HPI Controlled Environment Agriculture (CEA)
Clean Vision. Total Control.
CEA is no longer the future — it is the present. Our HPI CEA division leads the science of sustainable production through precision plant nutrition, contaminant-free growing systems, and proven IPM strategies. Under our Clean Vision™ initiative, we ensure food and flower production meets the highest safety and quality standards.
Our CEA Programs (Nutrition, IPM & Hygiene):
Cannabis
Medical Cannabis Systems
Phytochemical precision through data-driven inputs, water modeling, and clean IPM.
Our cannabis platform focuses on nutrition, water-nutrient modeling (HPI HydroLogic), and contamination control. From vegetative to late flower, we control key nutrient ratios, root zone dynamics, and IPM strategies to ensure optimized terpene expression, cannabinoid profiles, and clean compliance.
Lettuce
Hydroponic Lettuce Systems
Precision-grown for nutrient density, shelf life, and safety.
HPI’s lettuce program focuses on closed-loop hydroponic systems (NFT, DWC, coco slabs), optimized for rapid growth, compact heads, and minimal microbial risk. Nutrient programs emphasize nitrate over ammonium for controlled morphology, while silica and calcium profiles ensure leaf integrity and post-harvest longevity.
Tomato
High-Tech Tomato Production
Optimized solute transport and fruit density through targeted potassium and EC control.
Tomato production under CEA requires high-transpiration control, balanced vegetative-reproductive management, and pathogen suppression. Our program integrates calcium, magnesium, and potassium-driven strategies to maximize brix levels, flavor, and resilience against blossom-end rot and fusarium.
Pepper
Capsicum Performance Program
Engineered capsaicinoid expression and stress tolerance via tailored micro-macronutrient interaction.
The HPI Pepper program emphasizes flower retention, balanced N:K ratios, and enhanced boron-calcium mobility to improve fruit set and uniformity. High transpiration crops like peppers require robust VPD management and supplemental silicon for abiotic stress reduction.
Cucumber
Rapid Cycle Production
High-output vining managed with tight EC precision and tailored auxin response support.
Designed for high-frequency harvest, the cucumber program supports fast vegetative expansion and controlled fruit loading. Emphasis is placed on calcium:sodium antagonism, sulfate-driven micronutrient delivery, and Trichoderma root enhancement to reduce stress-induced deformation.
Strawberry
Day-Neutral Systems
Flavour and firmness built on root zone stability and potassium-calcium synergy.
Strawberries demand delicate EC control, oxygen-rich substrates, and consistent silicon and potassium flow to enhance brix, fruit firmness, and shelf life. Our CEA strawberry solution integrates root zone pathogen suppression with optimized fertigation pulses and bloom-phase biostimulants.
Blueberry
Substrate-Based Low pH Systems
Anthocyanin-rich yields built on acidic substrate compatibility and precision iron delivery.
The blueberry program targets soilless substrate cultivation with a focus on pH control (4.5–5.5), Fe chelation stability, and root microbiome health. Potassium, manganese, and silicon play key roles in enhancing color, flavor, and shelf life in high-value controlled fruiting environments.
Leafy Greens & Herbs
Multispecies Program
Rapid biomass development and terpene expression managed through dynamic EC and foliar defense.
Tailored for arugula, basil, coriander, and mixed greens, this program supports short-cycle, high-turnover systems. Focus is on nitrogen form, magnesium:calcium balance, and microbial foliar support to drive chlorophyll production, aroma, and clean leaf structure.
Spinach
Oxalate-Safe Nutrient Strategy
Dense iron and folate delivery with clean residuals and reduced oxalate risk.
Spinach is nutrient-sensitive and prone to oxalate buildup and microbial contamination. The HPI Spinach program delivers balanced ammonium:nitrate and magnesium:potassium strategies to enhance yield and leaf quality while mitigating pathogen risks through water management and foliar microbiome support.
