cool thats good to know thanks,i had plans of running co2 at night cuz i dont have to run exhuast as much,but now i wont lol
so are you saying if your above 10,000 lumes with floros you could still benifit from co2? i got 12,000 lumes in a large upright freezer could add 3,000 more mabye
also do you think air coming in from a basment would have enough co2 in it,not
to even bother with adding more?
thanks man ,peace
At night plants actually release some of the Co2 absorbed during the day. This is why I run a closed system with my flower room exhausting into my veg room. While flower room is dark, veg room is still illuminated for 6 hours and receives released Co2 without running my tank system. Though the veg room is smaller, vegging plants can endure higher levels of humidity, and the veg room has its own exhaust set at a higher humidty level. The veg room exhaust into a room with a dehumidifier (portable a/c in Summer) from which the flower room receives intake. I swear by the closed system for its efficiency and enhanced stealth.
Peace
P.S. even the water from the dehumidifier or a/c can be recycled into you reservoir without using R/O.
Ambient air is still around 300 ppm period.Quote:

I guess that's why I am a control freak with my plants.
Here is a caculator that may help you

Is there a signicant difference between bottled CO2 and a CO2 generator? How do they compare efficiency, safety and cost wise? i do know that a 5 gallon tank of propane on a CO2 generator will last 3 times longer than a 20 gallon bottle of CO2. not sure what it cost for 20 gallons of CO2?
thnx, bill
The propane or gas version is cheep to operate compared to tanks. They do have a down side and that's heat. They burn several flames to make CO² but they do it on the cheep. Tank does cost more money the large ones last a few months and cost about 40 bucks to fill. Tanks do not have the heat problem and that's always a positive thing to not add heat. You only run CO² during light hours so the heat is at max anyway. Unless you have a very large AC system it's hard to run natural or propane gas to make CO². The warmer temperature could cause the plant to turn hermie so watch out for temperatures above 88F.
BBBBBBBBBBBBBBUUUUUUUUMMMMMMMMMMPPPPPPP :)
I had a discusion with the owner of a local paintball store being that when I used to first play, I was using Co2 as my propellent, though now I use HPA (High Pressure Air). Theres many fittings you can get threw mail for the tanks and it can release a slow stream. Like a 20oz tank can last about a week and a half slowly leaking out, and refills are like 5$-7$... Though my plants are "Orchids"..
I was thinking being liquid Co2 turning to its gasous form is fairly cold, I was gonan try to have the air enter the plants grow closet right where my HPS bulb is...
i have heard that spraying your plants with soda water is helpful for co2... has anyone tried or heard of it??? am sure it wont harm the plants anyway.. might give it a go!
Here is a snippet from my "Super-boost for plants" thread:
This works perfectly well with any type of lighting from my observation, using CFL myself and using extra co2 dramatically increases growth and health of plants. Regarding smell, it does not really give off much smell if you do it as described and only use small tiny holes in the caps to let the gas out, and keep all fairly sealed (which I assume it is in an in-door setup in either case)Quote:
3. Create extra carbondioxide (CO2) for your plants. This alone can boost the growth and make them twice as fast growing.
Simply take several bottles, or larger container of your choice, and add 1 cup sugar to every 2 liters warm water along with 1 spoon yeast. I personally recommand adding some cut up / blended fruits as well such as apples, grapes, oranges, as this procedure will produce alcohol and with fruits in you will get some wine as an additional bonus.
Once ingredients are mixed (remember using warm water) in your bottle / container of choice, put a lid on tightly and pin a small hole in the lid. The hole will release the CO2 gasses and is a MUST even if you just want to make wine and not use the gasses for the plants, as without the hole the bottle WILL explode and you will have a mess. The hole should be about needle sized, so using a needle to pin a hole is fine.
Now place these bottles or containers with the lids with their holes around your plants. A suggestion is to connect a hose to the top lid and leading the hose into the plant area so you can have larger containers & bottles in a different nearby location.
This will ferment and create CO2 for 1-2 weeks. After 2 weeks max you should take the contents of the bottles and change and do the same procedure to create more CO2. If you want to save the alcohol / wine you make by this carefully siphon out the liquid leaving a small part with the yeast solids and fruit parts at bottom. You may need to filter it first to discard fruit solids, and then let it sit for a while to make the yeast solids sink back to the bottom before siphoning off.
If you want good instructions on making wine or other alcohol simply google "brewing wine" , "brewing beer", "brewing alcohol" etc and you can use any recipe you find just make sure to lead the releasing gas to your plants.
These bottles or containers should be shaken once or twice a day - remember holding a finger on the hole in the lid when doing this or it will get splashy.
The bottles or containers should NOT be filled completely, leave about 1/5th space empty as it will foam and bubble during fermentation and you dont want that spilling out.
