Solutions Created to Fit the Commercial Indoor Greenhouse
InPlant’s employees have years of experience developing office space and production flow solutions for customers. We will custom-design a Modular Building System within your space constraints and around any equipment obstruction. Our fabrication matches your exact dimensions within a fraction of an inch. As a result, we can engineer a unit that’s as economical, intricate, or heavy-duty as you require. No job is too small or too large — from a single Grow Room to a multi-story agricultural complex.
InPlant’s clients include the world’s largest laboratories, retailers, automobile companies, manufacturers, secure government facilities, variously sized warehouses, and numerous other organizations.
Durable Products Maximize Return
Your Modular InPlant Office or Grow Room can expand, reconfigure, or relocate as your company evolves and changes. The design of our Building Systems will remain non-progressive. As a result, Wall Panels can be upgraded or replaced to include windows or doors without disturbing an adjacent section. Modular also means installing new equipment at a lower cost as your business grows and industry standards evolve. Because of our commitment to service and our product’s flexibility, you’ll save time and money in the future.
Several innovations make InPlant Grow Rooms eco-friendly as well as cost-effective:
- Reflective surfaces—maximize light and energy efficiency.
- Excellent Insulation—helps maintain a consistent temperature.
- Tight-Fit Assemblies—Grow Box construction eliminates light leakage during dark hours, reduces air infiltration, and saves energy.
- Seamless Integration—with environment controllers and grow room timers, lowers energy consumption and saves time by allowing remote control.
- Durable Materials—these promote the long-term use of your indoor Grow Room, and with modular flexibility, they support global environmental sustainability efforts.
- Relocate & Reconfigure—InPlant’s non-progressive designs ensure that your system will adapt to future business needs.
