Frequently Asked Questions (FAQ)

Can LED lights be full spectrum?

Yes, full spectrum LED lights can definitely be used to grow plants indoors. However, they’re not exactly as powerful as HID or High Intensity Discharge lights. They do a respectable job at growing plants, but they require more time to produce the same results.

Light intensity affects the rate of photosynthesis. No matter how your plants absorb the light, they will always be converting it into energy. The more intense the light source, the more energy your plants will be able to extract from the same amount of time. Don’t despair, however. The spectrum of LED lights is complete, so you will still be able to grow your plants efficiently. Expect slower results, though.

What lights do professional growers use?

Full Color LED grow lights are used by all commercial growers and gardeners. They are designed to produce the ideal combination of spectrum and intensity Your plants will also need to be kept under a light source that balances red, blue, and green spectrum, as dictated by their unique photomorphogenic needs. LEDs can help you maximize the benefits of grow lights in your garden.

What is the most powerful LED grow light?

An important factor to consider when looking for a grow light is the full-spectrum LED chips and the wattage. The best LED grow lights have a high number of full-spectrum LED chips. Plants are able to absorb more light with a higher flow rate.

In terms of watts, a 250 watt lamp is a good choice for plants and they typically last up to 20,000 hours. Cost efficient set-ups will have a lower wattage. For indoor gardens in particular, 200 watts is the sweet spot, as plants only need that much power to grow indoors. Plus, it will cost you less to get that power from the sun.


We looked at more than a dozen (perhaps even more) LED Lights and it was hard not to make the choice between the two best indoor LED grow lights. The case is similar to the best fish food for Betta Fish – you have the lower priced option made by a brand name (that is also friends with NASA), along with an industry upstart challenging the top model with fresh ideas.
