Why Control CO2 Levels at Night in Plant Grow Rooms?

Why Control CO2 Levels at Night in Plant Grow Rooms?

Author: Michael Forster, PhD, Edaphic Scientific  Growers can artificially increase the amount of atmospheric carbon dioxide (CO2) available to plants to improve growth and yield. But at night, plants do not uptake CO2 for photosynthesis. Maintaining artificially high levels of CO2 at night may, therefore, be wasteful. Low cost technology is now available to automatically switch on and off the CO2 gas supply during the day and night. In this article, we outline 5 reasons why you may consider turning off the CO2 supply at night via your CO2 monitor and controller. 1. Decrease CO2 Costs Turning off CO2 supply...

CO2 in Aerobic, Anaerobic Composting

Composting is a common method for organic waste disposal. In composting, micro-organisms convert waste into useful products like fertilizer. There are 2 kinds of composting: aerobic (with air) and anaerobic (without air). Although both break down organic matter, aerobic composting depends on micro-organisms that get oxygen from the air, whereas anaerobic composting depends on micro-organisms that get oxygen directly from the waste matter. Aerobic Composting The advantages of composting is that it naturally kills pathogens like E. coli, converts ammonia nitrogen to organic nitrogen and reduces the waste volume. The disadvantages of composting are the loss of some nutrients including...

Constant CO2 Level in Greenhouse

  Controlled CO2 gas inflow and improved air mixture can help maintain optimum CO2 levels in small indoor greenhouses or grow rooms. These were the lessons learned after working with a client who was attempting to control the CO2 levels in a group of 3 10x20” greenhouses. The client wanted to maintain different consistent CO2 levels in each greenhouse to test the effects on the plants inside. To control the CO2, he used our iSense 1% CO2 Level Controller, a more industrial version of our Day Night CO2 Monitor & Controller for Greenhouses. In one test greenhouse, the CO2 controller...
