I've never ran blue widow, I was gifted a rooting clone in rockwool that's still in my makeshift humidity dome. So I wouldn't want to get your hopes up. Just read as much as you can. Books and RIU are your best friend at this point, they will help you learn about the plant, how it grows, training techniques, and help you work thru problems. RIU has been a huge help just to read thru the threads and see real grows with real results.
If any, more experienced, growers or someone who's ran blue widow sees an error in my advice let me know cause its what I go by so I'd like the corrections myself!!!
