Starting and running a greenhouse business can be an extremely rewarding and profitable venture. The global greenhouse horticulture market continues to expand rapidly, reaching a value of $28.3 billion in 2022 and projected to rise to $48.3 billion by 2028, exhibiting robust 9.2% growth year-over-year according to recent research by IMARC Group.
With demand for fresh, locally grown fruits, vegetables, flowers, and herbs continuing to rise, a greenhouse operation can be a viable full-time business or profitable side hustle for entrepreneurs and gardeners alike.
However, launching a profitable greenhouse business takes careful planning, preparation, and hard work. This comprehensive guide provides aspiring greenhouse entrepreneurs and growers with a complete overview of the critical steps and considerations for starting a successful and lucrative business.
Carefully research and select the ideal greenhouse structure, size, and crops to maximize profits and suit your goals, land, and climate.
Create a comprehensive business plan detailing costs, revenues, operations, marketing, and financing. This is the roadmap for success.
Obtain all required licenses, permits, and insurance before launching your greenhouse venture to stay legally compliant.
Choose a site with ample sunlight, utility access, convenience, and proper drainage and wind protection.
Implement savvy marketing tactics like niche crops, diverse sales channels, and branding to profitably sell your greenhouse harvest.
The first major decision that new greenhouse business owners face is identifying the type of greenhouse operation they want to build. Carefully considering your goals, resources, property, target market and more can help determine the ideal greenhouse style, size, and crops for your new venture.
There are several types of greenhouse structures, each with their own advantages and drawbacks:
Gable – The most common and versatile greenhouse style with a peaked roof shape, providing excellent structural stability and light penetration. Gable greenhouses are available in a variety of sizes.
Hoop House – An inexpensive, low-profile option constructed from PVC piping or metal framing covered with plastic sheeting. Hoop houses provide less temperature regulation but can be easily built.
Geodesic Dome – A dome-shaped greenhouse with triangular panels made from plastic or glass set within a network of metal struts. Geodesic domes have excellent strength and utilize space efficiently.
Glass Greenhouse – Glass panels allow maximum light transmission but have higher startup costs. Aluminum framing resists corrosion in glass greenhouses.
Plastic Greenhouse – Plastic film or rigid acrylic panels are an affordable covering option. Plastic is less durable than glass but easier to install.
The size of your greenhouse will depend on factors like budget, property space, crop output goals, and heating and ventilation requirements. Options include:
Hobby Greenhouse – Typically 100 sq ft or less, suited for backyard gardeners wanting to start seedlings or grow a few specialty crops.
Small Commercial Greenhouse – Around 1,000 sq ft, an affordable stepping stone to larger operations, allowing diverse crop cultivation.
Large Commercial Greenhouse – 5,000+ sq ft growing spaces to support major wholesale crop production. Require greater investment and land.
Select greenhouse crops based on profitability, your growing expertise, resource availability, and local market demand:
Vegetables – Greens, tomatoes, peppers, and cucumbers are common valuable greenhouse vegetables.
Herbs – Basil, cilantro, parsley, and mint offer year-round harvest potential.
Flowers – Orchids, tulips, poinsettias, snapdragons, and more for bouquets or ornamental use.
Mushrooms – High-value specialty crops that thrive in greenhouse humidity and warmth.
The ideal greenhouse climate maximizes plant growth and depends on the crops grown:
Heating – Supplemental heating extends growing seasons. Popular options are hot water pipes, and electric or gas furnaces.
Cooling – Ventilation, shade cloths, misting systems, and air conditioners can provide summer cooling.
Lighting – Supplemental lighting like LEDs can optimize light levels for photosynthesis during darker months.
Irrigation – Drip irrigation, misters, and hand-watering are common greenhouse watering methods.
After deciding on the greenhouse type and crops, the next crucial step is creating a detailed greenhouse business plan. This plan will act as an invaluable roadmap that outlines every aspect of your new enterprise.
Startup costs for a small hobby greenhouse can total around $5,000-$12,000 including the structure, equipment, and supplies.
For a commercial greenhouse business, total startup costs often range from $60,000 to over $200,000 depending on the size and features.
Ongoing operating expenses like labor, utilities, maintenance, and crop inputs average around $20,000-50,000 annually for a small commercial greenhouse.
A breakdown of typical startup costs for a commercial greenhouse is shown below:
| Item | Estimated Cost |
|---|---|
| Greenhouse Structure | $15,000-$100,000 |
| Heating and Cooling Systems | $5,000-$15,000 |
| Irrigation System | $2,000-$5,000 |
| Seeds and Transplants | $500-$2,000 |
