HPS is the best for flower because it puts out more Lumens per watt.
T5's are as close as you are going to get to HPS in Lumens with Floras.
As I said before,,I use the T5's cause I got a very good deal on a complete setup,,fans and all.(consignment deal)
When I get the money,,I will go to a 400 watt HPS for Flower and my 320 watt T5's(30,000 lumens) for Vegg,,,but for now,,my T5's are growing me some very nice smoke. AND,,,,,,,,it aint off tha streets,,, from a dealer.:hubba:
