Greenhouse shading has been around as long as…well, greenhouses. Whether it’s emulsion paint, cloth or even those fancy roll-able wooden ones, the idea is the same. On a hot day, greenhouse temperatures can soar to well over 30°C and if we don’t keep plants cool by blocking out the sun, they’ll die. Right?
It is partly right. Hot weather is a common threat to gardeners and one that keeps us constantly vigilant. We must make sure plants are well watered, our greenhouses & poly-tunnels are well ventilated and the temperature is monitored at all times. But is blocking the sun out really the right option?
By blocking out the sun we are reducing the effect of photosynthesis. Plants depend on light to grow, so the more light we block out, the less they will grow. What if we had a spell of hot weather that lasted weeks? Okay, it’s not very likely, but the only option would be to starve the plants of sunlight until the weather cooled down again.
Then you have the added stress of getting to your greenhouse every sunny morning and opening the vents, applying the shading etc. Not to mention the risk of breaking a pane of glass in the process.
We’ve got a simpler option that not only protects your plants but has been proven to increase growth and yield in tests done at The University of Nottingham.
Envii Chill Out removes the need for shading or painting greenhouses. It’s a bio-stimulant designed to allow plants to survive and thrive in temperatures above 30°C. It’s made up of plant extracts that work together to manage a plant’s reaction to heat stress. The plant’s natural reaction of aborting buds, flowers and shoots is changed to direct the plant into growing larger roots and focus on getting more nutrients and water from the soil.
Then, when the temperatures drop, the plant continues to grow aerially but with the benefit of larger root system to get more nutrients and therefore improve growth and yield.
This means that by treating your greenhouse plants with Chill Out, you can grow with confidence even when the sun is out. The product has been extensively tested in Middle Eastern glasshouses where the temperature can rise above 40°C.
Think of it as an all-round plant treatment for greenhouses or poly-tunnels that will save you time, effort and most importantly make sure your plants will continue to grow all summer long.
