Gonna try using CO2 - What ppm should it be set to?

My buddy had a co2 setup he donated so was going to try and get that going tonight.

It comes set default of 1500ppm.

I've got a 4' x 4' grow tent. Two plants...although one is a behemoth and the other is living quietly much smaller. Not sure if the number of plants matters.

Is that the information required to determine proper ppm?
 
Got up off my a$$ and looked through the documentation like I should have originally.

Co2 Calculations:
1. Measure and multiply: length x width x height of your grow room to calculate the volume of cubic feet
2. Generally, the c02 level in a grow room is 300 ppm. To bring your room to an optimum level of 1 500 ppm, you will need to raise the c02 by 1 200 ppm.
3. Multiply your room volume by 0.0012 (1 200 ppm = 0.0012) to determine how much c02 to add to your grow room.
EXAMPLE: a 10' x 8' x 10' room:
1. Volume= L x W x H
volume= 10 x 8 x 10 = 800 cubic feet
2. 800 cubic feet x 0.0012 =.96 cubic feet-- you can round this to 1 cubic foot. You will therefore need to add 1 cubic foot of c02 to a 10 x 8 x 10 grow room to bring the c02 level to 1 500 ppm.


So it sounds as if I don't need to worry? I just set the meter to 1500 and it'll take care of the level of CO2. Easy Peasy? Wish me luck.

You got it dialed in correct phatz06. my 4x4 is working well on a self regulated 1500 ppm monitor that controls the electronic regulator. Just plug it all in and seal it up....and keep an eye on humidity based on your growth stage (mid/late stage flower shouldn't venture over 50%)
