If you’ve ever tried a supermarket tomato and then a homegrown tomato, you’ll know there is no comparison. A vine-ripened tomato is a far superior product to the bland, tasteless, and mealy tomatoes found in supermarkets. There are many other reasons to plant tomatoes.

Tomatoes can be finicky plants. Even if they have a long growing season, getting them to ripen evenly may not be possible. You can manage the sun and water they receive so each fruit is perfect and juicy. Also, homegrown tomatoes tend to be thinner in the skin, which makes them less susceptible to splitting or cracking.

Although store-bought tomatoes can be purchased annually, nothing beats the taste of a fresh-picked tomato warm from the vine. Growing tomatoes at home is an excellent way to ensure fresh ingredients.

Growing Tomatoes in a Greenhouse

Growing tomatoes in greenhouses have many benefits. You can make a lot of money if you grow tomatoes commercially. It is essential to select the right cultivar for your growing area.

Many tomato growers want the plant that produces the most fruits per tomato. This will allow you to balance the costs of growing tomatoes and the profits they bring. Growers may also be aware of the market demand for particular varieties of tomatoes. Some growers are more concerned about ensuring that their plants are resistant to disease.

Growing tomato seedlings

A greenhouse is the best place to begin your tomato garden. A greenhouse will give your plants a steady supply of water and nutrients. The humidity will also be kept below 90% to prevent leaf mold. A soilless tray with a nutrient solution is best for tomato seedlings. The RSI Hydroponic Floating Seeding Trays are known for their high success rates.

You should start your seeds six weeks before the last frost date. Then, plant them one week to ten days later. This will prevent any surprise frosts and allow the soil to warm up before transplanting your seedlings. The best time to sow seeds in the US is March and April. A greenhouse-growing guide contains specific information and tips for seedling growth.

Growing Tomato Plants In Plug Trays

You can grow tomatoes in a plug-tray greenhouse by either starting your seedlings indoors in an indoor germination greenhouse or transplanting them to a permanent place. Before transplanting tomato plants to a permanent location, they must be hardened for at least a week.

Simply take your plant out of the greenhouse and put it in partial shade for at least a few days. You can then transplant your plant to full sun and water it.

When germination occurs, the soil in the plug tray greenhouse must be moist. A coconut coir can be placed between the earth and the tray to prevent overwatering. Watering is essential in the later stages of development.

The soil mustn’t be too dry. To prevent plants from dying, it is important to water them properly after transplanting. You must water your plants daily to achieve the best results.

Growing Tomato Plants under Supplemental Lighting

The lighting conditions in greenhouses for tomatoes are often not ideal. Supplemental lighting is vital for growing tomatoes any time of the year. However, it can be costly and have a large ecological footprint. Generally, high-pressure sodium (HPS) lamps provide additional lighting.

HPS lamps emit warm light, which benefits many plant species. LED lamps emit narrow band light which consumes less energy.

Grow lights should provide 14-16 hours of light per day for tomato seedlings. To grow tomatoes properly, they need more light and should be grown under grow lights instead of direct sunlight.

You may need to shade your tomato plants depending on where you have them. Reduced photosynthesis can also lead to lower yields. Shade cloths can stain individual fruit trusses.

Pollinating Tomato Plants

Pollinating tomatoes in a greenhouse is a crucial step. Although tomatoes can self-pollinate, they do require some help. Bumble bees and wind can help you with pollination. If this isn’t possible, you can also use plant vibrators or electric toothbrushes.

Fans can be used to direct the airflow in the greenhouse. You can also use cotton swabs or hand pollination to move pollen from the stigma to the anthers. Hand pollination should only be performed every other day for best results.

Tomatoes, unlike other fruits, cannot self-pollinate in greenhouses. Pollen is held in flower capsules and must be removed manually. Buzz pollination is the name of this process. Honeybees can do buzz pollination, but they are not suitable for commercial honeybees. You can instead try the Australian blue-banded or European bumblebee, which can buzz pollinate.


Grow tomatoes in greenhouses. They are very popular. It is essential to learn about the growing process so that you can grow tomatoes with success. To grow well in greenhouse tomatoes, you need to provide adequate lighting, water, and pollination.

Growing Tomatoes in a Greenhouse FAQ

What is the best way to start tomato plants in a greenhouse?

You can either start your seedlings indoors in a germination greenhouse or transplant them to a permanent location. When transplanting tomato plants into a permanent place, they should be hardened for a week or two before planting.

What are the lighting requirements for tomatoes in a greenhouse?

For best results, you should use grow lights that provide fourteen to sixteen hours of supplemental light daily. Tomatoes need additional light to grow properly and are best grown under grow lights rather than direct sunlight.

How often should I pollinate my tomato plants?

For best results, hand pollination should be done every day or every other day. Unlike many other fruits, tomatoes cannot self-pollinate in a greenhouse. Pollen is trapped in capsules in flowers and must be released by hand.

My tomato plants are not producing fruit. What could be the problem?

If your tomato plants are not producing fruit, it could be due to a lack of pollination, too much shade, or inadequate lighting. Ensure you provide fourteen to sixteen hours of supplemental light daily and that your plants are getting enough pollination. You may also need to reduce the amount of shade if your plants are not receiving enough light.
