I lost 3 seeds in germination, so i have 20 plants instead of 23. it all is random really, I started from baggie seeds so the strains vary greatly. ifyou germ. correctly you should do ok. but always figure on losing 1/4 anyhow due to not germinating, bad strains, males, hermies, etc...I lost a plant today, just went belly up on me. died right next to its healthy sisters, can't figure out why, but I have more so am not sweating it.
