It's this right here, equal intensities of various lights. Granted they're selling their special "secret" type of LED grow lights but the study could still be valid. From https://thegreensunshineco.com/hps-vs-led-grow/
Shit storm I believe is the relevant phrase.......shall I join in or roll a spliff......hmmmm difficult one that.....notArguing on this thread seems like it will be a great use of time. In fact, this thread seems like it's going to be a real winner. (I can tell by the bars)
Have fun wasting your time.HPS has way too much green/yellow.
And those equal intensities were... what ?I will indeed. I should point out though that the study used equal intensities, not equal wattages, so that's a factor.
with cheap light meter you'll be able to go beyond terms like "looks dimmer","way too bright" - "looks about right"What I'm trying now is HPS with a green reducing filter gel. HPS has way too much green/yellow. I'm using this 1/2 minus green type, made a half circle shape around the bottom of the bulb several inches away, with space all around it for air to go through by hanging it from it's corners with clear tape. No sign of melting. It's just a 150w.
What you find is that it looks dimmer, because less green is reflected from the plants, but when you stick your hand in you can feel the light energy is intense. Kind of like purple grow lights look dim. I also have a few LED "lightbulbs" in there to fill in some extra wattage. The plants are looking like they prefer it so far, only a few days. The filter does cut the light by about 30% though. Mine was too bright before anyway. Seems about right now. These gels are made for going on hot spotlights so it's not a big safety hazard or anything, as long as there's a few inches space from the bulb and it's not on top of it where most of the heat goes. Under the bulb, no issues.
What is the ranking? 1%? Are these outlaw biker lights? I guess it means they must be pretty badass if they reach 1%.....not sure.
Yeah, toasting em up real nice. Who the hell smokes raw weed? Anyway I just wanted to bring that page to peoples' attention. Make of it what you will. I see it as bad news for LED supremacists. There's definitely something wrong with a light source if it always causes bleaching even at low intensity levels. I get noticeable bleaching with a 5 watter at about 8" distance.I appreciate your dedication to experimentation but it's hard to take anything you say serious after the curing thread and the BS toted there. Are you still toastIng your buds post harvest?
Yeah I know, but you can just ignore the results for their lights entirely. Then it's just a study. Could contact them for more details. Maybe they'll tell you if you buy a light. They do look enticing, though probably cheap Epistars as usual.It's a advertisement for someone selling lights.
Bleaching with a 5w LED from 8 inches?Yeah, toasting em up real nice. Who the hell smokes raw weed? Anyway I just wanted to bring that page to peoples' attention. Make of it what you will.

HPS still have a place in the grow light world, especially when you sacrifice 1/3 of the power by filtering out half the green. Why? Because green is the enemy of vigorous plant growth if it's more than 25% of the spectrum. It actually inhibits growth. I do still use LEDs but not exclusively.
