Your videos have helped me an immense amount. Love the content man, thank you for all that you do.

One thing I'd add, at lower humidity the plants will take up (& transpire) more water, if you are fertigating (adding nutes with the waterings) then the plants are also uptaking more nutrients as they cycle though the water & you may need to reduce feeding strength to avoid nutrient burn when you are growing at reduced humidity (RH below ~ 50% )

So much useful information in this video! Now to find a way to put all this to good use. Thanks, especially for presenting everything in such an easy to understand form.

Thank you very much for the knowledge, mister, you don't know how much I appreciate your videos. I will be a successful grower one day and I'll thank you for that as well. I send you a big hug, man, hope you are doing great

I've been growing for some years but I find myself straying from the basics sometimes and videos like this really help me just go back to how I usually do things I find your videos really useful I also would like to mention the senelux se 4000 I bought it but I had it boxed away but for a budget price light I found it amazing compared to the hps lights I used to use I've only used it during veg but the difference is amazing thicker stems and much bushier than I usually get from HP's also the nodes are much closer together because of the climate I'm in I do used HP's during flower with led just to help increase the temperature because I find the heater uses almost as much electric. Thanks 👍

I use to grow HPS only, no more however. I picked up this light and it is everything it says it is and more! My yeilds are bigger, buds are very tight, and trichromes look like frosting on the buds.. I purchased the timer as well, it all works like a charm. I use full power for 3 hours, them drop to 75% for 10 hours, then 50% for 3, them the light shuts of them I switch to my moonlight led for 8 hours... I have never seen my plants grow this fast, and this healthy.. Truly one amazing LED..

Love the video Shane! It has a very high end production feel.

Protip: Don't use tap water in a humidifier if it doesn't have a filter. There's nothing like finding your grow space covered in a nice coat of powdered calcium.

one of the best channels on youtube for sure ! thanks for what you do !

Hey Shane Your tip about covering the soil, I mulch with bark chips between veg and flower and find works really well. I do everything to reduce evaporation, at this point because it's no longer helpful. I also put my fabric pots in buckets, which reduces evaporation and allows me to switch to watering from the bottom up which also helps. Bluetooth hygrometer/thermometers of amazon helped me get to grips with this. Being able to see your readings as chart is so helpful. They'd be worthy of a video just so more people started using them. Thanks again, I mine your channel & DrMJ for info and always find the light. C-weed

Very smooth and informative flow of knowledge. I had my lights too high by following manufacturer recommendation. Now I know I need to lower my light level due to light stress. Thank you.

Love your vids but would love to see more with Migro range and Migrow lights in various tents...They're beautiful impressive lights.

This is one of the most interesting things I’ve ever seen on RU-vid, thank you so much for you knowledge G stay lit 🔥

Great info. Thanks...I just hung my grow300 in my 2x4. And I just put in a order for the SpotOn par meter. This dude super smart and that's why I buy from migro.

Sound reasoning and great advice Shane. Thanks for putting this reference video together.

Amazing video! Your channel has such great content. Greatly appreciated 👍🏼

Thx for the clean, detailed video. On point, no frills. Vast knowledge condensed for the unknowing and lazy. I like

Excellent information as always Shane, apart from using an upside down temperature VPD graph @10:29, this is a very useful video.

Thank you so much for all the hard work put on this video !!

Very informative, love the charts and graphs. Well delivered also.

You'll help many growers with this helpful and very useful information. May you continue to share your knowledge with others.

I have to say you are awesome I really like all the knowledge you pass on for free thank you you rock, shout out from New Hampshire USA

you're the best growing teacher to me 👍 Since working with fluence led 's everything got complicated, but your lessons are a great helping hand. 💯👋 Also i do like your serious appearance a lot. Thanks a lot for a better understanding what I am doing. 🤗

Great video! One question and/or comment. I read years ago, and I got incredible results by following what I read, that keeping the grow room temperature as low as 68° is the best way to keep all of the extremely volatile terpenes accumulating on the buds and not taking flight. My hydroponic plants didn't smell much below 70 ° but the smell was impossible to contain at 75°, as quality decreased. I think a lot of commercial weed is grown for maximum yield and not for maximum terpene content.

great work mate love your content . will be getting one of your lights shortly . keep up the great work.

Great stuff, as always. Thanks Shane. You da man.

Thanks for the share! Love your show Shane! Great knowledge.

Big respect as always MiGro. The channel of yours, and another big grow channel have gone from 5000 to 50,000 in literally 1 year of educational video. Keep up the great work, and professionalism.

Kept it simple to the point, explained so clearly thank you!

Very good summary, and VPD is key to an optimum yield. As Shane says, the taller the plants the more humidity you'll need and therefore the more fans you'll have to put in the grow room as ventilation is paramount to avoid bud rot. Icmag forum has a very good thread by a very experienced grower named DJM if you are curious about that VPD and high humidity management.

Great info as usual Shane, appreciated 💚👌

Been watching for a while, realised I wasn’t subbed. Thanks for you efforts!

If you wrote "A Guide To Growlights For Dummies" I would certainly buy it. When you explain all this it starts making sense but for those new to growing with grow lights, this type of information may as well be Greek. My goal is to grow my food in the winter in my basement so that I don't have to heat a greenhouse or worry about snow load. Much gratitude for your advice and education with respect for your ability to teach others and your willingness to share what you know. I see your lights are on sale and am working on a budget as it seems like I will need quite a few to grow enough for two people assuming that if one can grow a plant to the flowering stage using LEDs, I could potentially grow vegetables or at least root vegetables this way. Still doing the math.

You do a excellent job on explaining the the details great video thank you for sharing your knowledge

Thanks Shane, very well put together video 👌

VERY helpful video, mate. Thanks so much!!!

Great information thank you very much! on my first grow here I'm going to put this new found knowledge to work!!

thank you for the great information 😀 keep it up and thank you for all the amazing videos

great vid. simple, easy to follow, brilliant 👏

You slayed all the Environmental“Wives Tales”. 👏👏👏

Nice shorts man. Thanks for another great video.

Fantastic summary! Thank you for such greatly composed content... 👍

Once again Simple straightforward breakdown 👏👏👌

Ta, Shane.exactly what we need to keep in mind and all well explained 👍✌🏻🌱🤘🏻

Great vid. Solid breakdown 🤘

Extremely helpful as usual thanks for all you do

Can you do a par test on the slim 650s by optic led ? Thank you keep the videos coming I really like them they’re good and always really detailed, you always cover everything about everything with what you’re covering what light fixture

Lots of excellent info! Thanks for the upload! Cheers!

Very informative Shane, thanks for your genius.

Excellent video Shane when you can simplify the complex like that it becomes philosophy. Love from HPS land IRL

Great video, great sum up!

Love everything that you do!!

This information will really help my hybrid elite genetics clone-only indoor stealth Tomato grow-op thrive.

Another amazing in depth video cheers again 😎

Thanks for the vid. Learnt a lot. Just germination of Mimosa shot looking forward to sitting back relax like✌️

Simple and to the point. My biggest bud did I just harvested yesterday had some bud rot right in the center of the biggest Cola so I cut it out I think I'm going to be okay

I really enjoy learning from you . Thank you !

Really well explained a brilliant bloke and company thanks shane

Right on Shane, as usual

Great info as always. Many thanks

His vids generell quality always 10/10

im using elevated co2 in a basement outside of the house. its not a closed system but it takes only a bit cold air from outside to climate, works great

Great videos. I just bought a grow 200 to replace an old LED fixture. I went with that over a Mars product because I'm going to need to pump a lot of moisture into the air and the Mars product scared me.

Very good video! Thank you for sharing :)

Thanks so much Shane.

Excellent info as always.

Thanks for the info!

Great vid.Chock full of important information.

Thanks for the grow tips Bro. 🤜💥🤛🌾🌾🌾

Really appreciate your knowledge and sharing it

Thank you Professor ...

Hi, names Austin, I’m looking at my plants closely everyday after work and I’ve pulled out 4 plants today and two a couple days ago because I spotted herme and male parts. I think that I might need a second opinion of these very early signs during week 2 of pre flower. From seed to current day they are 6 weeks and on 12/12 with no light leaks. I just put 2 into foam board under the pots/trays to avoid the cold from coming up into the pots. I know I’m jumping all over with this comment but I would love any info on the ventilation as well. Right now I have a 4x4x8 foot tent in flower and I have one exhaust blower directing the air outside and only have the bottom vent strip open. The humidity has been fluctuating from 50-60 % air temp is between 70-85… thanks for reading my message

Great info thank you for your time and hard work ,

Im going to need a bigger room, ive got 4 plants and ive never had much luck but this year after watching some vids,(and especially after lowering my ph, adding coco coir to soil and watering LESS ive got some monsters , i also made the mistake of putting seedlings into tiny pots till they took off but they never took off in tiny pots , once i put them into their final container they went crazy.

I learn so much from your video's!!

Such an easy explanation. Thank you sir 😎

Great job migros

Where i live, there are some "typical, annual irregularities" :) in weather patterns: a pretty oppressive high temp/humidity spell around late August, despite a lower rising sun; a brief cooler snap that precedes that late summer heat i mentioned; an early Fall high temp period that follows the first extended period of cooler Fall temps; a couple days of below avg Fall temps later, etc. I don't know that that's the rough pattern in the Tropics or Afghanistan, but i would think there are similar predictable fluctuations in any region. Have you ever considered what effects these things have? Have you ever replicated those conditions inside and compared results to a clone from the same mother grown under uniform conditions? I wonder if little bursts of stress have positive results. Thank you for the good information!

loved the video good work

Great video m8 learned a bit. cheers 👍

You are The Best Mate Good Job

Thanks Shane!

Great video as always but in my case on hot days if I run the light at night time it means the plants are sleeping during the day so then it is even hotter outside. So it does not cool down when they are sleeping.(22-24°c) This is not a good thing right? Thanks

can you do a deep dive into this? PAR VPD RH and even maybe crop steering?

Wish everyone have the chance to take a stepback. World will be Beautiful! ❤️

Excellent, thank you very much.

Great information. Thanks for sharing.

Excellent…thank you 🇨🇦

Great information Thanks. Cheers

I like a enclosed higher pressure rooms 2.5atm. Co2 around 3300ppm because the increased atmospheric pressure venting will happen once every three days. 81f 45% humidity day, 72f 60% at night for vegetative. Straight red,orange and yellow leds with multiple smaller metal halide for uv exposure .

I have been watering my plants at night when the lights are off to avoid the high humidity. Watering in the morning and then turning on the lights was causing a steam bath.

What do you think about the Luxx 645 & is the pro version better to use as a multi purpose light ?

great quality video.. nice one 😎

You talked about covering the pots to reduce the humidity in the space due to evaporation. What are you talking about exactly? Like a fully inclosed plastic lid with a hole cut for the stalk or some sort of fabric?

In my grow at night I let the temperature 21 or 21 degrees Celsius and the termometer say happy icon if yk that loook good for them what do u think.?.?.?.

I'm flowering now in a 9x4 and ha humidity is on 73% and 25c n they are n flowering ..so these are good conditions...I'm running a mars hydro fce-4800 &a tsl-2000 n mi tent.

What is the best humidity and temperature for lights off, in flower and veg. I've been running my room at 77 degrees 43%rh during flower with lights on. I turn down the temperature to 74 degrees & 50rh

I got a couple of seeds off my son as a sort of gag birthday gift, I planted 2 of the 3 and they grew, in pots in my garden till it started to get cold, we bought a tent, lights that were recommended by a friend who used to grow and have a small fan circulating the air but from there I have no idea what I'm doing, the plant has flowers on it but I don't know when it's best to cut or anything, any simple advice would be great, I have fibromyalgia so a plant that I can use would be a godsend
