Lights for heat- 24/7 okay?
I really need the heat of the lights to keep the inside of my tent warm. To warm the air around the tent 24/7 would be expensive- much more expensive than using the lights all the time. But will this work with 24 hour lights? Will that stress the plants? Using auto flowers.

Hans panel 180 use veg mode or not
I've got a hans panel, it's got veg setting and flower. i had it all day on veg mode, seedling was stretching so i placed maybe 30cm from the lamp, but now leaves turned bit yellow. Would it be better to put it on flower mode and place the seedling further away?

Leafes curl up
Hey, these are my Autos at the beginning of day 6. The leaves are curling up a bit, is that normal/okay? Or is it light stress? The lamp is an AC Infinity Evo 4 300 watt, I had it running at 40% since day 1 and then reduced it to 30% after day 3. The distance is 45cm.

Black Light 30w
Hi everyone. What is your thoughts on introducing the Black Light (UV) during autoflower flowring stage? Any proof that it will increase THC and CBD ?

Mixing LED lights
Hi everyone! I am growing 4 autos in 3x3 tent under the p300 platinum led light. Is it ok to add an additional VS1000 as a supplement light? Or will the difference in spectrum cause trouble?

Light recommendation
what led light would you recommend for a Secret Jardin DS150W (77x150x200cm)? It need to have a remote driver and be full spectrum. It could also be 2 lights.

24 or 18 and 6
Been running my lights 24 hours a day on my seedlings. Since I am growing autos, should I be at 18 and 6 now? Or should I keep running them 24 for the first couple of weeks to help veg up little before giving rest? This is my 1st time growing autos and 1st indoor grow in 20 yrs

Longer Light Cycle - Mid Bloom
Is changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?

Heat, RH or overwatering? Or alltogether?
Hey my fellow growers! The grow reached 32Celsius the last 2 days in the last hour before going into night time. On that time RH goes down to 32% and this seems like it's stressing this lady a bit. Yesterday fed her nuts - maybe a bit too much? Thank you for stopping by!

Pasar de fase de crecimiento a pre-floración??
When do the plants transition from the growth phase to pre-flowering?? The fertilizer chart I have (grotek) shows these phases, but I don't know when the change happens, and is this phase when I increase the ballast power from 400 to 600??

qu'elle est le plus important à prendre en compte le nombre de lux ou le PPFD/DLI
lux, ppfd, and dli. While doing this, I realized that it’s hard to have a ppfd between 500 and 1000 for the seedling phase without exceeding the famous 7000 lux. We’re more like approaching 25000 lux if we want to reach the desired ppfd for this phase. How do you do it?
