RH % required for certain LED lights?

Also, does the light spectrum look complete enough for both veg + flower? That is my intended use, since I won't have any other lights to supplement it with for some time

I've been growing with LEDs for 2+ years and never heard of that though there are recommended temps for LEDs to be running at or whether the light is waterproof. I really can't imagine what can happen if it ran at less than 45%. Maybe that's just the environment they tested it in. And do you know what's under that foil btw? About 10 million tiny little screws and if one of those diodes goes out it will knock out anywhere from 1/2 to 1/4 of the diodes on that light. What I'm trying to say it's a really poor design nowadays and you really should steer clear of that panel. Especially for 4 plants. You'll need 3 of those for 4 plants and probably 4 would be better. It's not a true 300 watt panel and if the diodes are running at 300ma it probably won't grow weed. Check out this thread and don't fall victim to the con artists.

Thanks, I will check that thread out

High levels of humidity can cause trouble for any electronics. Large indoor grows can struggle with high humidity especially in certain climates and during wet seasons. If the humidity is consistently over 70% Id be more worried about the buds than the LEDs though.

Nothing will happen if you run them at lower RH. However, high humidity should he avoided - and it should always be non-condensing.

The temperature is the range of which the manufacturer promises that the lamp will deliver what it says. Lower temperature is for the most okay, but don't go below 0ºC.
The higher the ambient temperature, the faster the LED degrade.

also remember the fact that we use em to grow plant`s and they also require a a specific RH to thrive

thanksfully our plants (unless as seedlings) do best at a relative RH (40-60%) I had smaller problems when I had under 30% in early Veg and I also saw Ppl with mold problems in flowering if there RH was much above 70%

same actually go for our Carbon Filter`s as they don't last long at a high RH as they clog up

so I guess a RH around 40-50% is to prefer

but now we do talk life length of LEDs, don't it also have something to do with how well they are cooled ? if the heat sink is big and have nice fan`s or not ? as well of the quality of the LEDs of course and at what watt they run at

no problem, if you experience problems in early Veg. with a RH under 30% you could look in to a cheap humidifier images.jpeg
at 35-40% you should be fine tho, and a bucket of hot water in the tent and some misting of the plants can often do the trick until your small seedlings have a root net big/strong enough to support your plant with enough water in a dry environment (I often only have them problems in the wither and early spring, rest of the season I got 40-60%)

and about the LED, don't go super cheap here, will only lead to headaches and wasted time, and I agree with Franjan, you need more to cover 4 plants, only real down side to LEDs beside there price is the space they cover, not like Big HID lights that spread the lights out

thats two big plants under two panels, 216x3W but a actual (output) watt on 472W
