How do I do kalaśa sthāpanā (ghaṭasthāpanā) at home, and when?

on Pratipadā morning, in the muhūrta given by the panchang, set up a water-filled kalaśa with mango leaves and coconut over a bed of soil sown with barley.

Ghaṭasthāpanā invites the Goddess into the home for nine days. It is done on Pratipadā, preferably in the morning; classical digests advise avoiding Citrā nakṣatra and Vaidhṛti yoga, and when that is not possible the Abhijit muhūrta around midday is used. Your panchang or Chiluka’s Muhūrta page gives the exact window.

Steps: spread clean soil or sand in a wide clay tray and sow barley (jau). Place a copper or clay kalaśa on it filled with water, a coin, betel nut, a little rice and Gaṅgā-jal. Arrange five mango leaves at the mouth, place a coconut wrapped in red cloth with mauli on top, and draw a svastika on the kalaśa. Invoke Gaṇeśa first, then the Goddess, and light a lamp.

Water the barley lightly each day. Its green shoots, called jaware or jayantī, are seen as the Goddess’s blessing.
