gwt a mini microscope and look @ the tricomes..the color detemines the high and thats when u decide when to flush & cut...
jcervantes has a book that will answer all your questions now and forvever....
get a timer and move on to the next level..dont let these things slow u down..
Get a Timer...maybe one day u can upgrade to a computer...but one step @ a time..good luck
trichomes is the only way imo.
get yourself a microscope.
i like mine when couchlock style...so i leave it there...patience is a virtue,especially with these ladies...
