Temp's run between 80 to 87 degrees. We just put a new fan for our intake that seem's to be circulating better, our outake is working great. Could the leaf curl be from possible to much water? We had to water a bit more than usual last time when we were doing the LST placement. Also another question we wanted to ask. when the light's are off during 12/12. and due to the door having to be closed thruout the day. Is it ok to run your fan's if it's to humid in the boxes? Thank's for the help Image Reaper & Killerweed. Have a rep on us.:thumbsup:
