lol if i was growing for money i sure as hell wouldn't make a title saying growing to sell lol. Do what all the other arsehats are doing and leave you shit half cured, sugar/silicone covered and use a strain that makes huge yeilds. As a noob if i was going to do it i would choose 2 x 600 hps over the 1000 or use a light mover on the 1000. All the info's on these forums, read grow logs find out what works best and since your for money weigh up medium, nute, hydro type and effective for your grow room ect. Since your growing for coin you wanna keep your mouth locked tight as commercail gowing will more then likley see jail time, its ganna be hard to argue you smoke 2 pounds a month lol. How the hell you would get 2 pound a month off a 1000 hps has me stumped even with a light mover and multi crops under it? lol ill be happy with 150grams off my 600hps over 4 months
