3 seedlings have monster root systems

they just started the 3rd set of leaves yet they all filled up a 1/2 gallon pot with roots(all 3 have em growing out the bottom so i transplanted em and the root ball was incredible! its about 3/4 of the size of my previous plants roots at harvest already.....crazy shit....is this good or bad? i'm thinking good but im also a little freaked out by it. plants are 1 week old about, outside with jiffy organic seed starter mix. i was gonna throw it away but i guess it might be good shit after all.

shit yea im going to get some to try myself its exactly what you want fill the containers up with roots its the engine that drives the buds

bump............

No doubt sir massive roots mean massive growth

i forgot an important detail.....at night i bring them in and put it in my 400w cfl grow box and when i get home at 6 am i just put em outside then when i wake up to work 10 pm just bring em in and plug in the grow box.
