TOTAL VENT FROM THE

for growers, by growers Born of the berry growing industry over 30 years ago, Haygrove now supply growing systems to the best growers of over 30 crops in more than 50 countries around the world. As commercial growers ourselves, Haygrove understand the complex challenges presented by climate, geography, crop sensitivities, labour resourcing, market demands and the ongoing development of technology that will reshape the horticultural industry. Haygrove’s engineers work with growers to innovate solutions that are functional, sustainable and profitable. Haygrove polytunnels, substrate systems...

total vent the Ultimate in venting flexibility Haygrove’s Total Vent polytunnels are uniquely designed to mechanically roll the polythene to the apex of the tunnel, creating precise climate control and mitigating the effects of extreme weather events. (Pending International Patent Application PCT/GB2022/050212) superior Tunnels for Optimum Return On Investment At Haygrove we develop commercial solutions for a huge range of customers, from small-scale growers to international horticultural specialists. Total Vent is part of our premium Advantage range, designed and used by us in our farms...

Being growers ourselves, Haygrove are always asking: how can we best anticpate the challenges of changing climates, complex and demanding markets, and a rapidly evolving industry? Total Vent’s innovative strength and function safeguards both the valuable crop and the tunnel structure investment from increasingly frequent extreme weather events. Total Vent allows growers to adapt quickly to the ever-changing challenges of horticulture. Growers can be versatile today, and over the 25 year lifespan of the Total Vent investment.

Total Vent is part of our premium Advantage series which has been specifically engineered with tomorrow in mind. Strength, ease of management and a superior agronomic environment allow growers to reduce labour requirements, extend cropping seasons, optimise yield and quality and adapt to changing conditions. Climate Control Total Vent allows for better temperature and humidity control, as the roof or sides of the tunnel can be opened in hot weather. The vents on Total Vent are in the most effective position to allow hot air to escape as it rises vertically. Ventilation Adequate ventilation...

A STRONG AND SMART DESIGN Innovations in Haygrove’s Advantage range reduce set-up and running costs, including for skinning and venting, climate control and picking. Intelligent, cost-effective automation reduces the labour requirement — mitigating the rising cost and scarcity of quality labour. Through combining versatile infrastructure with a reduced payroll to optimise tunnel management, profit can be maximised while preparing for a robotics-centric future. Total Vent is available in bay widths up to 10 metres wide. This is comparable to those of a glasshouse, rather than those of...

RAINWATER GUTTERS Water availability is becoming an increasing concern, therefore it is a valuable asset to be able to collect and store water for crop irrigation. The benefits of mechanised venting go beyond improving yield, quality, and season extension. The combination of Total Vent fitted with Haygrove’s rainwater gutters optimises rainwater collection. The harvested rainwater can be collected and stored for irrigation, mitigating the risk of crop failure due to drought. Total Vent allows for the the vents to be closed quickly when rain is forecasted which both protects the crop and...

SURVIVING THE SPIKES Protecting crops from pests and adverse weather, Haygrove’s Advantage range optimises climate conditions for specific environments and needs. Minimising wastage and maximising yield potential, Haygrove’s industry-leading growing systems also enable forecasting with greater accuracy, and therefore help to build strong relationships with customers who can rely on performance. Confidence in a consistent supply of quality products will lead to the access of premium markets and the opportunity to increase profit margins. A fundamental advantage to growing in Total Vent...

Enhanced Cooling and Temperature Control Proper VPD management contributes to effective cooling of plant surfaces through transpiration. The regulation of opening and closing the roof and sides of Total Vent promotes airflow and transpiration, preventing overheating. Reduced Stress and Improved Resilience Plants experiencing stress due to high VPD levels or inadequate moisture uptake can exhibit reduced growth and susceptibility to environmental stresses. Optimum VPD control promotes healthier and more resilient plants that can better withstand climate fluctuations. Optimal Photosynthesis...

Our Advantage tunnels have been specifically designed to maintain optimum climate conditions outside of traditional cropping seasons, increasing yield-potential in both volume and flexible planting. Investment costs are absorbed over a longer period, enabling you to price competitively within the market, and achieve a greater return on investment. Transpiration is a process by which water is absorbed by plant roots, transported through the plant, and then released into the atmosphere as water vapour through the stomata. Transpiration is a crucial physiological process that influences plant...

POllination Total Vent offers several advantages when it comes to pollination, which is a critical process for the reproduction of many plant species. Enhanced Crop Yield and Quality Effective pollination leads to increased fruit set, larger yields, and improved fruit quality. By ensuring a controlled and suitable pollination environment, Total Vent can contribute to better overall crop productivity. Pollinator Access Total Vent helps to control of the movement of pollinators such as bees and other insects. By opening the vents during periods of pollinator activity, access to the plants is...

natural light Total Vent has the ability to fully open and expose plants to natural sunlight when the weather is favourable, whilst still protecting the crop. This can enhance photosynthesis and overall plant health. When used in conjunction with Haygrove polythene and a retractable shade net, growers have a number of options to manage the light and climate variables to influence the crop. Daily Light Integral (DLI) is a measurement of the total amount of photosynthetically active light received by plants over a 24-hour period. DLI is a critical factor in plant growth and development, as it...
