OG is worldwide community so I’d like to ask which problem is more common among our members. Cooling or heating?
POLL: Most of the time I need to …
- I need to COOL my cabinet
- I need to HEAT my cabinet
Where I live we’ve got pretty much both problems… Most of the year (3/4) conditions are very cold and we need to heat to avoid damaging plants by freezing or stuck growth. Ideal is to switch night and day so that lamps heat the room during (outside) cold night. During lights off there is no such difference in temperature between outside and target inside temp so grower can save on heating.
For heating usually electric heaters are used only during period when lights are off. Another solution is to suck in air from living areas which is pre-heated. When lights are on it is also preferable to reuse the air and vent it into the living area. Because of smell this is only possible when using separate air circuit for lamp.
As pretty much ideal and universal solution is heat recovery ventilation (HRV) which can supply fresh air exchange. It can bring dried air into the room while not losing much heat energy. It also helps to reduce hummidity indoors and offer better climate control. This is in my eyes ultimate solution for saving electricity costs.
In general during 1/4 of the year (June, July and August) there is predominantly need for cooling in my area. Again partly this problem is solved by switching day and night and having lights turned on during (colder) night. Due to high purchase costs growers try to avoid Air Condition systems and rather build over-size ventilation system (which is regulated by choking it up during cold months).
Those who take into growroom pre-heated air from living areas are hit with in summer big with this problem. Solutions include having separate air circuit for cooling the lights (using cooltubes and other air-cooled hoods) and another for cooling grow area. This way heated air from lamps is extracted quickly out of the room.
What is your take on these problems?
