11 . The method according to claim 1 , wherein injecting the at least one treatment, gas, or substance into the sealed enclosure includes injecting gas into the sealed enclosure, the gas including compressed, filtered, dry, or humidified air, industrial gas, ozone, air, or any combination thereof.
12 . The method according to claim 11 , wherein the gas includes industrial gas, the industrial gas including nitrogen, carbon dioxide, carbon monoxide, an industrial gas that has been ionized or treated by plasma or corona discharge, or any combination thereof.
13 . The method according to claim 1 , wherein injecting the at least one treatment, gas, or substance into the sealed enclosure includes injecting gas into the sealed enclosure, the gas comprising functional substances mixed into the gas, the functional substances including one or more forms of: chlorine dioxide, nitrous oxide, hydrogen peroxide, peracetic acid, ozone, or any sanitizer, ionized air, ionized industrial gas, ionized sanitizer, ionized water and/or pH adjusted water or pH adjusted sanitizer, limonene, lemon oil, orange oil, grapefruit oil, rosemary oil, thyme oil, sunflower oil, other fruit-derived oils, tea tree oil, cinnamon oil, eucalyptus oil, potassium oleate, sodium dodecyl sulfate (SDS), ascorbic acid, citric acid, sodium bicarbonate, potassium carbonate, calcium phosphate, linear terpenes, cyclic terpenes, alcohols, aldehydes, esters, ketones, lactones, thiols, lipase, rose oil, rose essence, and fruit essence, vitamins, minerals, flavonoids, flavor compounds, color compounds, essence, essential oil, sugar, THC or THC compounds, CBD or CBD compounds, probiotics, phages, enzymes, pharmaceutical compounds, biological compounds, or ripening agents such as ethylene.
