Ok, I am getting ready for my first grow and need some pointers. I have a metal halide unit with a 400 watt bulb, also have a 175w bulb. Can someone recommend what type of soil and nutrients to use? I'd like to keep it cheap, but decent. Things I can pick up easily. Also can I use the MH through the whole process? Should I just put the seeds in the planters to start them off? That is how I've always done it, if not is there a better way? As far as the MH bulbs, could I use either one's? Would the 175w bulbs work good if I keep them close? Any help would be very much appreciated.
