possible light burn help me tanx
Nursestarted grow question 6y ago
I have two lights, spider sf 1000 and viparspectra p1000. My plants have burn marks. I do not know if it is from lights or fertilizers. I now keep them 18 inches apart. Can anyone tell me the light distance table? How far should they be now?

Light height full power vs dimmedHi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)

Very technical question - LED wattage vs actual power usedMy LED is a Phlizon 600w but the power draw is only around 97w at the plug. Perhaps a silly question, but is my diary entry supposed to be 600w or 97w? Looking at other diaries, it looks like yield is expressed as weight/watt and want to be consistent.Other. Other

Light cycle change?Quick and easy one for you fellow green fingured people. I opened my tent to a wonderful growth overnight. As I was doing some more training I had this wonderful surprise. (Ref picture below)
The question I have is they are all autos currently on 18/6 light cycle should I switch?
