LED Grow Lights Buyer’s Guide
Wattage is a key consideration when choosing the appropriate LED grow light. Plants need a lot of light to grow, but too much light can result in browning or yellowing leaves.
The amount of watts you need will depend on the plants you are growing. Fruiting plants like tomatoes may need up to 32 watts of light per square foot of growing area. In contrast, leafy plants such as salad leaves will only need 10 to 20 watts per square foot of growing area.
You will need to measure the growing area to ensure that the light you choose provides enough to cover the whole area evenly. Most LED grow lights specify the coverage at certain heights in their description.
LED lights cost less to run than traditional High-Intensity Discharge (HID) lights. In addition, LED lights produce less heat so you will not need to use as much energy cooling as you would with HID.
Until recently, LED grow lights usually provided red, blue, and white light. However modern grow lights are full spectrum which means they provide all the colours in the light spectrum. Full spectrum lights are the most similar to natural sunlight and can, therefore, support your plants well through all stages of the growth cycle from seed to fruiting or flowering.
The best LED grow lights for the UK market come with a 2 or 3-year warranty that offers extra peace of mind.
How far should an LED grow light be from my plants?
LED lights can be placed much closer to plants than HID light because they give off less heat. This is a great advantage as it means the lights can be placed closer to the plants and this means the light can penetrate the canopy of the plants more easily. In addition, it means you don’t need such a tall growing space.
Getting your LED light the right distance from your plant will result in strong healthy crops with no burning or yellowing leaves. When your light is placed too close to the plants you may see bleached or yellow spots on the leaves. As well as burning your plants, if the LED is too close it can result in nutrient deficiencies for your plants.
However, it is not always easy to calculate how far away your LED light should be as this differs depending on the size and wattage of your lights. It’s best to check the directions that come with your grow light and follow their recommended distances.
However, in general, you should aim for the following distances.
200 watts 12 to 20 inches
250- 400 watts 16 to 30 inches
450- 550 watts 20 to 30 inches
600- 800 watts 28 to 42 inches
What size led grow lights do I need?
The size grow light you need will depend on the type of plants you are growing as some require more light than others. However, the following is a guide to the wattage you might need to cover your growing area.
An area of 60 x 60 cm will require 50 – 200 watts depending on the type of plants
An area of 80 x 80 cm will require 200 – 400w depending on the type of plants
An area of 100 x 100 cm will require 400 – 800 watts depending on the type of plants
The best LED grow lights can help you start off plants much earlier in the season leading to bumper crops of tomatoes and chillies. In addition, grow lights can support your house plants including orchids and succulents through the winter months so your home always has a tropical vibe.
I would recommend the VIPARSPECTRA Reflector-Series V450 450W LED Grow Light as it uses high-quality LEDs is quiet and cool and has both veg and bloom settings so will see your plants through the entire growth cycle.
