Grow Your Opportunity Now

We can support your growing and processing projects, regardless of size and at any stage or with complete turnkey solutions.

Here’s a summary of how Prospiant, a Gibraltar company, can help your business, research or community institution as well as high schools and universities.



Design Your Project With Expert Consultation

Prospiant offers complete architectural design, advisory and consulting services. Our team includes licensed architects, engineers and other experts on staff, and a network of proven contractors who will help design and test sites as part of site development for your project.



Build With Turnkey General Contracting Services

Our team of experts on staff and proven network of general, electrical and mechanical contractors can help you prepare sites, build greenhouse and indoor growing structures, and install benches, tables, grow gutters, racks, trays and drain water recirculation, roof glazing, ventilation and light abatement.

In addition, we can help you with processing and prep facilities. For extraction equipment and lab design, we offer cannabinoid extraction technologies, including CO2, ethanol and solventless. Other processing and refinement technologies available to you from Prospiant include C1D2 processing labs, chilling, distillation, evaporation, extraction and filtration.



Integrate the Perfect Growing Environment

Prospiant assists with the software and hardware integration of critical equipment and systems that enable growing environments such as air quality and odor control, artificial lighting, CO2 dehumidification, heating, refrigeration and ventilation, irrigation and fertigation, shades and curtains. In addition, we offer artificial lighting, sorting and packing equipment and water disinfection.



Operate Your Facilities in Optimum Condition

Once your facility is constructed, you’ll need products, services and equipment to support ongoing growing operations. Prospiant provides aftermarket parts and repair, consumables, preventative maintenance and emergency repair.

Collectively built by our six industry-leading brands, Prospiant embodies long-term stability with unmatched financial strength and end-to-end expertise gained during more than 185 years of combined business success.
