No, have lots of recent pictures of my grow at the URL in my sig Knowm. Havent noticed stretching and haven't had any of my friends who are relatively in the know how say stretching was going on either. I guess the problem could be easy to fix... perhaps I can set the d/h to a higher relative humidity, then it won't be on as much heating up the room. Or I can run my exhaust fan (for now it's only on when lights are on) I could run it maybe 15 minutes out of every hour to see if it brings the temps down. It's going to make the d/h work alot harder though. Any other reccomendations knowm?
