First let me say .... I just ordered 10 nirv seeds from doc chronic. The strand is bb x nl. The yield says 550/600 . This is my first time grow and i've made the box myself. The box is 2.5ft x 2.5ft x 5ft tall. It is totally light proof, intake and exhaust fans as well as 1 fan blowing lightly down towards where the plant will be. Im using a dripp system that I got from general hydroponics. The system is a single bucket. The light I got is a 250watt hps and a 250watt mh for the veg. The walls of the box are all mylar and everything seems to be done right. Now heres the question! To hit maximum yeild under a 250watt light in these conditions would you grow 2 plants or just one. Maximum yield while having a potent plant is my goal and that is why I chose a strand crossed with Big Bud. Also, will the 1 bucket system from general hydroponics be big enough to grow 2 full size plants out of. ? The bucket looks to be a few gallons. Any help / comments would be great. -skimp
