Are you growing a C4 crop? Maize, millet, Sorghum, Bermuda Grass etc
This episode explains C4 photosynthesis (the Hatch–Slack pathway), how it concentrates CO2 around rubisco to reduce photorespiration, and why C4 plants perform exceptionally well in hot, dry, high‑CO2 conditions.
It covers common C4 crops (maize, sugarcane, sorghum, millets, tropical grasses) and practical hydroponic tips: increase light intensity, temperature, CO2 levels, and support with extra nitrogen and magnesium to maximize growth.
The episode also highlights a 2024 study showing humic acids can strongly boost photosynthesis in C4 plants and encourages growers to investigate…
