Thanks for your responses, unfortunatly I would like to limit myself to about 50watts for just growing my mother and max of 100watts when vegging my clones and no more these are my limits. I have decided against the MH and im gonna get a T5 High Output lighting fixture. Probably a 2 foot either 2(48w) or 4(96w) tube fixture. I want to get the 4 tube fixture and I was wondering if I remove one of the tubes will all the lights turn off? Does it have to have all 4 tubes in order for the light to function? I want to do this so when I'm not vegging my clones I can just turn off 2 of the bulbs and just use 2 of them to veg my mother and keep power down. anyone know? The 2 bulb one produces 4000 lumens and the 4 tube one produces 8000 lumens. How tall can I veg my clones with these lights before they start to strech significantly? I will be using reflective material to surround my grow chamber, space is not a limitation for me only power.
