My own.
More robust, equivalent quality.. even the minimal variety of flavor is nice.
when i grow breeder seed, i plant 5-10 and many are trash-dick plants. when i pop my F1's they have a signficantly higher likelihood of being strong plants. I don't have to cull as many on average. The green poison F1 Fast by sweet seeds were like this too, but i wasn't a fan of the lack of potency or that particular flavor.
I use my homebrews seeds as filler. I plant a bunch of extras so i can trash the weak ones. Out of 5 breeder seeds i exapct 2-3 decent plants. That sucks, lol. Not growing 2-3 weak ass plants for 100 days to get a less than desired return. But, it's also hard to throw out "money". When you realize you waste so much more growing the inferior phenos, it's an easy decision.
this is why they should be cheaper or at least not be so chinsy with the seed count. These seeds cost a fraction of a penny to produce. Give us 10-20, not 3-5. Can't do shit with 3-5.
