Defoliation and CO2

I'm on day 24 in flower, did some defoliation during the vegetative period and a quite heavy defoliation on day 22. I'll do some light defoliation if necessary up until around day 45 and then I'll defoliate heavy again. I have CO2 tank, but it only lasts ~2 days and I can only afford to refill it once, so I'll add extra CO2 for 4-5 days
When is the best time to do this?
Everything else is dialed in and looking good.

Thanks in advance.

If you just run co2 for a week or so, it like eating 1x a week for yourself and nothing else. Total waste of money and co2.

You don't need CO2 without any leaves, as you plant can't use it, but beyond that, lets say you didnt defoliate, CO2 is a waste unless you seal your room
*and*
your lighting/nutrients reflect the need for it.

I recommend saving it until you possess the proper knowledge, and save yourself some money.

One more thing, hope you have extremely stable genetics to be defoliating once in flower, especially that late into it. I forsee a stressed out plant throwing many nanners.

It's a 170fl oz tank with a regulator and a controller with a built-in photocell that automatically activates the unit only during the day, will run it at 1000-1200ppm. The tent is 10'x10'x6,6 and it's as sealed as it can get.
This is not my first grow, and like I said everything is dialed in and looking good. I'm just extremely limited for how long I can run CO2 this time and want to make to most of the little time I got.
My first time with defoliation though and the plants have responded well during the grow.
As far as I know the whole plant uses photosynthesis, not just the leafs. They are not stripped totally naked, there are leafs left, but I would consider them to be quite heavy defoliated.

Leaves are like solar panels. No leaves, the plant is unable to utilize photosynthesis. How would a tree or plant use photosynthesis with out the leaves to absorb the light?

Might as well as ray Charles to drive you to the store. With it crashing. And a tent can never be sealed. Take a peak with light on inside, dark outside the tent. See all those light leaks, those will now be co2 leaks. Plus a 170oz tank won't last but 1 to 2 days at 1200, even 1000ppm.

It what do we all know. I only been growing for 4+yrs, 2+ with co2 and sealed dialed in bang out harvests every run after run after run.

But merry christmas. Didn't mean to be a grin chaos on your going parade.

If you are looking to get the most out of CO2, it is best utilized at a higher temp and in Veg. 83 degrees seems to be the ticket in my eyes. In flower, I drop temps and CO2. Try to seal the room the the tent is in? A well sheetrocked room will get you much further. I wouldn't recommend it for safety but you could try wrapping the outside of your tent in poly and tape it with Sheathing tape (tuck tape). The shit will peel your fingerprints, so I wouldn't expect to get it off anything you stick it to though (ie. your tent).


Best bet is to get everything dialed in and then build a room THEN get CO2. Otherwise you are just wasting money with little gain.

What lights are you running?

Just because you can dig a 10ft hole with a spoon, doesn't make it the tool for the job.

Plants require leaves to survive, and fruit well. You want larger yield? ..then stop doing what those shwazzing bullshitters say while taking advantage of the noobs @$500 a pop, and learn REAL science behind how plants work.

Leaves are required in many areas of the plant beyond photosynthesis, for instance, the number one reason "transpiration" works is because the stoma, located within the leaf. Do you like the fact that your plant uptakes nutrients? That's mostly because of leaves. Where do you think the plant exchanges CO2 and O2? The last thing you need is having your cannabis plant do photorespiration.

Plant respiration happens in the mitochondria of each plant cell. Half of the plants respiration occurs under the soil.

Thx, but I'm aware of how plants work. With the lack of stomata & leaves, CO2 level 'will' be low and photorespiration will occur.

Lol, CO2 requires leaves to work there bud...

Thats like going to the hospital, hooking up an oxygen tank via face mask to a guy with no lungs...

Dont remove any leaves unless they have nicrosis.

If you have a perfectly healthy plant whose leaves undergo senescence, it's in your best interest (and hers), if you "leaf" them be ("typo" intended). :bigjoint:

if ur growing out doors yes leave ur leaves on but indoor is a different story .. sure u can leave em on but its not as good as taking em off .. defoliating is the way to grow indoor for sure... .. lol dont believe me ,i suggest doing more research on this topic.

A plant is a plant, nothing changes if moved inside. Transpiration, photosynthesis, osmosis, and cell devision all work the same..

Maybe you should do some research yourself, and not just from hippies or empirical observation or social conformity, but real science..

ur the one getting advise from an outdoor old school hippie bro lol fuck jorge cervantez lol.. ill make it easy for u to learn buddy . go to growweedeasy.com and search defoliating lol proof is in the pudding ... see that pic i got on my pro thats what defoliating does for u .wanna see the harvest vids,pics. i got proof .what do u have?

I didn't learn what I know from jorge, "bro". I posted jorge because simply because some people do. I personally learnt by college, and attending lectures.

Growweedeasy is filled to the brim with pseudoscience.
