That sounds like a nice loose mix, and should do well.
No matter what a change in soil will give them a horrible shock which means your growth will be stunted.. I've never grown an auto so I don't know how bad though. I've been germinating this seed for a little under 48 hours, the tap root has came out but only partially, it seems to be stuck inside the seed kind of doubled over, I'm hoping it comes out fine. If anything I'm going to plant it directly into the soil and hope for the best.
Put it in the soil now, if you haven't done so. Only bad things can happen to an exposed new tap root. I quit the wet paper towel method yrs ago.
Here's an easy way to cut your FFof so you can start in the final pot. 1st FFOF is very dense and should be cut by at least 1/3 with perlite, some cut it 50%. So fill your pot to about 5" from the top with the cut down ffof, and fill up around the outside to final level leaving a 6" diameter low spot in the center. Get yourself some non soil seedling starter mix without any food in it. I'm currently using Black Gold mix. It's just peat, perlite, and a little dolomite. Mix the seedling mix 50/50 with the cut down ffof, and fill the center of the pot. Start your seed in this mix and you're good to go. You shouldn't have to do anything but water for the 1st 3 to 4 wks.
i plant my seeds as soon as i see a tap root
After it popped out it seemed like it wasn't growing at all. I threw it in the soil, I hope it grows.
