I dig the tga strains. Yes the phenos vary quite a bit. Sometimes there's alot of males (great for breeders). They are the fastest seeds I ever dealt with. They are the most colorful and have the most trichome development of any seed company. I've grown Dutch passion, sagmartha, flying Dutchmen, soma, dj short, sensi, green house, nirvana, atomic, Cali connection, dna, my own breeds. The tga I like the most. Then the problem with back crossing is those strains become IBL's or has ibl genes. Which makes them very sensitive to any stress. Can hermie very easily. Even an ibl female that's been female for years can mutate into a hermie. Look how bad imbreeding is with animals and people. If you plan on breeding. With so many phenos and so many people breeding. There's not one cross is the same. The only back crossing I'd like to see is on the pennywise. So we can all get some harlequin phenos that actually have some cbd..
