Regulation & Compliance
Source: HortiDaily The USDA Agricultural Marketing Service has proposed a rule that would allow synthetic carbon dioxide to be used in organic crop production under specific conditions. The proposal would add CO2 to the National Organic Program list for two uses: adjusting irrigation water pH and atmospheric enrichment in greenhouses

Source: HortiDaily Veganic is positioning a new class of products called Plant Primers as a preventive layer in crop management. Instead of reacting after stress is visible, the company says these products activate biochemical pathways that keep the plant in a state of “balanced alertness,” allowing it to respond faster

Source: HortiDaily Dutch greenhouse operators are dealing with a costly problem that often stays hidden until harvest. LED drivers can run below rated output for days without triggering alarms, creating light deficits that show up later as weaker fruit set, delayed development, and uneven crop performance. In the example described
