few questions, root hormones, and root space.

ive been reading a lot about growing, ive germinated my seeds, i used about 4 seeds that were getting the white stem. i used tweezers to put them in a pot.
(heres where i think i went wrong) i put all 4 seeds in ONE pot. my plan is to have one plant. i figured i'd let them grow, then transplant. is it going to be a problem transplanting all 4 of them to different spots? im transplanting into the ground.
anyway, i planted them 4 days ago, they are about 2 cm tall, and very green. i water every other day with a spray bottle. are root hormones a good idea to put into the bottle? also i read diluted urine is good for plants?
yes? no?

that wasnt a good idea. they should of been in separate cups. I would recommend that you GENTLY transplant them into separate cups. and make shure if the cups are see thru then tape them, so that the light dosnt come thru to the roots....remember u want to transplant before the roots get to long. oh dont give it any nutes or any substance...just water for now. u will kill them if u do the diluted urine or root hormones.

root hormones are for the roots not to be sprayed on. Piss is not good for your plants.

read some books and don't
take your friends advice....
seperate containers... I made that mistake, it's just easier...
get some rock wool cubes. I put them (sometimes) in dirt outside...

I did the same thing a few weeks ago, but if your soil is loose, it will be easy to separate the youngin's.
