3 Major Types of Grow Lights

When exploring the world of grow lights, each type offers unique benefits and is tailored to various needs and stages of plant growth. Let's delve into the three primary types of grow lights used in indoor gardening: LED, Fluorescent, and HID (High-Intensity Discharge). 

LED (Light Emitting Diodes) Grow Lights

  • Energy Efficiency: LED lights are renowned for their energy efficiency, consuming less electricity compared to other types.
  • Longevity: They have a remarkably long lifespan, often lasting for several years without the need for replacement.
  • Heat Emission: LEDs emit very little heat, making them safe for close proximity to plants.
  • Spectrum Variety: LED grow lights offer a wide range of spectral outputs, including full-spectrum lights that closely mimic natural sunlight.
  • Cost: Initially more expensive, but the long-term savings on energy and replacement costs make them a cost-effective choice.

Why Choose LED Grow Light

LED grow lights are a top choice for growers due to their advanced technology and efficiency, marking a significant improvement over traditional incandescent, HID (High-Intensity Discharge), and fluorescent lights. One of the main advantages of LED grow lights is their energy efficiency, which means they consume less energy and produce less heat compared to traditional grow lights.

Beyond energy efficiency, LED grow lights offer a broad spectrum of red and blue, which is more effective in stimulating plant growth. Additionally, trustworthy LED grow light manufacturers such as Spider Farmer adopt high-quality diodes from Samsung and Bridgelux, contributing to more durable materials and a longer lifespan. 

Fluorescent Grow Lights

  • Intensity: Generally less intense than LEDs, making them suitable for young or sensitive plants.
  • Types: Includes T5, T8, and compact fluorescent lights (CFLs), each varying in size and efficiency.
  • Heat Emission: Emit minimal heat, but more than LEDs, requiring careful monitoring to prevent plant damage.
  • Cost: Less expensive than LEDs, offering a budget-friendly option for beginners or small-scale growers.

HID (High-Intensity Discharge) Grow Light

  • Types: Includes Metal Halide (MH) and High-Pressure Sodium (HPS) lights.
  • Intensity and Spectrum: MH lights provide a blue-dominant spectrum, ideal for vegetative growth, while HPS lights offer a red-dominant spectrum, better for flowering and fruiting stages.
  • Energy Use and Heat Emission: They are energy-intensive and generate significant heat, requiring proper ventilation and distance from plants.
  • Lifespan: Shorter than LEDs, requiring more frequent replacements.
  • Cost: Initially less costly than LEDs but higher operational costs due to energy consumption and heat management needs.

Light Intensity

Light intensity in grow lights is a crucial factor for plant growth, encompassing more than just the wattage of the light. It involves a combination of several specifications, including Photosynthetic Photon Flux Density (PPFD), Photosynthetic Photon Flux (PPF), and overall efficacy. 

PPF refers to the total amount of light produced by a grow light each second, measured in umol/s, and represents the unmanipulated measurement of a light's output. PPFD, on the other hand, measures the number of photons reaching a square meter of the grow area each second, quantified in umol/m2/s. This metric is essential for understanding how effectively plants utilize the photons, with different plants requiring different PPFD levels. 

For instance, cannabis in the vegetative stage needs a PPFD of 300-600 umol/m2/s, while in the flowering stage, it requires 900-1000+ umol/m2/s. 

Growth Light Spectrum

When looking for the best grow lights indoors, one of the critical factors to keep in mind is the growth light spectrum they come with. After all, not all grow lights offer a full spectrum. 

growth light spectrum

A full-spectrum light encompasses five distinct sections: UV light, blue light, visible PAR light, red light, and far-red light. This comprehensive coverage of all wavelengths of light means that a single full-spectrum LED grow light can support all stages and aspects of plant growth. Beyond its efficiency, using a full-spectrum LED grow light results in a more natural appearance for the plants, making it easier to detect and monitor plant diseases and pests. Moreover, a full spectrum grow light leads to higher PPFD, which is particularly beneficial for light-hungry medicinal plants like cannabis, allowing them to absorb more green light and enhance their yield. 

Spider Farmer offers efficient full-spectrum LED grow lights with dimming features, allowing you to tailor the light to meet the specific needs of your plants at different growth stages. Whether your plants are in the early vegetative stage or entering the crucial flowering and fruiting phases, the dimmable function allows you to fine-tune the intensity of the light to create the optimal growing environment.

Coverage Area

Knowing the dimensions of your growing space is essential before selecting an LED grow light. Whether you have a small 4x4 grow tent or a large commercial setup spanning hundreds or even thousands of square meters, the size of your space determines the type and number of lights you'll need. Smaller areas can utilize less powerful lights, while larger spaces require multiple large, powerful lights to provide even light distribution across the entire canopy.

    Looking to try something new. Recently shattered three vertebrae‘s in my heel looking for a used or sample light definitely do promotion of the light. Anything to pass the time till I can get back moving around. Anything would be an upgrade. Got a 3’x3’ flood and drain table. Working with 4 Samsung 350’s. Not happy with them. Gladly trade them in. Well thank you for your time. My bro Mel Hooks has a nice quad he’s sampling from you now. Saw what they do. The dimmers are wicked cool!!!
