Garcia handed another start to 20-year-old midfielder Rohan Ince in Saturday's Burnley win.
Fellow rookies Jake Forster-Caskey and Solly March, both 19, were also introduced from the bench for the injury-hit Seagulls.
"We trust in our young players. I want to see all the positive sides of our players," said Garcia.
"We have had many injuries but we also have young players who want to improve.
"They are helping us at this moment and I am very happy with all of them. I played three young players and this is what we want to build here - to have many players from the development squad as soon as possible."
Midfielder Keith Andrews missed the victory with a hamstring injury while top scorer Leo Ulloa twisted his ankle, although he expects to be fine for next weekend's visit of Millwall.
