3200k my personal or 5000k a mixture of both would be Ideal I don't know why you would want to only chose one though. This is all LED based I assume are you counting MH bulbs they can be very good for vegative growth just expensive to run.

Lamp distance
Hello. I have a question about my lamp distance. I’ve changed the lamp to MARS HYDRO 2023 TS600 LED a week ago and a distance to the plant was 18 inches. During this week a plant grew and the distance became 12 inches. I lifted the lamp to 13 inches. What distance I have to keep?

Just ordered a 150W Quantum Board, can I swap my Blurple UFO mid grow to the new board? Is it possible to increase flower size this late into a grow?
My Blurple apparently uses 230W actual draw but is advertised as 600W. If that 230W value is correct, does that suggest my new, much more expensive QB is not as good? Will it make a difference to the plants health? What are the benefits from the QB? Thanks!

HPS 400w Vs MarsHydro TSW2000 cost
Alguém me sabe dizer o quanto menos uma luz LED gasta comparado a uma HPS ? Por exemplo, estou usando uma HPS 400w, e subiu 40€ na conta de eletricidade, se usar uma MarsHydro TSW2000, iria fazer grande diferença ? Obrigado

Better temperature for early veg
In auto flower indoor, Early veg, is better have 18ºC/24ºC, or stai around 23°C during all the day. I have an Inkbird that I can set on 23, that is cool when is light off, it warm it up. But with light off it’s drop down temperature to 23.

If I move 3wk old S.Diesel & Critical from 18hrs💡indoors to outdoors where they'll get +/-11hrs direct🌞. Is there still a risk of them going into flower even though they're still babies? I really don't want this to happen. They'll be in the woods so no chance to add extra light

Low budget light
I don't know if this is the right light. I'm gonna leave it for a week but if I don't see any kind of growth I'm gonna replace it with some good light. But since it's a wooden box I don't want to put a big light, maybe some stripe or bars, any low-budget suggestion is appreciated

Mars Hyrdo TS600 - 100w but mistook for 600w
I've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w. Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?

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?

will seedlings survive with just natural light?
At the moment I dont have a growing light and all the babies get is sunlight (about 15hours). Will this be enough? They are sitting at the window with a humidifier to keep them moistyyy.
