light

Hello everyone so I got a grow going I’m on my 3rd go so I’m no pro. Using 2 Phlizon 1200w, I’m wondering about light height I know it says 24inches for veg and 18” for flower now my crops have been relatively short I’m wondering how I can make them reach and grow a bit taller. Like how often...

Could someone give some insight on IR light emitting from wireless cameras in grow rooms? Since i put it in 2 harvests ago i have been F***** with seeds....worst i've ever seen. When the camera goes to night vision mode you can see the 4 LED's light up and i suspect that's my problem. The...

Hey guys, so my best plant got fucked up and it missed a dark period. The way I have it set up is it’s in a tent with a light I have four plants growing. 2 flowering 2 not. They all go dark at a certain time but I put the flowering ones in a closet for more dark time. I missed putting them in a...

Young plant seems all over the place, preventing canopy penetration. Should I trim any leaves to open it up? Under 400w HPS w/ supplemental lights.

After doing research on ideal LED light color spectrum, it seems like cannabis plants need mostly red and blue lights, but also benefit from other colors as well. I want to do a plant racking system with a 2 week veg time straight from clone (sea of green), then 8 weeks of flowering. It seems...

Looking for thoughts on upgrading my current light configuration. I have a basic understanding of what's at play, but by no means comprehensive: I'm pretty overwhelmed when I look at options for LEDs (I understand concepts like PAR and actual draw, and spectrum) and I haven't exhaustively...

Hello anyone have any idea what my problem with my leafs are im thinking maybe potassium def my tap water is 7.2ph very high in calcium maybe think might be my problem? humidity is very low 30% but was fine all last grow im useing dolomite lime to keep my ph stable as ive had a few ph pens not...

Im looking into upgrading my LED grow light from a 600w vivosun to a TS1000 from mars hydro. It only pulls 150 watts from the wall (about half of what the vivosun pulls) and is running a quantum board. It gets waaaay better coverage and would be almost half the cost in electricity and better...

I'm in 7th week of flower and my light some how went off for 6 hrs but I have another light about 4ft from it so it wasn't in complete darkness. Will it be harmful to my plants? Will it herm? Please help with your thoughts!

Hey friends. First timer here, so first of all thanks for taking the time to read! I am doing my first ever grow in DWC. Things have been going less than smoothly so far, and I have had a couple run ins with smelly res water. I just wanted to get some first hand advice if I may, and...

Hi was just wondering what some people think the best led light would be for a cupboard set up around 1.5ft x 4ft wanting to get 2 plants in it, I’m using the same space just now for one plant using a 600w light but doesn’t seem bright enough and wanting a better recommendation for next time...

I am a half day into flower and I sort of had an epiphany on whether i shouldve cut these two lower branches off during my last defoliation/prune. It seems to be prospering but I fear not enough light (if any at all) is going to make it on these lower branches enough to give me sufficient buds...

Has anyone ever used and have a review of this light?

I have always been critical of any @MarsHydrofactory and their “blurple” lights, as well as any company really selling these lights and labeling them full spectrum, so when I seen they had new lights made from epistar’s SMD diodes, I just had to try it myself and see If this light compares at...

Has anyone ordered lights from the WISH app? If so how are they working out? I need a nice light but I’m in a budget. If I had a bigger light she might look better!

Greetings riu! I'm adding a 5' x 5' tent to my area, looking for advice on how best to light it up. I need relatively low heat of LED, but also want to take advantage of the UV and other benefits of ceramic metal halide. Buildasoil has a combo deal with a 315w CMH + (4) x 100w COB fixtures...

I’m building a HPA(high pressure aeroponics) grow system for 2 tents. Veg tent is 4x4 and flower is 4x4. For the 4x4 veg tent: I want to light an 18-gallon rubbermaid container, which will be my cloner (10-16 small clones). Also, I will have another 18-gallon Rubbermaid container for vegging...

Sorry guys, I hate to do this. I posted this in the led forums as well. I just really need an answer quick but I’m trying not to spam.. VERY NEW to LED. I’ve used LEDs on my past grow (I killed it) and so far on the one I’m doing now, but I don’t understand electrics or basically how they work...

hey guys!! New to growing, VERY NEW to LED. I’ve used LEDs on my past grow (I killed it) and so far on the one I’m doing now, but I don’t understand electrics or basically how they work. My buddy is an electrician so I’ll have him explain the science stuff but what I need from y’all is some...

Hey guys! So I have a 2’x2’x4’ wood box interior painted white that I’m growing in. Still trying to figure out ventilation but waiting until after I get lights figured out, I have some ideas already. I currently have one 32w Feit electric 3spectrum grow light I got from Home Depot for like 70...
