So you have them all in buckets of perlite?
That is perfect bro!
just drop the "pots" in the "tray"...
If I remember correctly from what Dewey said, perlite does not absorb too much... and you can do multiple floods a day... kinda like hydroton...
Every time you flood, you are bringing nutrient rich solution to the roots...
Every time you drain you are bringing fresh air into the root zone...
I have flooded as many as 12x a day... and it worked just fine... other than I had algae start on my tray... so I cut it back and solved that...
but it wasn't the plants that asked me to cut back..... it was my lazy ass that didn't want to deal with algae...
Ibelieve you will be pleased...
Just found this Auto Top Off Float Valve for RO systems... so that i can just keep the rez full w/o having to worry about it. The nice thing about this one, rather than just a float, is that you can put it on a timer so that it isn't always trying to fill the rez (like during ebb cycles).
I am glad you thought of that...
Here is a drawing by Al B. Fuct that may be of some use...
Also going to get one of those dual water meters pH/tds that just stays in the rez...
Nice move.. I use and love a hanna Grocheck like this...
Then i'll run a tube down there so that i can add nutrients as needed. (The rez will be under the house... so i don't want to have to actually go down there except to clean it out between crops.)
I suppose it would be nice to have some way to check the level...
A calibrated stick works well in underground fuel tanks... crude.. but it works...
Also looking at inline UV pumps... for keeping the water clean. My biggest concern right now is keeping bugs and mold and algae and crap out of the rez while its under the house.
Do you have the res yet?
I would most deff vote for one big one...
But you could use pumps to keep the solution circulating between tanks to have the same effect...
Bigger volumes of solution are more stable in pH, PPM, temperature...
I could easily get away with 30 gal for my 3x3 tray... but I do 70 gal...for that reason and the fact that I do not have to top off... the plants could dring 2x as fast and all I do is check ph and PPM...
I'm either going to throw a pond liner in a 300 gal. feed tank that i have... or daisy chain (3) 100 gal. smaller tanks together at their bases with compression fittings... either way, i need to find some way to cover the tanks.
.
I'd love to see pics of your options if you have them...
but as I said.. my vote goes for as big a res as possible without getting too costly on the nutes...
