hello everyone, im a friend of swinophobe, the one in charge of all the  technical things and lights, hes more a green thumb than me and im good  with nothing more than wiring and specs, however thanks to everyone  here, all the guides and other grows, im picking up quite well and its  all so interesting, makes me want to start now.
unfortunately i cant, theres a lot of complications which im worried for and i probably shouldnt be. 
we  live in an area that doesnt have much resources and if there are any  they are probably overpriced for our college student pockets (which is  exactly why we couldnt afford led as much as they sound grand). if i  could i would have made my own compost, which a roommate already does,  but i dont know if eggshells, teabags, veg scraps and other organic  things chucked into this compost is any good.
 we ended up  settling for the only soil we found that isnt an alkaline and made for  petunias or roses, a bag of john innes seeding compost, luckily  swinophobe happened to stumble on some perlite from a pet shop, we have  yet to check a few other shops in the area and if we happen to find some  coco coir we might be considering it. other than that the only nutes we  found locally yet are a westland brand, the best sounding are bonsai  1.1-3-3 and tomato 6-3-10 + micronutes. i already happen to own a indoor  5-2.5-7 plus trace elements, but it seems way out of balance.
what do you think of this soil and nutes, is there any other common soil which would be better that i might find?
should we bother with a metal halide bulb for the first 2 week of veg? ill be going with a 250w hps and a non adjustable ballast
giving thanks ahead
