Why you use anhydrous ether during the preparation of Grignard's reagent why not anhydrous hexane?

You should really use anhydrous hexane; however, ethers can absorb large quantities of water; THF is completely miscible with water and will thus require extensive drying in order to get an anhydrous environment. Hexane absorbs very little water due to the unfavourable interactions between it and water. Therefore "non-anhydrous" hexane contains such a small quantity of water that the Grignard reagent formed will more than adequately dry the hexane.
