A lot of cheap (and or free seeds) to be had, just have to find the right (non greedy) breeders'... KCBrains, Nirvana/Positronics, White Label, The Dragons Lair', Seedsman/World of Seeds, Mandala, etc. etc. etc...
No need to spend tons of $ on seeds, most of those companies are ~30$ for a 10 pack, I hear DL' gives them out for free in almost all cases :cool: you just have to find a way to get a hold of him' ;)
Don't get to discouraged on your first try, we all make mistakes over the years/grows and over watering is one of the first bad habits to be broken.
Take it easy,
Azh' ;)
