Should I build a godown or use rented warehouse for grain storage?

Build your own godown if you store large volumes every year and have land; rent a warehouse if your volume is variable or smaller. A registered warehouse gives you a warehouse receipt against which you can sometimes raise a pledge loan, lets you store without big upfront cost, and provides professional pest and moisture control. Building your own makes sense over the long run for big consistent volumes and gives full control, but needs capital and good construction (damp proof, ventilated, rodent proof). Whichever you choose, dry grain to safe moisture before storage, use proper bagging and stacking, and treat against insects. Holding stock past harvest can fetch better prices, but factor storage cost and quality risk.
