Soma is said tobe 1 of the stablest as is Mr nice.!
But a hybrid will always have variations .
You can get variety's with 2 phenotypes but none can ever keep it isolated to 1.
even C99 a stable back cross as some variation
Na I cant agree their!
Some of the IBLs like Herijuana maybe but none of the hybrids are very stable.
subcools are f1 crosses (f1xf1) and some f2s of popular variety's .
When their proper potent plants i wouldn't say their the most uniform
greenhouse, usually always end up with nearly the same plant but that also depends on the breed, breeds that are good as a different phenotype is better to suit ones taste, but i guess if they find the best then they keep it, fuck, rambling.....high....
