co2

[green the great]

Hi Guys and Gals,

Can someone please shed some light on the topic of co2?

Is the sugar and yeast poured on the soil - what do you do with it? - very new to indoor growing here as you can see? I feel stupid asking if it is poured on the soil - or is out in front of fan to circulate.

No explanations in FAQ.

My indoor grow is in a big bedroom with partially opened window - lots of air circulates as the grow box is not enclosed. I have one cfl of 23watts on each plant - only two plants in total.

They are growing great under 24 hrs light with these conditions. I am getting a new set of leaves every one - two days approx.

Do i need co2?

I have a fanblowing on them only for about one hour a day due to it being in a large room with open window - any advice here?

your gonna need more than 23watts per plant!!!

more like 50 watts at LEAST

 

[k-town]

oh and you put the sugar and yeast in a 20 oz. soda bottle with it HALF filled with warm water and puncture a hole in the lid and shake every so often for first 24 hrs. to start reaction and after that every time you want a burst of c02 just shake it and set by your plant(right underneath co2 rises)

cover hole when shaking w/ thumb

when the shit is fizzling or bubbling that's the co2 being given off!

peace out hoped that helped

tyr do it yourself for better instructions just go to bottom of this page to FORUM JUMP and scroll to DO IT YOURSELF and boo yah there ya go

Thanks Ktown - i got it.

I will add more cfls when i need them - but if the plants are growing daily isn;t that enough - even though they are 23 watts its equivalent to 150 watts - they are energy savers - lumens are 6400?

 

[k-town]

don't even pay attention to the equivalent watts you need the watts to add up to at least 50 watts per plant but during seedling and sprout you should be fine but I am also gonna use CFL's and plan on LST(low stress training) my two plants and am gonna have about 100 watts per plant

the more light the better

better yield(more weed)
better quality
faster growing

I mean it may be possible to use 23 watt but you PROBABLY be dissappointed

ok thanks k town

CO2 is heavier than air and sinks to ground

A couple of quick comments:

Lightining:

You want more light so they do not stretch. You want them to fill out nice and bushy. This will require more than 2 23w CFLs for 2 plants. For example, I use 10 26w 6500K CFLs in my seed/veg box. In addition I have 5 18w floros.

CO2:

Most suggest CO2 during flowering. I am not sure if it is worth the pain for veg. I use CO2 during flowering and it does have a positive impact. In my case I use a paintball CO2 tank with regulator and flow control.

My 42w CFLs are pushing around 2800 lumens each, so I doubt your 23w CFLs are pushing 6400. More like 1200 or so. Don't quote me on the 1200 lumens, just a guess. Best thing to do (if not eluded to on the package) is to visit the manufacturer's website and look up your bulb. Should tell you everything you want to know about it. At least GE's website did for me.

Since we're on the topic (not trying to hijack though)...

If you veg on a 18/6 schedule, would it be better to use co2 during the dark period? Same question for flowering.

CO2 is only useful during lights on, it is used for photosynthesis. And it is heavier than air, so it will sink to the floor. Leak it above your plants.

Here's my standard advice: Don't worry about CO2 until you have everything else operating in your growroom. Simply provide plenty of fresh air. And grow a couple of crops without it, get all of the bugs out of your system, and then add the CO2. That way, you'll be able to see if it makes any difference. When adding CO2, your plants will use more of everything else, more water, and nutes, so you should have more light. All factors combine to grow a healthy plant.
