Tomatoes are a popular crop to grow indoors, and the amount of light they receive is an important factor in their success. In this blog post, we'll discuss the optimal lighting schedule for tomato plants, based on advice from experienced growers.

One method that has been successful for some is 12 hours of light followed by 12 hours of darkness. This works well with people's schedules since it allows 8 hours of sleep during the dark period. It also mimics natural daylight cycles and helps reduce stress on the plants.

Another popular method is 10 hours of light followed by 14 hours of darkness. This gives the plants more time to rest and store energy, which can be especially beneficial during winter months when ambient temperatures and humidity are lower. Additionally, when potting up tomato plants, it's important to consider the size of the growing pot relative to the root network - too large a pot could encourage full growth mode prematurely.

Finally, Mike mentioned having good luck with 12/12 lighting but noted that it isn't necessarily a magic number. He suggests aiming for 100 watts of light per square foot, which would help prevent stretching due to insufficient light. To put this into perspective, maximum daylight in Mexico City is 13 hours 18 minutes on the longest day, while at the equator it averages 12 hours all year long.

In conclusion, there is no one-size-fits-all answer when it comes to lighting schedules for tomato plants indoors. Experimenting with different methods may yield better results for your particular situation, as ambient temperatures and humidity levels can vary significantly throughout the year. Ultimately, monitoring light to darkness ratios carefully will ensure your tomatoes get enough rest and energy storage for healthy growth.

What is the recommended lighting schedule for tomato plants?

I have seen good results with a 12 hours on, 12 hours off lighting schedule. This allows the plants to get some dark time as well as fit into people's routines.

What is the importance of dark time for tomato plants?

Dark time is important for completing the cycle of photosynthesis.

How much light do tomato plants need?

Tomato plants need about 100 watts of light per square foot in order to prevent stretching.

How much daylight does a tomato plant need?

The amount of daylight needed depends on where the plant originated from. For example, in Mexico City, the longest day has 13 hours and 18 minutes of daylight, while at the equator, there is an average of 12 hours of daylight all year long.

What type of light is best for tomato plants?

Tomato plants prefer full spectrum lighting, such as LED or fluorescent lights. This type of light provides the most balanced and natural spectrum of light for the plant.

How close should the light be to the tomato plant?

The light should be placed about 8-12 inches away from the top of the plant. Any closer and you risk burning the leaves, any further and the plant won't get enough light.

How long should I leave the lights on each day?

Generally, it's recommended to keep the lights on for 12 hours a day. This allows the plant to get enough light while also getting some dark time.

Is there anything else I should know about lighting my tomato plants?

Yes, make sure to adjust your lighting schedule according to the season. During winter months, when there is less daylight, you may need to increase the amount of time your lights are on in order to provide enough light for your plants.
