WHAT IS RELATIVE HUMIDITY? 💧 Every Deck & Engine examiner asks this - don't get confused! 👉 RELATIVE HUMIDITY (RH): It's the percentage (%) of water vapour ACTUALLY present in the air compared to the MAXIMUM amount the air can hold at that same temperature. Formula: RH = (Actual Vapour / Max Capacity) x 100% If RH = 100% = Air is fully saturated = Fog, dew, sweat will form! If RH = 50% = Air holds only half of what it can hold. Why is it critical at sea? FOR DECK: High RH = Cargo sweat & ship

You can absolutely grow many plants in your relative humidity of your home or with very little humidity in general. Some plants are need that extra humidity but if you’re looking to increase humidity for longer than a few seconds, ditch those pebble trays and the daily misting.
