David Stone: What kind of material are the walls of the well made of?
justme228: Is there any way you can have a to little sump tank? Or dose it matter on
David Stone: Why do you use bulkhead fittings as opposed to hooking up plumbing to the
valve the ibc tote comes with?
Bright Agrotech: We would love to incorporate more off-grid/alternative tech energy to our
greenhouse. We just don't have the capital at the moment. Someday, maybe!
We're happy to help out and passionate about giving value to the AP
community. So glad you've found these videos helpful and please feel free
to suggest future videos!
Bright Agrotech: Yep, it all gravity feeds. There's enough volume and incline to get it
GlobalTubeTruth: Remember, most states offer a nice tax break for alternative energy. With
some effort, and not so much capital, your entire system could be running
off energy produced by sunlight, wind, & water. Three things you have
plenty of, and don't have to pay any extra costs to obtain. That's a series
of videos I'd love to see you guys produce. That in itself is a great
marketing advantage. Not only to attract curious, and respectful customers,
to buy what you grow, but also to buy solar/wind products
RK Castillo: So do you pump from your sump tank to your fish tank and your towers?
Daniel Rocha: I love your knowledge and information... however I do not like any of your
video editing because I have yet to see one of your videos that shows what
you're talking about. Might help to pick up the camera and show us :)
The KlezmerTube: Why are you mixing the returns of the fish with the filtered water from the
Bright Agrotech: The point of placing the pump below our towers is for ease of access with
having our towers at ground level. We have a depth gauge to let us know
about potential leaks or other errors.
Raven Leader: How do you prevent ground water from seeping into your sump hole?
Ronald Warner: I really enjoy your videos. You are very informative and a natural teacher.
Keep up the good work.
Bright Agrotech: Within the next few weeks we'll be starting to sell some bulkheads and
other fittings on our store. Keep an eye out!
RK Castillo: So Constant Height In Fish Tank...so it gravity feeds to the sump? It seems
like that water is moving pretty fast into the sump. Is it pretty steep
Bright Agrotech: Hi Sonny, Swirl filters are great, but we don't use them because our towers
do all of our filtration for us.
STEADFASTuntoDeath: Okay, quick question: Can I grow Sweet Corn this way?
Vishal Patel: My guess is that this allows them to maintain water levels in the
fish-tank, as well as make sure that all lines from the growbeds flow into
a single sump... but I'd like their answer to this as well!
gregg stephens: i wish our HomeDepot and Lowes had bulkhead fittings! :)
Bright Agrotech: Vishal is correct. Instead of lining everything up and having each element
below the previous one, or using two pumps, we run a single pump system
which means that the water is split. This means that some dirty water is
returned to the fish, but the math works out. If we split our water 50-50
and cycle the entire volume once per hour and the end of 1 hour we're 50%
filtered at 2h 75%, at 3h 87.5%, etc. Not exact but close.
Bright Agrotech: That is correct - It's gravity fed from the tanks to the sump.
Bright Agrotech: We're fortunate enough to live in a dry climate where it's not a problem.
But, if you do live in an area where that's a problem, simply install a
sump pump with a float valve in the well. Keep your inline pump up off the
ground too. If it's a serious concern, you can waterproof the well (EDPM
liner can be used to seal off the pump/tank pretty easily).
jack black: I idk if am just oblivious to the answer but am interested in starting an
NFT aquaponics system i understand the importance of a sump tank but were
would it go because the filtration will be done before it gets to the plant
roots an i see in many systems it goes after the plant tubes...should it be
just after the fish tank then go into the filters,then to the plants?
Sonny Smith: Thank you for all of your videos I find them very informitive and I
thankful you have taken the time to make them.do you see a need for or do
you use a swirl filter?and if not why?
sregev74: why put the pump so low? if you will have a leak the hole thing will be
Bright Agrotech: Thanks, Ronald! Thanks for the kind words.
Bright Agrotech: Cool, if we can afford to we'll probably implement some of these things
down the road.
GlobalTubeTruth: Thanks for answering my question. I think if you took advantage of the wind
in your area, and used vertical axis wind turbines, and some inexpensive
solar panels, coupled with a grid tie inverter, you could run your entire
system with alternative energy. The system would pay for itself, and B.A.T.
would be an ever bigger inspiration on a completely different level. Using
the water in your AP system, you could even set up a water wheel, and
incorporate hydro as well. Just a thought. Thanks!!
Bright Agrotech: Wouldn't recommend it..
Happy Heart Farms: Very informative and well done.
GlobalTubeTruth: With an aquaponic system of the size you're running, would it be practical
to run the pumps, etc on solar, and, or wind, as an alternative energy
source?? Have you ever considered doing that?? If so, why did you chose to
run off the grid instead?? Just curious. Thank you for all the very
informative, and educational videos. I appreciate you taking the time to
shoot them, and explain your methods. It's an inspiration to many, and a
service to all who have interest in this type of science.
Bright Agrotech: Correct - Everything goes into the sump before going to the towers (half of
the sump water comes from the fish tanks and half comes from the returning
tower water). It allows us to create a low point and have everything at
ground level to make maintenance and harvest a snap!
