The Best 1000 Watt Grow Light on the Market – Buyers Guide

With various types of grow lights available on the market, it can be quite overwhelming to pick the right model that will suit your growing requirements. Seeing the range of options available, we have decided to create a buyer’s guide that highlights the best 1000 watt grow lights.

This guide will include their benefits and the features they offer. You will also discover what factors you have to consider when selecting a grow light system.

First off, here are a few questions you want to ask before heading out and buying the first grow light you see:

  • Do you plan to grow all year round, or do you intend to start your seeds during springtime?
  • What types of plants do you want to grow?
  • How tall do you want your plants to get?
  • Where do you intend to put the light – somewhere open like a living room or tucked away in an attic, basement, or designated grow room?
  • Do you want the light to be mobile?

Answering these questions can help you understand what 1000 watt grow light is best suited for your growing needs.

Before we dive into listing the best 1000 watt grow lights on the market, here is a summary of everything you need to know about grow lights.

Everything You Need to Know About Grow Lights

Every green plant requires sunlight for photosynthesis: the process where specific plant cells transform the energy from light into sugars. It is this process that causes plants to release oxygen. The amount of light you need generally depends on the plant itself. Fruiting edibles like tomatoes require a lot of light, while dracaenas require very little light.

Every plant in its seedling stage requires a lot of bright light to grow. When seedlings don’t receive a sufficient amount of light, they can become leggy and weak. In most cases, a windowsill cannot provide enough duration or intensity of light required, particularly during the winter.

What Lighting Terms Should You Take Note Of?

  • Color: Color is the term used to describe how the light looks. The majority of grow lights produce full-spectrum light. Plants tend to use red and blue light, representing the warm and cool ends of the spectrum. Green and yellow lights are less used by plants. Red light stimulates the production of fruit and flowers, while blue light is for vegetative growth.
  • Duration: Duration is simply used to measure the number of light hours a plant gets in an entire day. This can be affected by turning lights off and on or simply using a programmable timer.
  • Intensity: Intensity is the term used to describe the amount of light that reaches a surface at a particular distance from a light source. For instance, an extremely bright LED bulb 1 foot away from a surface offers the same intensity as a closer but dimmer bulb 2 inches away.

Should You Go for Fluorescents or LEDs?

While fluorescent and LED light can create full-spectrum light, LEDs are way better for the environment and your wallet.

LEDs are great for plants; you simply need to find the right grow light that is calibrated to meet the needs of an indoor plant. This means an added blue light boost to help enhance photosynthesis, stimulate rooting, and promote peak growth. LEDs also do not give off too much heat.

LEDs can have a higher upfront cost, but they are extremely efficient. An LED uses half the electricity used by a fluorescent light and lasts five times longer. It also helps that grow lights are environmentally friendly, free from mercury, and unlikely to shatter like glass.

On the other hand, fluorescent lights are more affordable, making them a great choice for those just starting their indoor growth journey. At no point should you consider a conventional incandescent bulb, as they aren’t suitable for indoor growing. In addition, these bulbs tend to give off too much heat, which can burn your tender foliage.
