Time lapse under HID lighting
Demosthenese
started grow question 5y ago
How do people do time lapse with hid lighting? Do I need to set timers to turn off hid, turn on fluorescent and then take the picture? Is there a filter I could buy that eliminates the horizontal scanning lines?

Light burn
2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

Low Humidity and high temp or high humidity and low temp?
Do you think it’s better lower temp and higher humidity (like 27 degrees c and 80 % humidity) or higher temp and lower humidity (like 29 degrees c and 60 % humidity)? I’m just waiting for the humidifier but in the meanwhile I have to fix somehow. Thanks!

Reverse flowering time
could I reverse the time when putting into bloom and switching from a 12/12 program? I could turn on at 00:00 and turn off the light at 12:00, because honestly I keep them on during the night and I turn them off at noon and I would like to do the opposite, can I?

My timer on 18-6 broke and i'm not sure if the girls had 24 hours for the past couple days... by putting them back into 18-6 will that trick them into flower? Hope not. Thanks :)
