what bottles?? the bottles im thinkin of that seems like big $ and risky when u go to fill it back up. i think the bucket will do good in a 6x6x6 room. have the fan on for 15 min every 2 + hours or so..

I am about to buy my CO2 equipment but one thing is confusing me:

Flow meter setting or generator size in CFH (Cubic Feet per Hour)

What is this? what is a standard setting I could use to get an idea (I just want to run some figures so I get an idea which size tank to buy for my grow space)

Well we used all of the math to try and get the CO2 right, bought the testing kit (was $34 + $5 per test) and thought we were pretty ontrack. I am an electrician and of course looking for ways to automate as much as possible. Went on Ebay, found a seller that was selling CO2 sensor/control for $230.00 BEST money we spent. Wish we would have saved the original $84 we spent on the syringe test kit!! The sensor is SIMPLE, and FAST and ACCURATE!! We have our room sealed very well, and are amazed that 15 minutes or so of a person in the room will raise the CO2 level by about 300 PPM. Our CO2 comsumption has gone down, and we now have a consistant level. The sensor I found even has software available so I can monitor the CO2 level OUTSIDE of the room!

So all in all, my opinion is, if you really want to use CO2, think seriously about looking for an electronic control as well. BTW, dont waste your money on the controls that claim to have FUZZY logic for the level. Our CO2 level never varies more or less than 50 PPM and it is a standard control. The fuzzy logic controls I have seen START at almost $500 and go up as high as you want to spend.

Again... just MHO

for my room i calcultaed that .5 at 15 min is the best but I am running 1 and the results are awesome. it is about 3000 ppm at least and I do it and exhaust it every two hours. i am loving it set at 1 and at .5 I see no results. odd but I may have a lot of air leaks. i measured it with a syringe. For my flower tent I have a selenoid by cap of course and for my tent i just have a tank so far and I measured that one blast is like 4000 ppm! lol. but that is not sealed really yet and i do it once or twice a day. Plants love co2 in veg. I swear it is beautiful.

For those of you who dont know spend the extra bucks or as I did get it for the same price as the hydrofarm model. I mean by the cap model of solenoid. the hydrofarm one is crap and freezes up. That is why they say dont use a controller. But the cap is ok.

Same ideal behind people using steroids. They can still play sports really good, they just put up better numbers while doing steroids.

i was thinking the same thing till you realize that using 2 buckets which is over $200 is close to the same price to buy and own a 20lb tank with a regulator.

im confused. lol so many suggestions. can someone break it down and explain the system they are using what size tank or burner and how much does it cost them to refill the tank or how much propane or natural gas they use up.
