co2 tank questions

Hydrokronics said:

Im pretty sure this is the best place to ask for the help that i need regarding co2. you seem to be very knowledgable Drama and i a wondering if you could help me? I just purchased a 10Lber and a hydrofarm regulator kit. The distribution tube didnt have any pre drilled holes in it and i am not sure what to do. The instructions didnt say anything, about doing anything to the distribution tube. I need to know how large to make the holes and how far apart to space them. I want to make sure i get this right because i dont want that to be the reason that the co2 doesnt run efficently. I know the holes should be very small but im hoping you have some expirience with the subject and/or could tell me how your distribution tube is set-up. Thank you for your time!

I have my distribution line wrapped around my entire plant area. I keep the line about 6 inches lower than the tops of the leaves.
When making holes in the line, I used a drywall screw and poked holes in it every six inches.

My setup is pretty easy. First of all my tubing is above the plants, no holes in the tubing it just ends right in front of my intake fan. It is timed to release a 5PSI stream every 6 minutes for about 10 seconds. the intake fan spreads that out and it slowly starts to sink as it is carried along the canopy to the other side where it will be exhausted out after a trip all the way across the grow area. A 50 pound tank lasts a total of 16-18 weeks of flowering in my smaller grow space ( 2 square meters). and CO2 levels are kept between 1500-1600 during the entire lights on period.

Basically I am using a fan to disperse the CO2 over a wide area, you could poke holes i guess but i don't see it as really necessary.

true. Thank you for the idea. would u know a good settng to set it at or how i would go about setting up a hydrofarm reg that way?

what controllers would you guys recommend, and lets say money at the time is an issue, whats the most affordable means of getting the extra co2 to your plants.

i mean i can afford the tank, guages, and tubing, anything else thats cheap that i would need. or would i just open the tank manually for a couple minutes and then shut it off (with fans off ) and is it best during day time in the room?

would i just shoot co2 all around my plants or just let it leak inside the flower room for a couple minutes probably from above since co2 is heavier right? of course i could do this with out being in their so i dont get poisoned but how much time would i need to give it before its safe for me to go in.

If you read the thread all your questions are pretty much answered.

is there any large chain stores that fill co2?

Praxair is a large co that refills, they are everywhere it seems.

Perfect. found one like 20 min from me. Not trying to suck anyones cock, but i dont think i have had a question yet that drama didnt have a full answer to. thanks again fro all you help.

I was wondering though if you could hlep me with my scheduling. I am curious how i should set my timer. I have a .2-2 regulator and am not sure how many times a day for how long i should run her. another issue is that my setup is in a closet type senario, so i will be pumping in there but it is open to the enitre room which is about 10x10. so i am assuming since the smaler "closet" type area is not sealed, the co2 will need to be adjusted to fill the entire room to efficent levels. I would just seal the smaller room but then would have heat issues. and Since the co2 will be inicially coming from that area i would assume it would be more beneficial there. Thanks again for your help and so for the long winded question.

Currently I'm using the ole' sugar and yeast co2 production but plan to upgrade to a tank and valve asap. So, my question is how big of a co2 tank do I need for a 6x6 room?

how high is it? 10'? if so then a 50 pound tank should last a whole grow. if the height is restricted you may be able to get away with a 20 pound.

But CO2 is heavier then air, so height shouldn't matter.

(yes, I'm just being a wiseass. Shitty day.)

ok so i know this is someone elses thread but i need help.when i crank my tank co2 comes from the know instead of my regulator.im confused please someone help.
