>>166Really sorry, been having major issues getting in here.
That plant is stretched out to shit! What light source are you using? If it's LED move it closer for god sake. Failing that at least move that plant to a window.
How deep did you plant the seeds? You really don't want to go more than 2cm. If they are deeper, don't dig them up, they will come up but will take longer.
Your room temp should be fine, although a little low. Try moving them nearer a heat source. You really should buy a cheap thermometer to keep in there with them.
Moving them outside depends on your night time temps. You are probably better off germinating indoors anyway.
Warm them up and when they have germinated move them into a sunny spot.

Hopefully the others will all come at roughly the same time, assuming you put the seeds in at roughly the same depth. Apart from the stretched plant you don't appear to have done anything wrong.
Good luck Anon.
