Oh no one is "limiting" LEDs... I am talking about the arrangement of specific diodes on a LED board. Which diodes are used, and in what quantity affects the spectrum. Not sure what you mean by "limiting". Every LED grow light has a different specific spectrum, even among the full spectrum ones. You can buy blank quantum LED boards, then buy whatever diodes you want, to arrange your ideal spectrum....then what's the point? You're reducing/limiting the LED when you alter the spectrum. There's a reason why we grow with full spectrum LEDs. That's not scientific at all.
HPS is cheaper up front cost and provides the benefit of radiant heat
LED wins in every other metric
my hps / led mix depends on the weather. Summer I run 100% led. Winter might be 50-50 or even 75% hps depending on temps. I think 600w hps + 250 led is too much for a 4 x 4. 2x 150w hps with the 250w led in the middle might work. That would be 550w totalIm thinking my tsl 250w and my 1000w HPS would work great together. I can even turn the hps down to 600w setting. Thing is, my biggest tent is a 4x4x6.5 and im sure 850w is to much. Like i know 1000w of hps in that tent is way to much. The 750w setting i am running now seems to be creating less issues. Wondering if I should turn it down to 600w and add the tsl? I guess you do about 50/50 led HPS so id be having more red than you at the 600w. .i dunno what to do lol
Are your winter buds the same quality and weight?

I just have a hard time seeing how HPS is cheaper up front, but to each his own.
I can do it even cheaper. 169$ and adjustable
I been reading this in a study some time ago where the scientists used "amber"-coloured monochromatic diodes that resembles very much the HPS SPD in the 600-750nm region, where HPS has its highest light output. The LED couldn't compete. To both ends, be it either blue or IR, the HPS still throws put photons and these will have effect.IMO if i were to do a scientific comparison, I would make a custom quantum LED board that matches the HPS spectrum as close as possible, it's zone coverage, PAR output, etc... and then a better comparison could be made.
Just watched a video about this. LED's sound like high octane stuff. Sounds like LED growers are on a whole 'nother level!LEDs can perform as well or better than HPS. But just about every large operation you see is going to have 1000 watt double ended HPS. Why? It is really two or three different things.
#1 the person running the grows (AKA) master grower is scared to death of LEDS, because of the additional nutrient requirements of LEDs. Remember if the plants look like shit the master grower looks like shit. So LEDS suck is going to be his comment
#2. If the boss forces the change to LEDS the master grower and his crew will be working their asses off defoliating the plants because you have to be more diligent with this under LEDS.
#3. The Master Grower is going to bitch like an old lady about the work until the boss fires him or goes back to HPS
#4. HPS penetrates further into the canopy and allows for less work by the grow team
#5. Let’s say the boss goes ahead and changes to LEDS, plants start getting sick. Master Grower blames it on a bad batch of nutrients. Nutrient sales rep gets called in. He would also pop pop LEDS.
Having ran both HPS and LEDS. LEDS are harder to manage. HPS you can just run basic nutrients and that is that.
It is not so much they are on another level. In my neck of the woods things are divided. The guy that got me into growing was HPS. We had a falling out and did not speak for a good couple years. He was moving and was asking me about my set up. I showed him and he literally called all his friends and said you have to change to LEDS. I need to be clear, all LEDS will grow plants. Some just out perform others. That is absolutely all I am saying about different lights.Just watched a video about this. LED's sound like high octane stuff.
