Highly recommended for seedlings/young plants and as additional/supplementary/underside lighting during the growth/vegetative stage. They can also be used for propagation, just ensure there's adequate space between the light and canopy top - although these units are 'only' 40W, they're surprisingly bright and cuttings/clones may want some protection via distance or shade netting, for example.
