When I want to exhale co2, I think it is necessary to stop the air extractor ... how long should these periods last?
it's safe hold disabled air extractor during day-time for about 4 hours per Co2 Session?

@GreenCooker it should be fine to shut off the exhaust just keep an eye on temperature as it could jump significantly if no air is being exchanged.
During late flowering DO NOT shut off your exhaust as you will need all of the air movement and exchange you can achieve to mitigate any chance of
bud rot forming due to excess moisture inside the tent

Iam using a CO2 extractor from TNB, filled with sugar, yeast and lukewarm water. I use it in my growbox. The growbox has a exhaust too. I just let it run , because Co2 is heavier than O2 if hang down the bottle the co2 is sinking down in your growspace. Iam sure to see the effects of CO2 with arunnig exhaust

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!2 months ago

Remove leaves from auto?Should I remove fan leaves from my auto flower? I wonder since it is so crowded, I worry a bit that the leaves are pressing against the buds. But maybe that isn't a problem? I've read that removing leaves is unnecessary and stressful for the plant.

So many leaves! Should I defoliate even more?I defoliated just before and even during the first week of flowering, but she keeps growing so many leaves even during the second week of flowering.
Should I defoliate right now or wait a couple of weeks? I worry I could halt the flowering or cause even more useless stress...

Excessive nodes and autoflowersMy plants have SO SO many nodes. In my opinion they have way way too many branches. Is there anything at all I could do as far as cutting/pinching, some of them off? They’re autoflowers and I’ve only really found people saying don’t do it.
