As for cheap seeds to practice on, I'm also going to explore am ideal medium that works best for my map coordinates, I have no idea what to buy for indoor, although I am intrigued, (not discouraged so I'm following a calendar about my ideal zone for outdoor. I might've missed the boat and it's too late, but at least I can practice for next season.
So my point is, should I be using autoflowrt or feminized or crapshoot and pull males? Can you get inexpensive auto flower? What about for hydroponic? I'm so into this as a hobby and personal use make edibles and smoke my higher grade. There'such to know! It's so satisfying when any plant grows.
