  1. I'm debating in my head wether I should light my vegging cycle with 18 hours a day or 24 hours a day. I'm using a 1000 watt MH light and can see the electric bill not being as high, but is there a downside to this? Will the vegging cycle take longer with less light per day?
     
  2. you should do 18.6 with any light for veg. fuck that 24 /7 crap . it stresses your plants out .. about the elect. bill .. not to worry theres not that much of a difference with just 1 light , 4 however would cause a nice spike .. gl
     
  3. I agree with Dss....theres no where in the world where mj grows naturaly with 24hrs of light so why do it in a grow room...think my veg light is only on 17hrs a day...
     
  4. i have herd that if ur bill goes up u can put a magnet of some good size on top of that lil gray box outside and it slows the little nedal thing so maybe people can give that a try i run a 125W inferred heat bulb and my plants do good i keep it cool with a fan system i have made its really cool
     
  5. yeah i agree when i had my seedlings in 24 hour light the almost all died and now my new ones are under 18-6 and the are growing superb
     
  6. Think of it this way when a person lifts weights to get their muscles bigger your muscles do not grow as you are working out they grow when you are sleeping. And also this is when a person grows more is when they are sleeping. I have done a plant 24/7 and it has worked fine, but in reality a plant needs a dark cycle to grow effective. When the light is on the plant is storing as much energy as it can. When the light turns off the plant is actually building itself using the stored energy and nutrients it has available. I personally would pick 18/6 over 24/7. Not only that your electric bill would also be saved especially running a 1000mh. That 6 hours will save you more then you think. GL
