co2

[ph0neman]

hey folks just out of curiosity... i am thinking of using the co2 setup discussed here with the yeast/sugar and bottle...

when should i start using this in my grow room? i currently have the seedlings on an 18/6 cycle and some are at two nodes some are three.

should I wait until they start to veg a little more or wait until they go to flower?

basically is there any benefit to use this method when they are so small?

thanks for any information.

Well, there's no way it's going to hurt them. You'll probably get two possible results here:

1) No spectacular increase in growth with the C02 at this stage

or

2) Accelerated growth, because of the C02

No matter what stage the plants are in... as soon as they have leaves they're photosyntheizing, thus needing C02 to make their energy and mass. So, my guess is that there will be a small positive result... because there's not much leaves at this point I'm not sure if you'll notice it that much, but go ahead and do it up!

Good luck!

^^^^ thats like saying... Theres 2 answers!

1. There is a god

2. Theres not....


It means nothing... Basically ph0neman. I would start using it. It can only help. And since putting a bottle in my room, the plants look more healthy and my little ones have DEFINATELY picked up since. Just keep an eye on the bottle in the room so it doesnt fizz up and spill ect.

Hey man... I'm just saying there that would be only positive effects, if any. And I was explaining that the plants need leaves to photosyntheize, and use that CO2. So with few leaves, it would probably have a small effect.

I Disagree. Just cuz a baby is small, doesnt mean it doesnt need oxygen.

so there's no fresh air available in your grow area? co2 isn't a magic bullet for plants. not meaning to sound like a richard or anything. supplemental co2 isn't even beneficial unless you are running temps. above what, 82 degrees?? now you're talking about a sealed room for the most part. when i'm growing, i try to keep temps. in the mid 70's. i can accomplish this fairly easy with a strategically placed fan or two. i have probs. keeping rh up. unless you're in a situation where your plants have no access to fresh air, "and" your temps. are in the proper range, don't waste your time and money on co2.

[ph0neman]

just for the record i didn't say there wasn't fresh air and i am not looking for a magic bullet i was just asking if it would beneficial. The plants are growing as expected so far just seeing if I added a little co2 would they appreciate it.

so growbot you are saying co2 isn't utilized by the plants under 82 degrees?

thanks for your responses


info:

the room stays between 72-75 during the light cycle and approx 77 when the lights are out (i open the furnace vent at night so they dont get too cold) <-- if i didnt the temps go to 57 or so

thanks again for responding.

and you didn't sound like a richard i appreciate your input

didn't mean to offend. yes, if you've got fresh air and your temps. are in the range you mentioned then you won't benefit from co2. think of it like adding more air into a room you're in. unless there's a shortage it isn't necessary. again, didn't mean to sound richardish...

[ph0neman]

haha no offense taken thanks for clarifying... appreciate you taking the time to respond

I'm not experienced enough to know from experience, but in my growers bible he says co2 enhancement is beneficial as long as you use HIDs. It is a waste with anything less. He didn't mention temps, that I remember, but like I said, I'm not experienced enough to know from experience, just a little more imput.

every time i've used co2, i've seen a substantial jump in growth. for the cost of maintaining the co2 "jug" it's well worth it.

[ph0neman]

i dont know if i can tie the growth to the co2 but i just checked my babies and they show substantial improvements overt the last two days... could be entirely coincidental not sure but i have had the bottle in there for two days and it seems to helping

thanks for to those that have responded, all feedback helps when making an informed decision

the mechanics of using co2 can easily be looked up on any search engine. grow bibles are good to use as guides. it's also hard to tie growth to co2 when it could easily be something else. people see what they want to see in their plants sometimes. it's hard to say that co2 didn't help when you're in for a couple hundred dollars. the only way the stomata are going to open additionally is with higher temps. unless they open farther they aren't able to take in the additional co2, it's that simple and it's simple plant mechanics.
