How Much Lighting Is Used Growing Tomatoes In Commercial Polytunnel? More Discovered!

Gardeners in the UK must know how much lighting is used growing tomatoes in a commercial polytunnel, which is 60 Watts/m2 for 16 to 18 hours per day. Regardless if you’re growing in the polytunnel for business or personal use, it’s crucial to generate the optimal conditions indoors for your plants to thrive. A common mistake is to focus on the ideal temperature for growing tomatoes only and then neglect the lighting.

Much like temperature, the lighting system in the polytunnel plays a significant role in the success of your tomato garden in the UK. Plants won’t be able to perform photosynthesis if the conditions indoors are incomplete. Tomatoes thrive in full sun, but because we don’t want to overheat the polytunnel, supplemental lighting is the best solution to provide their lighting requirements.

What You Need To Know On How Much Lighting Is Used Growing Tomatoes In Commercial Polytunnel

In general, the amount of lighting that tomatoes require in a commercial polytunnel is 60 Watts/m2 for 16 to 18 hours per day. UK experts recommend this amount both for sowing and transplanting by the government of Alberta. Since you’ll be running a commercial tomato polytunnel, it’s crucial to plan the lighting system and how to achieve this requirement. 



In the seedling nursery, high-pressure sodium lights will provide this condition. However, the placement of the lights is also prominent. Have the lights 6 feet above the seedlings and a distance of 9 feet between each light. Each row of light will then have 12 feet of space between them. 



Once you see the first real leaves appear, you will have to transplant the seedlings. The amount of lighting is still the same, but Alberta also recommends adding carbon dioxide supplementation. According to their findings, this combination will improve early yields. 

You will eventually have to reduce the lighting duration to 12 hours a week before beginning the second transplanting. This way, you can condition the transplants to the main polytunnel changes and avoid light shock. Otherwise, their development will halt. 


How Lighting Affects Tomatoes In Commercial Polytunnel

Now that you know the amount of lighting for the growth of tomatoes, you must learn what makes lighting crucial in a commercial polytunnel. For starters, the colour of growing lights affects plants’ growth because they will dictate the similarity with the spectrum your plants use. Additionally, we all know that maximum light intensity will create the best fruit set.

The maximum light intensity is the exact reason why you’ll notice a higher yield in the spring compared to autumn. Additionally, failure to provide the optimal lighting conditions will even prevent the tomato plants from developing flowers. Instead, they will only produce leaves and stems until there is light to support the flower and fruit. 

You must also be consistent in providing the optimal conditions throughout the growing season. For example, if the plants experience a sudden limitation, they risk getting smaller fruits. Smaller fruits will reduce the yield and even the quality of your harvest. 

What Is The Best Light For Growing Tomatoes In Commercial Polytunnel?

For growing tomatoes in a commercial polytunnel, you must know which type of light would be the best choice. High-pressure sodium lights are an economical choice in a commercial polytunnel. Cornell University also mentioned that they are great for increasing light intensity and extending day length. 

However, you must always check the setup of high-pressure sodium lights so that you’ll get uniform lighting in the entire polytunnel. But what about LED lights? Are LED lights the right choice for commercial polytunnel tomato production?

LED lights help in increasing the fruit number and yield. More so, using them in comparison to other supplemental lighting shows an increase in energy savings. Over time, you will have lesser expenses and higher profits.


Is Growing Tomatoes A Good Business?

Growing tomatoes is a good business because of the rapid growth of the industry. Using a polytunnel for production is a good strategy. The polytunnel is efficient because you will always be able to provide tomatoes at an excellent price, especially when they are out of season. 

You won’t need to worry about unpredictable weather and diseases. Using a polytunnel will ensure a steady production volume, and while you’ll also need to allocate a budget being indoors, you can always learn about economic strategies. As mentioned by the Mississippi State University Extension Service, the success of a commercial polytunnel tomato production will depend on your management skills. 

Proactiveness and consistent attention are vital characteristics that you must possess. 



As previously discussed, growing tomatoes in a commercial polytunnel is an excellent investment to venture into. However, you must know the proper management practices, including how much lighting is used growing tomatoes in a commercial polytunnel. The recommendation is 60 Watts/m2 for 16 to 18 hours per day for sowing and transplanting. 

Ensuring the proper lighting in the polytunnel has a considerable impact on the production and yield of your crops. For the type of lighting system to use, extensions discussed the advantages and disadvantages of LED lights and high-pressure sodium lights. Choosing between the two will depend on which you think is more beneficial for your situation. 

Overall, the lighting system is a part of a polytunnel that UK gardeners must never neglect. Regardless of the crop you have, you must meet their requirements to ensure a productive polytunnel.

How Should A Mattress Fit On A Bed Frame? 4 Questions Asked!

Are you wondering how should a mattress fit on a bed frame? When you are buying a mattress, the size should be in consideration.

This question is quite broad to answer which you want to know the answer.
