I see. Excuse my imagination, it was fun to imagine how it might go off your pictures and description. I assume you aren't running all those bennies and the stuff that goes along with them (humics, sugar, etc.) correct? are you setup on a 4x8 table? How large is the rez? What is your target plant size with your system the way it is setup or the size with the most efficiency (I am thinking sog)? I am thinking the biggest limiting factor in your setup is the amount of space for the roots is this correct? Are you worried about anything building up in your PVC pipes over time? I remember I think it was ttystik did something with PVC pipes too but they ended up being a PITA to clean to he abandoned his project.
"this water is 24/7 running down one end of the pipe"
Are you referring to the 1 in. plastic inlets typically found on EF tables? Are the drains the same 1 in. drains typically found on EF tables (i.e. botanicare ) Are you running the water across the 4 ft. cross section of the 4x8 or across the 8 ft. section?
"so the water rises until it hits the second overflow. "
Is the second overflow stacked/mounted on top of the first overflow?
What is your plan on piping in fresh air? How will you keep the co2 from combining into your fresh air?
How many gallons of water do you have circulating during a run?
Seems like a cool all around system. How do you like it against your lava rocks compared at the same time period? Would you mind explaining how your lava rock setup was ran? Its always interesting to hear about new setups, helps stir the creative imagination.
Thanks for taking some time to read the questions and props to you for some great ingenuity and great effort.
I have used all kinds of shit in there. I have run many nute lines. I like the jacks the best because it leaves everything clean, and my plants have more density, and a better smell and flavor.
The roots have plenty of space. I have grown plants that yielded 6oz in a 4" tube about 14" long. When the roots hit the "T" then they have more space to spread out along the bottom and fill the pipe.
Target size is strain dependent. The purple kush I put in at about 14".
I use a bulkhead fitting for the overflow, and ebb/flow fittings for the feed.
Res is 110 gallon.
I am currently running tea and jacks together in the system with no problems at all. My roots have never been whiter and happier.
This is not on a 4 x 8 table. I use saw horses, and a custom "trough" to hold the pipes and keep them sturdy.
Cleaning between runs takes me 4 hours at the most. I fill it with bleach water and run a sponge around in there. change the tubing... thats it.
