ok whoops he made a mistake dont burn him to bad for it ,lol.hi cannabis yeah those will probably not yield much as if u didnt know all ready im sure .atleast you'll get a lil bit of smoke and some experience.some friendly advice though,next grow if u use those lights LST your plants by simply bending the top at a 90 degree angle so u can get the lights closer to more of your plant and you'll get more than 1 cola also.If u have the money to invest in some compact fluorescents those wpuld be way better because u can put them really close to your plants.I would suggest getting,6 to 8 100 watt output warm bulbs. hope this helps peace
