ok, not to just be an asshole and make fun of you.... this is whats up.... if you have a plant, in veg and you veg it to lets say 1ft tall.... once you put it in flower its gona stretch.... to 2 to 3 feet tall... now if you just have some cheap clf's your not gona do shit... reson being... the light from the clf only penatrates a couple inches.... meaning if you have a plant that is more then 6 inches away from your clf its not geetting the light it needs.... the lumes go so far then die out... like a 1000watt hps can penatrate a canapee about 3ft... after that the light is pretty much useless... same thing with a 600watter... maybe it dons't penatrate as much.. like 2 and a 1/2 feet till you start getting light degradation... now if your just using hows lil clf's your not going to get shit..... your plant sounds to be big enough to give you a yeild from what you saying... but you have to remember this... wattage times sq foot = yeild...
on avrage you will get 0.7 grams per watt of HPS light you use to flower...
sooo if you have a 1000 watter you would get about 700 grams.. thats a little over a pound and a 1/2 considering you know what your doing.. now you can get more or you can get less that depends on your setup weather you have co2... what boosters you use.... on avrage if your a new grower using a 400watt hps light in a closit space 4ft x 2ft thats 1/2 a meeter you will get about 6 to 10 oz... ... i just relaised i forgot to tell you about the space part of the watts equation... your light will only cover soo much area... like a 1000watter will cover a 4x4 area.. a 600watter a 3x3 area.... so you do watts by squair foot. like my area is 10x7 that gives me 70sq foot... i have it plants wall to wallll... i also have 6 600watt hps... so thats a total of 3600watts now devide that by 70 cuz thats how many sq foot i have... it comes out to being around 51 watts per sq foot.... i expect to yeild around a pound per light... so thats 6lbs total... wich is 448 x 6 = 2688 grams... devided by 3600watts that gives me 0.74 grams per watt... now you see what i am talking about... i have a 7x10 area... covered by 6 600's at 51qwatts per sqfoot and i'm expecting a yeild of 0.74 grams per sqfoot which works out to 1lb per 600 watt hps lamp...
hope this clears up some things for you...
my best advice is get a real light.... if you want real pot you need real light hats all i have to say
