TRUE OR FALSE!?!?
True or false?!?! LED has a longer flowering time. LED needs less nutrient. LED has a more spread light output. After reading to much about it, I would like to know what GD community thinks. 🙏🍀🍀🍀🙏

I don't really know when to switch the veg light to the bloom one... the manufacter manual says to turn on both lights in pre-flower stage. What do u guys think? I also lowered the light (200w output) from 67 cm to 60, is it ok? (LED Viparspectra V 450)

Danger of Humidifier
Good morning everyone. So I've recently set up my new TS1000 and I'm wondering is humidifier dangerous for LED lights? It's directly under the light 60cm. And how can I regulate the temp in the room without new equipment? It's too high at the moment.

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.

Currently my lights are on a 18/6 schedule, from 6am, until 12am. I want to change their light cycle to start at 4pm and turn off at 10am, so the heat of the light balances the chill of the night. Whats the best way to do this, without triggering flowering, or stressing them.
