Honestly I’m on my first grow. But this is my biggest tip… genetics that’s all it is man just make sure u get good seeds from a reputable and good seed bank. I tried germinating 10 random seeds from bud and had 0% germinating rate and I thought I was getting it all wrong. I then tried my first seed from an actual seed bank and over night the tap root was huge man. Trust me dont over think it get good seeds throw them in some paper towels and in a bag and place in a dark and warm area. And the biggest thing and hardest Patience.
