the querkle is a nice smoke but he odds of finding a purple pheno with purple buds may be hard with one pack. to me there are two types of purple strains: strains who leaves turn purple and strains who buds turn purple. querkle has purple buds but you gotta find the pheno. She is a slow vegger also, but smoke and taste is great.
One strain that i would suggest is sannies killing fields. This is definitely a strain for the novice because you can put it into flowering with little veg time (meaning that you dont have to spend time to care for her much in veg, where many problems occur) plus you are guaranteed to find a purple pheno in a 10 pack. Hell there are at least 3 phenos. pink, dark purple, light purple, and a green pheno. good yields, kick ass smoke, and taste and smells like berries/grapes/lemons. You cant go wrong with that.
DPD is another purple strain worth looking at
Black rose is another.
If you have access to clone urkle is definitely worth a look.
