Low Wattage Light Burn

Top o' the morning RIU!

I am getting ready to flip a plant to flower in my 27x27 tent. I have a 130w rspec qb for the tent which I was worried would not be enough. However,y plant seems to be super light sensitive. I habe the board ~ 28" above her and turned down to 98w. Anything more and she gets white tips


This is a lot less light than I had anticipated and Im worried it might affect yields.

Would it be effective to add another qb turned down low and hung up super high to help add additional light without burning? Or is that just going to exacerbate my issues?


Many thanks!

they will be able to take more when flipped to 12/12.
i veg with even less watts then you, yes they can be sensitive in that stage.
youre not even having a half sqaure meter there to light, the 130W will do fine likely in flower.
using 2 boards amd drive them low could be benefical, especially as your tent isnt that tall likely, while, see if you need it.

Awesome thanks for the info Cobshop! Its been a long while since Ive run photos and my autos seem to take all the the light they can get so I was worrying a little bit.

I am flipping next week and I will be curious to see how the plant's light needs change. I will try and get another board to stick in there and dim down too and see if that helps keep her stout.

Thanks again!

Well, until you force dial it in, most will blame you for Geowers error from what I've seen browsing here. It's not right to do that to people, especially because its light related. Yior spectrum is very bright to your eyes correct? Your plant finds that offensive. Easy as that bro. Diffuse & supplements the needed wavelengths in the right amounts. A Horticultural Lighting Group Is obviously struggling still.

It's obvious in the spectrums. Couple that with clustered diodes = lasers & a Hotspot plate. Diffusion would greatly improve plant health, increase yeilds up to 30% if you add far red.Screenshot_20220804-225508_Instagram.jpg

You obviously don’t know what you are talking about - HLG spectrums are fine depending on rig used - some run 3000k up to 5000k spec b .

“ Light Intensity “ is probably the issue as LED light is far intense , some strains have to acclimate . Dimmer control also helps. So how would you “ diffuse “ his light ?

Comparatively, these spectrums require unnecessary work. Enough to derail some Growers. I followed a thread by Hybridway & did the same. Pixelated drop ceiling vinyl/plastic and supplemented n dimmed to correct the spectrum.
Led light is to intense? Not following?

Absolutely ridiculous…. Ran HLG spectrums as is for 7 years plus perpetually and never had to tweak , modify anything .Both with far red and no red. Dimmer control and hang height is user correctable.

So according to your statement … a piece of diffused plastic will add “ missing “ spectrum ?

No, I did not say that. Cool, but what did you compare it too?? Being satisfied because you've never witnessed the potential is two totally different animals.
My statement reffered more to reducing existing overabundance in human spectrum by dimming & then targeting qhike filling.

OP …. Add pics . Let me help you.

Hang height 18“ from top of your canopy .
R spec QB 288 board is fine . I germinate with a similar board over either cuts or rooters.
Zero issue. I ran a simple 150w QB board tripod mounted as a propagation lamp instead of flouro.

So what does a plastic panel do for OP’S issue. ?

You mentioned Hybridway
This guy ? Ummm ok

Read about the huge bennifits of diffused light in horticulture. Haha! That's what I liked about the guy. He wasn't fake or phony, always kept it real. Notice no photochop? I got to see his long learning curve. He showed the good, bad & ugly in attempts to teach others from his mistakes . Now why don't you show some of his pics after dialed in???

Nice! But the op and hundreds of others post the same thing . Good for you, someone who's dialed in.

Haha! Desperate, that pic says it all. Those are hps sbs plants & the room is mid chop w/ trellis n plants falling. What, are you a Hybrid Hater too? If so why? I learned more from him then everywhere put together. Had to 86 the crap I learned to make room for proof & logic actually.
