sad. how people who aligned themselves with said company can still sleep in peace at night

are they still threatening my child on their posts over there? I cant see the forum unless I join and I will not do so

This is true.Sylvania, GE or Philips standard bulbs are very close to the Horti HPS(High Price Spread). And you might change more often for much less $.
*screams at his plants*people just need to shut up and grow and stop having bitch fest's on a forum.
sir they like mozart*screams at his plants*
YOU HEARD THE MAN! GROW FASTER DAMMIT!
Mine like the screams of infant koalas.sir they like mozart
Hi Sunni! How are you? Who's your Child?are they still threatening my child on their posts over there? I cant see the forum unless I join and I will not do so
no worries, there happened something end of last year and the happy family dissolved. no more hgl developement news and maybe 10 additional posts.are they still threatening my child on their posts over there? I cant see the forum unless I join and I will not do so
You would buy x4 single bars at 750 each. Why dont you just buy a cheep 660nm rig n toss x1 CFL in there. Not much difference in spectrum & you can see how wonky your plants grow before spending $3000+ on Alibaba that has a terrible record for screwing poeple over.I want to experiment with 4 of the GE Arize over a 4x8 tray ... see how it competes with 2 Gavita DE over 4x8...
Did someone post earlier a way to get the lights for $750 instead of $1000
It’s still useless.They are for outdoors supplimentation. Not an indoor light spectrum.
Do you mind providing some details on those supplement strips you have and how you are driving them?
Se, eye super hps, de no clue lol, bright.. I wanted the Philips master harvest or whatever they changed the name to... those are my picks. I use open wing and bend as needed. Those xxxl hoods would be my choice, I could fit 2 and run 2k in that 5.5 x 6...just picked up a 20lb co2 tank todayWith this being an LED/HPS thread, are there any HPS users out there who want to argue over which bulb is best? Or how my reflectors aren't correct size for my space. Or how I'm screwing my bulb in incorrectly?
Or are you all to busy "growing your weed" to come throw down?????
Kinda feeling left out of the conversation...![]()
Awesome, thank you. Been looking more into supplement options right now, but the single starboards from rapidled seem cool to try something like this out. Have a bit of time before I am going to get into supplementing what I've got, but trying to gather some info on the options in the spare time. Seems like some cool stuff is coming out soonish too.3 strips with 6 stars each so 18 stars driven by an APC or LPC 35-700 meanwell driverView attachment 4659847
good, but the 660nm can not fully substitute for an HPS, although it'll pump 3 times the amount of J/w into that region out.very interesting. it would be interesting to see how an MH/LED mix (3000k/660nm) would work in flowering
You always provide such good and detailed posts!
I did touch on solvent vs aqueous solution suspension for measuring absorbance in the THC Testing thread, so I know exactly what you are talking about, and even hypothesised a little on the subject: https://rollitup.org/t/more-thc-testing-uva-vs-uvb-vs-near-uv.1010801/page-8#post-15697300
I also found a more up-to-date study on the Emerson Effect, as it was bothering me that the original test was done with 700nm Far Red and I was wondering if there was any residual effect around that wavelength. What I found was that 720nm has the highest synergistic effect, followed by 710nm and then 730nm.
Here is the study: https://thescipub.com/pdf/10.3844/ajbbsp.2014.234.240.pdf
Here is a graph from the study

I guess I should have chosen my words more carefully, too. Quantum Yield graphs do show a small amount of photosynthetic efficiency beyond 700nm, so it stands to reason that Far Red on its own does drive photosynthesis. But not much, and then only in combination with light harvested from PSII pigments. I was really just thinking out aloud trying to figure out what was responsible for Emerson's "Red Drop" phenomena.
In any case, we do believe Far Red is an important spectrum. Just as we believe other spectra not normally found in typical white-phospohor LEDs, such as 405nm and 480nm, are important. We are hoping to show you guys just how important we think they are in the next few weeks.![]()
I'm reading photosynthsis done with FR not for the first time, in particular the figure "718nm". The linked .pdf study of the 2nd Emerson-Effect is very strong evidence, as it's done throroughly but still leaves much room for interpretation. So there is already multifold empirical proof available and theories emerging to explain said observations. There were, and currently still are, things not known at the time of writing or publishing of the various works, but with regards to the current accepted physical theories of the standard model, we can explain how electrons behave when moving through matter.Coffee this morning is pleasant. You never know what direction the conversation will go here on RIU.
Once a day in the morning I have a few ml of infused coconut oil and usually wait several hours before having a smoke.
I have been stubborn about learning the tech side of lighting. This conversation was one of the 1st times I opened up to learning more.
I'm looking to purchase LED for the flower room if I decide to grow next summer. I'm still favoring strips.
While I was following I went to the link from the illustrations Grow Lights Australia showed recently.
I thought you might enjoy the paper it came from. I found chapter 6 interesting.
