Well i was just told that a 250 watt HPS. Would be to much heat for the small rubbermaids that we have right now. I can see what they mean. so for the time being We have to use cfls for light. We are going to try to get betwwen 12,000 to 15,000 Lumens in the boxes. If our exhaust will handle it, possibly more? We have some 42 watt cfls. We were going to initially flower with these anyway's in the beginning. So we will try to do it this way, this time. Cabinet is in the works, but is down the road, probably late December, but we will be 110% more prepared with a sun system yeild master, Then we will add a 400 HPS. Thanks for the input, any more info is alway's appreciated. We will post pic's soon.:thumbsup:
