## Description

GROW LIGHT BULBS

Review: It might come defective
Review: Excelente producto - Lo compré porque en mi casa no entra casi nada de luz y me gustan mucho las plantas, algunas se me murieron y las pocas que quedaban dejaron de crecer, se etiolaron y en general no se veían bien. Ya llevan aproximadamente 20 días y ya presentan retoños, se ven más verdes, con brillo y las que tienen manchas más claras se están resaltando. Solo hay que tener cuidado de no exponerlas demasiadas horas porque se pueden quemar un poco las hojas o como en mi caso, que necesitaron hacer el cambio más progresivo. Lo único que no he podido evaluar es el consumo energético, pero vale la pena ver bien mis plantitas

## Features
