When considering the intricate process of seed germination, how often should I water seeds to facilitate optimal growth? What factors should I contemplate that might influence the frequency and quantity of water needed for these delicate embryonic plants? Is it merely a matter of adhering to a rigid schedule, or should I be attuned to the specific moisture requirements dictated by various seed types? Moreover, could environmental variables such as temperature, humidity, and soil composition play pivotal roles in determining watering frequency? Should I be vigilant in assessing the soil’s moisture levels, employing techniques like the fingertip test or moisture meters to gauge hydration? Are there particular signs indicating when the seeds are adequately watered, or conversely, when they might be experiencing drought stress? How can the different growth stages of seeds alter their hydration needs throughout the germination process? What strategies or methodologies can be employed to ensure that my seeds flourish with the proper amount of water?
