As this is your first grow, do as mother nature does ( and me too) put the seed in dirt, water ... not much simpler than this.....
I will actually soak a rapid rootter in PH'ed water ( 1/2 mil per gal of voodoo juice, B-52 per gal ), then place rapid rooter in a clear dixie cup placed inside a colored dixie cup, filled with
moist ( NOT WET) Fox Farm's Happy Frog soil. I will then take my seed (point down) and place in the hole 1/4" down, cover with a little soil. I will put them under 24 hour light until all have broke ground then flip to 16 hour light. I will use a small 10cc syringe to give them PH adjusted water just enough to keep the rapid rooter moist, they wont get there first REAL watering ( where the soil around rooter plug is watered) for a day or 2 after they have popped ground. I want the TAP root to seek out water so I give them very little water. I have VERY good germ rate 90% + last few runs were 100%.
Here are a couple of shots 2-3 days after puting them in dirt.
One last point, you could use a humidity dome (sandwich bag over cup) but I don't.
But what the hell do I know I am just a stoner
