Excellent information! I have to watch it at 3/4 speed to retain it all!

Your five minute training blocks are loaded with quality information; and they are fun to watch-cheers from Tempe, AZ.!

Always a pleasure and looking forward to your DIY CO2 video: )

i really enjoy your videos, very well done and informative! 👍

seriously thanks for your videos man, good info and entertaining too.

Homebrewing and indoor gardens go together so well! 😜

Just found my new favorite youtube channel. Excellent quality vids. Very well done.

love the video,thank you for the helpful info,

2 Big videos I've been really looking forward to since I found your awesome channel; Carbon Dioxide 102 (hopefully including information on closed rooms) and, a big one, RO Water vs Distilled Water. Love the Channel Everest. Thank you

Awesome and informative as usual. Thanks!!

2nd room! I can't wait!

Thank you for the information you are constant reliable source

Regarding hydroponics in a greenhouse, would you recommend a fan installation just under the eaves of the roof? Fans would be parallel level, but in opposite corners, one to blow in, one to blow out.

You are so great thank you

Ur delivery is top calibre

I have a little co2 paint ball tank and I just let some out the take into my grow tent like 3 times a week

I might have missed something but what /is any thing vary with the growth cycles ? Because of the hassle is any particular time best for the co2 addition other than lites on ?

does it matter what the PPM levels are in the night cycle even if my Atlas 8 reads it to be negative? (- 1450)

Nice video. Neato

I have a under grow room 6 ft × 10 ft 7 ft deep. and I got 2 1000w HID lamps going.and it stays at about 75 F° in the day and will drop 6°. All I us to cool it is 2 fans and a intake of the air from outside ( the lights are cooled )

Always awesome. Id subscribe twice if i could. Hey, some diy tips would be fantastic. Ive experimented with the yeast/sugar, and have been successful half the time. I dont have the recipe right.

u r the best of best teacher on this matters,u r awesome,,ur materials ,informations ,u r alive wikipedia on hydroponic

Hi Everest, new subscriber here. Thanks for the great vids. Do sealed rooms with co2 enrichment need to be vented more than just at night? I'm getting alot of conflicting info. Some say vent fresh air every couple hours. Some say never vent fresh air (which I don't agree with). Thanks!!!

Building a basement sealed room with ac dehumidifier and co2 would like not to vent at all can I drop co2 levels at night to mimic natural conditions

I love how you speed up your videos...

THANKYOU!

Hi Everest! Please I want some help of you, can you help me to calculate how much last a 20 lbs co2 tank for a 3*3*8 feet indoor garden? The lights will be on 12 hs per day and the co2 PPM that i want to reach is 1200. Thank you very much.

Is the root system absorbing CO2 also would increasing carbon dioxide to hydroponic root system have any benefits? Thanks for your time...

If i use a humidifier do i still need to ventilate my growrom.

What are considered sub-optimal conditions? It’s hard to find any information about the role of frequent or constant venting for greenhouses with regards to CO2 enrichment.

Your voice is superb dude....

I can turn my air off in a co2 controlled room?

Looks like this is an old video, but I hope I still get a response :P What are those (what looks like) rockwool cubes on sticks in the plants at the back around the 2:00 mark for?

I use 1800 ppm do fresh air exchange every two hours

Hey Everest. What kind of par meter is that?

do you run co2 all the way in flower?

What about extraction fans? Wouldnt they take the extra co2 out???

What would I said the flow meter at in a 6 x 9 room

Can’t you put the generator outside the grow room and pump it in to cut down on heat .

I wonder if anyone has grown anything under pressure like in two or three times the atmosphere

Hola volví a instalar mi grow en una zona caliente . Voy a usar AC y co2 .. acá estoy aprendiendo de nuevo

Cheapest ppm meter on the market and where to get it? Any way to test for 0-9999 ppm cheap?

Can I use dry ice?

oh and maybe more info on features of different co2 controllers. lots of them regulate co2 until the lights turn off via photo cell and if you don't purge you'll have co2 in your garden all night. maybe a video on controllers/machines working together to control environment.

Hi Everest, First I would like to thank you for all of your videos. You have been the only person on KZfaq with consistently accurate info on indoor hydroponics. I have a bit of experience and went through all your videos to see how your content compares to my personal experience and this is literally the only thing I have found questionable. So I've never seen plants turn yellow with co2 enrichment at night. It was my understanding that the stomata close off and do not absorb co2 with lights off so it would be wasteful to use it. Can you explain how you reached this conclusion or cite your source so I can look into it further? I would like to implement this if there has been decent research behind it. Thanks and keep up the awesome content! If you ever need ideas or someone to bounce them off feel free to contact me. Austen

You should do a video on all the co2 alternatives

What about small scale grows, like 8x4x10?, burners seem like overkill. Super informitive and love the humor!

How long does a co2 bottle last?

One has to wonder: back 450,000,000 years when the CO2 level was 7000 ppm, who turned on the exhaust fan when the lights went off. Seriously though, in nature the CO2 level during the day would be the same or less than at night, wouldn't it?

you have a god-like ability to spit out all things i need to know in the shortest amount of time possible. you know your audience: we don't have time to listen to you breathe!

Get video btw got a question for you. So if I'm using the co2 bags/buckets set my extraction to come on and off at 15 min intervals ??

Audio is low. Loved your video. Thanks.

I am using some Arduino's and eCO2 sensors so report and plot CO2 levels in my grow rooms. This is great except that these CO2 sensors are not very robust. Do you recommend any other CO2 meters that can log levels to a computer? Thanks

For 102 - PAR, Temperature, and other targets for CO2 added? I know you can handle more heat and I'm assuming more light too.

Is there a Carbon Dioxide 102 yet? I’m ready for it?

I love your channel and it does help with many things but I gotta say, a lot of this is apparently meant for people who have A LOT of extra money lying around. I mean, $400 here, $350 there, $450 there... that is so much money for just a few extra gadgets. Isnt there any cheaper models of some of these things that can be recommended for their functionality and accuracy??

My tomatoes are green and smell really skunky idk what I did wrong

I do home brewing as well as Hydroponics... believe it or not I got a 20-pound tank (big) For carbonating soda and beer... refills for the tank or only 6 bucks.... check out fire extinguisher refill places

If I have a sealed room with air conditioning co2 supplement is a must have?

@ 4:30 you would benefit from putting a sheet of plastic around the base of the 'Net Frame' (whatever you call it) to confine the falling CO2 with the Plants (for a few minutes longer, before it spills out or is wafted away). Only a _tiny_ improvement, but only a _tiny_ cost and effort; IF you have excessive amounts of Reflective Plastic you _could_ use that, but the benefits of the more expensive plastic vs. the few Photons it would redirect at that distance is far less than the benefit of the cheaper clear plastic (and it's durability) in the _particular_ situation shown in that particular Setup at 4:30. Usually you will want the Room 'sealed' and let the hot air _float_ over a Partition to an adjoining Room where the AIR only is vented, the HEAVY CO2 remains _trapped_ (mostly) in the first Room (since it is too heavy to float over the Partition). A CO2 Meter in the 'Air only Room' shows how much CO2 you are wasting by letting it spill over into the 'Air only Room' from the 'Plant Grow Room'. You can still do other things in the 'Air only Room', even grow, just with minimal CO2. Gotta be BOTH cheap AND generous with the CO2, anyway you can do both at the same time is a BONUS, otherwise just waste SOME (small) amount of CO2 since its cheaper than more Lights (which are barely efficient if the CO2 is at normal levels. DO NOT Vent for the first hour or two (watch out for the Temperature) to maximize CO2 saturation while the Room is cold (from the Lights being off at _night_). IF you're breading for Seeds (or course you are) then don't be afraid to get CO2 up to 2K in a HOT and OVERLIT Room, as that _tells_ the next generation that LOTS of CO2 is available (and to go all Prehistoric on you). First few generations should be slick, shiny, rubbery, thick Leaves; that means you're punishing the Plants with CO2, subsequent generations will show less of those effects as the Plants adapt to brutal conditions (and grow like Weeds). Great Video, again. Like shoving your Lights as close as possible on a LightRail you need to drown in CO2 as best you can, you ALSO NEED Plants that can take it. Adding a bit of Sucrose or Iron-rich Molasses to your water helps too (and is both less effective and less expensive).

It's been 4 years i still want 102.

Hi Everest How much increase in yield does CO2 supplement provide ?

some info on vpd would be cool. great video.

Amazing videos as always. Just curious what light is that in the back ground? Kind of looks like a Hybrid of DE/LED combo...

So it basically cost over 1000$ to supercharge your grow room with co2

Ventilated grow room.........How could I run ventilation & co2 in alternate 15 min cycles through the light on period. What type of control would I need? would a titan Kronus 4 & Atlas 1 do the job? I want to run exhaust and intake fans 24/7 on a titan mercury 3 or something similar. thanks for your time

Did you ever get around to doing a video covering DIY co2 generation, Carbon Dioxide 102?

I suspect these numbers are exaggerated despite the idea being basically true. Where the 1700 number comes from I would like to know. Much past 1200 seem like the point of diminishing returns although this may vary from plant to plant.

How can you vent out in a SEALED grow room?

Do you use co2 in you non sealed rooms?

Everest For my 10x11 foot sealed room 8 foot ceiling my plan is to run about 1200ppm filled room you said in your video that we should dose when lights are on. When the light turn off and with the room being sealed how would you you get rid of the high PPM? Note I am not pulling air from outside or exhausting

hah, nice reference to c3 grasses ;)

Hello Everest, Great information as usual. I subscribed and am watching your videos at 3 AM. So... The propane burners obviously create CO2 in your grow room. My understanding is that they also must create carbon monoxide which is toxic. If they create, say 1500 ppm CO2, they must create also some high doses of carbon monoxide. Or... am I missing something?

Why the rockwool cube on the sticks?

Can CO2 grow without AC in Bay Area?

Another great video, as always! I do wonder though, ideal CO2 levels would depend on the amount of micromoles the plants are receiving, right? Are there instances in which CO2 does not aid in photosynthesis because the plants aren't receiving enough light? If so, do you have an idea of where this threshold lies?

Use cryo tanks instead of scuba cylinders, last a lot longer, you see them outside of Burger King Mcdonald for their CO2

Hm interesting info Everest! I heard from MANY people (local grow stores and just about everyone with a opinion on the internet) that the water yeast and sugar method doesnt work at all, or in better terms it doesnt create enough co2 to supply a room... Is there any truth to that Everest? Or have I been tricked and spent a ton of money that would have been better used somewhere else! Also another method I've thought about that isnt too safe but would work is candles around the grow room correct? Not the safest but candles do produce a ton of co2 from my experience and are DIRT, DIRT, DIRT, cheap. Not that I'm advising anyone to use a open flame that isnt properly contained lol. NEED YOUR WISE WORDS EVEREST!

what up with the 102 tho

102 plz

awsome video. as usual. how can i contact u ?

yet to have co2 enrichmentment add any bennefit that i didnt have to pay for with gear and gasses. waste of time, yes i got slight increase, but with costs of gas i paid for it dollar for dollar, if not more since a oz only costs me 15 to grow, id need many oz more to pay off and be worth it, and it doesnt.

TY India :], so nice you are making america green again :D MAGA

That's right, plants thrived back in the day with CO2 levels of 7000ppm. Of course back then the world was vented at night so the plants didn't suffer.

😀😀😀

Humans existed 20 million years ago maybe not in the exact form we are now but we definitely existed

I thought that plants take up co2 during there dark cycles

Them damn exhale bags are straight snake oil! I’ve tried them and actually have a co2 ppm meter to see if they work and they maybe raised my ppm 50ppm witch isn’t even half a breath from somebody. All these videos show ppm using them but never show a actual ppm reading. I run co2 tanks for my grows.

Millions and millions and millions and billions of years ago( 7,000 years give or take a few) God created carbon dioxide

What's up bro? Was that you at 2:00 ? U don't look like u sound 😅👍

That co2 controller is junk trollmaster is where its at

Don't buy off titan controls and if you do make sure it's the right part need. returning shit there is a nightmare .gonna take 30 days to get my money back

Playing it pretty fast and lose with the term "101"

build it faster man I wanna see that video lol do it do it do it

👍✌️✌️✌️👍👍👍👍👍

One has to wonder what exactly is going on in the heads of those who are dedicated to the preservation &/or replacing the natural world while being rabidly dedicated to reducing CO2 to the point of crippling the development of industry & society as a whole. Obviously the reality & understanding that the vegetative aspect of nature i.e trees, plants, grasses, forests, etc, etc, which happens to be the foundation necessary for the existence of a multitude of other lifeforms (including humans Doh!!!), requires & benefits greatly from CO2.....is no longer present in the minds of many. Probably squeezed out by the numerous false realities & misunderstandings that fill many minds today, commonly based on emotional stimuli as opposed to actual knowledge. "Aaargh! Increasing populations means the world won't be able feed everyone....the only solution is MUST REDUCE CO2!!!" Well yes, naturally, as the present CO2 level will aid in creating an abundance of vegetative growth & explosive crop production.....and that's just terrible. Check this....not one single eco-friendly or pro-nature organisation, so called, has or will address the issue of the annual spraying of hundreds of thousands of particulates into the atmosphere consisting mainly of metals aluminium, barium, etc that have been ongoing for over a decade....that has resulted in pristine snowfall on mountains, that just over a decade ago was melted by hikers for drinking water, to today containing levels of aluminium 60,000 (sixty thousand) times than that of the FDA stated safe amount and is also causing &/or significantly contributing to a drop in soil PH levels around the planet resulting in widespread die off of vegetation unable to live in such acidic conditions... ...but don't panic as Monsanto has created a genetically engineered strain of wheat highly resistant to high aluminium levels. I mean, what are the chances....isn't coincidence just an amazing thing. ROLL UP! ROLL UP! COMING TO THE SKIES NEAR YOU! LOOK UP & WATCH IN REAL TIME THE DELIBERATE COLLAPSE OF EARTH'S ECO-SYSTEM! P.S - But don't say or do anything about it or you might be called a conspiracy theorist 🤫

I just open a window i admit ;)

Where’s 102, I’m building my own controller from an Arduino. Make a video!!! Come on buddy!

Newbies should be careful with CO2 in unventilated spaces. Every year there is someone who kills their family by running a generator or car in an unventilated garage and it displaces too much oxygen in their home. So be sure to use some sort of regulator.

I know this vid is old and you are...in hiding? But hopefully you take time to riddle me this. What about adding CO2 to your nutrient water?
