The white plastic washers are replacements for the Titan CO2 Regulator (702710) or the Titan CO2 Inline Heater (702715).
Titan Controls CO2 Regulator: Replacement Plastic Washer Questions & Answers
My CO2 monitor/controller is reading really high all the time. What is wrong with it?
The main issue is the 2000 ppm of CO2 we exhale when we're breathing. If you're in your room and you see that the ppm is high, leave the area for an hour or so and turn off your CO2 source, then peek your head in and check the reading. It should be reading under 1000 ppm, depending on how well your room is sealed. After observing your CO2 Monitor/Controller for awhile, you'll start to see what your normal ppm level is in your room. The normal outdoor ppm is 400 ppm to 600 ppm based on where you live (city vs. rural).
Should I run my CO2 at night?
No, you should not. Plants photosynthesize CO2 only during the daylight hours. At night, the plants expire CO2 and have no use for CO2. Save yourself some money and only dose CO2 during daylight hours when it does the most good for the plants.
Why do gardeners enrich their growing space with CO2?
CO2 is proven to speed up a plants growth rate, improve overall health and increase a plants yield. There are also many other benefits to plants, among them greater resistance to temperature extremes and other forms of stress, better growth at low light intensities, improved root/top ratios and less injury from air pollutants.
What methods can I use to enrich CO2 in my indoor garden or greenhouse?
The two most common methods are using a CO2 generator/burner or bottled CO2. The most common generator/burner uses LP (liquid propane) gas from a tank or a NG (natural gas) conversion kit that allows you to hook up your generator/burner to the natural gas line in your house. The other option is to purchase bottled CO2 from a local supplier in your area and control its release into your garden area using a Titan Controls CO2 controller (Atlas 1) or short cycle repeat cycle timer with photocell. It should be noted that there is no advantage to increasing CO2 levels beyond 2000 PPM for most greenhouse plants. The optimum level of CO2 for plant growth is generally accepted at 1200 - 1600 PPM.
Are the Titan Controllers compatible with each other?
Yes. They are designed to work together so you may expand your system as needed.
What happens to the 'preferred settings' on my Titan Controller if I lose power?
Titan Controls digitally based equipment has 'non-volatile' memory storage that allows the unit to retain settings due to a loss of power. The analog product line settings are not affected by a loss of power and will maintain dial settings.
