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.

Led on 18/6 grow/flower photoperiod
I have the idea to put a led in my second tent for pre growing photoperiod girls, I have some room left over for some autoflowers who also grow & flower on 18/6 light - leds can switch between grow/flower. If I switch the led to flower will that be OK for my photoperiod girls?

Hilfe zu warm im Zelt?.... keine Regulierung mehr möglich :-(
I have a question.... I only have a 1.6m tall tent and my big ladies are now almost 80cm tall. My problem is that the temperature at the leaf canopy is almost 30 degrees. I've already left the tent door and the apartment door open, but that doesn't help much; the thermometer is...

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.

Como racionar ciclos de luz diferentes em grows con crecimientos diferentes?
I have an indoor photoperiod strain in the beginning of flowering at 15 weeks and an auto at 3 weeks in the beginning of the vegetative stage. Both are under 18/6 light. They are in Scrog. How will I be able to switch the photoperiod to 12/12 since it's in the store in Scrog, and the 3-week auto can still stay on 18/6?

How to keep room dark during flower?
How important is it to keep the plants in COMPLETE darkness during lights off during flowering? Thinking of running some ducting with cut-to-size furnace filter out the vent hole on the side of the tent which supplies air right now. Will that be enough?

LED light distance
Hey guys I'm kind of new to growing only been doing it for a little over a year. My girls grow really well they just don't get very tall I'm thinking it's because my lights are too close. Is this correct? Distance is 9 inches above canopy in week 6 growing critical 2.0 autos.

Light stress during the night time
Question to outdoor growers. The auto flowering plant is growing in the garden, and sometimes there is light on during night time, can it cause light stress? It's usual light bulb, 40w, in some distance

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)
