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?

Seedling growth rate Plants grow almost 1 cm per day (3rd week). Is it too little or correct? I have the impression that they still lack light (the rods are quite thin and long), maybe I should bring them closer to the LEDs?

Mars hydro 600 lights not going fully out Hi everyone I'm having issues with my LED mars hydro 600w when the timer is going to 'off' the lights are still very dim, with the plant being a photo period I'm worried the dimmed lights won't let the plant sleep and shock it or keep it in veg. Has anyone had this issue?

Lighting. Increase or stay the same?Hi, I'm thinking about increasing lighting to 100%... is it too soon? Currently at 60% 20 inches away (manufacturers recommendation.) I'm thinking 100% but staying at 20 inches away.. what's your thoughts? Too soon? (12" - 18" 100% for veg manufacturers guidelines)

Which of the two options do you choose and why: Option 1: 1440w over 40sqft giving 36w per sqft Option 2: 1440w over 48sqft giving 30w per sqft. The difference is an extra 2x4 of grow space. Do i go for more lumens or more plants? This is my first LED setup

Too much lighting?Too much/too many lights? Getting all popcorn buds/low yields. Getting a light meter this week. Going through by process of elimination on how I can get better grows. Read the manufactures instructions, but not good with technical electrical/lighting terms. Thank you.

Keep LED strip or remove?So this is a space tub grow, other than the above head light it has a 3500k led strip running around the sides(around 4 meters) is it worth keeping this lighting? I'm only running a 150 watt growstar led ufo, which is fine for my canopy but my bottom isn't nearly as dense.
