I have no idea what we were even talking about. That comment was from the beginning of the summer.
This was BK when he saw that you responded this morning:
Show us the facts then
Science is real indeed, not all of it sadly.

You show your 4x8, I’ll show mine. Pretty easy to compare imo?

Damn, I skipped from page 1 to 22 and this shit did a complete 180, what did I miss, maybe I need to go back a couple of pages..
As far as HPS vs LED, I am still too early to make my own assumptions, I know the data, it's obvious LED's do save on electric costs, but it's also hard to beat an hps light that you paid 200 buxs for over 17 years ago and it's still working strong "good ole betty".
In the end I still see how LED's are the way forward, even old stubborn heads like myself are starting to jump over on the wagon " you couldn't talk me into this a few years ago, but they are making amazing progress with these lights".

Back when I first starting growing "in the early 2000's" there was not talk about LED's nor PPFD or par meters, we had t5's, 8's and HID's..
I did not start learning about PPFD and proper amounts for each stage until this year, 17 years after doing this, so it will be interesting to see going forward how my grows change by using par meters and new lights..
I know by heart what the old style of growing produces, Im very excited to see what all these new develops do to my garden, I feel like Im back in my early 20's and learning everything all over again.

Ive used HID's for years, just this year I starting getting LED's, I think the HID will always have a special place for me, it's what I learned to grow on.

I have an LED in my veg tent.
High expectations lead to high disappointments.
My bet is that you will see lower quality results.
But if you wanna jump into the "high words no cigar" game, please do feel free.
Just check out some LED grows before.
Just have to respond to this,
Changing the area won't change the intensity the source makes.
"If you take the multiple sources further from each other you increase the area the light lands on, which decreases intensity" Thank you !
Finally you got it.
You cannot spread light, and still keep the same intensity. That's what me and Blue Brother was saying all along, you cannot add the intensity by dividing the source, only spread lower intensity to other places.
Just a reminder to those who are skipping the entire thread: YOU CANT ADD LUMENS (Source based measurement) you can add Ppfd.

Tec moves on but not all ways to the betterment of the industry involved. I dont care what light you use just dont be saying one is better than the rest for all uses. All of you would laff at what I use but no one ever laffs at the end result when flame hits it.

It's getting cold out here, so temps are starting to drop a bit in my grow tent. Rather that adding a bunch of extra wattage with a space heater, I'm gonna take down the bar LEDs and put up my CMH plus QB setup. It will be 20% more wattage, so a few more BTU's, but also more radiant heat hitting the leaves is an added bonus during winter. If it got real cold around here, I'd likely revert to straight HPS during winter. There really is no best lighting source, because it depends on several different variables.
