Thanks bonbon for your help, I'll try that. I don't exactly have the "perfect setup" for my growing room. I do have a small fan running all the time, but don't have the fresh air coming in when the lights go off because of the temp being too cold. It is a nft system and I keep the water running all the time. That worked before with my other plants but they were from clones. All the instructions that I got with the system said that I should keep the water flowing constantly. Thanks again, I (probably along with alot of other people) really appreciate your help. Willow
