Bulbs as close to the spectrum of the sun you will get! The lamp is full-spectrum so will produce the goods in both veg and flower - expect increased growth, tighter internodes, and better overall vigour and an increase in final weight. It also has an increase in the red spectrum which gives a definate boost during flowering.
