dear god,, its vansterdamn you should be able to find seeds somewhere,, i think you just need to look harder...... supplies for 2-4 plants? well if you are going HID (HPS or MH) i would suggest at least 400 watts of either to get sufficient lighting. depending on how cool or hot the area you will be growing in (and the size) you may need a cooltube for your bulb... ventilation is always a must and should be judged on temp and size of the area... if it is a closet type grow you can buy these 4" 115v fans for like 10 bucks at radio shack or some kind of liquidation or surplus store. You will need at least two of these,, one for intake and one for exhaust and you may need some ducting to get the hot air away from the plants.
soil - try to get some store-bought sterile soil with some pearlite in it. some varities will also have humus and compost for added nutrients,, its a good thing... and obviously a pot.. or 4 depending on how many you plan on growing.... get some nutes too,,,, nitrogen is a must for veg state but you wont need it for a week or two after seed. make sure to get something for flowering too,, something high in Phosphoric acid and potash.
and it wouldnt hurt to get some litmus paper for pH testing... you want ph around 6.5 for veg and 6 for flowering
