As long as you wish. 75 degrees is a safe temperature to store ammo in. Low humidity makes for good conditions to store ammo in.
75 degrees F OK that's fine for temperature but what is the ideal room humidity percentage? Actually, most building codes only require you at keep the temperature at 68 degrees, which is ideal. The ideal room humidity percentage is usually around 50% ASHRAE Standards: 68-74F @40-60% relative humidity in the Winter 73-79F @40-60% relative humidity in the Summer
The ideal indoor humidity level according to the humidity chart in Fahrenheit is around 30-50.
The usual design humidity for an indoor swimming pool is 50% RH when unoccupied and 60% RH when occupied Peter Fenton. Consulatant. Indoor-Pool-Design.com

Indoor humidity levels are typically controlled by heating, ventilation, and air conditioning systems, while outdoor humidity levels are influenced by weather conditions such as temperature, precipitation, and wind. Indoor humidity levels are usually more stable and can be adjusted with the use of humidifiers or dehumidifiers, while outdoor humidity levels can fluctuate throughout the day and night.
The indoor humidity in winter should ideally be between 30-50 to maintain a comfortable and healthy environment.
Indoor humidity is typically calculated using a device called a hygrometer, which measures the amount of water vapor in the air. Factors such as temperature, ventilation, and sources of moisture like cooking or bathing are taken into consideration when determining indoor humidity levels.
Indoor humidity is typically lower than outdoor humidity because of factors such as air conditioning, heating systems, and better insulation in buildings. These factors can remove moisture from the air, leading to lower humidity levels indoors compared to outdoors.
The most popular indoor temperature is 72 degrees.
With an indoor pool (not a spa) room air temperature should be maintained 2-5 degrees above the water temperature< with 50% or less humidity.
The recommended indoor humidity levels during winter are between 30-50 to maintain a comfortable and healthy environment.
An indoor fruit tree nursey would be hard to control. Most homes do not have a high enough humidity level to sustain their growth. You would need to add humidity to a room, and keep the door closed. Most fruit trees do require a cold snap of several hundred hours below 40 degrees to grow properly.
