If you have LED light, you definately should increase the light level to 400 ppfd! 150 is much to low.

150μmol/m².s is very low to me.
You can start increasing gradually to reach 400μmol/m².s

Looking at your pics I'd say the light height is decent where your at.

What are you checking with? How does the plant look? What's the light manufacturers recommendation?

Yellowing leaves & tips curling down on 14th day. Coco / Autopot / Hesi / Mars Hydro fc-1500Would gladly use some help with my first grow 🙏
2 main reasons come to mind after googling:
1. I overwatered thinking it's hard to do since I'm using the Air dome.
2. Too intense light. Was checking a lot of growers that actually grow 24/0 and went for it 75% 40cm.

regarding the light spectrum ratio. what is the ideal light spectrum for both the vegetative and flowering phases?
Do you use 3500K lights during the vegetative stage, or only use cold white lights at 6000K? do you then switch in flower to 3500K lights along with 370-780nm?

23 hours light per day?I’m running 4 autos in a 4x4 tent on 20 hours of light per day. I’m thinking about the possibility of changing the light hours to 23 hours a day and 1 dark hour. I’m currently on week 8/9, I’m expecting it to finish roughly 12/14 weeks from birth. Any thoughts on this growers?Setup. Lighting

Is it worth adding a LED 18w 2700k strip light for last few weeks of flower?Should I add this light for the last few weeks of flower? I have a Streetlight 18w LED strip see pics. I was thinking that if I added this strip designed for flower to my tent like a side light it may help my Viparspectra V300 in fattening those buds a little. Thoughts?

Danger of HumidifierGood morning everyone.
So I've recently set up my new TS1000 and I'm wondering is humidifier dangerous for LED lights? It's directly under the light 60cm. And how can I regulate the temp in the room without new equipment? It's too high at the moment.

Setting up air cooled refactor.I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.

Can I change my autoflowers light cycle withou reducing their yield significantly?I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity).
Even if I stress them, it would be better to not have mold than reducing the yield, right?Other. Mold

Do I need to lower my lights?Do I need to lower my lights? I'm using a Kingbrite 240W Samsung lm301h and I just went into flowering period. I think the light is a bit overpowered for the room, so I've left it at about 21 inches above the tops of the plant. At this distance, all areas are getting 27k lux.
