30 green crack clones

hey so i dont have too much to say this is my first grow journal, 2nd grow. last time i grew 3 this time im doin 30. i am runnin 400w hps, 12inch wide pots (no clue how many gallons), promix as my medium, a house fan blowing air around a can 50 carbon filter and a vortex fan. this journal is open to comments i willl probably be updating once a week, possibly more and ya hope you guys like what u see pc

damn 3 to 30, you get to know the plant the first time around then the 2nd time you do it proper. how long you plan on vegging for? how does gc grow, is it pretty short? i just picked up a clone you have any tips?
