Yes...I have grown the white urkle...I can honestly say either one of those strains will not disappoint. The white urkle produced slightly smaller tight compact buds , a very light purple coloration on most flowers and it was WHITE as snow, glistening with trichombs. The high and potency is as good or better then the most potent strains on the market. OG RASKEL, CALI CONNECTION, ALIEN GENETICS...and there are others...if you can obtain genetics from these guys...do it. I have grown for years...in fact, I know I am without doubt one of the older guys on this site, by older I mean age, just based on what I read...I have grown out many strains from many breeders from around the world over the course of many years but for this ol guy...North American Genetics still rock. I was torn as well when choosing, thats why I bought every avail strain that I could get my hands on from all these guys....I buy regular seed because I breed for my own purposes...not for distribution and its super nice to know that no matter what strain I choose to grow each round...I am NEVER disappointed.. Good luck Peace
Well let me put it this way..I used to buy regular...its getting to the point where all you find are fem seeds these days,,,dont get me wrong, thats whatever...people want to buy fem..knock yourself out but for breeding purposes you need Reg's man!!!
