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?

Grow Lights
Is it okay to use an LED Light 1000 watt (4x4x80" tent) & a UV Light 1000 Watt in a 4x4x80" grow tent for 3 plants. I want more light, I have plants growing slowly so I'm hoping to adjust the amount of light I have would speed up their growth. LED is white spectrum & UV blue-veg

Booster light did not turn off during night time

Hi! I have just changed to 12/12 bloomtime for my girls. I have a wifi-cam installed so I can check in on them when I want. It has night vision so there are a few red dots(led) from the IR. Can they cause trouble nighttime?

ViparSpectra XS 1000 (x2) vs. HLG 100 RSpec (x2)
Thoughts on VS XS 1000 (x2) vs. me buying HLG 100 RSpec (x2)? They'd go to either side of my HLG 225 in a tent that's 2.75' deep and 5' wide to 'fill the wings' more evenly. Thoughts on build, safety, quality & heat? HLG 100RSpec:0 / XS1000: (on sale this weekend)

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

For folks with Mars Hydro TSW 2000 experience. What dim did/are you keeping your light on during weeks 2-3? I have done research and looked at MH data, but I would like tried and true experiences. Current dim is set to 2 notches below 50 at 18in. Thanks.

Подскажите., почему во всех гайдах и пособиях пищут что автоцветам нужно на цветении 500mmol/cm2 а фотопиродным 700, в то время как реально под солнечным светом растение в ауте получает 1400-1600. Почему не дать столько же света растениям в индоре?

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !
