Bio bucket venturi

[rule35sub1]

mine attaches right into the back of the pump, it is an aquarium water pump.
it is part of the design, I have not noticed any difference from using it, just figure it can't hurt using it.

rule, in the pic of the pump, i just wanted to point out and say, Nice high heel boots you have

 

[Dreamscape]

any updates on this gman ?? did you ever run that venturi with the Dart pump ??

Was thinking of purchasing the same pump.

Dreamscape: everything is finally getting together as we speak. the room is finally ready for the system to be built. Actually just finished putting the 2nd coat of paint on about 1 hr ago.

I had great obsticles to overcome before i could even think about putting anything in the room. removing oil tanks, cleaning, building concrete forms and laying 4000lbs of concrete, 6 mil sealing all arround the ceiling and elsewhere in a 20x4 room, adding doors, building hatches. Lotssss of work, lots of time, lots of money.

i have been taking pics as i go. i hope to start a thread soon. like 2 weeks. Run it 1 week and add the clones, wait another week, then start the thread.

So back to the venturi, it will be in the design of system. Also a flow back of the feed incase of to high of pressure in the system, also creating added waterfall circulation back to the rez.

i also decided to build troughs to house multiple net pots instead of using buckets. Im shooting for larger area to house the roots. basically almost 1 cubic foot per plant, a bucket is only.68 cubic feet. pluss it would have been $100 for buckets alone, im about $50 in for wood and 6mill lining so far.

After seeing some of the pics of the monster roots in the bio-buckets,I thought about all that space underneath the canopy that could be utilized, and came up with the trough idea, along with using a few ideas from over at gardenscure. (there are a few bio-bucketeers over there, u should check it out) troughs are also less plumbing = less chance of leaks & less money for connections & valves. gonna try for 20-24,space is the decider.

So we'll see if it works. Just rambling,

talk to you soon

I've tried one of those KeepAlive live well aerators, I believe it was the 600 gph model. Anyways, the thing is a piece of shit. For the same amount of money you can buy an air pump that would kick that things ass


I like the idea of the venturi, however, wouldn't sucking air into the pump reduce the amount of flow due to cavitation?? I'm guessing an adjustable flow valve would be mandatory.... Good luck with the project, keep us posted.


WB,

updates?

updates?

That's what I'm wondering. I have the exact same pump for the exact amount of buckets..24.. and just came across this venturi deal. Is this at all necessary or does the waterfall in fact supply enough and any more is just an overkill and extra step? I remember in BT's threads about the buckets that he actually ran tests w/a DO meter of his throughout various manners and set ups. I never saw a mention about a venturi there so I must ask... would they even make a difference? Is the plant going to perform better or not? Noone ever actually said yet and I'm curious...
Oh and those high heeled boots were sexy I had to go back and look to see what you were talking about

GOOD MAN!

I admire your work ethic and courage to try something NEW with the trough idea!

Best of luck to you amigo,
keep us updated if ya can

dreamscape: well i woundnt call the trough a new idea . i changed a few ideas arround and it ended up looking like DWC tray. Heres a quick pick, 4 trough/dwctrays. each trough is 3 ft long, 2 feet wide, 1 ft deep. actuall water depth is 9-10 in. deep, depending on water pressure.


about 32 gallons of water per trough, 5 plant site per through. 20 in totall. A 3600gph pump, 2 4in returns to rez. Each trough has 4 2in outflows, which flow to a 4 in pipe.

1 1/2in. water feed line, then to 5 3/4in. elbows inlets per trough. (been thinking to reduce 3/4 feeds to 1/2 in. to increase pressure, therefore moving more water in each trhough, still unsure as of now)





Pump can finally run without restriction with 2 4in returns to rez. i figuire with "head" and all piping on the pump feed, somewhere arround 3000 gph give or take 200gph. giving arround 20 cycles per hour.

160 gallons give or take in system



system has been running 4 days. waiting 7-10 before anything goes in, maybe may wait even longer then 10 days. i will hope to use my best judgment to when i may think the eco-system is ready. Im not so sure of myself in the biobucket type system yet, as this is my first attempt at hydro as well.

Ohh boy ive been busy. real busy. i got some serious effort invested in her. Hope she performs. Been playing with my DO meter as well, will report on that too..

thanks for the interest..... i know im excited!

Venturi update

Venturi update

Before i had spoke of placing the venturi before the water pump, this is a NO NO.

by adding air before the pump it SERIOUSLY DECREASES your pump output. the pump gets major air pockets, plus it cannot compress the air the same as liquid. Leading to poor output rates.

Just an update to some previous ideas.

FYI .......liquid can NOT be compressed...Air can however

 

[Cranberry]

FYI... you can get pond master {AKA. mag drive} with an air injector. Pretty trick a bit louder but I can see air in them buckets. "Plants like fizzy water"

 

[gmanwho]

cranberry: Yes, the fizzier the better, the more movement the better, Im sure there is a limit to how much blasting water you want hitting the roots, but thats something to learn in the field.

gmanwho: back when i was into areoponics them roots took some major blasting. would hurt hands when working with pumps on. I retooled one time with spinners, thinking softer would be better, well that was not the case. In biobucket threads i found many different flow rates. but the only limit seamed to be the ability to drain the water. I am at 18 change outs per hr. max was around 20-22 from other users of this system. Min was at 8.

peace

Thats something Ive been testing for some time now in one of my testrigs.
I run several biosystems to grow perpetual. And was looking to replace the airstones in every system with a cheap alternative.
I put the air intake at the hose barb elbow,..right above the water line when full.
The barb outlet is below the water line at all times and at the top of the elbow(that flat place that you usually see on poly hose barb elbows in the middle) i melted a standard air line barb into a hole i drilled in the barb. But the barb end that connects to the airline I heated with a lighter so that its barely open.I then connect a small 4 inch length of air hose to the melted air barb and place the other end through a small grommet in the bucket side right above the hose barb elbow, and I have a standard aquarium check valve on the end of the airline, so it only allows air in one direction.

Seems to work well only the check valves dont seem to last more than a month before they need replacing. DO meter says that DO levels are on par with the same sized system using 2-- 30-60 gallon airpumps and 5 inch stones. Im just not a fan of air into the buckets. Roots twisting all the time seems to slow growth somewhat, based on my testing. And a system that introduces DO into the water via the res. grows about a weeks worth faster using the same clones, type pump,everything.
Ill post back later with a sketch so you can get a better idea>its pretty simple though

Later GM

Getawaymonkey: I appreciate you input very much. As to is would like to minus out the overly loud air pumps, ( i have built an intake muffler & box housing covered in rubber sheeting to help reduce noise)

Now i actually am gonna look for your lava filter. i read somewhere about it and now i am intrigued. If i can find it, or if you have other info on it, that would be awesome.

thanks for the experiences
