I used a 400w HPS Garden Light III throughout the entire cycle.
Two plants were grown in a 50/50 perlite/vermiculite medium in 2 gallon pots, using a drip hydroponics system.
The grow room (with lights on) maintained an average temperature of 78-85 degrees, but at night (lights out) average temperature was between 69 and 72 degrees.
GH Flora-series nutrients were used with very little variation from the normal recommended dose, and Kabloom was used throughout the second half of the flowering cycle at full strength.
Plants were flushed with plain water for the last seven days of the 8 week flowering cycle.
