Dimmable light height

[AMP]

I’m looking for info from the experts soo i came here… with 2 vivosun 1000 full spectrum with dimmable feature , should i leave it at the top of the tent 4x4x6 at all stages? I’m in flowering now and have it at the top at 100%. Any advice would be greatly appreciated. Thank you

I don't get the light dimming thing. It's in lots of tutorials and lots of folk do it, but I just don't get it.
If anything, go with the maximum distance the manufacturer recommends and let the light grow to the minimum or median.

Is the vs1000 only 100W? That would make sense. 200W in 4x4 sounds low.

I misread your first post I think. Thought it said 1000w. I'd download a decent ppfd meter or buy one of you can. Run the lights on full power and either lower or raise light to get the appropriate PPFD.

Hey guys thanks for your insight, i just bought a SE3000 to bring my 4x4 space up to 500 watts total .. can’t wait to see the results

Use the manufacturers recommendations for height from canopy. start there. Use a PAR meter to check light dispersion. Photone is free. Photobio Phantom is what I use. The dimmer is useful to keep from burning your buds. Sometimes one runs out of grow space. It's the light spectrum that's most important. And watch your plants. They'll tell you if they're getting too much light.

If your vivosun is a VS1000E it's a 100 watt board. You have 2 so your running 200 watts from the wall, maybe. 18-24 inches above canopy.

No E just VS 1000 , i Think the only difference between E and. No E is the dimmer. Ty for the advise

At 18 " on 100 percent it might burn the tops.

DabberDog hey dawg can’t remember if I’ve told you this before, I have a HLG 360 Elite. I bought the kit. It didn’t come
with a dimmer.
I don’t use it anymore. It grew good dope though.

I remember you (or someone) having one and perhaps turning me on to the one I have.
Getting nervous about how much longer it'll last. I got it with one of the Covid checks.
