Roots Organics Uprising Foundation is a diverse blend of natural and organic ingredients specially formulated for maximum results. When used alone as an amendment or top dress, Roots Organics Uprising Foundation is very effective for supplementing calcium, magnesium and iron. However it is particularly effective when blended with Roots Organics Uprising Grow for a plant's vegetative growth phase and with Roots Organics Uprising Bloom for the bloom phase.
