No bongs,no stupid music, just real education great video 🤘🏼 life's a garden dig it 🤠

Playing this content in my backyard so my plants can listen to it too.

This never gets old. Thank you a million times Harley!

best horticulture lectures on youtube period! Thanks so much to Harley Smith for producing and sharing these easy to follow, educational videos!

I've taken a lot of classes, read tons of books and everything else and Harley makes everything simple, easy to understand for everyone, and then explains how you can actually make real changes to fix a plant's issues to grow amazing plants. Thank You Harley & NPK for giving people the control over their plants and educating us all in how to be experts.

In my opinion Harley Smith is by far the most knowledgeable speaker about plant growth and biology I've seen so far. Keep up the great work! Never lose that passion.

Harley is the GOAT we are all in your debt sir Thank you for your time and knowledge

The best I’m listening to so far……Outstanding

❤❤❤ wonderful information. Thank you Harley for sharing.

Over the years I have seen and heard of many persons claiming to be so called ''plant doctors'' but for Harley this title is well deserved in my opinion, he is absolutely in a class of his own. Thank you so much for sharing your knowledge you are a 1st class lecturer.

You are what they call "Gold" in the grower community!. .Thank you!

I just ordered your whole line of products Harley. Your videos are on speakers in my house on loop daily lol. For so long I've been annoyed with nutrient companies because of the fact that we don't have control of the multiple ingredients/macro micro nutes that they load into there products. Im hoping to have a more tactical and direct way of feeding with your products. They'll be here in 2 days. Keep it up Harley and NPK, we're watching

The ppl that disliked this video must be upset he's sharing the knowledge. Thanks for explaining it simply.

How nice it is to see such a capable and passionate person explain a subject with such wisdom and commendable disinterest. When this happens is when I think how lucky I was to take English language classes. This brings me closer to the knowledge and to enjoy a real lesson in Agronomy. From my beloved land of Argentina, I stand up to applaud you master.

just ran across your YOuTube - NPK University. GREAT!!!

what a nice lad! perfect explanation of the matter. Harley Smith: thank you sir!

This was one of the most informative plant videos I ever came across

Thank you very much for share and teach. I has a long time waiting for informations like this. Continue please thank you

I've taken some of Harleys classes he is the best and he really knows his stuff. He is taught me so much about the elements that I am getting explosive plant growth in everything I do and now I can almost immediately diagnose what each type of plant wants or likes. NPK makes excellent products too, they're very concentrated and a little package will probably last you years. You can tweak things at specific times of grow or bloom and what they are is the raw materials every major fertilizer company's fertilizers. Except they're in the most valuable dissolvable form and top-notch. I like them so much I become a dealer. And yes this does apply to the marijuana cannabis industry as well. Many people want to know that because they are growing their own medicines and want good production and the highest quality. Harley can definitely teach you everything about quality. I'd rate him as probably one of the best plant biologists in the world, and he's been all over the world. I periodically come back to his videos to refresh my experience so I don't forget things. Sometimes it does take a while to absorb but if you do it over and over again you'll get it and you'll be glad you did. Thanks Harley and thanks NPK for this video. You guys rock. Robert Sandera

The best content I ever seen about plants nutrition. And I was reading/seeing ton of stuff. Thanks for informations!

Harley Smith is my new hero! I really like how excited he gets teaching about plant anatomy and nutrients. You can see he enjoys teaching and it makes me pay attention. Thanks Harley, for all you do.

Always keep coming back to learn, and refresh on all things N-P-K! Micro and Macro nutrients always important to remember!

Your energy is mobilizing even more than plant nutrient an mineral transport! Subscribed!!

Thank you for sharing your wisdom. It is greatly appreciated.

Awesome video! Trying to get into a little gardening armed with years-old animal/human physiology background, but very little plant physio knowledge. Video was very helpful. Thank you.

You're the best Harley. Thank you. I agree with your philosophy of free information. Love the physiology.

Man thanks so much for this and all your videos! This video has increased my understanding of how everything works and has brought all the scattered information I've learned full circle! You have a great way of teaching and making these things understandable, thanks again.

Such a wealth of knowledge being shared thank you for these video's they have been really helpful and the way you explain everything has been real easy and fun to learn from you. I have been using the florescent 6500k and that has really kept the plants from stretching during veg that really helps when growing indoors. Thank you for sharing

Thank u The information about when too add phosphorus and when too add potassium was priceless

Thank you for your efforts, really appreciate it 🙏 God bless

thanks Harley. you are the best

This was both informative and lit. Thank you.

Just subbed I love the willingness to teach

Very informative. Thank you for posting

We need more people like you much love✌️ Harley Smith

Great class !

I have watched this video probably 200 times (yeah....I ain't got shit to do but watch plants grow). I always catch something new almost each time I re-watch Harley Smith videos. Today I learned "I NEED TO BACK OF THE POTASSIUM!"(29:48). I frequently have an issue with just a few leaves turn yellow here and there during heavy flowering and I thought it was a Mg deficiency. I now think it's the extra Bloom, PK Boost, and added NPK RAW Potassium I'm feeding my plants during flowering that is giving me a potassium toxicity.

You are such a nice man Sir ! Thank You a lot for all of Your knowledge!

It is so much better to hear this from someone who is not stoned. Thank you.

just bought the raw line. love the videos Harley

Wow! Thank you for this!!!

Dont count out shop lights just yet. Lithonia cp high bay shop lights at lowes now has a full spectrum light in either 4000k or 5000k with high blue high red and shockingly higher greens and yellows and oranges. Half the price of a* grow light* all of the benefits. A 200 watt 400 equivalent [18k lumens] will grow 4 medium plants in a 3x3 tent. I've done extensive research, the lights are solid!
