Light to close or not spider farmer take a look ther autos Mephisto

They’re getting ready for bed. Or getting a little too much light.

So should I raise it during end of day when they droop like this ...the beginning of day they're perky last 2 hours before lights out the droop

It’s normal for them to droop a little before lights out. Maybe not 2 hours before so they may get light tired. Not every strain likes a ton of light.

If it was me, I would lower the light a little say 24” above the canopy and then use your dimmer and the Photone app - on the LED FULL SPEC PPFD reading- and set your PAR reading to about 600 PPFD. See what happens. You can turn up the light dimmer as they get bigger, etc.

Spider farmer 4000 450 watt using 30 inches above canopy 100% max output so the full 450 watt 20 hours a day look at the leaves I'm new to leds do they look like I should move them closer or further (the light)....lmk asap please and thank you

At 34 moles, your plants are getting a sufficient amount of light to produce a good yield. The manufacturer's recommendations for your light are here. The PPFD chart on their web site shows that the light is very bright in the middle and that level of illumination drops off quickly as you move away from center. If I were using this light, I would raise it to 24" to try to get more uniform light levels.

Plants respond to light in a variety of ways but the fact that they droop at times doesn't indicate that the light should be shut off. Leaves raising toward the light indicates that the growth hormone auxin is moving into the plant stems and is causing the leaves to more toward the light. That changes over the course of the day but it does not interfere with photosynthesis. They're different processes.

If you're not using a PAR meter, err on the side of caution. I would take my readings, use the highest reading, and drop 10% to establish a baseline. Leave your light at that level and then increase your DLI by a few moles. I've attached couple of graphics that illustrate what are generally recommended values.

The first one is from a company that apparently was a competitor to Photone. The second graphic is from the Photone web site. Check out where you are in the growth cycle and you'll get some idea of where your plants should be DLI-wise. And it will vary from strain to strain and plant to plant.

The Photone website has very good info about PPFD and DLI. Also, hit YouTube and check out the videos from Dr. Bruce Bugbee and "DeBacco University". The latter has shorter videos and is easier to digest.

my bad here's my right info I took new screenshots of app without my iPhone case on so it was affecting the app....

Damn I was using the app with an iPhone case I took case off and redid it with the diffuser white paper that it recommended ....here's the real info ....

If they are drooping 2 hours before lights out the easiest solution is to cut the day down by 2 hours?

 

[Owens33]

If you pay the $10 or whatever you can use the PPFD for LED grow light feature/reader and it makes the conversion easier. But 30K lux I think is around 700 PPFD? Which is not terrible, but a little high for veg. I usually like to stay around 500-600 PPFD in veg.

If your light has a dimmer, not sure about the different Mars lights tbh, you can raise and lower the light and adjust the dimmer to get the best light. Raise the light up for a higher spread of light = turn the dimmer higher till you find your reading. Lower the height = for a tighter space and you can dim it a little and save $$ on energy costs. Lots of ways to play with it.

Make sure you are using a diffuser though on iOS.

I am I was using with a case on iPhone took case off used the diffuser here's my readings I took screenshots for you

Still don't know how big area you are illuminating
