Thanks prof for reiterating all that, nice even for someone who is following you w/o trouble to have a rehashing. Since it wasn't re-addressed in the prof's last post but it was asked, you cannot simply compare the two light company's graphs, there are too many ways of adulterating the data and...

I, respectfully, fail to see how this proves that "lumens are more than what just humans see" the internationally recognized (derived) SI term, Lumens, is EXACTLY limited to what humans see. Maybe I'm misunderstanding, and if so I really want to fix it, can you explain? Thanks

so what you want is a PAR meter, (see my earlier post for a pdf on PAR meter comparisons---pitfalls ahead sorry to say) and honestly, I think the cheapest "PAR" meters at our disposal are (our) plants. I've got some spinach tests going cuz they are fast and I plan on eating em alive anyways :)...

lumens measures what humans see, not actual light emission photons (which can be different wavelengths = different colors) p.s. more relevant is this info from wiki (trying to be helpful): The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total "amount" of...

I did suffer myself to read your comment and I believe it goes against the basic principles of this WHOLE forum, consider yourself warned. You are making this personal

Nice, another for the ignore list. Get phosphor blend listings and you can make claims like that, start in on me about me health and you've already penned "THE END" to your story bro. obviously superPAR is okthanks2 or a little buddy (join date Jan 2012, coming to okthanks2's rescue...number of...

speaking of not having a clue, finally down to ignore your annoying @$$ too. Never seen someone project so much on a forum. Seriously impressive bro, now find a mirror

bout to burn out but just wanted to offer you this undercover: you want green and yellow, no matter the genetics, its minimums that you need to meet (full spec should cover this) and ratios that you wanna tweak (blue and red bulb changes you guys are doing) but don't fear the light that is the...

Little tip, if you are using party cups, take a razor/sharp edge to the sides (think perforation) to the bottom 1/2 to 1/3rd of the cup and it should increase the impact of your positive offering to your leafy friend :) MPP edit: didnt realize you were going from seed, in addition to the...

You are seeing correctly, that graph does represent a not 'wavelength nm' true representation. But if you were ordering the wavelength spectrums by activity....type? or net END effect, they might be on to something. I know it sounds far fetched but beyond something of that nature, yea the graph...

Sure, 50% perlite might be a bit much (most mixes I see are 20-40%, but if you have an enclosed side container (opposite of an airpot) you kinda want a lot of aeration. Lack thereof + overwatering = willful denitrification via bacteria, assuming they are present. If they aren't you are kinda...

I was starting to get a negative feeling I was having trouble putting my finger on, I hope my excessive posting has alleviated some of the ego-biased posting ratio we all experienced. Peace and love

dude I saw that on their site.... (the ultras) have you emailed them yet? I had a couple beers and I don't think I should for a while at least. That graph is interesting ((((perhaps a rearrangment of light waves to show some kind of particular molecular effect? as the sun graph shows, there is...

Also, the reason why you won't find aquarium market bulbs with the far red phosphors, aside from the fact that they are expensive as all hell: (that sun graph prevails again) Why is the ocean water blue? what does that tell you about its properties of absorption? Damn corals never get the red...

yo dawg coral waves are legit for blue spec, same companies super blue is going into testing later. My thoughts on that graph: Perfect example of PAR. PAR is a scientific concept, not a strain/plant/species/genus/domain specific requirement set. Do what gardeners-philosophers have done for...

.. Yo bro, got nothin but love for ya but check this from the wiki on phycocyanin: "Phycocyanins are found in Cyanobacteria (previously called blue-green algae)." Doesn't mean you shouldn't target for those, just the graph that im pretty sure we both have seen gives a lot of significance to...

Sorry to run on with short posts all, but when you go switching light sources, remember that you are causing significant stress to your little leafy friends. Different nm's of EMrad have different energy levels associated with them and the best results have been seen with a more constant...

okthanks: Just because I felt a little personally indicated in your posts and exuding positivity is part and parcel to my being, pm me a very specific question and I will do my best to assist you. I can assure you that I have had no problem confirming the indications of the research reading I've...

Hey all, not always around but when I'm having a late night scouring academic databases I pop in to see your thoughts and respond with mine. If you are into Fact based, particularly PAR driven logical approaches to botanical improvement as well as general organic gardening info please hit me up...

ust because I can't remember where I picked up the theory, may not have been here, but is everyone of the understanding that mountain strains expect/benefit from a certain wavelength-heavy spectrum more than jungle dominants? Translate that as you like but it would seem to be a huge factor in...
