ok,ive done 2 years of research on this,very extensive.The most potent,best yielding, earlier finishers for outdoor growing are Maple Leaf indica from Sensi,Mendocino Madness from TH seeds,Sweet God from BC Bud Depot,Sensi Star from Paradise,Kish(formerly Shiskaberry)from Cash Crop Ken,Purple Skunk/Dutch Treat from East Island seeds, Northernberry from Peak seeds.Also go to "unleash da green forum",they have a good array of really early finishing potent hybrids,and i mean done by the first week of September and as early as late August,supposed to be real potent too,go for the "geurilla Gold#5".Hope this helps!Im growing Sweet God,Aurora indica and Jack the Ripper.Igrew the JTR indoors and was very dissapointed in the potency,it was supposed to be killer and it sucked!Looked awesome though,most crystals i have ever seen on a plant,just was'nt too potent.
