Sometimes "wrong" is an environmental problem, maybe there's a reason one cannot vent heat to an external area so using HPS creates a thermal management problem that gas lights and LED may not have. I have experienced this myself, and I accept that I do (have done) many things wrong. However, all situations are not identical so sometimes it is easier, within a given use case, to get good results from T5 than from HPS.
HPS will not kick LEDs ass, per se, it depends on the LED. Sorry Doc, that's plain true at this point. HPS will usually kick ass on blurple low-wattage LEDs, but "kick ass" is up for interpretation. That said, there's a lot of fucking yahoos around. I'm not trying to pick a fight, just saying your assertions don't represent an absolute condition, but the more likely one.
NO insult or fighting words taken!
You are correct! I left out that home build COBB's have the clout to run with HID, and possibly pass it (something else to try when I'm able to "continue"!!)
That's what I was commenting on "Mars or Galaxy" = low output blurpple (kinda fun to put outside during a party with dose's) LED's!
You are also correct that at times, and for certain reason's, one cannot use some solutions to environmental problems!
Still, to ME...... I can not justify the use of those over the counter LED's.... Call me fussy (and I deserve it!) but, I just couldn't do it!
I would run multiple T5 banks and put a shit load of effort into cooling that.....
MAYBE someone with 4 or more LED's of the blurpple type would do us all a favor (Been thinking about this question for awhile) and run ALL of them at once on a run and see if that boost's the effectiveness in bloom for us? How about in a 4x4 area with 4 plants? My production set is 1K of HPS per 4x4, with 4 plants.....We would be mimicking the space and the plant #'s...kinda basic but, I would be interested to see just how that came out!
Anyone up to that?
Hps will kick any other light ass,but I can see things changing soon.what lights do you use ,what ya running dr who,it's the weeks from week 4 ,onwards that will tell me how good this light is,one thing is for sure ,the plant is in perfect condition to produce a decent yeild.Defo doing a express grow in my main flowering room though,first time I have grown it my self,smoked it before and loved it,but under hps,I know it will throw a nice amount,
The is no dowt that the early flowering and part vegging ,it worked very well so far,I did think they would have been far more stretching ,but it's not the nodes are nice and close,
If you can't tell - I don't like cheap overpriced LED's....I guess they do have a "place" but, should be taken with a grain of salt...see above...
LED's equal COBB's or nothing in my book. Go ahead, call me an "intolerant bastard" some folks around here (home) call me IB and we get along fine!
HID can be so much = DE, CDM, Dual Arc and good old MH and HPS.......Don't forget good old Mercury Vapor lamps! Run them WITH HPS during bloom and keep them a distance farther away (supplemental lighting for spectral influence) then the HPS.....I liked light movers for this.
See what happens then!
Nice posts guys!
