answered grow question 5y ago
At this stage, I would go with 24 to 30 inches, as they grow you'll be able to bring the light down to 18 inches.

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. ✨🥦

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.

3000 watt power use
This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.

LED Kelvin Temp 3000k-6500k
Is there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

Hps mixed with mars hydro 600 yield?
Hey all! So i been thinking about ways to cut heat of course lol. So I’m thinking about getting a mars hydro 600 and running it with my 400w hps at 250w on the dimmer. Do you guys think I will yield about the same as if I was just running the hps on super lumens?

Hey I was thinking to make a quantum board from scratch but there are not much type of smd led's I could find online. So wanted to ask you guys if that would be a good idea or I should not even think about it? I can have enough of smd 3020 to do this but the last word is yours..
