ive got a sumaster 600w hps super delux bulb it says 90k + with a bit of blue spec in it for less strech
ive been impressed with it so far and i got it cheap

now when i drop the screen on ill turn all the plants opposite ways so they all grow away from the centre of the light and the smallest lowest shoots will be in the centre of the screen and get the strongest light and the main tops will be on the outside of the screen
hopefully this will lead to a even canopy

also droped the light down to 14" temps 24-26 c
