secret that beaver and nutria can decimate riparian tree plantings. Young seedling and sapling trees with tender bark are no match for powerful beaver and nutria teeth and jaws. Choose SunFlex to keep your seedling trees growing fast, straight and strong in the riparian zone where beaver and nutria live.

Deer Browse Alert: 4½ ft tall (and shorter) grow tubes, tree tubes and tree-shelters of any kind do not protect against deer browse above the height of the tube - period! If deer are in you area choose either the 71-inch Buck Shield™ or 58-inch Doe Shield™ SunFlex Grow Tube System.

Deer are unquestionably the number one threat to nearly all wild-land, and today, many urban tree plantings. When you're planting in "deer country" SunFlex is the only hope a young seedling has. White-tailed deer, with an average height of 36-40 inches at the shoulder plus its neck length, can easily browse nearly any unprotected tree below a height of about 52-inches (4.5ft) tall. That's why our "Deer Stopper" Grow Tubes start at 58-inches go up from there.

Trying to grow unprotected hardwood seedlings or those in a grow tubes (or tree-shelter or tree tube) below a 4.5ft height is usually futile. Unprotected seedlings stand no chance against hungry mouths - see image on right showing the all-too-familiar fate of an unprotected seedling. Even shorter tube shelters less than 4½ ft tall are of little use as they expose the emerging tree right at, or close to the feeding level for all North American deer. Once deer munch the top a tree's natural form is irreparably harmed. The tree usually responds by robbing its root system to replace lost growth in an often futile effort to grow past the deer. And if deer don't get your young seedlings, there's a good chance that the rabbits will.

The before and after images below show how easy it is for deer to browse seedlings that emerge from the top of shorter tubes (35-in tube shown below). The lesson here is don't waste money trying to save money on tubes too short for the animal threat in your area. Instead, choose a grow tube tall enough to get the job done right the first time you plant. Choose the SunFlex Doe Shield (58 inches tall) or SunFlex Buck Shield (71 inches tall) to get your trees growing safely above the browse-line!

Superior plant growth is packed in every SunFlex "Greenhouse Grow Tube" engineered to optimize the Big 4 - SunlightCO2, Moisture & Temperature

  • SunFlex is designed for a wide range sunlight conditions which receive a minimum of 6 hours of uninterrupted sunlight per day duringthe growing season.
  • Unlike traditional tree tubes and tree shelters SunFlex Greenhouse Grow Tubes are twin-walled for light diffusion and translucent to growth-optimizing sunlight trees and shrubs need. SunFlex is packed with advanced greenhouse technology to stimulate phytochrome to grow the whole plant from roots to shoots necessary to get your new seedlings off and running with the sun.
  • In addition to providing superior greenhouse benefits the entire SunFlex series is engineered with Plantra's Cross-Flow™ venting. Cross-Flow promotes effective air movement to increase CO2 replenishment, reduce excessive moisture buildup and encourages proper dormancy (hardening off) before winter, even in the coldest regions.

Rigid, twin-walled construction protects against the wind, wildlife & weeds that can kill young seedlings:

  • SunFlex Grow Tubes provide a physical barrier to shelter seedlings against chewing and browsing wildlife that can destroy a entire planting season in a few bites. The 58-in tall SunFlex Doe Shield and 71-in tall SunFlex Buck Shield grow tubes provide the most effective browse and trunk protection against damage from small rodents to animals as large as deer. 
  • Wind is a seedling killer and while wildlife gets it fair share of the blame for damage to new plantings, wind's invisible force rarely does. Built rugged and sturdy, SunFlex creates a greenhouse micro-climate that blocks wind which can dry out tender leaves. This reduces water stress on the leaves, stems and roots and allows the plant to channel its energy into faster, sustained growth instead of defending itself against desiccating winds.
  • SunFlex helps you control weeds that steal soil nutrients, moisture, and sunlight from young seedlings by making it easy to see exactly where your seedlings are when using mowers and string trimmers. The solid lower section acts as a spray shield for weed sprays making weed control fast and safe (always follow chemical label directions when applying weed sprays).

Ready for the Field:

  • SunFlex ships flat, pops open to a large, leaf expanding 3.9 inch diameter, and installs quickly and easily with super-strong, releasable Plantra Twist-Lock™ double-wire ties (included).
  • Large tie holes come standard on all Sun Flex Grow Tubes to accommodate the widest range of staking options. The most secure method is the SunFlex Grow Tube System which incorporates our Trunk-Builder fiberglass stake into the strongest stake and tube attachment system available.
