Everything I've had from Barney's excepting maybe a couple individuals of Blue Cheese and Critical Kush have been excellent. Yes, there is a fair degree of phenotypic variation, but when you get the beast bitch, she's absolutely nasty..
I've seen a bit of trashing of Tangerine Dream, funny because it's one of my most enjoyable grows. The first time I tried it I had two beans. Both ended up with central colas - not exaggerating - just about the same girth and length as 330 ml soda cans. This was under a 400W dual spectrum HPS and in a half metre tent with four other ladies. Large fist-sized top colas, each of them, and dense sub-nugs. They were long and stretchy, and in the last two weeks probably added another third in mass. Currently, I have a batch of five more on the way from new beans (sadly that was a long time ago and couldn't take cuttings): two are the same kind of stretchy phenotype and are starting to bulk out as the last ten days or so approach. Another two are medium height with already super dense nugs of medium-large build. The last is more squat, more cheese-looking, more flowers overall but smaller main cola, and ripened earlier. I also have a Cookies Kush with this batch, which is OK-ish, the main cola will be decently sized and dense when done.
I've also had good previous experience with Utopia Haze, G13 and Pineapple Chunk. Pineapple Chunk was absolutely immense last time, bulking out greatly in the last two weeks, with fantastic tropical stench.
My next round under a 600W and larger space includes Utopia Haze (3), G13 (3), Pineapple Chunk (3), Amnesia Lemon (Free; 1), Cookies Kush (Free; 1), Critical Kush (Free; 1). Can you tell I like hazes?
I expect to see good results based on prior experience. As suggested, when you find the right pheno make it the mother. There are more than a few I wish I had kept (just a practical impossibility)... sigh!
