Day-Length Decreasing = Time to Adjust Your Water Content

Amid the usual distractions of modern growing life, it’s easy to forget that Autumn 2026 is just around the corner. As day length shortens, now is the critical moment to review and adjust your irrigation strategy. Unlike previous years that brought prolonged dry spells or extreme heat, this year’s weather has been variable. Across the country, many regions are already seeing heavy rainfall and several cloudy days in a row. While this is great for replenishing water reservoirs, it also creates challenges once the sun returns: crops may wilt, and the temptation to overwater is high. My advice: keep substrate water content and EC close to pre-cloudy levels.
