Led Grow lights
I have a viperspectra xs4000 light 480 watts I am running it at around 25% on the dimmer switch and my lights are about 24" from my canopy. I've noticed some of my pistols wilting and looking stressed. Should I try to move my lights higher or continue dimming them down more?

Light came on for about 30 seconds about 3 hours into the dark cycle
So Im 3 days into 12/12 and I bumped my timer last night and my light came on suddenly during the dark cycle. I immediately shut it right back off. Was I wrong in shutting it back off right away? Should I be worried about anything?

Lighting Change
Okay, I feel like I am asking a lot of questions so let me apologize for that. Lol. So my plants just seem to be behind most people's I see on here.Is it too late to change my lighting schedule? My theory was northern hemisphere gets many days 24hr lighting. Good or Bad?

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.

Lights too close?
While trying to figure out why my plant is so dwarf like I realized it might be the height of my lights. They’ve stayed that position ever since installed them. The problem is they’re basically at the ceiling of my box. Is my set up limiting its growth too?

Mars Hydro TS 1000 [3500K,100W, LED light] (Plants @ 3
Questions: See photos. 1. MARS Hydro TS 1000 will not support 4 cannabis plants, correct? Support = Obtaining full plant potential. 2. The Chinese 3000K lighting won’t “hurt” my plants in veg, right? It’s just simply isn’t the lighting that works for veg growth, yea?

Contemplating putting 2 plants outside. I have 8 in a 3x3 with Mars hydro tsw2000. It’s pretty tight in there. What do you guys think? Is 8 too many for the size and light? Or should I just leave them as is? I think the the pots are 3 possibly 5 gallon.

How to manage grow light height with plants of different sizes?
My grow light is suspended (offset from plants) about 10” from the canapy of my two LST’ed plants but only about 6” from my control plant (no LST). Everyone seems happy, and I am not noticing any burns or lack of growth (unless too close can stunt?). Should I rethink the setup?

Led Light distance and power question.
I have a Lumatek Attis 300w. For the beginning of vegetation stade, I place it at 60cm of the plants and configure power on 40%. I read that very young plants needs less light in the very beginning of their life but I can't find precisly what distance and power use.

Voost VST240
Looking for a good budget light for a 4x4 grow. The Voost VST240 looks like a fantastic spec but no real information out there that I can find. Any users? Also considering a Migrow Array when the bigger version hits the market.
