Lighting schedule?
Many references state the when moving from vegetative to flowering stage the lighting schedule (indoors) needs to be reduced from 18-20 hours down to no more than 12. Why do many here stay at 18 or more the whole way through?

at the moment I'm using a 250W HPS and 2 40W CFL, this takes humidity down. When I will afford LEDs do you think that the humidity will stay as per night or drop down like maximum 10% or it will have same behavior as with hps/cfl combo? Thanks

Light schedule
I am doing an outdoor grow and also have a grow room set up for germination. Outside is only getting about 14 hours of light, is it beneficial to bring my girls in under my LED's for 4 hours to make sure they're getting a full 18 hours of light? then bring them back outside

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt f
I'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

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?

Too close to the “sun”(light).... any advice?
My plant grew close to 4x it’s original size during her stretch, 10-12” on day one of 12/12 to 46” tall. She’s on day 30 of flower and I set up a second ScrOG net. Other than blocking light to shorter plants, do you see any other potential problems this second net might cause?

Is this enough? 2 mars hydro 600 TS or 200 watts of led in a 24x24x36 tent,
Using a 24x24x36 tent, I have 1 mars 600 ts (100 watts) in there for one plant. I’m going to throw another mars 600 in there as well and grow amnesia haze with my northern lights. I have good ventilation, will this be enough wattage or should I get some CFLs for under canopylight
