Monkey and a football.. LOL Almost spit on my screen.. Absolutely love the content.. This is my favorite generation when it comes to learning some stuff.. Thank you for all the free knowledge.

[@jimmack3968]

Been growing for many years now coming up to 30 and love this guy. I would love to follow him around in his garden picking up more growing wisdom. 👍

[@taticonners1940]

Yooo!!! i just stumbled upon this channel accidentally while searching for a break down of fertilizer so i could learn a thing or two about my recently started garden of plants so i didn’t end up killing them. And let me just say- i love how you explain everything so well and make it simple enough that a rookie gardener like me can even understand it!! And you are funny as heck and super down to earth. I really enjoyed this video and feel like i learned a LOT!! I can’t even begin to tell you how many videos i have been watching that taught me absolutely nothing-in fact i had more questions after some of them than i did before watching them!!! Most of them are just people over complicated things and using terms and products with unfamiliar names a newbie like me has no idea about, and so many confusing soil amendments +additives foliar sprays bloom boosters organic and inorganic fertilizers etc that they tell you are all necessary and have some complex order and system to them, and the ones that don’t are mostly just trying to sell you somthin. This has been the first one i hav seen that is just to the point and soley for the purpose of informing and helping people actually learn. Its been the first video that i actually understood clearly and concisely! So glad to have stumbled upon this. Thank you so much for putting this content out there for people to watch for the free and gain so much helpful knowledge. You really don’t even know how much it has helped me , as im sure it has helped many others as well. Super appreciate the video and all of the great information in it as well. Thank you again for taking the time to do this and for spreading the knowledge and love of gardening. Keep it up!!

[@napoleonsmith7793]

We need you back. Just found you and its been a year since last video. Good stuff.

I'm glad to see you back, Robert. No matter how much you know, you can always learn a thing or two from a brief class. I wish you well.

please, please PLEASE, don't stop making these videos! I have just found you, and it seems im late! 6 months ago was your last video, i do hope you carry on!

Dude, I look forward to every video you post. I get more information from you in 10 minutes than I do from 2 hours of reading. I'm an organic grower that anticipates every bit of information you're willing to share. I hope you get a grow going very very soon.

[@DiscoStuLikesDiscoMusic]

people need to listen to this man!!! I've been checking out bruce bugbee lately and he recommends Peters brand fert and a 20:10:20 ratio for veg, which is very little difference from your ratios that you prefer and when you got the levels dialed in you'll get a good crop. thank you for the video. your knowledge is in line with college horticulture professors studying cannabis research

[@Lisciousw]

Does he give a mix ratio? Now much per gallon?

Good to see you man! Sorry about the grow but glad to see ya back posting again. Prayers to you brotha

[@michaelkelleher714]

Thank you for your time making this information so straight forward and crystal clear. Awesome wisdom very well presented. without all the bottles/containers. I'm in my first ever grow. Under led lights. My plants are into week 6 of 8 of flowering. The flowering fertilizer I'm currently using has an N-P-K of 2-11-14. So, during the flowering cycle, I should be using 0% to 5% Nitrogen? I meet that one. And higher Phosphurous 30%-35%. I'm well off the mark here. And higher Potassium 20%-30%. I'm well below this. A good N-P-K for flowering Cannabis would be 0-30-25? I've been using a Cal/Mag additive since early veg and intend to do so until the end. Thanks if you could let me know your thoughts. Great work man.

[@jimg5619]

Thank you! I just learned so much more about fertilizer and an better understanding of the uptake process of the plant. I'm just starting indoors over the winter. Very informative 🖖

[@daveshisler4851]

I really appreciate you and your classes regarding everything grow! It’s all so helpful. As a first time grower, using hydroponic drip and drain to waist, I could really use some advise on SPIDER MITES! I noticed the problem at the end of veg and just before flipping. Now I’ve tried everything suggest on you tube, and they just won’t die! I haven’t seen anything suggested by you. Have you done a video on this topic? I can’t find it. I’m now going into 3rd week of flower and I’m very concerned I could loose the whole crop!

Great info

[@Brovillion559]

My uncle was 63 when he passed in 2019. He grew some really good outdoor. He trimmed the plants when they were bushy and that was about it. A little more attention and affection they would have been great but that’s my opinion. He said never ever use store bought anything, Mother Nature provides everything, you just need to go get it. He would filter his water through soil, rocks and all sorts of stuff. Kinda like a river does. Anyway he said understand what’s in your soil and the plant will do the rest. She will tell you what you need. He grew 10ft plants that gave a pound or more (not to sure). I used chemicals when I first started out. 1 grow and I went to organics. I use his methods and it’s amazing.

[@davewitty3307]

I’m excited to test your fertilizer recommendation on my next grow. I’ve always used a 4-4-4 and tea. Happy with the results. Maybe this will up my results. I’ll follow up in 5 months.

[@shanhuber]

Great video, you are incredibly knowledgeable, and I really like your advice. You remind me of an old high school science instructor, and he really made an positive impact on me. I have several question. First, how often do you fertilize. Second, how much of the solution (following the bags recommended solution concentration) are you putting on each plant. Lastly, what do you recommend for a soil, as I am currently using coco coir and am open to other options, and would love to hear what you use.

[@Judge_420]

Im glad to see you. I miss you . I hope you and your family are ok ❤✌🏼

[@look2305]

comming back !? nice wishes from germany🎉

[@CovidStinks]

Appreciate your training videos 💯 You mentioned what NPK % you use based on HP or LED lighting but could you please educate us for outdoor natural lighting? I grow in a greenhouse, water daily and feed twice per week. The temperature averages 120 during the day so the plants uptake quickly and perspiration quick. I applied misters on timers to avoid canoeing. My plants grow very well but looking for the added magic to finish adding more weight. You're advice is greatly appreciated. Cheers 🍻

[@jweezy8645]

Anyone know what happened with this legend? I just came across his channel started watching today and within the first 2-3 minutes I was like “this is my guy!” Lol. Hated to see his videos abruptly stopped

Hello Robert Good to see u back on youtube. I missed u. Last time I seen u , was the fire. Your looking good . Time to start the show. I always used HPS with success. Now I'm trying 650 watt LED bar light & 2 dimmable 400 watt HPS , 1 on each side, and side led lighting migros on all walls . I will shoot for 1,000 par across. Equal and see what shakes out. Using CO2 . How would u feed this light mix system ? 4'×6'×96"expandable roller tent to 6'×6' if needed. Using 8 inch grodan blocks . Did u save any Maui wowie?

[@camarodude9615]

I just ran across your channel,sorry to see the devastation you went through,keep your head up!from the videos of you your a cool old cat from way back with a tons of knowledge

[@3beerbob]

Great info Robert! For the small grower - how do you mix the Nutriculture on a small scale - say for 5-gallons of water with the 15-5-15? Do you normally ramp up your feeding schedule as the plants get larger during the veg phase?

[@weedseeds5211]

Brother you need to get back in the growing game. Lets get it!

[@jessemine1556]

Dude, you’re awesome

[@TJETHCA]

Is there any way you can make a video for a beginner I could really use that video to start and I’d honestly would appreciate if you did it because I actually learn when I watch your videos it’s actually inspiring. I wish I could shake your hand to be honest!

[@dannyarmata8878]

Im using peters orchid fertilizer 15-5-15 with the extra Ca & Mg, its working great and WAY cheaper than "cannabis" nutrients. TY old school ive learned some good stuff & ive neen growing since 2014

[@OldSchoolGrowing]

Thanks for the good info!

Oh man, i hope one day brazil will have videos and masters like this ! Today weed is illegal here, and are so many growers hidden chasing their dreams 🔥

[@themotuman2663]

I've been having so many problems with the "fancy" ferts. So glad to have found this video. There's just 2 crucial pieces of information missing from the master... How much, and how often. So much conflicting advice about that. Weekly, bi-weekly. A teaspoon. 3 teaspoons... 🤦 So frustrated. I hate learning by failure.

[@vincentpcappello4512]

Sorry to hear about the fire I hope you get up and running again soon!

Hi Robert. My name is Sean , I grow recreationally @ home. I like your results and have adopted many new techniques from you tutelage. I am using the same 15-05-15 (N-P-K) 4%cal and 2% mg. What p.p.m's should I use in vegitation? Thank you for showing me the way!!! I,m OLD School myself nearing retirement!

[@gavinnelson5298]

I love the videos man sorry to hear about the fire but I been thinking will it help the grow process if I put worms in the soil 🧐 or does it mess with the cemetery 🤔🤔

[@MrArtifacts205]

From what I’ve been searching 1 teaspoon per gal 15.5.15 1/2 teaspoon per gal 10.30.20 I personally feed then water then feed. If I mix the two, I do 4 half teaspoons of 10.30.20 and 1 half teaspoon of 15.5.15 in a five gallon bucket of water.

[@zygeekmusic]

Can you go more into why you still use some N in flower? How different would this be with an organic fertilizer like Dr. Earth?

You could always consult to make money until you can start back up. That is the worst though business wise, I really hope your luck turns around. I am sure with your knowledge you will be in demand 😊

[@assog5737]

Like you, I've been enjoying and growing cannabis for over 50 years. Also like you I tried every bullshit line of nutes on the market. Not one was better than the other. And the cost of all these products with their added fillers, whatever they may be. Is a total rip off. And plus I was never happy with the results from these products. I new the plants should and could do better. Don't get me wrong I've grown thousands of killer plants over the years. But to me it just seemed like something was holding them back. From reaching their true potential. Well about 10 years ago. And totally by luck. I was introduced to this well educated gentleman. Who has been schooled on this subject. And who has performed hundreds of experiments on this subject. I was very lucky that out of the kindness of his heart. And the passion he has for this subject. He took me under his wing and tried to teach me what my old brain could handle. The hardest part for me was trying to completely change my thought process on this subject. Which by the way was completely incorrect on most of the things I thought. Anyway to make a very very long story short. He convinced me that ALL premixed nutes with their additives and fillers are a total waste of time and money. There is hundreds of reasons why. Which I won't go into. But what he proved to me is that mixing your own nutes. Is the only way to get any kind of plant to reach it's full potential. Which means that you purchase pure N. P & K and everything else you need. And mix your own solution. This way you can control what and when and how much you give your plants. With no additives or fillers. And I'll tell you what. The first grow I did this with was the best grow I ever had in my life and I've never looked back since. And you want to know one of the best things about doing this is the cost. I spend like a tenth of what I use to spend for nutes. And plus it's really simple. I can't believe over the years I never thought of this myself. It just goes to show that no matter how old you are. Your never to old to learn new things. Good luck everyone. And take care. ASS OG. AeroSystems SeaOfGreen.
