I’ll check what height / power gives me 400-800 when I get home. The lights I run are 2 240W in my veg tent 2’x4’ and 2 320w in my flower tent 2’x4’.

Oh my bad I misunderstood you. I thought you said you blasted your plants with the same lights at 11 inches.

All good I misread thirdstone’s reply with 400-425 ppfd as yours haha.

I’m also dabbing 
But yeah, looking back on this thread dude look at this the lights should’ve been on 25% and even further up… They were probably in 700 ppfd right there:
Cooked.

Did seeds arrive from @misterbee yet ?
Mine are on the way to you

20% at 13-14 inches should be fine in your case.
Edit: if you are running an 18/6 light schedule. Otherwise 15% 24/7.
Oh wait i’ll have to check my other tent since you’re running 600w panels
My other tent’s LED’s with warmer light has lower ppfd. 20% gives me about 550 at 11"

No I never heard back from him after he said they were shipping out 4 weeks ago 
Thank you man. I’m so excited to get that.
I’m running two 150 W panels. I’ve got them about 24 inches away at 50% right now they are hitting about 450 ppfd at canopy.
Once the plants get a little bit bigger, I’ll move them down, but they’re still just getting over recovering from too much light.
I’ve had a few users reach out about seeds now. The generosity here is crazy. I’m getting everything organized to store in the fridge long-term.
My plan is to grow one from each person who sent me seeds next run and then keep running them from here on out.
I already starting to plan out my second tent

Two 150W’s at 50% would bring you to 150W so i’ll measure there.
150W LM301H AT 24" gives me 263 ppfd.
Edit: 11" gives me about 540

Keep in mind I’ve got two side-by-side 150 W so even off to the side that second one is going to add some… skews it a little. Close enough, though I guess. I don’t know how accurate this Photone app is, but the plant seem to be much happier.
These ones also have lenses over them so I don’t know if that makes a difference

Is that a quantum board? Oh never mind those are the Samsung diodes…

The data should still be relevant my led’s take up the whole tent.
Edit: not sure how much the lenses do but i’d assume 5% difference either side of the range.

So you’re saying either my reading is off or my light is putting out more ppfd at that distance then.

Same thing happened to me when they offered to help me with some CBD seeds a few weeks ago. I hope they are just busy. But for the record, I don’t really need any seeds anymore if you’re watching @misterbee, so it’s all cool. Take care!

What are you using to measure? If it’s a phone app I can use mine to see if there’s a difference. Usually apogees are as accurate as it gets especially for led as I have E-PAR meters.

If you’re using two 150W QB boards next to each other that also makes a difference but I can measure that as well by turning one set of boards off.

The phone apps vary wildly in accuracy any given moment, must be calibrated, and require the use of a diffuser for more accurate readings. But it all depends on the phone’s photoreceptor and other factors.
+1 for the quantum sensor.

I don’t have any CBD seeds to share atm but if you want stardawg kush f2s I should have some left.

Make sure you are measuring with 4 walls (tent closed) and as few obstructions as possible. Most LED boards have their diodes arranged specifically to minimize central hot spots and diffuse light in a frustum shape, taking advantage of high reflectance for an even distribution.

Yeah, I mean I don’t know if you read the whole thread but for the first few weeks my plants are doing terrible due to VPD issues and light burn so I just downloaded that app to use for something…
If you think you can get a better idea on perfect distance for them than sure. Yes I have 150W lights. Vivarspectra xspro 1500:
I’d have them an equal distance but I’ve been moving the lights up and down so much. That’s just how they are right now - as you can see I’ve lowered the right one by about 2 inches since earlier today and it’s reading about 400 on the canopy maybe 425.
Leaves are finally starting to spread out on the plant that was super curled up
I was considering buying a lux meter and then just converting the result, but this Photone app was highly recommended for home use
