I need an update on your bacteria problem, please. I just put pool shock (calcium hypochlorite) into my hydro system at the rate of 1...
BTW, this is not even necessary. There are titanium coil probe style coolers (not the cheapo 50W plastic one) that will cool large volumes of...
Well, I hope the original poster replies with how an 8 gph pump worked to keep things cool. My situation is a 1/2" feed using the ECO66 (@ 60...
Well WishBone, How did the chiller work with a low gph flow?
Well, how did it do?
Lumens don't grow plants. The proper spectrum does.
The spectrum graphs on these look good, especially the blue lamps. Here is the website version: Philips Colored T5HO Lamps Here is the pdf...
I would like more feedback from people who have actually used Orca Film. Thanks
I'm interested in more input from people using Orca film.

So no one else finds this stuff interesting? Hmm. I'm still looking for PAR/PUR values for various light sources. Travis
Yes, Swami is correct when stating that plants use the whole spectrum of light. They even use some spectrums not visible, like UVB, which I found...
For anyone interested, I found a calculator about PAR, PUR, Lumens, Lux, and Kelvin. I started a new thread that is more focused on that subject...
I was skimming an aquarium website (in German!) and found this very interesting, yet incomplete, list of bulb/lamp comparisons. I have...
I'd like some more info on this. Can you find a source for me to investigate further? Also, I don't know how PUR is measured or how it...
Well, 7.25 oz is a little more than half your normal haul, so all other things being equal, I assume that twice the LED wattage would have at...
I already have some T5 HO fixtures. I need some specialty lamps to put in them. The Nlites website has some interesting spectral graphs that are...
If I had special flashlights that were 100 times more efficient than any other light source, they still wouldn't grow plants unless I used ALOT of...
