Lol I'd happily pay more for those seeds, you don't realise how much breeding work has gone into that strain!, stabilised to 9 generations! and no one else has this strain in the seed business.
They will produce nicely like most kush types, I'll pick genetics over money anyday. No point buying cheap strains unless they are Mandala - check them out man, they have some really really nice strains for cheap.
Yeah you could do fem seeds for sure, maybe you could do a malawi x golden tiger making a 75-25 malawi-thai ratio'd plant or you could grow out the GT and seek out the thai dominant pheno and feminise that.
spray a cutting mate, not the mother plant to reduce hermy's.
