Ideal onion conditions

I purchased some loose onion bulbs from the local gardening club and they advised me to keep the soil as dry as possible.

Is this right? If they are covered underneath a polythene tunnel how often should I be watering them....at the moment they are just under the soil and the shoots are coming up
