Hey Garden Knowm, I have my lights come on at 5 pm and they turn off at 11am. I think my soil is around 7, but I havent tested it yest because I just got outta knee surgery. They did a acl reconstruction and fixed my miniscus cartilage. I will have my nuted water at a ph of 6.-6.5. Last time I checked my water with sum superthrive it was at 7.0-7.2. I was a light greenish color.

I have a fan accross reflector to remove any heat, I have a smaller fan blowing on the plants, and a third one in the bathroom ocillating fresh air in and hot air out, plus I have air conditioner running during the daytime to bring temp down to 80-82 degrees when air is on. It seems like I have to water plants more often since I have switched to 400w hps. I give the plants about 12-16 oz each daily except my youngest plant. I will be putting them to flower in 3-5 days and I will need to tie down 2-3 of my plants if they turn out to be females. They all look really good compared to my last 2 I had. Thanks Garden Knowm!!
