It is called a bulkhead fitting.
I use 3/4" and 1/2" inch bulkhead fittings.
They are pretty expensive.
The 1/2" are cheaper, but still...$$$
You can google bulkhead fittings
and find them online
cheaper than at the plumbing supply house.

Cool man, thanks for the info, I guess I will just grab some offline then.It is called a bulkhead fitting.

Hey Earl I just built a system similar to your space shuttle and was wondering, how long do you leave your water jets on for? I read somewhere that people go with about 1 min on 5min off. If you wouldn't mind clarifying this a lil for me. thanks

Beautiful aero set up. love the roots as well as your multiple colas. wish my set up was as space aged as yours. check it out

Right now I am running 30 minutes on, and 30 off.
I have tried all different timing
and I can't see that there is much difference.
I have left the spray off for three hours with no adverse affect,
but I wouldn't want to go much longer,
depending on the VPD

Hey Earl,
When you mix your nuts do you add it to just one side or what?
I am building one for a friend and he came up with this question last night.
The tank float that auto-fills your res is this one that works under pressure or just flow.
They have both and I'm not sure which to use. Figured I'd just ask.
Peace

LOL, man I'm still buying parts. After i saw your setup me and my friend said "That's it" this address all the issues we had. Water temp, flow, drainage. We where getting there but you put it all together. Any possible way you have a parts list for your design? Would help a lot.
Peace

Have you looked at this stuff, its called Radiant Barrier insulation. It basically reflects all heat energy instead of absorbing it like all other materials. It mitigates heat better than anything when compared to other insulation types, but if you used them in conjuction with each other it would be best.

Been a long time my friend hope you have been well?I have crossed a AK47 xBlueberry and its growing great but seems to be more of the AK dominent as it doesnt smell at all like the BB but the budsites seem to be more like the BB instead of the AK is this normal?As this is my first time too pollenate a plant.I was wanting the smell of the BB and not as strong as the ak its been flowering 20 days now,should it bye now be showing the final traits that it will have now?I only did 1 branch and tied it down away from the others and it was a very bottom branch and only got 15 seeds but all had not fully developed but i did get 3 to grow have 2 seedlings from it growing now plus the 20 day flower.Any help would be great.

I checked out your grow
and you don't need any help from me.
I hope you find a good strain from your cross.
Well its Friday again,
time to attend to the weekly flush and nute change.
Here are this weeks pics.
I lost the 600 watt digital,
it smoked the ballast.
I am running AN connoisseur @ 700ppm at 5.6
Sensizyme,F1, Barricade,Sweetberry(40ppm)
My RO is 40ppm
These rez shots are without using the flash.
The shoebox is getting overgrown,
even though it is just the one plant.
Some puberty porn.
And a parting shot of the back rez.

Earl i want to build a shuttle are something like it.I want to just grow a 2 are 3 big plants and stop during the summer cause down here way to hot and i own a A/C Company and am too busy.Is there any way you could help me out?Im gonna finish your hole shuttle grow and ask some ?? if you dont mind helping a old guy out id be greatful.SOMEBEECH

lol what size res and pump if i did the fence post for 8 plants? Woud a 40 gal, be good?

5 gls per plant is a good number for a rez volume.
Of course you'll need a 50 gl container to hold 40.
I use a Danner mag drive pump for or all my systems.
You can find then online for around $100
Look on ebay for used ones.
They are very simple
and the impellor can be replaced for $15
and it is the only moving part.
I like the 950 gph and the 1250 gph danners.
I got the 1250 danner on ebay for $50 delivered.
Along with "flow rate," a pump's "head pressure"
(or more accurately "pressure-head," "shut-off head," or "shut-off pressure")
is a term often used in pump literature to describe how powerful a pump is.
"Flow rate" is simply the volume of water a pump can move
during a given amount of time.
Pump flow rates are usually expressed in gallons per hour
or gallons per minute.
"Head pressure" on the other hand is more complicated.
"Head" may be simply defined as any resistance to the flow of a pump.
When pump manufacturers list the head pressure,
they are referring to the vertical discharge pressure head.
Described in very simple terms, a pump's vertical discharge "pressure-head"
is the vertical lift in height (usually measured in feet of water)
at which a pump can no longer exert enough pressure to move water.
At this point, the pump may be said to have reached its "shut-off" head pressure.
When you look at a flow curve chart for a pump,
the "shut-off head" is the point on the graph
where the curved line becomes horizontal
as the flow rate at that point is zero.
The higher a pump's head pressure,
the more powerful the pump.
To use flow rate and head pressure to help you select a water pump,
you need to know how much water you need to move through your system.
( the volume of your spray jets and filters combined)
And how much resistance (head) the pump will encounter
as it moves water from point A to point B.
For any pipe system,
in addition to the friction losses,
there are additional losses called minor losses.
(although in our case these losses may far exceed the friction loss).
These losses arise due to the pipe entrance and exit,
sudden expansion or contraction,
bends, elbows, and other fittings, filters, or valves, etc.
What this means is that the amount of friction created by the fittings
is the same as that of the specified length of straight pipe.
We can add this length of straight pipe to the total pipe length in the system
and compute the friction loss.
Here are links to the formulas
and ways to calculate the exact pump you will need.
Or you can just get a big pump and be sure.

Nice simple explanation Earl. Also pumps are commonly rated for rates relative to the head (height) pumped. The rate dimishes as the head (height) increases. As you have so eloquently explained, pressure head plays an important part in pump rates and the size of pump you need to adequately supply fluid to your system. One of the calculations which should be done is the maximum flow for the system to properly supply fluid with adequate pressure. Too much pressure and you create back pressure on the pump which will wear out the pump before its rated life time. Nice of you to supply us with the equations. Thx Earl as always
