first grow help needed through out

hey everybody this is my first grow ever i dont know what kind of plant they are. i got them from some weed i smoked about a year and a half ago. im not expecting this to be amazing stuff. im treating this as strictly a learning experience before i go out and spend money at a seed bank. i want to get the most out of this grow so help form anyone through out its duration would be great. i will continue this thread with updated pics until it its done.

my setup
i have four plants in half gallon pots, with two 18 inch, 15w Florissant plant bulbs that put out 510 lumens each. and i had two 100w hora solar bulbs that but out 1300 lumens but one burned out 2 days ago and i need to get a new one. the lights are probably a foot away from the plants. the plants are sitting in a clean 25 gallon fish tank (makes it easy for watering). and i have four and a half feet of ten foil 360 degrees around the closet for when they get bigger. heres the first pics. i germinated for 48 hours then planted them in jiffy germinator things where they grow for four days. then transplanted them to the half gallon pots where i put miracle grow organic potting soil in them (i want to stay all organic), they have been growing for 5 days i have watered them twice.

they seem kind of small to me for 10 days let me know what you think im going out now to to exchange the bulb that burned out it was bran new only on for 25 hours before it busted!

ok so i got the second bulb back and after a little research i moved them with in six inches of the plants cause they don't put out a lot of heat but a little.

Looks like mine lol.
