You need to do more homework on CO2 systems.
Until you get everything else dialed in, and a controller, save the CO2.

Enh... Could be a little pH, a little nutrient...
Run a gallon of pH balanced water through them at the next watering. They should be good in the long run, just keep an eye on your media pH and don't feed them for a while.

Like I understand I can't be having the fans run 24/7 with Co2 because I'd just be letting all that Co2 escape through the blower, I just don't know if I should run my blower once every hour for 5 mins. then have my in line fan on for 5 mins. immediately following the blower on every hour of the day then just run Co2 for 30 seconds after that to hit 500-800 ppm, I'm just taking a good guess on that I was using the Co2 calculator to see how long it takes to get 800ppm the other day, but does that sound bout right? I know i'm in dier need of a Co2 controller just a lil strapped on cash at the moment.

CO2 grows are not budget grows.
An air conditioner is a very basic necessity for a successful CO2 supplemented harvest. If you can keep the AC unit running then you can keep your temperatures low enough to only vent occasionally. If you don't have any way to cool the room then you're going to have temperature issues, no way around it.

But I thought Co2 runs better in hotter temperatures well no more than 85-90F true? I'm running a 1 1000w on a light mover. I believe my Co2 tank is 110lb, its about 5' tall on the tank it says 110 imprinted on it so I'm guess thats what it means. But anyways, if Co2 runs more efficient in hotter temperatures then I probably would only have to run my fans say twice a day?

Yes, CO2 does run better at warmer temperatures, but you're going to cook your plants with a 1000w system that isn't properly ventilated.
Why don't you give it a try? Put a thermostat in there, turn the light on, and close the door. Come back an hour later and check what the temp is. If it's over 90 then it's too hot. If not, then ventilate the room and go another hour. If you can go 6 hours without breaking the temperature barrier then you know what you can do.
Still doesn't change the fact about the monitoring. You're not going to get your ppms dialed right without one.
At best you can try and estimate how much to use based on the volume of air in the space. You're still better off getting your environment dialed before doing CO2. The first thing any CO2 pro will tell you that you have to have everything dialed to get the real benefits of CO2.
You can do whatever you want man but, IMO, if you have to ask these questions you're not ready to do it yet. You seem to have some decent gear, so put that to use and save the CO2 until YOU understand how to use it (and could teach it) before wasting your money. The resources are available, I learned them from somewhere, and you can teach yourself too. Take the time, it's worth it.

True. I hear ya. I know I really need to get this Co2 controller, I feel like I rush myself too much and my plants are only a month old right now from seed and doing great, I got 6 strains 5 of each for a total of 30 plants feminized, but I've just been putting everything into this room and trying to create optimum growing conditions for them. I've been trying to read up on ventilation but there just doesn't seem to be that good of information out there on this topic, but does ventilation really just come down to keeping temperatures down from being too hot? and just use a regular oscillating house fan to push air around the room?
I really appreciate the info/advice man, I'll rep ya, thanks.

How long is it ok to keep a newly sprouted seedling (about 2.5" tall) under 12/12? I'm in flower right now with my first ever set of plants and don't have a separate veg space. Thanks.

Depends on the bulb. Figure if a bulb has a 20,000 hour life time then you'll want to swap it out after about 10,000 hours.
If it is a flowering bulb in use every day for 12 hours a day then you can expect about 833 days worth of use from that bulb.
If the bulb is a vegetative bulb in use for 18 hours every day then it is more like 555 days.
If the bulb only has a 10,000 hour life span, or you want to switch out after 5,000 hours, then you just cut those numbers in half.
Even 5,000 hours on a bulb at 12 hours per day you should be able to get a good 6 harvests from a single HPS lamp.

Thanks for laying down the math for me Snow Crash!! You saved me some money, I would have replaced my bulbs too soon

can you do me a favor and look over my pics and give me your opinion. that or anyone in this thread...don't want to steal but don't want to clutter.

Are LED lights a bad idea? Theyre so effecient, but if they arent good for plants then forget them.

Hey I got a question. Im using an old Phototron thats from around 1992 its very similar to http://www.youtube.com/watch?v=EEPHyWt1NYQ&feature=related but newer. When I was talking to the guy I got it from he said the buds will be about the size of your thumb. Is that correct or no?
Little question. My plants are on 24/0 veg time with cfls and plan on switching to flower tomorrow. Will be moving them to a new room (tent) and will be using an hps light. So should I start it with 12 hours of dark since it's on 24/0 or start with 12 hours of hps lighting?
Thnx!
Thnx!

Hey People
Hypothetically.......
What would happen if you had the last 3 days of flower ( Day 60-63 ) of 24 hour light ?

may stress out too much and cause it to hermie...trichs like the darkness so it really wont b practical to do that

Thanks Rasta,
But how are they going to become "hermie" in 3 days?
They cant produce seeds and pollen in 3 days......
Anyone else have an opinion either way?
