This whitepaper demonstrates that ‘optimally’-rooted cuttings (scores 2–3) maximize yield efficiency in no veg cannabis systems, while over or under rooting reduces performance. These results provide a practical, evidence based threshold for propagation, supporting uniform, predictable, and time efficient commercial production.

This whitepaper explores how drought stress during two flowering phases, transition and generative, affects plant height, yield, and cannabinoid content in medicinal cannabis. Findings show that phase-specific stress can guide growth and enhance quality but also creates trade-offs between yield, architecture, and chemical composition that growers must balance carefully.

Cannabis breeders can now predict seed traits before sprouting, thanks to breakthroughs in spectral imaging.
