How to use a led lamp
How do you use a dimmerable full spectrum led lamp? When full power? When less? Distances? Mine is 1000w but this is what I find, maybe are specific for 600w one.

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. 😓

Light cycle messed up do I have leverage for one mistake?
Timer messed up the cycle and stayed on for an extra 12 hours.. So in total she was, for 24 hours in light... Soon as I noticed I manually turned off. Now the question is.. It's messed up and now off when supposed to be on vice versa, does the one mistake matter so much, seeding?

I Made a Big Mistake
I forgot the timer open and the plant has been lighting for 2 days now. Normally I have to turn the lights off at 6 pm. What should I do? Should I wait until 6pm? Or should I turn it off and switch to a new light schedule? Photoperiod - 5th Week of Flowering Phase

Ventilación y Luz en plantulas
I was inspired by McGyver and set up an improvised cabinet... How important is ventilation at this seedling stage?🌬️ (I left the door slightly open just in case)🤔 I also added another auxiliary light... will it make a difference in growth or is it a waste of light?🔌🔋

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?

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?
