Its cold. I open it up several times a day. I get this same issue with the exhaust running too.

Looks like light beaching and burning to me from the light.

1.8 in jacks for me and I run around 30 c with leds and warm nights. Heats your friend but it drives costs up. Al most better off running an Hps for heat and light. Leds aren't any cheaper to run.. good luck mate..

I'll go with 1.8ec for a week and see if that helps. The runtz are light green in the center of the tops so they look like they need more N??

I added a bigger oil heater that takes up the entire center of the 4x4 tent. I should be running this fce4800 in a 5x5 but the ceiling is too short. Light has been low but since I got the temp up and humidifier going I set it at 75% and I am at 2 ft over canopy. I will try to get some leaf temp readings. I will see about adjusting for night temps. They have been in the 60F range.
