It's to late to get a decent grow going outside. Your best chance is to build an indoor setup for around $200-$300. If you want to practice outside and expect to get more seeds in by March, you could build a 3'x3' *(or bigger) raised bed. It only needs to be 6" deep. Shop around for deals on soil. Stick with organic with no added fertilizers. All the nutrients should come in the form of manure, castings, and compost. Over here on the west coast I use Kellogg Patio Plus. It's only $4 a bag and about 6 bags is enough to fill a raised bed.
While your at it, get some peas, and carrot seeds. Then divide your raised bed into fours. Leave one section of your cannabis plant, one section for a dozen carrots, and one section for 2-3 pea plants. The fourth spot can be your compost corner. The carrots will make a good hiding place for predator insects and the peas will add nitrogen to the soil, so you won't have to feed as much. The compost area is where you bury all the dead leaves. After your harvest, smoke and eat what you want and compost the rest in your special compost area.
Come March, start all over, except this time, you want to plant your cannabis seed where the peas where, and the carrots where your cannabis was, and so on. This is called crop rotation. It makes your soil last longer, prevents pathogens from getting out of control, and will help you learn all the skills needed to care for any type of plant. Doing it this way should also teach you just how little fertilizer you actually need. In most cases you can avoid fertilizing all together. Worst case, you'll have to spend $8 on an all-purpose organic slow release fertilize that will last you 2-3 years.
