Greenhouse Growth: What New York Growers Need to Know

In recent years, New York has opened the door for adult‑use cannabis cultivation. Yet many growers still lack clear data on how much they can expect to produce and earn in a greenhouse setting.

A new study tackles this gap by comparing two popular flowering methods:

• Autoflower – does not rely on light cues.
• Photoperiod – follows a strict day‑night schedule.

Study Design

The research was carried out inside a commercial greenhouse in New York State, where both types of plants were grown under identical conditions.

Key Findings

• Photoperiod plants typically yield more per square meter but require longer cultivation cycles and more energy for lighting.
• Autoflower plants finish flowering in a shorter time frame, allowing more frequent harvests and reducing overall production costs.

Economic Implications

• Photoperiod systems generate higher gross revenue per plant, yet their net profit margin is only slightly better once operating expenses are accounted for.
• Autoflower growers may achieve comparable profitability by scaling up operations or targeting premium markets that value consistency.

Recommendations for New Entrants

New entrants to the New York market should weigh their:

• Capital constraints
• Energy availability
• Desired harvest cadence

before choosing a strategy. The choice between autoflower and photoperiod hinges on balancing yield potential, cost control, and market positioning.
