  We propose and analyze two series of clustered quantum Hall states for
rotating systems of spin-1 bosons. The first series (labelled SU(4)_k) includes
the exact ground states of a model Hamiltonian at large angular momentum L, and
also for N=3k particles at L=N. The latter is a spin-singlet boson triplet
condensate (BTC). The second series, labelled SO(5)_k, includes exact ground
states at large $L$ for different parameter values.
