Frequently Asked Questions About Cannabis Cultivation

Commercial Cannabis Cultivation

What can automated irrigation systems do?

Automated irrigation systems are efficient for growing cannabis indoors. In addition to programming and regulating water distribution, these systems are effective in identifying irrigation issues before they have the chance to affect your plants. While they can be costly, automated irrigation systems are a long-term investment that will save you time, money, and water.

Can GEM help with air filtration for commercial greenhouses?

Most greenhouse environments are not sealed, instead using a system of forced air pressure. Depending on what your facility requires, our team can help install, maintain, and repair efficient air filtration systems like HEPA filters or air scrubbers and purifiers to sustain clean and healthy air for both you and your plants.

What type of HVAC system do I need for my cannabis greenhouse?

As with most greenhouse or cultivation facilities, proper ventilation is essential in maintaining the growth and health of your product. Depending on the size and operation of your facility, you may require a DX (Direct Expansion), mini-split, chilled water, VRF (Variable Refrigerant Flow), or rooftop HVAC system to reach maximum efficiency. Regarding your decision, our team is on call to guide you through HVAC installation, repair, and maintenance.

What type of lighting and racking system do I need?

At GEM, we’ll help determine whether your facility requires stationary or mobile vertical racks, and what types of drying technologies would be most beneficial to your particular setup and growth goals. If you have a compact vertical cultivation environment, LED lighting is optimal for growing your product.
