Currently HID lighting is the best to use for biggest yields, nothing is going to help more than vegging for longer periods so you have a bigger mature plant going into the flower cycle. If you are not vegging for at least 5 weeks and doing more than one transplant then you will not get much yield no matter what the strain is because the plant was not mature in less than 4 weeks and if your transplanting from a cup right into a 5 gallon bucket your plants rootball is weak and non existant. There is a major difference between someone who lets a plant get almost rootbound (shape of a rootball) and then transplants into a bit larger allowing the plant to again get almost rootbound (mine take 2 weeks per pot to rootbound aprox) if you just stick a plant from a cup to a huge container the roots go directly down and directly sideways like branches yes there is nothing at all inside this 5 gallon bucket like there would be if there was a softball sized rootball that was put into a bigger to become a bigger rootball and so and and so forth. Veg for longer periods and get the bigger lighting 600w I believe puts out 90,000 lumens anything less is toying around and why ask how to do it if your sitting there with some CFL bulbs and light leaks. Good luck and go with the flow, only you will know what works best in your enviornment by trial and errror and these are just some tips. Smoke on ......
