Beginner. Use LED. No exp with other light systems. Will only ever be a LED person. Work in electrical field, LEDs are so much more efficient and use a fraction of the power. I barely crack 2 Amps running 2 smaller LED Panels.

Started with a MEIZHI "300W" LED light. Real Wattage is 147. Very nice light, really like it, bought with about 30 reviews off amazon, has jumped to 80+ reviews with 4.5 stars.

Upgraded to 2 of the same lights. Real Wattage is 275 with both combined. "600W" Equiv....

Upgraded in the last couple weeks of one plant flowering, seemed to pop the buds out a bit, who knows though. Have 2 going currently, have had nothing but the 275W and they both look bushier than my single under the 147 ever did.

Seems to do best at 18" above plant.

Yes height with leds is all relative..all depends on power of led. And beam angel..most leds require different hight.. for instance Fluence lighting is kept at 6 inches above canopy..

Yeah, Brother Kraven has the schizzle on his lights! Lucky old man. heh

I feel humbled to say I have a Mars-Hydro 600W LED for Veg & Grow.

So far so good, though I may double up for my next grow.

How do you know?
I got caught with way more seeds sprouted than I planned and had to make room. I added an old 4' 2 tube unit with cool whites next to my super duper ebb and flow tray under 2 HO T5s
The boot tray under the CWs was top watered 2 - 3 times a day, 24hr light.
I shudda turned the lights off, hard to see.... CW and boot tray in foreground
they all look pretty close to me

I sorta think this is on topic but if it ain't, ignore me, I'll figure it out.
I only use LEDs in flower and they've been disappointing,,, 3 yrs old now tho

Hey Kraven!

Thanks, it's been an adventure. I'm starting to think the more plants the better, it's like these one child families, jeeeezus but
take a 6 or 8 kid family, much saner place, you can afford to lose one or two.

This article is under the section...how far do lights penetrate the canopy...
Straight from illumitex website.....
For the most part, we give LED lighting recommendations for overhead placement of fixtures. For growers interested in providing more light to the plant matter under the canopy in order to increase yield potential, we suggest utilizing additional fixtures to provide side lighting. Having some distance between the fixture and the sides of the plants will allow our optics to deliver an even spread of intensity (less likely to have “hot spots” of intensity along the sides of the plants). Just like overhead fixture placement, be cautious when mounting closer than 12” to the plants due to our LED array placement as well as our intense delivery power.....

I understand about the bleaching I get that with my I mite get a tad bleaching on a couple big colas but worth the extra umol..and I've never had bleaching so bad it was noticeable I'm talking maybe a couple grams out of over 1K grams ..I like the odds..but just my opinion..

All this prooves ABSOLUTELY NOTHING!
How do you you know whether your results were the light? or the nute regimen? or the strain? or the CO2 concentration in the air? or the time of year?

I've got my eight tube T5 HO fixture set with some new vivosun 6500k tubes, ready for my fall grow (old tubes were 3200k I think) veg segment. Staying with the my old setup (led) for bloom, as it worked pretty good. WH I'll be watching for your grow to see the progress with your lights.

Hey bro I use a combo of t5 and illumitex ns for veg..with leds the fan leaves are thicker and more sturdy my stalks are also thicker...led for veg is way to go but I haven't fully switched over ..
