I may be the least experienced grower on here. I have only been growing a few years, so others on here would be far better at giving advice I would guess.
I try to include something from Katsu every run because I find the stuff I get from him to be reliably strong. Bubba's Sis was my second grow and I have been hooked since.
I also have liked most everything I have grown from Madd Farmer. I have grown a couple of strains from Dirty Water Organics that I really liked a lot. I have one of his to pop stiill, Katsunana.
Brandon Rust has some interesting stuff. Blueberry Train Mac grew differently and had a hard to explain nose. I have other seeds from him but have not popped them.
One of the frostiest and stinkiest strains I have grown was Offendo from James Loud. That one or Finishing Move had to be the frostiest.
