Thanks for the mention AT...my trials with defol and topping were more for canopy management,but anybody who has read my mainline thread can see that the only technique that improved yield was a single fim,there may have been other variables to cause this,but my test did improve the fact that more light to lower branches resulted in near zero popcorn,keep in mind all plants were grown in 2 gallon fabric pots with 600 watts of HID,,a more realistic experiment would have most variables removed,have multiple plants of the same strain to eliminate pheno traits and be run a few consecutive times to gather a summary/data..i have fun training them and it breaks the boredom of just watching and watering,but with the heavy yield strains that i have trained,yield was above breeder expectations but below par when not stressed..i do it cause people say not to,hardheaded ya know...anyone is free to add to my journal cause this info is what helps us gain knowledge and grow as a site...+1 to those willing to think outside the box !!!
