  • Enhanced aesthetic appeal: A well-designed indoor garden can add beauty and tranquillity to your home.

Here are some ways to recreate a natural environment in your indoor garden:

  • Provide the correct amount of light: Most plants need at least 6-8 hours of sunlight throughout the day. If you don’t have a lot of natural light in your home, you can use grow lights to supplement.
  • Maintain the proper humidity: Most plants prefer humidity levels between 40-60%. You can increase the humidity in your indoor garden by using a humidifier or placing your plants on pebbles in a tray of water.
  • Regulate the temperature: Ideal temperatures for most plants are between 65-75 degrees Fahrenheit. You can use a thermostat to regulate the temperature in your indoor garden.
  • Use organic fertilisers: Organic fertilisers originate from natural ingredients and help to improve soil quality and promote plant growth.
  • Water your plants regularly: Plants need water to survive and thrive. Be sure to water your plants deeply and regularly, but avoid overwatering.

By replicating nature in your indoor garden, you can create a thriving environment where your plants can flourish.

What are the main things to consider when choosing an LED grow light?

When selecting an LED to grow light, there are a few main things to consider:

  • Wattage: The wattage of an LED grow light determines how much light it produces. Higher-wattage lights produce more light, but they also consume more energy.
  • Spectrum: The spectrum of an LED grow light refers to the wavelengths of light that it emits. Different plants have different light requirements, so it is important to choose a light with a spectrum suitable for the plants you are growing.
  • Efficacy: The efficacy of an LED grow light measures how efficiently it converts electricity into light. Higher efficacy lights are more efficient and will produce more light per watt of electricity consumed.
  • Coverage: The coverage area of an LED grow light determines how large of a space it can effectively light. Choose a light with a coverage area that is large enough for your growing space.
  • Price: LED grow lights come in a wide price range, from a few dollars to several hundred dollars. Choose a light that fits your budget and needs.
  • In addition to these main factors, there are a few other things to consider when choosing an LED grow light, such as the type of LED chips used, the warranty, and the customer service offered by the manufacturer.

Here are some additional tips for choosing an LED grow light:

  • Consider the stage of plant growth you are targeting. Seedlings and young plants require less light than mature plants and flowering plants.
  • If you are working in a confined space, look for a light with a narrow beam angle. It will help to ensure that all of your plants receive adequate light.
  • If you are on a tight budget, look for a light with a lower wattage. However, be aware that you may need to use more lights to achieve the same level of coverage as a higher-wattage light.

How is the light from artificial grow lights measured?

The light from artificial grow lights is typically measured using several key metrics to assess its quality and suitability for plant growth. These metrics help growers understand the intensity and spectral characteristics of the light emitted by the grow lights. The most common measurements include

Photosynthetic Photon Flux (PPF): 

PPF measures the total number of photons (particles of light) emitted by a light source within the photosynthetically active radiation (PAR) range, typically between 400 and 700 nanometres. PPF is expressed in micromoles per second (μmol/s) and is a crucial metric for assessing a grow light’s ability to support plant photosynthesis.

Photosynthetic Photon Flux Density (PPFD): 

PPFD measures the number of photosynthetically active photons that reach a specific area (usually one square metre) per second. It is expressed in micromoles per square metre per second (μmol/m²/s) & provides insight into the actual light quantity a plant receives at a given distance from the light source. PPFD is a more practical measurement for growers to determine light distribution within a grow space.

Spectral Distribution: 

The spectral distribution of light refers to the specific wavelengths or colours of light emitted by the grow light. It is often represented as a spectral graph, showing the relative intensity of light across the PAR spectrum. This information is essential because plants have different light requirements during various growth stages, and the best spectral distribution can influence plant growth, flowering, and fruiting.

Colour Temperature: 

Colour temperature is measured in Kelvins (K) and provides information about the colour of light emitted by a grow light. While it doesn’t directly measure the suitability of light for plant growth, it can give growers an idea of the light’s appearance. Many cultivators favour growing lights having a colour temperature between 5000K to 6500K for vegetative growth and 2700K to 3500K for flowering and fruiting stages.

Luminous Efficacy: 

Luminous efficacy is the factor that determines how efficiently a light source converts electrical energy into visible light, usually shown as lumens per watt (lm/W). Though it is typically more applicable to general lighting, it can also offer valuable information regarding a grow light’s energy efficiency. 

Foot-Candles (FC) or Lux: 

Foot-candles and lux are units used to measure illuminance, which measures the amount of visible light reaching a surface. Although they are not specific for plant growth, they can be applied to assess the brightness or light intensity for general illumination in a growing area.

Daily Light Integral (DLI): 

DLI measures the total amount of PAR light received by plants over 24 hours. It is crucial to determine whether a grow light can provide plants with sufficient light for their growth requirements.

These metrics help growers choose the right artificial grow lights for their crops and growth stages, ensuring that plants receive the appropriate light levels and spectrum for healthy and productive growth.

What wattage grow light do I need?

The wattage grow light you need depends on the size of your grow space and the type of plants you are growing. Here is a general guide:

  • Seedlings and small plants: 10-20 watts per square foot
  • Vegetative growth: 30-40 watts per square foot
  • Flowering growth: 40-50 watts per square foot

For example, if you have a 4×4 grow tent, you would need a 500-600 watt grow light for flowering growth.

If you are growing plants that require a lot of light, such as cannabis, you may need a higher wattage to grow light.

It is also vital to consider the efficiency of your grow light. LED grow lights are more efficient than HPS or MH grow lights, allowing you to use a lower-wattage LED grow light to achieve the same degree of light brightness.
