I sure if you had the curtains plus a very powerful fan plus AC you should be fine you should run some test before putting your babie underneath 1000W

google the LR-1000 that hood is the best money can buy...........
invision... That hood is almost as big as my grow area.. thats really a life-time investment..

Consider the fact that MJ fries at 10,000 foot candles so no matter what hood you buy you will need to keep it at a height that the plants won't burn at. So consider your budget and add in a light meter so you can set you lamps at the proper height.
If $ is a concern I say go cheap ans set your light lower with fans blowing off an heat that the air cool hood doesnt eliminate. 24 inches is as close as you want to go per Jose Cervantes.
The LR-1000 by bell lighting is not big at all!!!!!!!! It is powder coated to eliminate the need for an internal reflector that PL uses.
I am actually looking at 3 600 (1800)watt instead of 2 1000(2000) watt lights. they can be placed evenly and since I am pruning and growing 2-3 main colas It should yeild more...
Love to yaz alz -Jay
do you have a light meter? the glass will cause you to lose less than 1% of the light the bulb puts out.Quote:

Caljay & Justa... thanx for your imput....and yes I have a Apogee PAR meter and I'm trying to achieve around 1100-1200 (µmol m-2 s-1) in a real even pattern for single cola per stem sog (an old moderator at CW was able to get 1/4-1/2 oz buds in 60 days... ten days veg from rooting)... and my records show u can lose up to 6% (usable light) with even thin pyrex... the luminarc III for 128 bucks delivers a nice squair pattern.. and according to the tests... (with a 400 mind you) the most PAR... I haven't seen a similarly priced hood that can get that much light on the 3x3 target... and air/water cooling is not a practical option in this situation anyway... sorry if I wasn't clear at the beginning of the thread....

for 3x3 if the heat is not a big prob go with the LR-1000. a cooltube gets rid of up to 90% of the heat the light produces so it's the best choice if there are heat probs but they usually aren't the best reflectors. i had excellent success with mine though.
That hood cost how much?
FC
i'm not sure how much it costs. a friend of mine has 8 of them for his grow and he loves them. i have heard that from others as well and that's why i suggested it. i haven't used 1 myself and i'm not quite sure where you can order 1 from. maybe someone else can post a link or something.
