Veg and bloom switch on 600w led
Kush_Monster
started grow question 5y ago
I have a 600w full spectrum LED grow light that has switches for both bloom and veg. Growing autoflowers, how do i know when to turn on the bloom switch? Also how far away should a 600w led be away from the pot at germination, veg, and flower?

Light doesnt cover every pot
So i've got 2 plants under one cfl lamp and i observed that that 1 girl is reclining to the right. As i see my Cfl this girl is standing right below the plastic part of the cfl and obviously gets less sun. How can i fix this? Changing place my pots every day will do the job?

Keep LED strip or remove?
So this is a space tub grow, other than the above head light it has a 3500k led strip running around the sides(around 4 meters) is it worth keeping this lighting? I'm only running a 150 watt growstar led ufo, which is fine for my canopy but my bottom isn't nearly as dense.

TRUE OR FALSE!?!?
True or false?!?! LED has a longer flowering time. LED needs less nutrient. LED has a more spread light output. After reading to much about it, I would like to know what GD community thinks. ๐๐๐๐๐

Led light for 60x60x140 not too pricey
I'm looking for a new light for 60x60x140 if anyone can recommend the wattage and a decent reliable brand. I got a cheap Chinese one that was fine but a lot of red lights on the bloom switch have gone out :( energy efficient led please

hlg550 distance from canopy veg
How far from canopy for HLG 550 during each stage? After starting with a cheap LED, without getting a par meter I think 18" @ 50% power, or 32" @ full power for veg? Start higher and increase power every few days?

LED light distance
Hey guys I'm kind of new to growing only been doing it for a little over a year. My girls grow really well they just don't get very tall I'm thinking it's because my lights are too close. Is this correct? Distance is 9 inches above canopy in week 6 growing critical 2.0 autos.

Light recommendation
what led light would you recommend for a Secret Jardin DS150W (77x150x200cm)? It need to have a remote driver and be full spectrum. It could also be 2 lights.

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?
