noob grower. need some help if possible

I recently bought 12 feminized "Mazar" Afghan seeds. i've germinated 6 of them and have planted them in 1/2 gallon pots untill they reach 6 inches tall, then i will transplant to the outdoors. I'm using a nitrogen rich soil and watering once every 2 days, because they have been staying moist untill after the first day. i have a few questions. they are pretty green and are about 4 inches tall. Should i wait longer than 6 inches to take them outside? how often should i water them? will pestisides harm the plants? and any tips or recomendations that you have for me. thank you for your time.

I'm not gonna tackle all your ?'s but it sounds like you are over-watering already. Make sure the soil is dry 2" down in your planter, AT LEAST.
It's much easier to fix under-watering than over-watering. Little seedling plants don't use much water. It won't die from thirst overnight, but can become a loss if kept wet.

ok, i will definately take your advice scince this is my first ever grow.

that depends on where you are (when to take them outside, depends on light cycles). water as fishy said, it depends on the pesticide. make sure you mix up a damn good medium for your outdoor set up, put something up around it so that wind and animals etc can't get to it, don't neglect them, pay attention to the weather and to the area surrounding them, watch for bugs, if you get bugs, use bugs to kill them (mostly). don't forget your bloom nutes, learn how to sex, be patient... work hard .

and read a cannabis horticulture book!!!
