the root of my love for F1's is my own lazyness.
They dont need a hand held. Shit i could prob toss em in a flood plane and come back and harvest weed in fall. no other steps necessary. Theyll surface germ on soil, find their own footing and stand themselves up, ive tested it in solo cups anyway. Its really cool to see. They move all the time, and almost make decisions for themselves while growing. Im constantly pruning and adjusting/opening up all my plants but the F1s. Ive done basically nothing but hoe in some goat shit and water them really.
And F1 isnt a strain, its just a first generation cross of two completely unrelated lineages. I just named it peaceblaster because its a good weed name, all the plants have has super happy smiley highs, and so people know what plants im talking about. F1s happen by accident sometimes, that's what most of the free fem seeds are. Accidental fem F1 crosses usually. If you dont keep the right plants around you cant stableize those, useless for breeders, great for advertisement ;) ..... Every seed made will produce a unique, and often excessively vigorous phenotype that will usually grow faster, get bigger, be more potent, yield more, and flower quicker then either parent. Some will be better then others, but tbh, ive not run an F1 yet where nearly every phenotype wasnt more desirable in one way or another then either parent. The further from inbreeding i got, the more impressive and unique each individual plant became.
My peaceblaster is half columbian land race, a 14+ week plant. Ive had heavily sativa dom pheno from these seed that finish in 7 weeks solid and have also been the highest yielding, and most enjoyable flower to smoke ive honestly ever grown.
This where the "youd have to fist fight me and win to get me off this bandwagon" comment comes in.
Imho, once you nail your growing technique, genetics are the single biggest factor that remains. Tbh, at that point, its all that really matters anymore.
