Hi there OG.
Im new with Leds and i spend some money on two Quantum Board one of 720w for veg and another one are a 1000wlm301h ir +uv.
Im scared with the potency of the LED.
I always used hps and hqi and i changing now to LED universe.
Anyone have any tip about potency of leds on veg to make my roots more strong possible? Without burn?
Im complet new on led world and i need a light.
Thank you og

hey @HollySun91 , I know you’ve already spend $$$ on your quantum boards but also look into Bar fixtures vs panels; better spread and make sure they are DIMMABLE.
Are your boards dimmable?
I have a mars hydro FC-6500 for my 4x4. It;s rated commercially for 4x4 and non-commercially for 5x5’s. I have mine hanging at the highest point of my tent and use the dimmer to adjust the PPFD values for all growth cycles.
I also run panel lights from Mars (TSL2000’s, TS1000) and Spiderfarmer (SF2000) an from comparison grows you can’t beat the spread of a good bar light.
Getting a small PPFD meter really helps dial in LEDs, or you can go with suggested hanging hights if you wanted to move the fixture.
Here’s a link for the cheapo PPFD meter that I use:
Another thing, as you enter into the world of LEDs you have no choice but to start supplementing weekly with cal-mag or just epsom salts. If you don’t you’re gonna think something is wrong but for whatever reason LED plants are cal-mag hungry!!!

hi @HollySun91
the photon app for andriod or iphone is also working like an charm. a cheap soulution to give you atl east
some numbers to work with. if you have an andriod device it is free to use on iphone they take a couple of bucks from you … the meter pigeonman suggested would of course be more accurate! i would also like to have one XD

Cool in know @m0sirys.
Thanks by the tip
amazing!
so yeah, set up your lights and then use a phone app meter or something similar to what I linked for you before and you can totally dial in your lights!
you want:
Seedlings: 100-150 PPFD
Veg: 200-300 PPFD
Flower: up to 1050 PPFD.

This is a good option! I used it before having some spair coin for my PPFD meter.
The think for me was not being able to close the tent to take the readings with my phone app. With the separate meter I can place the sensor where I need it, close the tent, and then take the reading with my phone via blutooth.
Addtiionally I since my dimmer/balast is mounted outside of the tent I can adjust my PPFD with everything fully closed to get absolute values.

@Pigeonman you ever get a chance to compare the phone app to your meter?

Yes. Which is why this cheapo spend the monies on the meter.
It’s also my OCD from film industry lighting when that was my steady gig… having a budget-but-effective stand alone light meter is way to me to not end up getting it.
It took a while though as most these meters are $300+ and that’s no 
but once one came up with positive feedback from actual use nearer to $100.00 I scratched that itch really fast…
…now if only I can find a lightly used 4-6 tonne dabpress for $200-300…

Another option… The UNI-T(bluethooth version) only $35. Shane from Migro worked with this company to get this very close to accurate with an apogee meter. I still use mine to this day. Works excellent and I have not had any problems. Pair it with your phone and use the app. You’ll be up and running in minutes.

There’s a cool trick (that usually works) for switching between Canadian and US Amazon listings. Call up a listing and then change the “com” to “ca” or vice versa in the URL.
