I just put in a co2 unit. One of those green air products. I have it in my flower room. Flower room is approximatly 150-200 square feet. I have it set on a timer with my lights 12/12 cycle. The unit comes on 4 times throughout the lights on period for 30 minutes each time. Totalling 2 hours of co2 production per night. The pilot light is always burning on it also. Is this enough? To much? I use 1/2 hour segments because thats what my timer is set up for. i can go get another if need be. At what stages should I be using the co2? I have heard to only use it at the first 3 weeks of flowering to avoid cannaibanoid detereration. What temps are the best suited for using co2? My room is completly controlled and I can range from 46F' to 120 F' at any given time. I spent a ton of money on climate controlers but having the control is worth it. So yea, I can set a temp and keep it there or relativly close. Please shoot some advice this way. Mean? This is your area if I am correct...Shitttt, Every area is your area, lol. Thanks guys...
You will want to achieve 1500 ppm per cycle,20 minutes is a long cycle,more ten minute cycles would be better.You need to take the cubic ft ( L x W X H ), multiply the rooms cubic ft by .0012 and this will give you the required amount of ppm to get to 1500 ppm based on the typical air in a room which averages 300ppm telling you that a increase of 1200ppm is neccesary to achieve optimum benefits.Which model do you have,CD-3,6 or what and i could tell you the time needed to achieve this and I need the cubic ft of the room,not the sq ft. Keep in mind that at 1500 ppm the plants will be unstressed at up to 95 degrees while still maximizing the co2.Dont waste the co2 with fans/exhaust fans running on high while releasing.At the minimum turn down circulation fans low.keep in mind the heat of the room will increase with the use ofa co2 generator as well and that is why it is better to lesson the cycle time it takes to get to 1500.Maintain a 73-77 temp as usual,this will also lengthen the time it will take the co2 generator to start increasing room ambient temperature.get me that info and I can tell ya the time neccesary to achieve 1500ppm.
Medicinal,dont forget the model # for which generator you are using.Pm me your msn messenger address as well so we can do some catching up.
Mean, I have a cd-6. The room is 8 x 12 x 9 = 864 cubic feet I think, lol. And I run a control wizard box that takes care of the temp and Humidity. Intake and exaust run together and when they come on, they automaticly turn off the CO2. Neat little gadget for $87. We are into winter up here and it gets pretty chilly at night. The exaust fans do not really come on much. I have 2 1000 Watt HPS lamps going and it keeps it warm. I also have a large box fan I keep on low, and a little oscillating fan for the tops of the ladies. Thanks for your help Mean G.
So maybe a dozen times during the 12/12 lights on period at say 10 minutes each interval would be sufficiant correct?
Exactly,freshen up the flower room one time per hr.You are going to like the results.Keep inmind if ya get a bug prob ya can temporarily krank up the ppms with a longer cycle,thus a increase in ppms and kill the bastards off.Peace
Ha Ha Ha, Now that ya mention it, Got a few of SATANS little bastards in there right now. i will crank her up a bit. Been using the cold temps lately to keep em down. But the CO2 sounds like it will hurt em a little more. Heh Heh Heh.
I remember reading an article in a science journal on the capabilities of plants (in general) to utilize excess CO2 in the presence of light. Something about calculating the optimum lumens to ppm CO2 ratio, as plants can only utilize excessive amounts of CO2 up to a point that is dictated by avilable light. I'll look for it.
Glad to see you Geck. And thanks Mean. Good Points mentioned. I have a new timer in the flowering room and set it to hit 15 minutes on every hour. So 45 minutes off, then 15 on every hour. I have 2 1000 Watt hps lights with large round parabolic hoods hanging side by side. This creates a serious amount of lights where they intersect on the sides. The ladies sit on a table that is about a foot off of the ground, 7 foot wide, by say 4 foot across. I will add pics asap. Anyhooooooo, The CO2 is doing great. I have monstor buds that I never knew were possible. I am getting the chance to see my plants genetics at an all time high.... Thanks guys. And PICS ASAP.
