Stink bud is a legend around here. This here thread in the hydro section has been going since 2008.
Outdoor growers are heading inside now so I thought if might be a good time to start a thread on how you can harvest a pound every three weeks from a 7x8' closet. I'll take you through my process from start to harvest. What is different about my system vs. others? 1) 3 separate Aero/NFT...

We ran aero rails for years and thought they were great until we lost power for a week one time and I ended up going full organics. Anyway to answer your Q there’s a few ways of poppin seeds into rock wool. Clones are preferable obviously but seeds can easily be done if you give the love & attention they need to get started.
The way I prefer is to first soak the cubes for a few hours in ph adjusted tap water… you can add a drop of lemon juice to a cup of water and that will be pretty close to 6.0-6.5. It should be moist but if you squeeze the cube lightly no water should drip off. Place seed into the hole and drop the cube into a ziplock bag until it sprouts. Blow in some air and seal the bag. Once sprouts emerge you can take the cube out and keep it moist by spraying 2x daily with a hand mister under low light. Do not try to put seeded cubes into the aero system until roots are pushing through the bottom.
