Lighting Time Required for Indoor Cannabis Cultivation
Make a donation. Once the preserve of professional growers, lighting systems can now be used to good effect in the home and greenhouse to grow plants. They can be inexpensive and do not need an in-depth understanding of the science and mechanics, so anyone wishing to experiment with growing plants under artificial lighting can have a go.
Many plants grow well in a bright location in the home. However, the use of artificial light can be of further benefit in the following circumstances;. Domestic light bulbs are unsuitable for growing plants as the light intensity is not enough and they are less energy efficient. For these reasons alone, it is best to choose specialised horticultural lighting.
Readily available from horticultural suppliers, T5 HO fluorescent tubes have the following advantages that make them the current top choice:. They benefit from low operating temperatures and are longer lasting and more energy efficient than T5 HO fluorescents.
At this point in their development, however, they can still be more expensive than T5 HO fluorescents to install. Specialist light meters may also be required to measure the light output of these systems, which can add to the expense of the set up.
HID High Intensity Discharge lights, which include metal halide and high-pressure sodium systems, give off a tremendous amount of heat. This makes them less useful in the home as extraction equipment is necessary to remove the hot air.
The bulbs cannot be placed close to the plants because of the potential damage from the heat generated, meaning more growing space is required. Plants absorb mostly blue and red light think of the colours present in a rainbow, plants use two particularly in order to grow and flower.
Blue light generally stimulates growth, while red light is important for growth and flower production. T5 HO tubes are available that produce colour values based on the Kelvin scale K. Tubes with a K value tend to produce light with a reddish tone, while those with a value of K produce bluish light. If using fluorescent tubes to grow flowering plants, a combination of red and blue tubes will provide the best light for growth and flowering.
There are a variety of kits available which include an electronic ballast that starts up the tubes and reflectors to direct the light downwards onto the plants. These benefit from predominantly blue light to promote good growth and compact plants. The T5 HO tubes should be placed around 60cm 2ft above the seedlings for around 16 hours a day. Tomatoes for example can be started earlier in the year under lights when natural daylight is still too weak.
This enables plants to be more advanced by the time they are planted in their final positions in the greenhouse or border. Again adjustments can be made regarding light intensity requirements. See: 'Problems' below. Phalaenopsis moth orchids and African violets Streptocarpus syn Saintpaulia can be grown under lighting very successfully and are tolerant of a variety of lighting conditions. Leaves should be a mid-green. Plants from naturally low-light habitats, such as ferns and many of the smaller tropical foliage houseplants that in nature inhabit shady forest floors, can be kept healthy long-term under simple artificial lighting.
Use an aquarium tank as a terrarium for these plants and position the T5 HO lights in the hood. Not only will this provide a decorative focus in a room but the terrarium will help retain the high humidity which these plants love.
Different plants will vary in their lighting requirements to grow and flower well. It is best to research the light requirements of your chosen plants and ensure the output of the lighting system is sufficient to ensure success.This can be done by carefully measuring the intensity and quality of light provided using a quantum light meter.
Generally a mid-green colouration to the foliage indicates the plants are receiving the correct amount of light. However, there are a number of problems that can be encountered and rectified. Seedlings that take on a bleached appearance or become stunted after growing under lights. Similarly, yellow-green foliage on plants nearest the tubes can indicate the light intensity is too high for the plant in that position. The intensity of light can be lowered by:.
This can also create problems with plant development, but balancing the number of red and blue tubes should correct the following problems:.

Why use artificial lighting Many plants grow well in a bright location in the home. However, the use of artificial light can be of further benefit in the following circumstances; For plants that need more intense light levels than are naturally provided indoors in the UK, especially during the short winter days For starting seedlings early in the year, rather than waiting for natural light levels to increase, resulting in stronger, more advanced young plants to plant out in spring For growing plants in a dark corner, windowless garage, where natural light would be too low For creating a decorative feature in a room, such as an illuminated terrarium full of foliage plants.
What artificial lights to use in the home Domestic light bulbs are unsuitable for growing plants as the light intensity is not enough and they are less energy efficient.
Here is a summary of the options available for the home. T5 High Output HO fluorescent tubes Readily available from horticultural suppliers, T5 HO fluorescent tubes have the following advantages that make them the current top choice: The intensity of light produced is generally strong enough to enable good growth and flowering when positioned correctly They are long-lasting about 20, hours They are relatively inexpensive They are generally economical to run, but not as energy efficient as LED Light Emitting Diodes lighting They give off comparatively little heat making them safe to place close to plants Other options LED Light Emitting Diode horticultural lighting is a viable alternative for indoor use.
How to use artificial lights in the home Plants absorb mostly blue and red light think of the colours present in a rainbow, plants use two particularly in order to grow and flower. Simple lighting system There are a variety of kits available which include an electronic ballast that starts up the tubes and reflectors to direct the light downwards onto the plants. In the home a basic set-up could be a unit containing two 60cm 2ft T5 HO fluorescent tubes suspended approximately 60cm above for example, a small group of houseplants, or crops such as leaf salads for fresh leaves during the winter months The lights can be on for around 16 hours a day Plants often require different light intensities.
The foliage colour is a good indicator to determine whether the plants are receiving enough light and the intensity can be adjusted to suit them See: 'Problems' below Seedlings These benefit from predominantly blue light to promote good growth and compact plants.
See: 'Problems' below Plant collections Phalaenopsis moth orchids and African violets Streptocarpus syn Saintpaulia can be grown under lighting very successfully and are tolerant of a variety of lighting conditions. Other plant genera Different plants will vary in their lighting requirements to grow and flower well.
Problems Generally a mid-green colouration to the foliage indicates the plants are receiving the correct amount of light.
Too much light: Seedlings that take on a bleached appearance or become stunted after growing under lights.The intensity of light can be lowered by: Reducing the number of tubes Repositioning the tubes further away from the plants Reducing the number of hours the lights are on photoperiod Too little light: Plants grow poorly and foliage is dark green. This can be corrected by: Increasing the light intensity by moving the plants closer to the tubes increasing the number of hours the lights are on Increasing the number of tubes Too much blue or red light: This can also create problems with plant development, but balancing the number of red and blue tubes should correct the following problems: Too much blue light with very little or no red light, results in stunted plants with dark green leaves, thick stems and few flowers Too much red or far-red light promotes stem elongation and tall spindly growth.

Growing Plants Indoors With Artificial Light For Plants
Willie Miller. Indoor gardening allows us to grow plants at home and use specific measurements. It is simple and requires little space, but taking care of the plants indoors is not an easy feat. Plants are autotrophs, meaning that they can produce food for themselves by using the light present in their surroundings. Certain wavelengths are required by plants to produce food for themselves. Grow lights provide an emulation of sunlight with all the necessary wavelengths.
Grow lights are one of the most important elements of an indoor garden. The change signals to the plant that it's time to start fruiting or flowering.
How to Use Grow Lights for the Healthiest Indoor Garden
Nobody wants spindly seedlings and leggy houseplants. Here's the best ways to avoid these sad situations with the help of artificial lighting. While many houseplants do just fine indoors with whatever natural light comes in your windows, certain ones can be coaxed to bloom more reliably or will grow more healthy leaves with additional light from artificial sources. And if you're starting vegetable and annual flower seeds inside, they often need the help of lights to develop properly. While the amazing power of sunlight is tough to completely replicate indoors, using grow light fixtures fitted with simple fluorescent or LED bulbs can come close. Here's what you need to know about setting up the best grow light systems for your houseplants and seedlings. Bright lighting is key to getting a jump start on spring transplants indoors. Most rooms do not provide enough light to produce dense, healthy seedlings. Even a south-facing window often falls short when it comes to the amount of time the sunlight can shine through. Seedlings will usually germinate well and produce their first set of leaves in a sunny window.
With the latest advancements in LED technology, you have more control over your yields than ever before. Your plants are covered in photoreceptors—light sensors that pick up signals from the light they receive. Plants use these photoreceptors to read the light spectrum and make decisions based on what they learn about their current conditions. It all comes down to the position of the sun.
Every gardening enthusiast is excited about bringing nature inside the home. We can accomplish thriving indoor gardening with the help of grow lights.
The Best Grow Lights For Indoor Plants & Small Spaces
Without using grow lights, maintaining an indoor garden can be tricky. Even if you have plenty of windows, certain species still may not receive the light they need to flourish. Window panes dilute natural sunlight and moving them even a short distance from the glass amplifies that dilution. There are many species of plants that are very needy when it comes to the sun. These plants will beg for more hours of light per day than even your largest south facing windows can provide. Grow lights are perfect for anyone without access to much direct sunlight or for growing plants requiring extra natural light.
The Benefits of UV Light for Indoor Plant Growth
Growing plants is a naturally pleasing hobby, but sometimes not all of us can afford to look after a beautiful garden or plant outdoors. This is where indoor lights come in handy. What if I told you that you can easily plant indoors using lights that are specifically designed to nourish plants? They can even provide them with all the necessary ingredients that the outdoor environment has.

Should I Use Grow Lights for Indoor Plants? What Type of Light is Best for Growing Plants Indoors? Can Any LED Light Be Used as a Grow Light?
The brilliant indoor benefits of LED grow lights
Light is one of the most important factors for growing houseplants.All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates energy. Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.

A grow light is an electric light to help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying colour, temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation e. Russian botanist Andrei Famintsyn was the first to use artificial light for plant growing and researchGrow lights are used for horticulture, indoor gardening, plant propagation and food production, including indoor hydroponics and aquatic plants.
EasyGrow lights were designed for the professional and hobby growers, it uses the most modern and efficient technology. The basic Mars Hydro model now at a special price.
One of the biggest difficulties we notice among our clients is their ability to assess the proper lighting for their plants. The human eye automatically compensates for brightness, which makes our ability to judge light levels deceiving. For this purpose, talking about light in terms of foot candles will do the trick. Although the term is anachronistic, foot candles are still a common form of measurement in the horticulture community. Foot candles are an imprecise form of measurement, but they give us a good idea of how much light a plant is getting. Once we have a hard numerical measurement of the intensity of light in a space, we can start looking at what plants would do well.
