Pick up a supply of growing trays and mini-pots at your garden centre. Make sure they're the kind that allow good drainage. Also get some sterilized potting soil - important to prevent seedlings being attacked by soil-borne disease or fungus.
If starting thyme from seed, begin the plants indoors in a shallow growing tray about six to eight weeks before the last frost is expected. Use a well-drained tray and do not pack soil too tightly.
If you don't want to build your own, there are several pre-designed indoor lighting kits that provide the light fixture, bulbs, table and growing trays. Although some assembly is usually required, most come with easy-to-follow instructions.
A submerged pump operated by a timer fills the growing tray with nutrient solution, which drains back down into the reservoir below. The Ebb and Flow system works best with water-retentive growing mediums such as Rockwool or vermiculite.
In its basic form, the ebb-and-flow unit consists of a growing tray and reservoir bucket connected by a tube. The tray is flooded by manually raising the bucket and drained by lowering it.
Other names include cell pack tray and growing tray
