How much light does a seedling need?
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#

78,600 lumens at canopy, ok for pre-flower and flowering?
I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

Too early to turn up the dimmible LED light on my seedling?
Unsure if it's too early to turn my light up just yet or wait till more leaves are growing. Currently at 25% (10,000 lux aprox.) using the dimmer for a 120w LED at 20 inches from seedling. Thanks in advance.

Would I benefit turning my lights on from veg to bloom at an early age with auto flowers? Or would it still be too much light for them?

Should I keep my light hours or take it back down?
I had 20/4 lightcycle on my autos but because of humidity problems, I had to raise the hours with light on. First to 22/2 and now I had to put it to 23/1. Tomorrow I will get another LED lamp and soon a dehumidifier. Can I then turn it down to 20/4 again without too much stress?

I have a Viaspectra P2500 which is a bit big for my tent but I figured I could dim it and have when I upgrade my tent. I think I am burning my plants though so I am wondering what the maximum and optimal Lux/FC is for LEDs. I have the Light Meter LM-3200 app with diffuser. Ty

DO YOU USE LED DIMMER?
Você usa o dimmer de potência do led? Usa ele em 100% ou aumenta em cada fase (seed, veg, flo)? Tenho visto as duas formas e gostaria de ouvir de amigos mais experientes. Sempre buscando mais saúde para as meninas. ✨🥦

Light distance
Hi everyone, what distance from the light to the plant is recommended to start the vegetative period? I see many different measurements on the internet. In this case, it's for some automatic Red Poison plants, with a 360W LED light.
