I have to take back my comment earlier about it not being worth it for a frist grow, i found a place that has a 600watter dual spectrum bulb, thats quite cheaper in the long run than a 1000w, and a 600watter is the most efficient HID bulb. That makes it very worth it for personal grows since 600watts is a more reasonable than 1000ws in the end
A cheap way to add more spectrum without a large investment, id say $40 or less in the end. There are companies that sell basking lights for reptiles and birds, these lights give off about 40%(give or take some) of UVB that the 600 MH would. There is one that i found at PETSMART that is a halogen style floodlamp that has full power at up to 3 feet from the bulb, so add one of these and i bet itll do the job just as well as a dual spectrum, i plan on experimenting with UV rays and growing. There was the thread in the advanced growing forum that is abso-fucking-lutely huge about the whole UV debate, but most would agree UVB is a welcome addition to any room. Just take care to not look at the light, as you may damage your eyes, wear sunglasses(youll look cool) or turn off the UV light when in the room managing your babies.
First off Commercial is growing copious amounts of high grade weed for sale.
Second, in my own opinion a 1000watt lamp is not a good choice for a "first" grow, if you have prior experience, then id say give it a try. A 1000watter can be way too hot and make your room temps soar if you dont have adequate air exchange(either air cooled lamp and room or AC), plus the 1000w bulb isnt that cheap.
Third, if it is a smaller grow, as you say it might be, why get a lamp that covers almost 50ft2(7'x7'). Why not just get a 600watter and save cash and electricity.
keep on keepin on we are all most there people, cannabis has came a long ways since 1970.
