Time lapse under HID lighting
Demosthenese
started grow question 4y 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 spectrum during veg and bloom periods
I have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?

raise lights during stretch?
Should I raise the lights during flower stretch to maintain the same distance from light source to canopy? I notice that my plants continue to get taller than most. I know the stretch is natural, but I'm wondering if constantly raising the lights with growth is the right approach

UV LED slowing down growth? Sorry previous question without the question!
The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

Can you use a 450 watt white led light to start seedlings? If so what distance should the light be and when should I make it closer? The reason I am asking this is because I don’t like transplanting autos as they are fragile to transplanting from what I’ve looked up

First questions about light
Since I'm using a chinese 50W led grow lamp , what is the right distance from the plant? I'm doing 18-6, but since she looks little for her age, would be useful to turn 24-0? many thanks for your help
