Fluorescent lights are ideal for plants with low to medium light requirements, like African violets. They are also good for starting vegetables indoors. ... In addition to this, fluorescent bulbs use 75 percent less energy than incandescent lights.

Are fluorescent lights the same as grow lights?

The right kind of grow lights can make all the difference in how your plants perform. ... Standard indoor lights do little to influence photosynthesis, while using fluorescent lighting placed closely to the top of the plants can help drive this important plant process.

Is LED or fluorescent better for plants?

When it comes to energy efficiency, LED grow lights beat out the best fluorescent grow lights, hands down. When comparing lighting efficiency, it's important to look at the light levels delivered to plants rather than just the electrical watts.

Do fluorescent lights hurt plants?

Plants and Fluorescent Light

Plants growing under fluorescent lights can thrive and exhibit good foliage, but blooms may be delayed or never appear at all. Too much fluorescent light will also harm plants -- artificial light should mimic the day and night cycles found in nature.

Can plants grow in just artificial light?

Researchers can successfully grow plants using only artificial light in growth chambers. But sunlight is best for most plants. It's generally more intense than artificial light, and it's pretty equally distributed among the different wavelengths that earthly plants have evolved to like best.

Can plants survive with LED light?

Offering low energy usage, low heat, and color optimized for growth, LED lights are the most efficient, effective, and customer-friendly way to grow plants at home than growing with fluorescent lights or incandescent lights.

How far should fluorescent lights be from plants?

Fluorescent tubes give off little heat, so can be placed as close as four to six inches above seedlings and plants. Incandescent and similar bulbs give off more heat, so need to be kept a foot or more above plants.

Do fluorescent bulbs give off UV for plants?

Incandescent and fluorescent bulbs both emit UV radiation, but the levels are low when compared to reptile basking bulbs or tanning bulbs. The strongest source of UV radiation is the sun.

Can I use a shop light as a grow light?

What is an inexpensive alternative to expensive standard grow lights? Seedlings can be effectively grown with inexpensive shop lights as long as you purchase the right bulbs. Use a bulb with a Kelvin rating of 5,000 to 6,500, and an output of at least 2,500 lumens.

What is the difference between a shop light and a grow light?

Answer: Yes. There is a big difference between regular shop lights and grow lights. Grow light bulbs cover a fuller light spectrum closer to that of sunlight. ... Some fluorescent bulbs are specially designed for plant growing and cover more of the spectrum–up to 94%.

What is the difference between a grow light and regular lights?

Grow lights have a shorter lifespan than regular LEDs. The intensity of grow lights makes them more likely to burn out at a faster rate than regular light bulbs. ... That way, you will be able to create the right environment that promotes growth by choosing the right lights that help your plants flourish.

Can I leave my grow light on 24 hours?

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.

Can I use T8 bulbs to grow plants?

Tip. Four T8 fluorescent light bulbs will work well for growing vegetables indoors as long as you leave them on long enough to give the plants enough light.

Is UV and fluorescent light the same?

As mentioned above, fluorescent tubes use the same technology to create ultraviolet radiation as the UVC bulbs, but they use different phosphors to convert that UV radiation to visible light. The phosphors absorb the UV, making them safe, and emit visible light.

What UV light is best for plants?

When it comes to the full UV light spectrum, it's best to stick with UV-A and UV-B varieties for your plants. As mentioned, there is no benefit of direct UV-C exposure to yourself or to your crop (although UV-C may help sterilize your grow room).

How far away should a grow light be from tomatoes?

Tomato seedlings need high intensity light. Fluorescent bulbs should be placed very close to the plants, no more than three inches away from the soil surface (before seedlings emerge) or foliage (once seedlings sprout.)

How many t5 lights do I need for veg?

long and have 1, 2, 4, 6, 8 or 12 bulbs per fixture. If you are thinking of growing only a few small plants, you might get away with having a 1- or 2-bulb set-up that is 2- or 4-ft. long, but if you want to grow a whole bunch of plants, you will have to invest in an 8- or 12-bulb set-up that is 4-ft.

How many watts veg stage?

Veg Room Set Up

A good rule of thumb is that between 10-20% of your total light wattage in the Flower Room will be used in vegetative growth. This means that if there are 50,000 watts in the Flower Room, there should be between 5,000 and 10,000 watts in the Veg Room.

Why should we not touch plants at night?

While many plants release carbon dioxide, not oxygen, at night, having a few plants in the bedroom will not release enough carbon dioxide to be harmful at all. Also, not all plants release carbon dioxide at night. Some still release oxygen even when they are not in the process of photosynthesis.

What color LED light is best for plants?

We could say that the two most important light colors to place in an LED lamp are: red and blue. Red is the main component that plants need for photosynthesis and stem elongation inhibition. Additionally, it signals to the plants that there are no other plants above it and that it can thus have uninhibited development.

Are white LED lights good for plants?

When combined with the 20%-40% efficiency loss, "full spectrum" white LEDs are less than half as efficient for growing plants than the correct mix of pure-color LEDs-- white LED grow lights force you to cool your growing environment more, just like HPS and MH, losing a lot of the other advantages LEDs offer.

Can regular fluorescent lights be used to grow?

The short answer is: any type of fluorescent light will help any type of plant grow, whether it is cannabis or lettuce or orchids. ... While you can use any type of tube or bulb and see results, you want to provide the kind of light your plants want most.

Is T5 or T8 better for bearded dragons?

In my opinion, the T5 is vastly superior – it has a much higher UVB output and can be placed 12″ to 18″ away from your bearded dragon. ... T8 bulbs, on the other hand, should be placed within 8″ of your Bearded Dragon. Since UVB output is much lower in T8 fixtures, the bulb must be placed inside of the tank.

Can you use T8 for clones?

For use in cloning, seeding, and rooting: Choose the T8s

If you were to use a brighter, hotter T5, you would run the risk of scorching the plants or upsetting their biological rhythm necessary for the early stages of growth.

Should lights be on during germination?

First, true enough, light isn't necessary to germinate most seeds: the majority are perfectly capable of germinating in complete darkness. But there is a significant proportion of seeds that will not germinate if they aren't exposed to light. This includes maybe a third of the plants we commonly grow from seed.
