Height Spider Farmer SE3000 week 5 flower
PAR increased to 600 PPFD, done by lowering the light to 35 cm above canopy. What do you think? is that too low? I'm using a Spider Farmer SE3000 (300 Watt). Anybody experience with this light? How high did you hang it from week 5 of flower to the end?

PAR/PPFD and light height
PAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)

Grow lights
Does this look ok? I have 2 plants not growing as fast as my macchiato plant. The other two are different strains, Runtz & Zittles. I don’t want to over do it but I know light is key so I thought I’d ask. Both 1000 watt uv & the other is led. I’m on veg week 5 of all 3.

Switching from veg lights to flower lights (blue to red) ?
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?

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.

Swapping day/night light cycle during flower
Day 22 of flower. Lights are on during the day, 8am-to-8pm but we need to switch to 8pm-to-8am to use the colder night air to cool our lights without using a/c. Would it negatively affect the plants at this point in flower to give them 24hrs dark & completely swap light cycle?

Would I benefit turning my lights on from veg to bloom at an early age with auto flowers? Or would it still be too much light for them?

Better temperature for early veg
In auto flower indoor, Early veg, is better have 18ºC/24ºC, or stai around 23°C during all the day. I have an Inkbird that I can set on 23, that is cool when is light off, it warm it up. But with light off it’s drop down temperature to 23.

Irregular light schedule.
I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her? My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.
