Here is an aero system I made using 4 inch PVC.

6 inch PVC is very expensive
and the 4 inch saves a lot of money.

I use a Danner 1250 gph mag drive pump for the spray jets,
and a Rio 600 gph pump for the chiller/waterfall.


Here are the pics.

I started with a 10 foot joint of 4 inch PVC
and a 18gl Sterlite tub




I used bulkhead fittings to mount the pumps outside of the rez.



With the 4 inch tube the 3.5 inch net pots won't work,
but the 2 inch with neoprene work great.



The float valve is connected to the blue tub RO rez.


and this RO rez has a small float valve
that connects it to the RO machine

I took some cuts from a Thai cross mother
and put them right into the neoprene
and started spraying them
with 200ppm AN sensiGrow @ 5.6 and 74ºf


In a few days we had lift-off.



Now I upped the nute load to 400ppm @5.6pH
and lowered the rez temp to 66º


At the next rez change I went to 600ppm
and kept it there for the rest of veg time.






Here is the waterfall
from the chiller pump.



The lights are two 400watt HPS.
Hoping to add more.
I flipped the lights to 12/12 last week.
More pics to follow.

very much so....i wanna try your space shuttle....which of the two do you like better even though they are similar do you like one more than the other???

also can you explain a little of how much RO helps and what it does....this is one thing i don't have for my dwc.....but thinkin of which one to get

If I would have figured out the 2 inch net pots,
the shuttle would be 4 inch PVC tubes,
with a little more spread between them,
(I could have put them closer to the edge of each tub)
and there would be a little more room for the plants to fill out.


If you build one
be sure and
post a link to your show
here in my thread.
Thanks.

and it does much better than dirt too! My unit looks pretty sparse cause I only had 6 plants sprout from the 10 beans and I yanked two of them cause they were boys AND I've cut clones from the bottom. I'm sold on PVC grows!

If you are using rain water
or you have a source of water that has not been underground,
then you will probly be OK.

If you live in the USA
and get your water from a municipal source,
more than likely
your water has come from a municipal well.

Almost all well water in the USA
is unsuitable for growing
due to the high Calcium content,
which has been dissolved into the H2o
for millions of years.

RO machine removes this suspended Calcium
through the use of a Membrane
that allows H2o2 to pass through it by Osmosis
thus leaving the Calcium behind.

Suspended Calcium will bond with other micro elements,
mostly Magnesium,
and this will be detrimental to your grow,
sometimes even fatal.

Purchasing an RO machine
is the cheapest solution
to getting around the Calcium problem
that you will always have with most USA tapwater.

Hauling bottle water is too expensive,
and too much labor.

Once you have added RO
your grow will greatly improve,
because you will have better control over the pH
and the micro nutrients won't be "locked out",
by bonding to the Calcium suspended in your tapwater.

If you have spent a $100 on good seeds,
it pays to have good water to grow them with.

RO is about 20¢/gl after you amortize the unit.
