Educated at Piarist schools in Szczuczyn, Łomża, and Warsaw, he became interested in plants through his teacher E. Andraszek.
He then studied at the Royal University of Warsaw (1821–24) and received a master's degree in zoology under Feliks Paweł Jarocki.
Waga then became a teacher at Piarist schools in Warsaw and Radom from 1825 and continued until his retirement to Łomża in 1862.
While teaching in various places, he explored the plants of the regions and in 1829 took part in an expedition along with Szubert and Jastrzębowskiet which resulted in a large herbarium collection.
A statue of Waga was installed in the Botanical Garden in Warsaw which was destroyed in World War II and reconstructed in 1964.
