Q.Seeds From Carrot Tops
Will growing carrot tops for flowering using the water or newspaper method described on site also provide viable seed?
The article https://www.gardeningknowhow.com/edible/vegetables/carrot/saving-carrot-seeds.htm I assume you referenced, discusses the methods of growing carrot tops. While many vegetables can been grown indoors, most will not produce viable seed IF they bloom. Vegetables need a minimum of 4 hours full sun (outdoors) to grow properly.
i think growing carrot tops for flowering using water or newspaper does describe the site provide viable seed because how would you grow carrots without a seed
