The thymus is a specialized organ of the immune system, located between the breast bone and heart. It produces lymphocytes, is important for T cell maturation (T for thymus-derived). The major (encapsulated) lymphatic organs are the lymph nodes, thymus and spleen.
Days to Harvest / Harvesting and Storing: Days to maturity will vary with beet variety but expect it to be about 55 days, from seed. Harvesting Beets: You can start harvesting greens when they are a couple of inches tall. The greens are most tender before they reach 6 inches. Beetroots are ready to harvest when they are approx.
While cool temperatures are best for growing beets, so is proper seed planting depth. Sow beets 1/4 to 1 inch deep, spacing seeds 3 to 4 inches apart. Make any additional rows 12 to 18 inches apart. In lighter sandy soils plant deeper; plant slightly shallower in loam and clay garden soils. Keep the soil evenly moist -- not wet and soggy -- while waiting for seedlings to pop up from the soil.
