seriously dude, if he listens to you he will be flushing 100 dollars down the toilet every month. 1 plant at 1,000 watts. you people love to waste don't you. bro go for 8 plant's per 1,000 watts at the least. it makes much more sense. rather then spend more money for less weed.
Yeah you go stick 8 six foot tall plants under a 1000 watt light...see how that works for you.
either youre too lazy to read entire posts or your reading comprehension is seriously lacking. Before spouting off like a rude jackass freakin read.
The OP mentioned wanting 6 foot plants..I laid out scenarios with which im familiar having grown everything from 150 watt light to entire houses running so much wattage itd evaporate200 gallons of water a day through transpiration.
With 8000 watts id personally grow 50 to 60 mid sized plants in active hydro like nft...which I mentioned above if you had read.
THE man askef about 6 foot trees so I gave him good advice on that having seen an uncle of mines grow with 25 six foot or so plants due to plant count limits...and he fucking kills it running one plant per 1000 hps with vertically hung 400 watt MH bulbs between the plants. You know canopy and internodes mean WAY more than plant count right?
