dc.description.abstract The objective of this project was to establish horticultural management recommendations for each growth stage of cannabis with respect to growing medium, light quality and flux, temperature, and CO₂ supplementation. A peat-based potting mix produced longer roots compared to peat plugs; however, rockwool media resulted in 97% rooting success. There was no effect of light quality on root dry mass; however, the cuttings under red light exhibited significantly more and longer roots. Low light acclimated plants exhibited contrasting Net Carbon Exchange Rate (NCER) responses to 15 light spectral qualities; no differences in NCER were observed between 15-32°C. NCER responses to light and CO₂ concentration indicated optimal light intensity of 410-960 µmol m⁻²·s⁻¹ and ~1600 ppm CO₂ for stock, 21 DAP vegetative and 35 DAP flowering plants. Plants in a peat-based mixture with slow-release fertilizer exhibited higher floral yield than organic mixtures. en_US
