3 Things You MUST Know Before Buying an LED Grow Light 🌱💡

LED grow lights are some of the most confusing pieces of grow technology on the market, and made more so by LED manufacturers purposefully confusing consumers in their marketing materials. Learn how to TRULY evaluate a LED grow light's performance for its price range in this video. We'll cover some basic terminology like PAR, PPF, PPFD, and photon efficacy.

Then, we'll get into a few different misconceptions:

1. LEDs are better because they use less power.
2. Total potential wattage vs. actual diode capacity used.
3. PPFD numbers are to be trusted from manufacturers.

Professor of botany here. Great job explaining this- you've got it bang on the nail! I'll be showing this to my students.

Best explained terminology on LEDs.when I first looked up what lights are worth purchasing I thought this stuff would be somewhat difficult to learn but it really ain't, very informative for beginners.

[shawnspencer]

One of the most informative LED light guide videos I've seen yet. Great work brother. I really enjoyed this

[cooperthomas]

This is by far the only video out here that I could find that explains terminology thank you 🙏🏻

I'm only "growing delicious food" officer.

You sir... are a gentlemen and a scholar. Thank you for giving me the knowledge to make an educated decision. Thank you for suggesting this light and appreciating the vendor for sending it to you to demo while still being humble about it.

“Here is the science, here is the math, here is the light I like.” I feel like after I start comparing lights this one will just speak for itself.

“Do not buy a light without seeing the floor chart” is my biggest take away.

A REAL gardener talking? The sensible points to shopping for high performance grow lamps are covered here. Thank you Epic Gardening.

I've had this stuff explained to me a bunch of times & this is the first time I've actually understood it, so thank you!

I found a 4300 lumen LED shop light for $15. It worked so great I bought another one. I'm starting seeds so it works great for me.

[sharazod]

Wow oh wow I was just getting ready to buy some lights and thought it would be a good idea to see what people say about them. Thanks for the information! Makes me better informed😊

Wonderful video.
This creator is a great example of how to grow a channel.
I first saw him foraging for food, when that was all the rage. He is now into hydroponic farming which is now the rage. He is adapting to what consumers want to learn about and is not confining himself into a single subject.

If you studied to prepare for this and present this fantastic dissertation to us, thank you! Best explanation I've seen yet. Thank you for your efforts to share this knowledge.

As an electronics technician, I really appreciate your breakdown. Great video. Trying to save an aloe plant that has lost all its roots due to my total lack of watering for months at a time.

This video made me feel like I was in school again and the teacher is talking but I have no idea what he's saying

[PrimeBrawler]

Thank you, this was one of the best videos I have ever seen about LED lights! I literally had to pause every minute and whip out a notepad to write this shiet down. So much information. I think I'm ready to buy some lights now!

[ivyrose]

As a beginner, this video was soooo helpful! Especially the beginning. QUESTION: Where do we find the table of PPFD charts? Is it usually on the manufacturers website or in the description of the product?

[cherylhughes]

Thank you. Your video was informative, enlightning and relatively easy for me to understand (mostly)! I'm going to try going beyond my aero garden with some larger plants, as well as the Kratky method. I'm looking forward to watching more of your videos!

[irisandrea]

You literally have everything I need. Haha. I'll be transforming our old refrigerator to some sort of seed starting station and I'm currently looking into grow lights. Thanks as always Kev!

[charlesfurer]

Wow, just wow. Ignorance-stomping, real information, delivered efficiently=GOLD!! Thank you.
