Quantum board lighting question

MulzinMostarted grow question 5 years ago

What setting should I be using on my 240 watt quantum board LED light? I currently have it at about 1/4 strength and 24" from the plants which are 2-3" tall at the moment.

So 60w More light past seedling stage I would default to the 30w/sqft rule So a 3x3 - 9 sq ft = full power 2x2 - 4 sqft = 120w (half power) Just an opinion but they look like they could use a lot more. Walk it up IMO

Led Grow lights I have a viperspectra xs4000 light 480 watts I am running it at around 25% on the dimmer switch and my lights are about 24" from my canopy. I've noticed some of my pistols wilting and looking stressed. Should I try to move my lights higher or continue dimming them down more?

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?

How can I prevent these light burn issues?It seems these Mars hydro lights are not so great. This is my third grow and having the same issue every time. Red stems where they are exposed to light. Yellowing leaves. But when I move the lights further away, stretching is very bad. Should I just get new light?

Increase light hours autoflower My autoflowers are 6 weeks old and showing flowering signs. Can I increase the number of light hours from 17hrs to 20/22/24hrs? Does it cause light stress and can trigger vegetation or make it hermaphrodite?

Affordable but good growlight for small space I'm looking for a cheap light to grow one plant, the current one (90w) have just doesn't have enough juice so I'd like to upgrade.

Autoflower light cycles - adjusting mid grow Autoflowers can grow in pretty much any light cycle. What are your experiences with changing light cycles mid grow? I am currently around Day 24, running 20/4 but the humidity in my grow cabinet at lights off is very high. How would adjusting to 24/0 affect my plants now? Thanks!
