Hydroponic Biomass Acceleration

An empirical investigation comparing organic mineral solutions against traditional soil medium in rapid leafy crop germination for modern vertical urban farming.

Scientific Premise

Grade 6 Research Capstone
The Core Hypothesis

If micro-dosed organic sea-kelp minerals are introduced into a closed-loop recirculating water medium, then seedling biomass will increase by >50% within 14 days without increasing energy consumption.

Duration

Experimental Methodology

Controlled Protocol
Phase 1

Baseline Preparation

Calibrated twin hydroponic pods with identical LED spectrums (450nm/660nm) and regulated water temperature at 21°C.

Verified in Lab Journal
Phase 2

Nutrient Infusion

Administered custom organic mineral broth to sample cohort B daily at 08:00 AM while keeping group A on standard solution.

Verified in Lab Journal
Phase 3

Photometric Logging

Measured lumen reflectance and root branching density every 48 hours using a calibrated digital spectrometer sensor.
