welcome!! when i started i found that a 250 or 400w hps worked best as hps will grow/flower and provide heat in colder areas, sheet a space or get a tent, i started with a 250, small sheeted space, 5 fem autos and the cannabis bible(check my threads for pdf of this on this site as well as other good reads, to start i would suggest normal soil,250 or 400 hps, 5 fems and soft feed, as you learn the plants and enviroment then use more/different lights,look into hydro/pebbles etc, but ease to start a 250 or 400w hps as these can be got complete with bulb ballast and shade for £65 quid on ebay, some pots, good compost and 5 only, as you learn you will get to know tricks! check out the growers bible here

its all about experience, hps are the cheapeast way to start with soil, i still use this set up, tho i use 4 400 now and a larger room, but thats from experience, know your plants first, watch then , research any issues on here, anyone will help we are all here for knowledge. but a cheap hps, sheet and seeds for 5 will be around 100 quid set up, expect 1oz a plant if chosen correctly, diesel ryder or any jointdoctor good starters as they are stable, need little attention and can take abuse if you get it wrong without dying!!
