A capillary hydration system and method for facilitating the growth of plants are provided. An exemplary system comprises a base having a reservoir for holding nutrient solution, and an insert portion. The insert portion comprises at least one downwardly extending plant receiving depression that is capable of holding a growth substrate. The plant receiving depression has at least one capillary opening such that when the capillary opening is in liquid communication with the nutrient solution in the reservoir, nutrient solution is wicked from the reservoir to the growth substrate by capillary action. In accordance with various exemplary embodiments, the capillary hydration system may further comprise cover, including a cover with a supply component for refilling the nutrient solution without removing the insert portion or the cover, and a nutrient supply level indicator.
