Ah-hah, a question i feel like i can contribute to.
First thing you need to know bout strawberries seeds is their hella tiny
like the the top of a sewing pin. just a little fleck- so super fragile n can blow away n the wind
This is the sure fire way I would grow these @ work(Smith&Hawken) to sell as seedlings ( noone like starting these from seeds)
I would start out with a tiny cup size plastic square pot. (cheap nursery plastic design w/ drainage holes at bottom)**Party cups may work here 2
Fill it up with your dirt. (you can flatten or make a little mound, it's up 2 u)
Moisten your dirt
Take a pen , chop-stick , knife whatever and just make some random pokes &slits on top
for the seeds to fall into.
Pour some of the seeds out into your clean sanitized hands . (not directly on soil, it could all seep out)
And then sprinkle some sparsely across, no need to completely layers, just pretend your seasoning some food
Then add a quick sprinkle of water too, to welcome home the seeds.
Set this on a seedling heat mat. Put your dome on it. Let it sit for a day or so.
Than they'll start to grow , like little-bitty green hairs. Be uber-careful with them.
Even a fan can still blow these guys away in there first days.
Keep them in your dome till they get strong- You'll know when the time is right, motherbird
Basically they like it real humid and they're really ducking fragile .
Hope this helped someone
Growing plants need time and utmost attention..may it be for indoors or not.
