I bought one recently with the help of their Grower Feedback Program. Will be starting my journal shortly. I have mine in a 4x4x4 cabinet. Temps stay around 75F with carbon filter and 130CF fan. I could probably cut a larger intake to get the air moving but ambient temp outside of the cab is still a little cold.
I started a White Rhino from seed and it seems to be responding very well. Much better than the 200w CFL's I used before. I'll try and get my journal started in a couple of days and you can see for yourself.
