Keep seeds warm / grow seeds using warm air from PC (power supply unit or processor fan generates constant heat).

A warm room with a lot of equipment making it warm also might help once temperature is high enough for your seed (38 degrees for some seed).

Bring plastic pot closer to PC base unit or hang at the back a little behind the PC (nailed to wall for example) so the plastic gets nice and warm and seed germinates.

The direct heat can be used to get consistent seed temperature (and then plant outside when it's nicer). Almost 38 degrees for example for Apricot seeds in tiny yogurt pot or smallest drink bottle.. so it's quite small and light (not much water etc)

CHECK YOU PC TEMP O_O
Use thermometer outside and in the soil :p

Of course I'm not doing any of this... "I'm just warming you up for the idea" :]

Oh come on entertain my jokes!
You're keeping your coffee warm already that way [aren't you?] so seeds are just a plastic pot away to test (and any fruit from wit seed from shop will do / can grow)!
