nirvana is good for the price.i haven't ordered more costly seeds but i would expect more uniformity.however lots of differnt phenos isn't always a bad thing.just keep moms of every plant until you smoke it's offspring then toss them shitty ones and keep the garden full of the good ones.it is alomost like growing multiple strains.i have grown thier white widow(she is kinda touchy,doesn't seem to like chemicals,sativa pheno rocks!)and thier aroura indica(one tough bitch,greasy with trichs,looks,smells,tastes very nice,once again sativa pheno rocks!highly recomended):stoned:
