Do I need a lot of LED grow lights?

How many lights I will need for my hydroponic garden is one of the biggest queries. How many plants you’re growing and the size of your grow space will determine that.

You’ll see that LED grow lights are categorized by wattage when looking for them for your hydroponic hobby garden. LED grow lights typically have wattages ranging from to, with a higher wattage corresponding to a larger grow area.

The conventional wisdom used to be that you needed about 40 watts per plant you were growing, but with these new LED grow lights, things operate a little differently. The coverage area will vary depending on the type of LEDs used, the driver, and the grow light’s shape.

I would advise just following what each light manufacturer recommends for that particular grow light rather than trying to estimate what you need beforehand.

The product description ought to include information about the coverage area. Keep in mind that during the flowering and fruiting stages of the plant, the coverage area of your LED grow light slightly decreases.

It’s not always a good idea to purchase one light that illuminates your entire coverage area. To ensure that your plants are getting more light from all sides, I advise having at least two lights.

The Various LED Grow Light Types

I advise buying lights with a daisy chain feature if you intend to use multiple grow lights in your hydroponic garden.

Using the power cord, you can daisy-chain multiple lights together. Because fewer outlets are required for grow lights, more outlets can be used for other system components. You can only connect a small number of them at once, so be sure to check the manufacturer’s recommendations for the ideal number.

Switch to Veg And Bloom

Most LED grow lights are full-spectrum, which means they will generate the light required for all phases of plant development. However, how some LED grow lights provide that light may vary.

Some grow lights have a single switch for both on and off operation. Smaller lights typically have only one switch. Typically, larger lights have two switches. One veg switch and one bloom switch are typically present in two-switch LED grow lights.

How to Buy an LED Grow Light: What to Look For

You’ll find a range of prices when looking for LED grow lights for your hydroponic system. Even though low-cost grow lights might not be ideal for producing top-notch plants, they can still be useful for the majority of hydroponic hobbyists. You do, however, get what you pay for.

Warranty and quality assurance are provided.

The majority of manufacturers provide some kind of guarantee or warranty. When examining warranties, it’s important to consider both the duration of the warranty and what is covered.

Look at the testimonials.

I always read the reviews before deciding what to do. When reading customer reviews for products you’re considering for your hydroponic garden, there are a few things to keep in mind.

  1. Look at the number of reviews a product has. Reading reviews collectively will probably lead to a more accurate conclusion the more reviews there are.
  2. Negative reviews don’t always imply a subpar product. Sometimes reading a bad review makes me think that there was more user error than anything else.
  3. Check out the images the reviewers include in their writing. Aside from the light itself, observe how their garden is maintained. A healthy-looking garden is always a good sign, but keep in mind that if something seems off, it could be caused by something other than the light.


One of the most crucial components of an indoor hydroponic garden are grow lights. For hydroponic hobbyists, LED grow lights are the best option, and there are many to choose from. Before buying LED grow lights for your hydroponic garden, be sure to follow the advice above and do your research.
