Edwards' side kick off with a game against England on Saturday February 5 at Parc y Scarlets but despite their inexperience Edwards is demanding the highest of standards.
"We are building towards the Junior World Championship and our first game, a tough challenge against England will certainly give us a benchmark to gauge where we are," said Edwards.
"England will be well-prepared, they have the likes of Owen Farrell, Manu Tuilagi and George Ford in their ranks, and the majority of their squad has moved up as a unit from the most successful England Under 18 side in history.
""There are some players currently unavailable to us through injury such as Thomas Young, Lloyd Peers, Ben John and Dale Ford but there will be no guaranteed right to step back into the squad when they regain fitness, there will be no comfort zones.
"We are treating this group of players as we would a professional team. We will follow a two-day on, one-day off training schedule from now on.
"Time is tight so we will be focussing on the basic principles and key aspects of the game which we will judge ourselves on and we'll go from there."
