The ETL listed Apollo 12 is the answer to your short cycle timing needs!
With a 5 second to 30 minute 'ON TIME' and 5 second to 60 minute 'OFF TIME' you can satisfy your most strict timing requirements. This timer is great for ebb and flow tables, as well as aeroponic systems. In conjunction with our CO2 Regulator, it will accommodate CO2 injection in any room configuration.
Titan Controls Apollo 12: Short Cycle Timer with Photocell Questions & Answers
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.
