Terrible advise.
Start flowering when they are a couple inches?
Its better to let it veg for at least 3 or 4 weeks, let it develop a root system, and some branches.
And you are talking about flushing when the guy got seeds in a paper towel?
Best advise.. (in order)
1. buy some soil and cups/pots
2. set up a couple CFLs
3. READ FORUMS, research better soils and lights while your babies begin growing.
