Neither do I
but I have read stuff that a lot of smart people have figured out.

So did I.

I couldn't agree more.

I am using my biggest pump on the 4 inch system.
I use Low ppm to save money, and to make my plants healthier.

I use the chiller for disease control only.
It is the best insurance that your rez will stay disease free.

You will have to make sure
that your rez stays cool enough to prevent disease
by keeping the room cool and monitoring the rez temp.
It does not have a filter,
and requires that you purchase a pump
and the necessary plumbing.

Thanks for all the info Earl. I guess I will go back to 1000 since it seemed to be working fine. Have you ever heard this theory that if the ppm in your res stays stable that means that the plant is using nutes and water at the same rate?

Not all theories have proofs.

Just because the PPm changes
doesn't really tell you which minerals
the plant has used.

The tds should stay very close to the starting point.

indeed, so should I assume that in your opinion this theory is not proven.

yes that is logical, if the plant uses more of one mineral than another it could get a nutrient deficiency even with high ppm. This has more to due with nutrient balance than total concentrations. I guess the more accurately the nute soup is ballanced with what the plant actually uses the lower the total concentration.

What is weird is mine does at 1000 or 1400, it stays that way while my 40gal reservoir goes from 40galons to 10 over a 2 week period.

It seems the plant will use more or less nutes depending on how much they are given, I mean if you add extra N the plant will become more leafy. i have never been sure to what extent this is the total N or the mix of N to P & K.

So back to that system you built, are you going to construct a version 2?

What do you think of a similar system that would use a bunch of vertical tubes, with the plants growing out of end caps?

After building this system what do you see as the pro's and con's of building this tube style aero system vs some other aero setup?

This is version 2.0

I would love to see you do a tubular vert grow.

When you do, be sure an post a link here.

I am pretty happy with the design I have,
there are always couple of new ideas on the drawing board,
but you will have to wait and see if they work out.

Right now, all engineering projects are on hold,
due to my personal economic crisis.

All resources are slated to more lighting for the existing machines,
before I venture into any new projects.

I was jealous because DB had this on his thread.

sorry, I was not paying attention. Its not that I actually thought you needed another version. Its just that I figured with such a cool system you must be one of those dudes that is always engineering stuff. Its like if you met a guy that built the fastest car, you might start to wounder what the next even faster one that guy might build. Or maybe you are not that way.

I would like to see me do that too. For now I will just have to get by being jealous of your system.

If I do, I will. Truth is I can barely keep it together to get a good ebb-flow system running. So the closest to any cool areo system I will get is talking about one. Maybe in 16 years my kid will move out and I will retire and do nothing but.



sounds like good plan.

thats one kick ass water bong earl
