Without adequate light, they simply will not yield flowers or fruit. That’s why successful indoor gardeners use grow lights.
Can I start tomato seeds without grow light?
The goal is direct sun. Indoor seed starting has its place and I use it every year. But you may not have the time, resources or space to set up a grow-light station. You can simply plant a flat of tomatoes or other plants and put them out during the day and bring them in at night.
Can you grow tomatoes entirely indoors?
Find the Perfect Place: Tomatoes won’t effectively grow indoors unless the conditions are like those of an outdoor garden. The plants need a good eight hours of sunlight per day and a surrounding temperature of around 70 degrees Fahrenheit or higher. Consider a spot on a window sill or near a screen door.
Can you grow seeds indoors without grow lights?
That being said, you don’t absolutely need indoor seed starting lights if you have a sunny windowsill, porch, or another space filled with natural sunlight. I’ve started lots of different types of seedlings in my sunny spare bedroom, and they survived just fine (though they were always a little leggy).
How many hours of light do tomatoes need indoors?
eight hours
Tomatoes need full sun and at least eight hours of light to produce any fruit. Temperatures should be in the range of 65 F. (18 C.) or more indoors. Use unglazed pots that will breathe, with good drainage holes when growing indoor tomatoes.
Can seeds germinate without light?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007).
Can you start seeds without light?
Alternately, if it is warm and sunny enough, seeds can be sown directly in a thin layer on the soil. A greenhouse in direct sunlight in early spring can also provide enough light and heat for germination. Seeds that don’t need light to germinate should be sown in trays.
How long will a tomato plant produce indoors?
A tomato plant started indoors can continue to bear fruit all year long because it’s not at risk of freezing. You just need to be diligent about taking care of it. “The best bet is to try a few different varieties and plant some seeds every two to three months,” LeHoullier says.
How long can a tomato plant live indoors?
A tomato plant typically lives for one growing season (6-8 months) when grown outdoors, but when nurtured in ideal or controlled growing conditions indoors, tomato plants can survive between 2-5 years. Propagating healthy cuttings may also extend its life indefinitely.
How often do you water indoor tomatoes?
Tomato plants need to be watered daily or every other day unless you have had recent rain. The plants need 1-1.5 inches of water per week, but container-grown tomato plants need to be watered twice per day. The best time to water your plants is early in the morning before the sun gets too hot.
Can you grow vegetables indoors without grow lights?
All you need is a sunny, south-facing window and a few basic supplies to get started. I’ll show you what I like to use, along with 10 easy crops that can be grown successfully indoors without grow lights, shop lights, or other artificial lighting.
How many hours of light do seeds need to germinate?
16-18 hours
A sprouted seed is no longer a seed but a seedling, a miniature plant. The most important thing to consider and deliver is adequate plant light. Seedlings need more light than full grown plants, ideally as much as 16-18 hours a day.
What is the easiest seed to grow indoors?

Does artificial light help tomatoes?
Tomatoes (Solanum lycopersicum) need at least eight hours of direct sunlight per day, but that’s not always possible when you’re growing the plants indoors. The plants respond well to artificial light, as long as you meet their color requirements and time needs.
Can you grow tomatoes in the dark?
Lighting Needs for Growing Tomatoes
Tomatoes needs at least 8 hours a day of sunlight to produce fruit, but aim to provide 12 -16 hours of light for the best growing results. Tomato plants are day-neutral, meaning that they will flower independently of the day length.
Is it OK to leave a grow light on all the time?
A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
Will seeds grow in a dark cupboard?
Thus a seed will germinate in the dark, as it does not need a source of light in order to start growing. The bean plant in the dark cupboard grows tall because it is seeking light (phototropism) – but as there is none, it is not stimulated to produce the green pigment chlorophyll, and so cannot photosynthesise.
Can vegetable seeds germinate in the dark?
Most seeds germinate best when they’re placed in the dark. The presence of light, which is crucial to seedling development, may actually stunt the process of germination.
Why do seeds don’t need light to germinate?
This is especially true for seeds that do not germinate in the dark such as lettuce, cabbage, and dill. Some types of seeds do well without exposure to light. These seeds need less energy for their growth process because they grow roots downward instead of seeking out more light like most plants do when growing upward.
Which seeds do not need light to germinate?
Some other popular types which prefer darkness for germination are:
- Calendula.
- Centaurea.
- Delphinium.
- Gazania.
- Nemesia.
- Primula sinensis.
- Schizanthus.
