That is a calculator you may find helpful.
thanks for that ZANDOR....
another question.
can i put a mh bulb in my sodium ballast if its the same wattage?
that site doesnt work Zandor?
It just worked when I tried it again. :(
I just ran one of my rooms 7 x7x7 it said
Grow room area: 343 cubic feet
Amount of CO2 required: 0.6174 cubic feet
On time: 9.26 minutes
At this flow rate:
If you are using a 20 pound CO2 bottle with a regulator, it will last 43.7 hours.
If you have a CO2 Generator a 5 gallon propane tank will last 135 hours
that is correct, 1800PPM at a rate of 4CFH for my tank CO²
Sorry if it did not work for you.
thats has helped,thanks bro

i have a small co2 cylinder that holds 2kgs of gas,with no fittings,so how will i work out at what speed will let the right amount out?
You need to get the regulator and timmer then. Should cost between 75.00 and 140.00 bucks usd. You can get them on eBay for cheep. You use that to regulate the flow and timer to turn the flow off and on. You just caculate how long it needs to run.Quote:
