Seed starting

What is the best substrate to start a seed in once it germinates? I plan on putting the plant outside in the end - I am not starting the seeds yet, I would just like to know what would work better - soil - rockwool - etc?

I would say that's irrelevant. What's important is proper(delicate!) handling of the seed and providing it with right amount of moisture and good temperature.
 
If I had to choose I'd use rockwool to give it a head start before putting it in the ground. I'm still newish so i could be off....

If going into dirt then plant your seed in Root Shooters, placed in a heated seedling dome. Or peat plugs but make sure any net or mesh is removed totally before transplanting. Claims of biodegradability are bullshit and your roots will suffer. Been there, done that, just this year.

Seeds straight in. No soaking in water, no paper towels. Drop the seed in and into the seedling dome. Make a dome with a reptile mat from Pet Smart. The small one heats a couple of 2 liter coke bottles placed as domes over plants.

and I would say the question is about substrate, not germination.

And I didn't say anything about germination. You asked about "starting a germinated seed" and I said that what you put it in is pretty much irrelevant and I stand by it.
 
Put it right in the medium you plan on leaving it in, nature will figure everything else out, don't go out wasting money on stupid stuff. Just plant it right in the soil and let nature takes its course.

Ok thank you. That is what I did for my clones(somewhat)

Use biogel,I use it in my chamber and I used it to germinate my Mary Jane and 3 out of 4 seeds survived, just have to keep it away from sun as fungus can develop. Then I placed the seeds(after the root can be seen) into jiffy pelets, and placed them in a humidy chamber 2pc box with an aquarium heater(set at 80, cuz it's fall) and heat mat, then later on I placed a 200watt grow light about 2-1/2 feet above it(just make sure it doesn't produce too much heat or can kill sprouts) but a low watt like 25 would be sufficient at about 2-4 inches(also depending where you are or if there's a humidity dome).. And yeah just make sure you keep the humidity low so fungus and mold doesn't kill the plants.(if it gets on the seed coat try to remove it gently without damaging the plant or stressing it too much. Hope this helps.

Crazy as it sounds, I love Miracle Grow's Seed Starting Mix. Fox Farm Light Warrior is pretty good as well. Although I've done great in coconut coir too. The most important thing is that it's light and sterilized. If your directly sowing in the garden, avoid adding uncomposted manures until the plant is mature. The heat from the composting can kill seedlings.

I don't use heat mats or do anything to pre-germinate them. I start my seeds in one gallon smart pots, indoors under a 200W CFL. I keep the lights running 24hrs on until they pop, then I switch to 18hrs on and 6hrs off. The heat from the light is enough to germinate them, even when room is 70*F to 76*F. Plus as soon as they pop they immediately get light, so they don't come out looking stretched and break from their own weight.

Lastly, I also wet the seed starting mix before I fill the container. Then I sow 1/2" deep and lightly mist. I'll continue to mist as needed to keep the top inch of soil lightly moist, but not saturated to the point where if I was to grab the container and squeeze it, water would come out. It just has to barely be moist. Mine all usually pop within 2-3 days. Here's a photo of my setup:

Very nice - So the miracle grow works good? I will probably use that as it is more readily available and I have no experience with FF soil. I have a 60w light for growing coral in an aquarium. Would that work if kept close enough with adequate aeration like a fan blowing between them and the light because it gets hot? Or I could maybe use my partners grow light for a couple weeks
the first option being by FAR easier than the second.
