There will be a limit where the CO2 is depleted and the plants will be smothered with O2. In certain situations, the extractor will need to maintain a negative pressure on the enclosure for scents.

can't i'm afraid ..how fast does it (Go down)i gathered you know? ..high light is a relative term, can you be more specific? How fast does it (go down)?, in what temps? does rh% have something to do with it one way or another?
EDIT: i mistakenly wrote 'rises' at first when i was supposed to ask about co2 going down
My tents aren't totally shut when bloom lights are on
I usually have the tent door flapping open abit and having the circ fan on alll the time there is some "passive" ventilation. So my tent isn't totally sealed.
It's something to think abut for sure

It comes back up instantly with air circulation. My room will go from 1400ppm to under ambient in well under 90 minutes if the co2 is off.
Co2 is something you want to remain static with the lights on. If the levels fluctuate, the plants usually adapt to the lowest level quickly.
CO2 is carbon dioxide, the stuff animals exhale.
In a space that isn't ventilated, plants will use up the available store and then stop growing because it's a necessary basic nutrient. If you're in with the plants or if there's decent fresh air circulation, they'll get plenty.
The other option is active supplementation. Don't bother with CO2 grow bags; they don't produce enough.

People get all caught up in NPK but plants are over 95% carbon, oxygen, and hydrogen by mass.
That's good to know. i have to look into it more ..on very rare occasions m y tent is fully closed when lights are on but it's something to think about for sure
Had some sort of brain malfunction yesterday.
..i should have asked how fast co2 goes down instead i wrote how fast it 'rises'.
Funny how you're sometimes blind to your mistakes and the next day these will clearly pop out and you wonder what was i thinking when i wrote that! ha ha

I followed him too. Heck even bhougt acess to his forum and got his seeds. Remember a friend trying his bud once, gave him 2 nugs of the kool Aud stuff, he got popped cause of the k9 sniffing him out on railway station, but they let him go
RM3 did a lot of funny experiments.
Is he still in the game and doin his PLL grow?

As my exhaust vent fan is moving too much air to have it on full time when lights are on, as rh% and temps go down with it
I’m gonna put a short piece of 125mm plastic pipe attached to the exhaust fan and drill holes in to that pipe to tune down that suction a little bit
Few 10-12mm holes or as many as is needed to get the air movement just right
And then some filter cloth on top of that to keep the dust out
This way i might be able to run it the whole time lights are on and then use a timer to have it go on every now and then as lights are off

Do you have a suggestion for one for the hobby?

AC Infinity makes one IIRC. I’m using their controller right now, it works well via Bluetooth to an old phone with no service.
I heard LED needs more magnesium?
Obviously a bullshit narrative from Big Epsom. Common theme on all the fucked up crops I consult is 5x the magnesium needed.
If Cannabis growers sent their leaves in after harvest, we would have stopped calling everything "uneedum calmag" and "light too bright makum leaf taco" long ago.

If people would just go 1 run with nothing but base nutes they’d see how bad they’re fucking their plants up at the same time they’re wasting money on products they don’t need.
i think u are rite... i am 14days into 12/12, at about 3 weeks in veg i gave em a tiny amount of cal/mag... didn't seem to hurt the plants, but did a ressie water change some days ago, n didn't add any, plants look fine...

Have you cultivated those genetics before?
The first time around it wouldn’t hurt to run light on nutrients to see which, if any, nutrients it wants more or less of based on your feed.
I’m using three different salt blends, each of them will be high in nitrogen, potassium or phosphorus. Calcium and magnesium can be supplemented if needed based on leaf mutations.
Be aware, anything labeled “for cannabis” will have a higher price than anything “off the shelf”. If you know what you are looking for you can get lots of nutrients for basically nothing. For instance, the nutrient package I am using cost me $40 and I’m not sure how long it will take me to use all of that salt, it will be a while.
Cheers!
i have not grown these seeds b4- i check on em every morning and late afternoon - one is a sdkush and it could occupy the whole 5x5ft tent, its that wide... and it drinks almost 2gallons of water a day.. i am keeping the nute level (general hydro 3 part) at between 800-1000, and the ph stays pretty much . around 6. the others a headbanger,runtz muffin and a purple punch , are much smaller and drink way less- those also have a ph in the high 5's, to low 6's and feed similarly... 14days into 12/12 and they look fine... can't get the temp much over 74/75F, and the humidity is around 60/65, which i will have to bring down .. i have a 50pint humidifier which i will set up in the coming days... this is my 2nd rodeo with hydro... the 1st one last year was ok.... but who is looking for just ok....
The switch from HID to LED typically reduces transpiration because the plants are getting less infrared. This does affect the nutrient mix needed.
What are you using? Link?
That'sa good way to burn out the fan by making it work against a load it wasn't made for.
You might consider running it on a timer, 15 on and 15 off. Or get a smaller fan. Or, depending on the fan, a speed controller. (Some fans can work ok with them, others need a VARIAC and those are too expensive).
