Phillips 315w Master CDM Grow Lamps generate a greater level of useable plant light (photosynthetically active radiation) and run with a blinding intensity that's immediately apparent to the naked eye. The lamp is full-spectrum so it will produce the goods in both veg and flower – expect to see increased growth rates, tighter internodes, an improvement in overall vigour and an increase in final weight. It also has an increase in the red spectrum which gives a definate boost during flowering.
