hi average im a novice grower too i bought a security light from a local diy store 40 watt hps bulb cost me £30 and it did the job. all i can say is dont get to caught up in all the technical stuff if you just want a bit of weed to smoke for yourself , of course the better the equipment the better the yield but i got about 1 oz of very very nice weed from my plant and it did me :-). hope it helps.
