Do you need to spray the new grafts after hair implant?

Hi. It is my second hair implant i just did. The first time, I was told to spray the grafts for first 3 days every 30 minutes, to keep grafts moist and to ensure scabs will fall faster. This is at least extremely common on internet reviews. Now my second time, different clinic, they told me not to spray at all, only wash every day and expectation from them is to send them a photo with my crust intact at day 14. if i leave the scabs and crust getting too hard, wouldn't it actually affect the grafts?
