i guess i messed up using a 1000w hps in a 3x3 grow box the bottom leaves on my plant dried out real bad. couldnt get the humidity up was set on 30% and wasnt going up. i then put the 400w mh in the grow box and they are coming back to life again humidity is 50% now. i guess i could have used the 1000w hps in a larger space , than i would have to kick grandma out of her room. lol
