Leaves look pretty good. The plant has recovered from my earlier PH screw-up nicely for the most part. I have some slight drooping of the tips of some of them that showed up today. I suspect that is because I re-did a chlorine treatment late last night. Im going to hold off on any more chlorine for a while or maybe just go with a smaller dose - maybe 1PPM.
These are all lights ON pics, so the leaves are not really that pale.
Your Jacobs Ladder pic is actually kind of appropriate. I have been thinking seriously about ways to get a static charge into the root chamber - safely.
After watching those videos you posted in the non-linear PH thread, showing hi-voltage, and static effects on droplets and even streams of water, I cant help but think it might have some application in HPA - IF - there is a safe way to do it. Im talking safe for the plant mainly.
This one was most interesting to me. If a simple, low power static charge can effect a stream of water this dramatically, then moving some micron sized mist should be even easier.
I plan to try that trick, but using nute water. Im curious to see if water with ionizing salts dissolved in it behaves the same way. Im pretty sure it will. A static charge is different from the charge created in a solution by ionization of the dissolved minerals. That video looks to me like its the Lenard Effect creating static charges on the stream, which is in turn bent by the static charge on the balloon.
The problems Im anticipating are mainly in two areas.
-
What effect will a static charge have on the roots and the plant? I need to Google that to see if there is any data out there.
-
If that looks safe, the next problem is that nute water is pretty conductive. Every surface in the root chamber will have a fine layer of salty water on it. Im afraid that will just ground any static charge before it can build up.
There is also the potential issue of electrolysis. That should only effect the nozzles, but if the current is super low, it shouldnt be much of a worry - if at all.
There is also the potential of creating hydrogen and oxygen gas in the chamber. The risk is that any that is produced will be in the perfect explosive ratio. But, I dont think that will be a serious concern - if - the current levels are low enough.
This should be easy to test once I get a good, low power static source figured out. Not sure when I will get around to that though.
Assuming the droplets are negatively charged, the plan is to - somehow - charge the top of the root chamber positively and see what happens. I havent come up with a good way to do that though - yet.
