16/8 is fine, but it seems most people like 18/6.

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.

IR cameras and ligth
Are IR cameras dangerous for the night cycle? I have my plants on streaming and I'm thinking of placing an infrared camera and IR LED I'm worried that the IR light can stress the plants and interrupt the night cycle. Wave you experience this with security cameras?

Light hanging distance
I’m not sure how high to hang my light. My plants seem to be all staying extremely squat and not stretching, though all seem healthy. I’ve been fiddling between 18-28 inches and 600-800 ppfd (ios meter app) and I can’t find a distance that seems to make them happier. D26 autos

Set Up Tent
How should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?

Best Light Schedule for Autoflowers?
I'm wondering what light schedules my fellow growers like to use with their Autoflowers? I'm debating weather the additional cost of a 20/4 is worth it in terms of growth and increased Bud Quality/Size over a 18/6 schedule. I would love to hear your experiences.

Discoloration and patches on the top sugar leaves
Leaves circled have gone lime green to yellow with the dark and light spots shown in the image. Is it light burn, wind burn or something more sinister?!

LEDs for 32x32 tent
New to indoor growing. Set up a 32x32 Vivosun tent. Currently have a giixer 1000w light, but wasn’t feeling the coverage was good enough for several plants. So I just ordered a second one. Do you think 2 giixer 1000w leds is ridiculous overkill? Any thoughts appreciated.

Anyone have any history with vibrating HPS lamps? Mine keeps making a buzzing/rattling noise. I’m thinking it’s the metal inside rattling on the glass so if I slightly rotate it it may stop? What do you think? Thanks!

Too much light or PH imbalance?
I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent? Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

Lightning question
Hey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?

How to reveg plants after preflowers by the end of april outdoors?
How big are the chances to bounce the plants back to veg after preflowers by the end of april and 14h of day length? Mostly cloudy weather, warm day temperatures (30c) and cooler nights (8c)in the old greenhouse simulated probably to much end of summer vibes.
