How many are there? And for now have lots of light. Looks like have 6-8 so your 600 will work best.

Are these stretching? What should I do for the 2x top that barely sprouted?
Viparspectra xs2000. Just moved it to a 25" distance and 50% light intensity hoping it'll help, but unsure if it'll burn them? What should I do? Top 2x seeds JUST sprouted and are just barely above the soil. How to accommodate all plants regarding light intensity and distance?

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 😉

Veg/Bloom switch
My plants are 5 weeks from germination, I have flowers and buds forming but I am starting to worry they aren't growing as they should (I want them bigger). I have had my light veg and bloom switches on throughout. Would you recommend I change over to just bloom switch now?

Height Difference when growing different strains in one tent
Im afraid my Gorilla will outgrow the Lemon Cherry significantly in height, will that be a big problem? or will the lemon cherry maybe catch up a bit in full flower so the difference in light intensity wont be that big? both same age. Spiderfarmer SF-1000 (2024 Version)

I don't really know when to switch the veg light to the bloom one... the manufacter manual says to turn on both lights in pre-flower stage. What do u guys think? I also lowered the light (200w output) from 67 cm to 60, is it ok? (LED Viparspectra V 450)

1 light or 2
I have recently purchased a Mars hydro SP 3000. Great light.. It replaces my Blurple Mars hydro exo 120. I wanted to ask what peoples opinions are about me using both lights for veging. My grow space is not that big. 1.8m x 0.8m and 2.35m high. Will it be too much light and heat?

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.

Light strength
2 of my autos have been harvested and now I just have 1 mature plant mid flower and I've started my 3 other seedlings. I've got a tsw 2000 w/310 wts. Should I keep my lights at 100% for maximum growth or should I back off a touch to say 75 or 80%?

UV LED slowing down growth? Sorry previous question without the question!
The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

From 24h to 18/6h during flowering ok (autoflower)?
Royal AK47 Autoflower: Changing from a 24h light cycle (since beginning) to 18/6h when already flowering - no problem or not recommended? The temp is a bit too high (~30*C) I think.
