A few things matter most for student safety. Polycarbonate covering rather than glass is the standard recommendation for schools — it's impact-resistant and doesn't shatter, which removes the biggest hazard glass would introduce. Wide doorways and clear circulation paths keep the space navigable for groups of students moving through at once. Sturdy benching at appropriate working heights keeps students working safely and comfortably. And the structure itself is engineered to local snow and wind loads, so it holds up to whatever your climate brings. When you configure a school greenhouse with us, these aren't upgrades you have to know to ask for — they're the defaults for institutional projects.

Most school greenhouses require stamped engineering drawings — drawings reviewed and stamped by an engineer licensed in your state — and some jurisdictions have additional review processes for buildings where students will be present. Some of our structure series can be engineered to meet these requirements; others can't, which is why knowing your requirements early helps you choose the right structure from the start. The most useful first step is asking your local building authority what they require for your specific project. Once you know, your sales rep can guide you toward the series that fits. We've spent 80 years navigating institutional code requirements, so this is familiar territory.

More than most schools realize, and the funding environment for school greenhouse projects is unusually strong right now. Federal programs include USDA Farm to School grants, Perkins V career and technical education funding, and NRCS EQIP for high tunnels. Many states run their own Farm to School and school garden programs. Private foundations fund these projects too — the American Honda Foundation, CHS Classroom Grants, and Whole Kids Foundation among them. Many school projects combine more than one source: a grant covers the structure, a CTE budget covers equipment, a foundation grant covers the rest. The funding programs section on this page lists specifics with links.

The widely used standard is about 60 square feet of greenhouse area per student, with roughly 30 square feet of bench space per student. For a typical class of 20 to 30 students, that points to somewhere in the range of 1,200 to 1,800 square feet for most high school programs. But there's an important distinction worth thinking through first: are you building a class-only greenhouse focused on instruction, or a production-focused greenhouse where students also grow at meaningful scale for sales, a CSA, or community programs? Production-focused programs need more space than the per-student standard suggests. The educational level guide on this page breaks down typical sizes and budgets by program type, and your rep can help you size for your specific situation.

Schools use their greenhouses across three levels. The first is curriculum — plant science, STEM, FFA and horticulture programs, farm-to-table education, career and technical education, and special education programs all run through the greenhouse. The second is community — open houses, plant sales, partnerships with senior centers and libraries, field trips, and public events that turn the greenhouse into a visible school asset. The third is revenue and partnerships — some programs rent bench space to local growers, supply restaurants, run CSA programs, or attract sponsorships that help sustain the program financially. The greenhouse is rarely just a classroom; the strongest programs use it across all three.

Year-round use comes down to equipment, and what your climate requires. For cold-season use, unit heaters keep the greenhouse in its growing range through winter. For hot weather, ventilation and evaporative cooling manage summer heat. The equipment you select determines how far into each season your program can operate. If year-round programming matters to your curriculum, that's worth designing for from the start rather than adding later. Summer use is also where the community and production side of many programs lives, since students are out but the growing continues.

Greenhouse equipment needs routine upkeep to perform reliably — keeping evaporative cooling pads clean, checking fan motors, replacing covering as it ages over time, and checking structural connections. None of it is complex, but it does need to happen consistently. The teacher-turnover question is a real one for schools, and the practical answer is documentation: keeping basic operating and maintenance notes with the greenhouse rather than only in one teacher's head means a program survives a staffing change. The structures themselves are built to last decades — Conley's greenhouses from the 1960s through 1980s are still operating at schools and institutions — so the structure long outlives any single teacher.

Summer installation is a common goal for schools, since it avoids disrupting the school year and gives a new program time to get established before students return. Whether it's achievable for your project depends on your timeline — funding approval, procurement, engineering review, and manufacturing all happen before installation, and institutional procurement in particular can take longer than schools expect. The practical move is to work backward from your target summer and start early. If a summer install matters to you, tell your rep up front and they'll be honest about what's realistic given where you are in the process.

Schools are public facilities, so accessibility matters. Greenhouses can be configured with accessible entry and circulation — appropriate door widths, navigable aisle spacing, and bench heights that work for students using wheelchairs. Specific requirements vary by jurisdiction and by whether the greenhouse has general public access, so your local building authority is the authority on what your project needs. When you know your requirements, we can configure the structure to meet them.

Yes — greenhouses operate in every climate in North America, from Minnesota winters to Arizona summers. What changes by climate is the equipment, not whether it works. Cold climates need heating sized for the coldest expected day and structures engineered for snow load. Hot climates need significant ventilation and evaporative cooling. Your location drives those decisions, which is why one of the first things your rep will ask about is where the greenhouse will be built. The configurator and your rep size the equipment to your climate.

The greenhouse structure is one part of a complete project, and it's the part the configurator prices for you directly and immediately. Beyond the structure, a complete school project typically includes site preparation (grading, drainage, foundation work), utility connections (water, electrical, gas if you're heating), installation labor, permitting and engineering fees, and your first-year operating budget. The total project cost is meaningfully higher than the structure alone, and the additional costs depend heavily on your specific site and local conditions. When you build funding requests and board presentations, plan around total project cost, not just the structure. Your rep can help you think through what your specific situation is likely to involve beyond the structure.

Operating costs are mostly energy (heating and cooling), water, and growing supplies, and they vary widely by climate, by how much of the year you run the greenhouse, and by what you grow. A program running year-round in a cold climate has higher energy costs than a spring-and-fall program in a mild one. The equipment choices you make up front — particularly heating and cooling — are the biggest driver of ongoing operating cost, which is one reason it's worth thinking about operating budget during the design phase rather than after. Your rep can help you understand the operating implications of different equipment choices.
