According to the U.S. Department of Energy, the recuperator is the most widely used heat recovery device. Do you have experience and expertise with the topics mentioned in this content? Tankless Water Heater Exhaust Killing Plants Never allow gases to remain inside the greenhouse. Tomato plants are very sensitive to certain pollutants found in the exhaust from fossil fuels. AC Is Killing Your Houseplants (and How Maybe there is something else going on that could be coincidental. That excellent idea of yours should be considered by tent growers.

Different species handle the effects of air conditioning differently. I am wondering if there could be another reason why the shrubs are dying. We can look at the crop and obtain air samples to verify if ethylene is the problem. Ethylene from malfunctioning greenhouse heaters may lead to crop injury. Know the symptoms and how to check greenhouse heaters to avoid the concern. The flue gases usually contain nitrogen dioxide, carbon dioxide, carbon monoxide, volatile organic compounds and particulate mater. OP was discussing CO, not CO2. 1. I had a "plume diverter kit" fitted to my vent. One of the problems is that carbon dioxide is most effective when light levels are the highest during the day and the carbon dioxide is mainly produced at night when the heater operates the most. If it is yellow or orange it needs adjustment. The 14-point pH scale of acidity runs from 0 at the far acidic end to 14 at the far alkaline, or basic, end, with pH 7 denoting a neutral solution. Check for cracks by inspecting for light penetration while the furnace is running. What is \newluafunction? Read: Why Furnace Blower Motor Is Making Noise When Starting? I'm concerned that the exhaust could harm the bush and also that the corrosive gas could tarnish the A/C. Older type technology using relay logic is not readily adaptable. But to do that, you should first be able to find them. This site is maintained by Center for Agriculture, Food and the Environment in the College of Natural Sciences. Lastly, research your plants temperature and humidity needs. Note: My experience is in the UK where terminology differs from that used in the US.
