Is there any 1000w HPS that doesn’t emit orange light

No. It's the nature of HPS light. The color is the very reason why some people prefer it to other spectrums of light. It's the color it is because thats the color that sodium gas emits when it's electrically stimulated. It's now considered somewhat antiquated lighting option because the lighting technology has advanced quite a ways since the days when HPS was considered as "the best". But, there has a been a lot of great weed that has been grown under HPS light.

What you are looking for is called Metal Halide. It has a blue light.

The HPS is excellent for flowering. As is the MH. I use a combo of both.

Your results from HPS will surpass LED just fyi.

how will hps surpass led if hps emits around 120lumens per watt and some samsung led diodes emit 220lumens per watt? thats 100 lumens per watt more than hps?

The numbers don't mean anything to me. The final product is quite a bit better under HPS. Potency certainly.

I've used HID lighting for almost 30 years. I switched to LED and tried several lamps. I still use them for veg and making seeds. For flower I switched back to HPS. It just produces a better product and the plants seem happier. I haven't seen any Mag or other deficiencies, also not a whisper of PM since going back to HPS.

Your grow area is too cold for LEDs. I personally don't touch HPS grown weed unless it was supplemented with other lights.

I've tried all temps. The plants grew better with higher temps for sure but the higher the temps the worse the weed. As is the case with any lamp. Heat and humidity makes for hay.

me and my bro grew weed with hps for over 2 years we would rock 66wpsqf with air cooled reflectors and get okay yields but the weed was never the best quality when we started adding 10k solis tek metal halides end quality skyrocketed we also made the switch from soil to coco / rockwool.

You don't touch hps grown weed?? That's a new one. Guess you like weak weeds then. LEDs and bottlenecked genetics are the reason the dispos are filled with mids.

Kids these days lol

honestly im rocking a 2x2 grow tent with a led light and i can guarantee you that my buds will hit like a truck because im adding 5watts per square foot of UVB/UVA in my experience cannabis grown with supplemental UVB/UVA spectra hits harder and is more potent than hps grown weed. but everyone grows differently. not everyone wants their herb to get them blasted into outer space but i do :)

i just got a 150w hps from canadian tire to replace my kingbrite 4 bar 240w led and the hps is more yellow yes but it also is more sun like and warm than the led

with the led the plants crap out if the dimmer is over 40% and the humidity is too low (and winter is coming here so forget that mess) which is good for energy usage but i've never seen a plant do that before under any other type of light

my first grow in 94 in a townhouse basement was with a 1000w mh on the ceiling and pots on the concrete. the thai seeds we planted had dinner plate sized fan leaves before they grew a foot and everything was lush green. slow growing in the winter yes, no type of light will avoid that, but i don't believe an led can do that (without extreme environmental adjustments to raise humidity going on etc)

back in the day i would add a 10k solis tek metal halide(solis tek is out of business) rock it as a vertical bare bulb.

times have changed if i wanted to rock a vertical bare bulb these days i would buy a cmh ballast, a mogul socket lamp cord for vertical hanging, a adapter to convert the mogul socket into cmh socket and a 315watt 10k ceramic metal halide like this one 10k cmh(i havent tried this setup but this is how i would roll if i wanted a vertical bare bulb for UV these days) .

but i cannot rock a uv light of this wattage right now because i am growing in a 2x2 tent atm so right now im gonna add a migro 310 T5 h0 uvb light ima hang it 12 inches above my plants and give my 2x2 5watts per sq ft of uvb/uva i expect to get killer results :D <3 :3
