germinating.

heres my problem.. well.. sorta problem.
this is my first time growing.. and i started germinating 1/5 of my seeds last week. i have 35 seeds in total, and theyre all bagseed from 3 different dealers. bagseed is just the seeds you find in bud right?? anyway.. i used the wet paper-towel in a warm spot method. anyway.. nothing much happened.
so i just got back from getting a small pot, around 5 inches in diameter and around 7 inches tall, filling it with the parents garden dirt, warm grass clippings, and that dirt with those little white foam ball things it it. i watered it with some of the water from my lake and put the seeds in, and left it outside. im just hoping a few will sprout.
is this the right choice to make?? anyhow, its too late in the grow season to turn back now.
two more questions: should i take the pot in at night so it doesnt get cold??
and: in my little seed collection.. about 1/5 of them are white. whats this mean??
thanks a lot in advance guys. ;)

your white seed could be sterile and dont use lake water it has to many "if's" like dead bacteria and living bacteria and maybe small amounts of some contaminant other then that i just suggest you read up on it i can't give to much advice i don't know from experience i have only dealt with store bought seeds but you should try to get a soil that is pH balanced

its ok as long as you get some mineral fertilizer, cuz the bacteria will break the fetilizer and it will balance the ph... but you should look for more advices

How long did you leave them under the paper towel? i had 15 big bud & widow seeds i threw in a paper towel and put in the water cupboard, i had 2 inch roots on every one of them 18 hours later, after 48 hours and a transplant i had my second sets of jaggered edged leaves appearing, i couldn't get over how fast the shit was growing! on a bad note my timer failed so the poor things fried in there 5th day.

some strains are different and take alot more effort for germination, you want to place some plastic wrap over your put and put it near a lamp e.t.c just to create some humidity, seeds/baby's love this!
