Bare with me. I've been busy and I apologize. I am posting pictures of the 'first run' today.
I had some issues - improper drainage in the buckets, nute issues, minor mold, and PH issues which reduced my yield. In addition, it took way too long to set up. However - it's mostly done - I've got rocks in the buckets and proper PH meters with proper probes, so this run will be better. Pics "soon".
If you didn't see the original thread:
BANKSTER BUCKETS I'm using a modular top-fed bucket system fed by dual pressurized feedlines from remote reservoirs. The buckets are elevated and drain through corrugated tubing into ABS piping, which returns the water to the reservoirs. There are two pumps per reservoir. Each pump pressurizes one main feedline. There is one 1/4" minor feedline for each bucket from each main feedline. Each minor feedline feeds two sprayers. One system could run one bucket or 100 buckets (depending on pump/line size), and you can arrange them however you want. I am currently running a maximum of 30 buckets using two 2200gph submersible sump pumps (60x 0.06mm sprayers per pump).
I'll hopefully explain a bit more later, with pictures.

MOTIVATION:
Fractional Reserve Banking http://en.wikipedia.org/wiki/Fractional_reserve_banking ^^ Main factor in the cause of the current 'recession', inflated home prices, ludicrous bank profits, and inflation in general. The government no longer creates inflation by creating cash/money - the banks create it instead, through debt.
Example in a hypothetical micro economy: John deposits $100 in the Bank. The Bank keeps 5% on reserve, and loans $95 to Sally. (John now has $100, Sally has $95, and the economy has $195. Bank has $5 cash.)
As a result, the value of the currency has depreciated, inflation will result, and if John decides to withdraw more than $5 from his bank account, his bank will need a temporary "bailout" from the Taxpayers.
Fortunately for the economy, there's a $1 daily withdrawal limit at the bank - so John decides to write a check or use a card instead - prolonging the collapse another day.
The urgent problem? Our politicians dream our banks had a 5% reserve ratio. It's actually less than 1% (This theoretical scenario ignores debts unpaid and interest/bank profits on those debts, for simplicity of explaining the concept of Fractional Reserve Banking)
This is why we have the Boom and Bust cycle. This is far from the first time in history that this practice has decimated an empire. This MUST be dealt with, and in addition, the US Gov must stop borrowing from the Federal Reserve. There must not be interest paid to private entities for money that is printed by the Federal Government.
The Government, not the Banks, must be in control of inflation. The creation of 'money' must be the task of the Federal Government, not the Banksters.
This is still an in-progress system. I've just about got it tweaked. Drainage and nutes greatly improved this round.
I'm having severe issues with lumen shock causing bleaching and occasionally dried fan leaves.
What should I be feeding more (or less) of, in veg, to increase drought resistance?
I'm going to start using a combination of spectrums, rather than MH exclusively for veg and HPS for flower, but that won't help me with the current set that is suffering.
I still have to get my C02 going, which is supposed to help. It's 90% there, but I've got a lot of airflow going out of the room, so I'm not sure how much the C02 levels will be boosted.
---- Props to Obama for getting reelected ... and leaving Israel to defend itself. Good luck fighting in the House...
Everything is growing real nice... nutes are good, PH is good, CO2 is on.
There's a lot of airflow, so I'm not sure what the CO2 PPM is, but I've got a meter on the way. It's certainly under 1300ppm, because that's the cutoff, and it never cuts off.
I'm using a greenhouse relay from CO2meter.com, which runs a 24v solenoid valve, which controls the flow of cold water into a "tankless water heater". The tankless water heater removes the heat (to drain) and is ducted into the room. I've got it on a timer, so it runs for up to 30 mins and then shuts off for 15 mins.
The good news is that I'm finally able to turn my lights up to 1kw. The last run, they were on 600w because they kept bleaching (light burn) and burning the plants (nute deficiencies). I presume this was mostly due to the nutrient issues, but I think the CO2 certainly helps, as I live in an area with especially low CO2 levels, and the light burn was especially apparent this round, due to lack of reduced nute issues.
Question for the experienced... I had some lower leaves display nitrogen deficiency on certain plants. I corrected it, and left them on at the time, since nitrogen is mobile and I figured they may still draw from the leaves ... however, it has been some time and the leaves never regained their "green". Should they be removed or left as a "buffer"?
I'll take some more pictures soon... showing the progress, and letting everyone see how I've assembled things. I've been neglecting my log due to the pressures of setup, maintenance, and bureaucracy, but I hope to be more active online this winter and spring.
