First read as much as possiable. I am no expert but . good soil , good light, and good seeds is were i would start. I believe in using hps and mh from seed to harvest. good fox farm soil. good nute in moderation, And good beginner seeds like northern light , ppp and such look up the attitude seed bank. bag seeds are ok to learn , but messin with what you dont know you have kinda stinks. Everyone has there own methods .So keep it simple. Dont over water and dont try to speed things up by forcing nutes.read grow faxs that is you best bet. And last of all be paitient near harvest . most newbies harvest early..... Also good air ventilation wouldnt hurt..good luck
