We show that the supergravity embedding of the R+R2 theory naturally decreases the size of the acausal homogeneity, required for the low-scale inflation to occur, thanks to the presence of the dynamical pure supergravitational ``auxiliary'' fields. We examine the evolution of the R+R2 fields within a FLRW Universe. We also find a dependence of the initial conditions problem on the background spatial curvature. ER -
