Fuck off loser. Even if you could read you are incapable of understanding any of the material.
On topic. I personally don't "try" to get bigger colas. I simply start out with good seeds, decent light, hempy buckets and Lucas formula. This ain't rocket science. I figured it up last night and I grow for about .25 to .50 a gram. I want small fast plants and love autos for this reason, but will do photos going 12/12 with no more than a 2 week veg. Weed is so easy to grow its pathetic and takes very little effort when you have dialed everything in and just give the plants what it needs. Key statement. Give the plant what it needs to grow itself. I think that's why most peeps fuck up there plants.
Another thing. I have noticed in the past, that even seeds from the same pack from even great breeders like Dinafem or WOS sometimes give different results. Critical Jack didn't yield very well for me, but the smoke was over the top. Different people will have different growing styles. Since I am a light smoker an O of top shelf will last me for a long time. I would rather have an O of Dinafem Critical Jack or Amnesia or WOS Afghan Kush than a pound of brick weed. Never mind, make that 10 pounds of brick seedy crap. I don't want that at all.
Those involved in the commerce will probably feel differently, but it's about the quality for some of us.
