blackberry, critical and humboldt

starting my first grow log. veg room is 3'.5"w x 7'.5"d x 7'.5"h. flower room is the same. veg room is a combo of cfl's and 4ft tubes. currently i have been trying to get some white widow going but have come up with nothing but males. so i dropped 10 more ww's a few weeks ago. hopefully i will get a few ladies out of that bunch. i have 1 bush(im fond of lst:D) i started from a clone i took from the summer outdoor run in the flower room under 1 600w hps. it will be ready to chop in about 2 weeks. by then i can move the ww's to the flower room for sexing. i want at least 1 mother form them. now for the stars of the show; 2 advance seeds critical feminized, 1 ch9 humboldt feminized and 1 sativa seeds blackberry feminized. started germing in paper towels about an hour ago. i will start them out in a vermiculite/ perlite mix for the first week or 2. that will give me time to prepare my soil. i have used mg in the past with good results. however i just found a hydro store a few hours away from me so i plan to make a run by there and see what i can find to give a try. i do plan to use these plants for mothers so i was thinking of using soil for them. after i start the cloning i have a few other ideas i will put in the game. ventilation is not a problem. i have been doing hvac for 17 years so i now about air movement. i dont have to worry about the smell as my closest neighbor is a 1/2 mile away and the set up is close to my animals so any one that comes over will never know. as for co2 i have been doing the home mix method but im not sure it is adequate for the 600w hps so i plan to get a tank set up with timer soon. i have had grate results with foxfarms nutes so i dont see a need for a change there. i try to keep my runoff ph at around 6.5 and havent had any troubles . in fact the only real problems i have had is with grasshoppers and humidity outdoors. them bastards will eat up some buds. and last year we had lots of rain in the fall and i had some fat thick buds that ended up with a lot of rot issues. i just ordered a new battery for my camera so when that gets here i will post some pic's. if anyone has experience with any of these strains feel free to give your input.
