Separate names with a comma.
Another quick and easy solution for the "L" series scrubbers to answer the question in the OP, add an air pump and one of these air stones into...
It looks so simple to me, but I am looking at it from a different point of view than those on RC. Analog POTs are 1-10v dimmer knobs, VDM is...
No, second to that one. ;) I agree that one is just stupid hard.
Make no mistake, it is a PAIN in the butt to run, and you have to check it several times over a 30 minute period. Probably the second biggest pain...
Just took a few pictures of the light as it is today. I have to try and remember exactly how many of what I have in there but off the top of my...
The 'cool blue' (480nm) to cyan (505nm) is where the gap is with white LEDs and appears to be very important for overall health of plants, and...
From what I have noticed on this particular type of plant is it comes down to resin production/potency when you switch between Red/Blue to...
Sorry Scott, last 'thread jack' by me. Since we are on the topic of LEDs I just wanted to show the 'full box' I made, different sections for...
;) [media]
Well, in a pinch that is ok, especially if you need to do so because you are running LEDs in parallel, but just to clarify, I am only talking...
Little late, but just so you know, cool whites output nearly identical amounts of 455nm as a royal blue. It would actually be better to use CW...
All I see is more double talk from SM's latest response. Still not one link to any study to back up what he is saying. Also, WTF are the 'field...
So from Boomer's response, it seems organic phosphate levels are not a concern by themselves, but depending on other variables, they could be....
To me, the biggest 'mind blown' thing that has happened in the last few years is the fact that the Navy was able to get a patent on 'cold fusion'...
OMG, you need to stop, I want one of each of the things you have been posting today. LOL
We have somewhat, it just isn't very publicized because of 'big oil', but 50% of the fuel that the US military uses is made from algae and has...
Fricken AWESOME! So when can we start ordering custom sumps from you. ;)
That's exactly why I said I thought GFO was skewing the phosphate balance in the tank from 'natural' levels to very unnatural levels. I have been...
Haven't we been doing that for years now? [media]
Very old study, but it shows P levels for the ocean for organic and inorganic. Short answer, organic phosphates seem to be about 1/10th the levels...
