How do you know theyre high quality?
Edit - just seen the pics and looks like youre growing from seed, I hope you end up with some pearlers there but its always a gamble with seeds. To get something really special you need lots of seeds of each strain, grow them all out to figure out your favourite and then just clone.
Personally hate seeds indoors these days as its too time consuming finding a keeper. Better off just going with tried and true clones.
Good quality seeds from reputable breeders are nearly always A grade smoke but those reallt special plants are hard to come by.
