LIGHTING
WOULD LIGHTING BE COST-EFFECTIVE?
To answer this, we need to consider production and cost
levels. A production yield of 0.37 cuttings per every mole of
light was reported in our last communication (link above).
Using a market value of $2 per cutting, electricity cost of $
0.11 kW-1, L1000 HPPB efficiencies (3.1 μmol J-1), and our
reported yield per light (0.37 cuttings per additional mole of
light); growers can generate revenue of $0.73 from the extra
cutting production and spend $0.01 on additional electricity
per every mole of additional light. This suggests that
providing cannabis with high supplemental light intensities
is economically feasible for the cannabis nursery industry.
Note: This study was conducted on one cannabis cultivar,
'Suver Haze', we expect all or most cultivars to increase
their vegetative growth under these light levels and optimal
production conditions; however, the number and rate of
branches per mole of light can still be lower or higher due
to genetic differences between strains.v
Cristian E. Collado is an agronomist and agronomy
engineer who is focused on increasing production and
understanding plant and crop physiology while minimizing
the environmental impact. He has developed advanced
growing systems for greenhouse and indoor farm studies to
improve data quality, increase plant and crop physiology
knowledge, and reduce resource usage. Additionally, he has
designed a vertical farm multi-crop propagation chamber
used in precision propagation facilities. Since 2016, Cristian
has been a valuable NC State Controlled Environment
team member, coordinating CE research projects while
completing his Ph.D. Cristian's team has also been his wife,
Laura, and their two young daughters, Aylen and Lucia,
whom he has been proud to be a part of for over 12 years.
Dr. Ricardo Hernández, an associate professor at
North Carolina State University, focused on controlled
environment research, specializing in optimizing
environments to maximize plant responses. As the
director of the CEA-Coalition at NCSU, he heads a
multidisciplinary research group. Collaborating with
scientists, engineers, and industry partners, their evidencebased
research aims to reshape CE agricultural practices
for a more sustainable future. Current CE research projects
include Indoor-propagation (vegetables, berries), Cannabis,
Speed-breeding, Vertical farm molecular breeding, and
Agrivoltaics. Beyond academia, Dr. Hernández has a
doctoral training in entrepreneurship and co-founded
two startups: Grafted Growers (graftedgrowers.com),
specializing in vertical farm plant propagation, and
Phlora (phlora.com), focused on advancing vertical farm
technology development. Dr. Hernández's work spans
academia and entrepreneurship, driving innovation and
sustainability in CE agriculture.
