Best Grow Lights for Bonsai
Updated How we research
Tropical species kept indoors rarely get the light they need, and the usual result is stretched growth, long internodes and thin, oversized leaves. A grow light closes that gap. Lights vary in spectrum, in actual output rather than the wattage printed on the box, in the area they cover and in how much heat they throw. Distance from the foliage changes effective intensity more than most people expect. We weighed usable output and coverage against build quality and noise from any cooling fan. We also looked at whether the fitting can be raised as a tree grows, and whether it takes a timer without extra hardware. Small clip lamps suit one ficus on a desk. Panels suit a shelf of tropicals through a long northern winter. Temperate species belong outside, where they can take their proper dormancy.
