I got it figured out... In a way. If a person made good soil, used probiotics (EM-1 on bottom and gokashi on top) and top-dressed at stages, it would be perfect, but... I don'tThat really is a great setup. I hope you get it figured out too, so I can copy it!
The engineer in me has latched on to this SIP thing. I'm thinking a pump and chiller would correct most of the root rot issues, and even provide a buffer for too small an air gap. And since a pump is needed for the chiller in the DWC as well, the SIP removes the need for the added (noisy) air pump. And it's shorter so might fit in my 62" high tent.
I'm going to have to make one for the next grow. Pity the poor plant I test it with...
My way, if you will...
I start by filling my planter with (insert your choice of brand) soil. Mine is an 18 qt planter. Fill your res up to the fill line which needs to be a minimum of 1" below the bottom of the planter. Mine is 1.5". The soil will soak that up pretty quick. Fill it again then plant your seed/rooted clone. Then cover the soil. I use a black garbage bag.
Keep the res full. This part is up to you as far as how full to keep it. I let mine get a gallon low, then refill.
This is the tricky part, but once you see the signs, it gets less tricky. For me, it's when the purpleish/dark color in the space between the leaf's veins and the wrinkle start. At the latest when the brown spots just beging to show. It seems to be at 3 weeks in my setup on average. That's when the water roots hit the res. I still haven't figured out why the deficiency starts there, but I'm not that smart
In top watering soil, it takes a minute to correct, but this (like hydro) gets corrected almost immediately since this is when I start using the nutrients. Like I said at the beginning, I've been using the Advanced Nutrients 3 part pH perfect line. I keep it at half strength (8ml/g). You feed every time you fill the res. Mine is two gallons, and this plant drinks 1 gallon every day. There is zero need for a chiller and zero need for an air stone and zero need to change the res or flush the soil.
That Green Crack grow went south because I had my fill line errantly marked at the bottom of the planter (doh). Since I have moved it to 1.5", my plants have been happy happy happy (1.5" because it leaves .5" of room for error)
Here she is yesterday. I can't get a good angle to show it, but this lil girl has filled the 32" x32" screen and then some. Biggest and healthiest plant I have grown in the 6 years I've been practicing
And this beast a$$ main mast
