    Grow Strong Plants, Faster:

    In a side-by study our greenhouse covers have proven more effective in growing plants and vegetables than the competition. Our 5.5 oz., rip-stop polyethylene cover is made strong and reliably retains heat to create the ideal environment for plants and seedlings to flourish. In a study we found that plants grown in a greenhouse utilizing our unique cover required less water than those grown in competing greenhouse units.
