Which led? leds are not even close to the same. 200 watts can be dramatically different from one light to the next.

anywhere from 12" in flower (depending on your diodes) to 24" in flower... (depending on the diodes).. A safe veg height could be anywhere from 20"-36" .. Need to know the brand and model name of the led if you want advice about it.

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

what is correct light schedule for indoor germination and seedling, and then transplant outdoors?
I plan to grow a photoperiod plant outdoors from spring to fall, but the germination and seedling stages will be done indoors. For the indoor part, can I use a setup with 18 hour light schedule? Or should it be 12 hours? I don't want to trigger flowering when I put it outside.

HLG 550 V2 RSpec power/height in flower
I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.

With autoflower when do I switch from veg (5000k-6500k)blue light spectrum to flower lights(3000k-4000k) w/ red infrared ? Should I switch lights right when pistils start showing or wait until after the flower stretch when buds are forming?

Veg or Bloom mode for Autoflower?
Hiya Folks 😊 As I'm growing an autoflower should I be using the bloom setting on my LED light instead of veg setting? It's only a 200w system and I'm growing in a 3'x3'x6' tent. My plant has just done 28 days from seed!! Cheers 😉

Switching from led to hps for flower?
Howdy, does anyone switch from a blurple led board for veg, to a hps or similar style light for flower? Why, why not? Is it worth the little extra hassle to buy and install? I like my led just fine, but wondering if there’s more to be gained in flavor, quality & yield. Thanks!
