Thanks Jay, A very well done summary of the relationship of the variables that form a good recipe for a plants diet of light. This four part summary has linked missing pieces of understanding for me. May you be blessed for sharing your understanding. I tip my hat to ya as I am off to cook a cheap DIY meal for my plants. As I keep in mind what has been said; as well “The proof of the putting is in the tasting.” I hope my plants see an improvement in recipe. As I enjoyed every video of your that I have viewed, hope for more. MSC
thank you sir for so much knowledge..this is still bit confusing.can i show you my tank please.. have 5 ft tank (60 inch x 18 inch x 18 inch = 84 gallon) i have installed 8 led bulbs 2 x 20 watts 2400 lumen + 4 x 20 watts 2000 lumens + 2 x 9 watts 9lumenper watts and all are 6500k. is it way too bright?? cos i have lot of melting and silica at bottom. i run co2 too. please advice
I have a superfish 85cm led light that states it outputs 250 par at a distance of 20cm. (im presume this figure is not a submerged reading and the hotspot obviously) do you think this light could be capable of emmitting 30 - 60 par min front to back at the substrate on my 80 cm long x 30 cm wide x 40cm deep tank with 6 cm of substrate. Im asking because I'd like to try to grow some carpeting plants and if not sufficient was thinking of supplementing the light by adding a second identical fixture. You think that would be adequate lighting for carpeting or should I go in a different direction all together? And thanks for taking the time to read this whoever does. I should add im not currently running co2 was my next upgrade then was gonna add supplemental lighting
Bonjour super vidéo mais sais possible que vous mettez la traduction en français pour encore mieux comprendre car le par reste une chose que personne en parle. Merci d'avance
Wow that makes sense that water absorbs red light and not blue light lmao. So you’re saying when companies market their lights, they don’t account for this?
Does PAR change linearly with lux or lumens on a given LED light? That is, if an LED with max X lux and max Y PAR is dimmed to 1/2X lux, will the PAR also be 1/2?
Thanks Very clear explanations and a lot of knowledge! As in all your video's. They have been a great help! Also like your zero waterchange video's. Thanks and greetings from the Netherlands, Richard
could you make a video about making an LED light for our aquariums? anyway thank you, armed with yourr knowledge i now have a lot more confident in my project :)

I don't even have a tank but I like your videos for the science! Regards from Brazil
I guess the youtube algorithm somehow led you here lol

Can convert lumens to par?

My aquarium size 15/15/15 inc how much light my tank how much watt and kelvin light
so helpful thank you
nerdgasm all over the floor!

Thank You Jay, very well done! I subscribed and enjoy all of your videos. Looking forward to more.

yes.
Chihiros WRGB II 120 7500lm is it good enough for a good planted aquarium 300L / 80Galons ?
damn informative! thanks!

Already made one
Thanku for u r effort
Thank you for the free lecture professor!
