Not to be rude at all to any of you that gave me your input, you all know much more then I do. I'm the type of person that needs to do something to learn..... So I put my plants 3' under the 1000w MH. They exploded!! They love it!! Under it for about 30 hours... they grew as much in that time as 3-4 days under the fluoro. One unrelated question; My White Rhino plants smell like weed already and the Big Bud do not, this is 16 days in. Normal??
