Maximum / Optimal Lux or FC for LEDs and checking readings
I have a Viaspectra P2500 which is a bit big for my tent but I figured I could dim it and have when I upgrade my tent. I think I am burning my plants though so I am wondering what the maximum and optimal Lux/FC is for LEDs. I have the Light Meter LM-3200 app with diffuser. Ty

Boost buddy
Ahora con la subida de temperaturas estoy alcanzando los 31-34°C en el indoor. Uso Boost Buddy un generador de CO2 a través de la descomposición de bacterias. Solo con eso ya estaría bien o debería modificar de alguna manera el indoor para no llegar a esas temperaturas? Gracias

Grow Light Popped Its Clogs.
Hey Guys😬 So my grow light has popped its clogs, but I am currently unemployed and broke, and the flat that I live in does not have enough sun to move the plants to that source. Anybody got a really low-budget solution or idea? I can construct if need be. Wanting at least 200w

How to measure lumens of a full spectrum LED light.
Since a lux meter only measures certain spectrums of light, how do I use a lux meter to determine the right height of my full spectrum grow light? I have it at the recommended distance but I have signs of light stress. Bleaching of some upper leaves. I moved it up 4 more inches?

300w COB CREE Distance?
I've put my 6 seedlings under a 300W COB CREE UFO light, atm is a 30cm distance from them, I do hope is not too close. I've only a 140cm height and more would be problematic to manage in the long period.

Is this light enough to cover my tent?
Hi, I was wondering if my light is big enough to cover the whole tent. -I bought my light from a friend of mine, it says 600Watt but actual wattage is 134W. (Only thing I know) -The tent is 2x2x5 and I'm planning on growing 2 autoflowers in it

Light pointed at white wall for supplemental lighting?
Does it makes sense to have a small 300W COB LED pointed at the white flat painted wall for supplemental lighting? If I point the light directly at the plants I would surely burn them but have no space to move back.

Comparing My 2 LED lights
Light comparison. Ive got 4 plants in a 3x3 and am currently running the ViparSpectra V600 LED. I just got offered a MarsHydro TS1000 and Im not sure if it's an upgrade or downgrade. I've watched so many review videos and end up more confused. Should I run both?

Lighting. I have 3 SpiderFarmer SF 1000 lights with 4 T8 barina 2ft around the edge of the tent. Does anyone recommend a different Lighting set up? Does anyone know how long these spiderfarmer lights will last? I have a 48x48x80 tent with 4 plants at the moment.

How many watts do I need for my small tent?
I am using a full spectrum LED that draws only 30W from the wall but it might be too weak since my plant is getting lanky. I have moved it closer to the plant but now I am afraid of over-heating. How many watts LED would be sufficient for my 40cmX40cmx120cm tent?
Plant. Too tall
Plant. Stem - Weak

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?

Is that possible to do grow light with Samsung LED strips?
Going deeper into idea of doing the quantum board from scratch but instead SMD LED's there are lots of strip LED options. So I want to ask you guys if I have an aluminum plate with a heat sink and coolers, can I fix those stripts there? Or can I rip them off with a heat gun?

Learning more about LED lights, I'm kinda stuck . I can either buy two more of the current light I use (bloomspect SL1000) OR does anyone recommend another light in the same price range? Or info on what to look for .. not limited on space just funds. Unless I found a used one
