The Importance of Air Conditioning in Maintaining the Quality of Flowers at Hiatt’s Florist

Introduction to Hiatt’s Florist

Hiatt’s Florist is a family-owned flower shop located in the heart of downtown that has been serving our community for over 50 years. Known for their creative floral arrangements, vast selection of flowers, and exceptional customer service, Hiatt’s Florist is a staple in our city.

The shop first opened its doors in 1965 when husband and wife duo, Frank and Betty Hiatt, decided to turn their shared passion for flowers into a business. What started as a small flower stall expanded into a full-fledged storefront on Main Street by 1970. Today, Hiatt’s Florist is run by the couple’s daughter, Susan Hiatt-Thomas, who prides herself on continuing her parent’s legacy.

With over five decades of experience working with flowers, Hiatt’s Florist understands that properly caring for their floral inventory is essential. One of the key factors in maintaining fresh, long-lasting flowers is controlling the temperature through air conditioning. Read on to learn why air conditioning is vital for a florist shop like Hiatt’s.

The Importance of Temperature in Flower Preservation

Flowers are living organisms that continue respiring even after they are cut from the plant. Part of this biological process generates heat, which speeds up the flower’s life cycle. Additionally, exposure to hot external temperatures causes flowers to transpire at a quicker rate, resulting in wilting and deterioration.

For these reasons, regulating temperature is critical in floristry for preserving flowers. Most flowers require an optimal temperature between 35-40°F to slow down their respiration and prolong their shelf life. Tropical varieties, like orchids, prefer slightly warmer temperatures around 55°F.

Without cooling methods, the 10-day lifespan of typical cut flowers could be reduced to just 2-3 days. Air conditioning allows florists tomaintain the ideal climate conditions for keeping flowers fresh as long as possible. Proper temperature control can double or even triple the vase life of many popular blooms.

Understanding Air Conditioning: A Brief Overview

Before examining its role in floristry, let’s review the basic principles behind air conditioning. Air conditioning systems work by leveraging chemistry and physics to lower air temperatures.

The core components of an AC unit include:

  • Evaporator coil – Absorbs heat from indoor air
  • Condenser coil – Releases heat to outdoor air
  • Compressor – Circulates refrigerant between coils
  • Expansion valve – Allows refrigerant to expand and cool
  • Refrigerant – Chemical that changes from gas to liquid

By cycling refrigerant between gas and liquid states, an AC unit is able to transfer heat energy and provide cooled air. Modern AC systems also have the ability to control humidity levels by removing moisture from the air.

The Role of Air Conditioning in Floristry

For floral shops, air conditioning is essential for preserving inventory and maintaining profitability. The optimized temperatures and humidity levels created by AC units allow cut flowers to remain in peak condition for as long as possible. This extends the shelf life of floral arrangements and reduces spoilage due to wilting.

Proper air conditioning also creates a comfortable environment for customers and employees. The chilled air keeps florist shop interiors pleasant even during the hottest days of summer. Adjustable AC settings allow flower shops to fine-tune temperatures based on the products they sell and seasonal weather changes.

How Heat Affects the Quality of Flowers

Exposure to heat negatively impacts cut flowers in several key ways:

  • Increased respiration – Higher temperatures accelerate the flower’s biological processes, using up nutrients faster. This causes premature wilting.
  • Faster transpiration – Heat causes flowers to lose water rapidly through their leaves and petals. Dessication and drooping occurs.
  • Impaired development – For unopened buds, excess heat can prevent proper bloom development, resulting in visual defects.
  • Discoloration – Many flowers will experience color changes, fading, or browning when subjected to hot temperatures.
  • Bent stems/neck – The weakened state of heat-stressed stems makes them prone to bending at the neck or midway point.
  • Accelerated senescence – Warmth hastens the aging and death of flower cells, shortening overall vase life.
  • Botrytis infection – Heat stressed flowers are more susceptible to fungal diseases like Botrytis or powdery mildew.

These cumulative effects severely impact decorative aspects like appearance, fragrance, and longevity – reducing a flower’s desirability and salability.

The Science Behind Flower Preservation

To understand why temperature control is so critical for flowers, it helps to look at the science behind how cut flowers stay alive.

After being cut, flowers enter a period of stress as they are no longer attached to the nurturing parent plant. Nonetheless, the cells in each flower part – petals, leaves, stems, and buds – remain biologically active.

Through the process of respiration, flowers continue to undergo metabolic functions to survive, drawing on stored energy reserves. This includes:

  • Breaking down sugars to fuel cell processes
  • Reacting sugars with oxygen to generate ATP energy
  • Releasing water vapor and carbon dioxide as byproducts

These respiratory processes produce heat. That’s why freshly cut flowers feel warm to the touch. Under cool conditions, respiration is slower, conserving a flower’s finite energy. But exposure to heat accelerates respiration, draining resources.

Flowers also lose moisture through transpiration. Warm conditions cause flowers to transpire faster than their stems can uptake water. This depleted water content leads to wilting, shriveling and drooping.

By keeping flowers cool, their metabolic activity slows, and transpiration reduces, allowing them to maintain visual appeal and last longer.

The Impact of Air Conditioning on Flower Longevity

Research has quantified the dramatic differences air conditioning makes on the vase life of various popular cut flowers:

  • Roses – Stored at 36°F, roses lasted 16 days, compared to 4 days without AC.
  • Tulips – Pre-cooled tulips had 11-15 day vase lives, while uncooled tulips only lasted 4-5 days.
  • Gerbera daisies – Cooled stems remained visually appealing for 7 days versus just 2-3 days on uncooled flowers.
  • Lilies – Lasted up to 2 weeks with AC, but wilted within 4 days without temperature control.
  • Iris – Preserved for 8 days with AC compared to 4 days without.
  • Orchids – Cooled phalaenopsis orchids bloomed for 6 weeks rather than 3 weeks.
  • Chrysanthemums – Display life extended from 7 days to 21 days with AC cooling.

Clearly, air conditioning provides a dramatic boost to the usable shelf life of many popular floral varieties. For perishable flowers, AC is a lifesaving preservation tool.

Case Study: Hiatt’s Florist’s Approach to Flower Preservation

At their main downtown store and wedding venue, the entire Hiatt’s Florist operation is climate controlled to protect their floral inventory. Susan Hiatt-Thomas was gracious enough to provide a tour and outline their air conditioning strategies:

  • Central AC system – Multi-zone HVAC system allows for temperature adjustments in different areas.
  • Backup AC unit – An extra AC unit provides redundancy in case of primary system failure.
  • Coolers – Walk-in floral coolers with humidifiers keep stems hydrated.
  • Refrigeration – Commercial-grade flower refrigerators for sensitive varieties.
  • Monitoring – They check temps daily to ensure optimal flower conditions.
  • Maintenance – Quarterly HVAC maintenance helps prevent issues.
  • Employee training – Staff are taught proper AC system use to prevent flower loss.

Their layered approach provides complete climate protection for the diverse array of floral products they handle.

The Benefits of Air Conditioning for Different Types of Flowers

While all flowers need proper temperature control, certain flower types benefit even more from air conditioning:

  • Tropical varieties – Orchids, anthurium, heliconia require cool 55-65°F temperatures and high humidity levels. AC systems provide these conditions.
  • Sensitive flowers – Delicate blooms like lilies, tulips, and carnations wilt quickly without sufficient cooling.
  • Out-of-season flowers – Air freighted blooms accustomed to cool chain supply lines are especially heat sensitive.
  • Closed buds – Unopened buds of snapdragons, amaryllis, iris require cooler temps for proper development.
  • Miniature flowers – Extra cooling helps prolong the short vase life of mini carnations and gerbera daisies.
  • Expensive blooms – For costly flowers like gardenias, AC provides protection for the investment.

With strategic temperature adjustments, air conditioning caters to diverse floral needs under one roof.

Air Conditioning Settings for Optimal Flower Preservation

To maximize the postharvest life of their flowers, Hiatt’s Florist adheres to these ideal AC temperature ranges:

  • Main shop floor – Kept between 62-68°F for customer comfort while preventing flower wilting.
  • Flower coolers – Set to 36-38°F, the optimal temperature for most cut flowers.
  • Tropical cooler – Humidity controlled unit provides 55-60°F temperatures suited for sensitive orchids and anthurium.
  • Prep room/back office – Ambient temperatures of 60-65°F prevent flower damage during processing and arrangements.
  • Flower refrigerator – Extra sensitive flowers like lilies are chilled at 40°F to prolong vase life.
  • Delivery vehicles – AC maintains cool chain as flowers are transported.

Precise temperature zones maximize storage times for the diverse flowers they handle.

The Role of Humidity in Flower Quality

In addition to cooling, regulating humidity levels is also crucial for cut flowers. The vast majority of blooms naturally grow in humid environments and cannot draw moisture through dry air. Low humidity causes rapid water loss through transpiration.

The ideal relative humidity level for cut flowers is around 95-100%. This saturates the air with moisture, preventing flowers from drying out.

Air conditioning systems remove humidity, so floral coolers must have specialized humidifiers to restore moisture balance. Misting flower stems also provides added hydration. Proper humidity complements temperature control for complete flower care.

How Air Conditioning Helps Control Humidity Levels

Air conditioning units are designed to reduce humidity through a process called dehumidification.

As air passes over the AC unit’s cold evaporator coils, water vapor condenses and moisture precipitates out. This removes humidity from the circulating air.

While dehumidification is desirable for human comfort, excessively dry air will damage flowers. That’s why commercial floral coolers have humidifiers built in to add moisture back into the air after it is dehumidified by the AC system.

Maintaining optimum temperature and humidity levels together is vital for preventing flower dehydration. Air conditioning combined with proper humidification provides cut flowers an ideal microclimate.

The Connection Between Air Quality and Flower Health

Beyond temperature and humidity control, air conditioning also impacts the longevity of cut flowers by affecting air quality.

Flowers are sensitive to the following air pollutants which can accumulate in florist shops:

  • Ethylene – Given off by fruits and ripening plants, ethylene hastens flower aging.
  • Formaldehyde – Released from foam, adhesives, and disinfectants, which irritates flowers.
  • Benzene/Toluene – Emitted by synthetic materials, paints, and plastics causing flower damage.
  • Ozone – Formed by pollutants reacting with sunlight; oxidizes and injures plant cells.
  • Molds and fungi – Airborne spores spread fungal diseases like botrytis to stressed plants.

By venting stale air and circulating fresh air, air conditioning dilutes contaminants that could shorten flower life. Cooler AC temperatures also deter fungal or bacterial growth.

How Air Conditioning Improves Air Quality in Florist Shops

The air filtering abilities of AC systems provide cleaner, safer air for delicate floral products:

  • Ventilation – Exhausts remove internal air pollutants and introduce fresh outdoor air.
  • Filtration – Pleated filters trap dust, pollen and airborne particles that stress flowers.
  • Air circulation – Fans and blowers prevent localized pockets of contaminants from forming.
  • Temperature control – Colder conditions deter ethylene production and pathogenic fungal growth.
  • Humidification – Added moisture prevents dehydration even in filtered air.
  • Pressure differential – Positive air pressureinside shop repels pollutants, allergens, and pests.

With AC systems, the air surrounding flowers is kept continuously clean and breathable.
