i agree. sure cfls are cheaper (to buy initially) however they will cost OP more in the long run as he'd be averaging 70 lumens per watt compared to 140 lumens per watt under HID (hps/mh) lighting. Only downside has been mentioned: HEAT. My first grow was CFLS only through veg, by the time flowering came I bought my first hps and never looked back since lol.I don't think having an hid over cfls is that complicated you dont have to be an expert just plug it in. But as stated there expensive if you grow on a budget. But I personally like to spoil my plants and not short them on anything. But to me it's worth the extra $ for that extra you get in buds.
OP the heat should raise the temps by about 10 degrees give or take mattering on how good your ventilation is. Thats why fans are especially important when working with HID's. the fans can keep your plants cooler allowing you to get the light closer to the tops of the plants versus growing without fans while using HID's.
Your bill will be similar no matter what you use 500w of cfls ( ie. 100w per plant x's 5 plants) or 400-600w of HID. The only real difference is you'd be half as efficient with cfls versus HPS. so in reality you'd be paying less a month for the HPS in the long run if that makes sense as you'd be using almost the same amount of electricity for half of the lumens.
i hope i didnt confuse you but sirlancealot is 100% right imo. spring for the HID's and it'll pay for itself by the 1st harvest versus if you choose cfls.
imo cfls are good for vegging, clones, side lighting, and small micro/stealth grows (ie. pc grows or 1-2 plant grows) but for 5+ plants i think you'll be happier with HID overall. more bang for your buck.
Remember OP the bulb of the HPS/MH will need to be replaced every few grows even if it still works as the lumen output on a mh/hps bulb will decrease after a few grows (matters on how much you use it). i personally replace mine after 2-3 grows but i buy cheaper hps bulbs so it doesnt matter to me. they can get as high as $150 per bulb if you buy the expensive ones but you can easily find HPS bulbs for $20-$50 brand new if you go to the right place. just thought id mention it so you're not shocked down the line.
