When to put the light on?
Panzora
started grow question 5y ago
Hey there, Do you need to put the light on the pots directly after you planted the seeds in the ground? Or do you need to wait untill they poke true the ground and then put the light on them?

Plant can't absorb light till leaves open. But I leave the lights on anyway because I don't mind paying my electricity bill.

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!

My grow kit will arrive this week. is there anything I need to watch out for considering the fact that they only have stood by the window (mostly cloudy weather) for most of their lives? I don't want them to get overloaded with the rays of my growlight 😇

How much light - PPFD - without CO2?
How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.

Add to lights, or get a different light?
Learning more about LED lights, I'm kinda stuck . I can either buy two more of the current light I use (bloomspect SL1000) OR does anyone recommend another light in the same price range? Or info on what to look for .. not limited on space just funds. Unless I found a used one

Which strategy with auxiliary grow Leds ? 3x20w Leds -Thanks !
Helps maturing but I wonder if buds are bigger. I used to put 3 extra lights 20 cm below canopy, leave many large leaves at the top and lollypop 30%. 30% is definitely not enough even with those 20w LEDS (50% is probably better). How do you use extra LEDS ? Where do you put them?

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.
