Aeroponic Space Shuttle

Nice job guru Earl. Always read yours [post. Respect bro

All of the 100 gallon per day units on eBay
will give you 110 gallons per day
if you have water at about 80 degrees and 100 PSI
most homes are about 60 PSI with 60 degree water,
so you can expect less performance.

You may need to put a pressure gauge
on your water line to see
what kind of water pressure you have.

I think you need 60psi min.

If you don't have 60 psi,
then you may need a booster pump.

Check out RV pumps,
as they are "on Demand" type pumps.

So anothier journal "ride on the shuttle" still talking about yur last monster' deff. Need more, so whats cooking in the bay doors.!!! Db.

oh my god that plant is a monster!!
is that one of earls plants? how tall is that beast?

RO only is good for starting seeds.

You do no need to test the pH of RO

Earl,
I saw the 950gph pump box, which one is that, the chiller pump or the sprayer pump, and what gph is the other one?

Thanks!!!

I have the 950 for the sprayer and the 650 for the chiller.

Shuttle upgrades.
I have a new pump 1250 gph.

New RO rez and fittings.

I moved the chiller to another system
and I am running the old space shuttle
without a chiller.

I have moved the pumps out of the rez
and I am hoping this will help keep the temps inline
without needing the chiller.

I have added a 3/4 inch filter cartridge 150 mesh,
under the christmas tree, and all that spaghetti



I have a fan mounted to blow cool air into the rez if necessary.
I should be able to keep the room temp in the low 60s.
I have re-inforced the stand base
and cured all of my small leaks with silicone and PVC epoxy.

Another day or so of running empty to insure all is well, and then launch #4

I read through the whole thread and there is some really great info in there.

Two questions though:

Could you possibly elaborate on your reservoir system and what you meant by a float valve to regulate the water levels?

What is "RO" water? (didn't find it in the newbie terminologies)

Thanks Earl.
I've copied your design for the most part.
Except I decided to have the pump out of the rez from the beginning, for the same reason, I'd rather it not heat up the water, and I wanted to try and run without a chiller.
I connected my pump a little different, but same concept.
I put in another bulkhead and ran piping out to the pump, and put the pump prefilter on the inside of the rez attached to the other side of the bulkhead.
I also did not have as much space as you unfortunately, so my 6" tubes had to go into the low side rez some, but that should be ok.

RO is reverse osmosis water, from a RO system. It takes tap water and filters out almost everything, so you get good pure clean neutral water.
The float valve is like a fill valve in a toilet rez. It has a "float" on a stick that closes the water inlet valve at a certain water height.
Its a "top-off" system like you might find in an aquarium.
He simply measured the water level that represented the desired 20 gallons and set the float to close the valve at that point, otherwise it lets water flow in. In his case, the water is flowing in from a remote rez full of RO water, that is gravity feeding the float valve on the pump side rez in his shuttle.
I picked up a nice side fill mini float valve from an online store, under 20$.

On a side note, I tried silicone instead of plumbers putty and it did not go over so well. Ripped the baskets out and cleaned it and re-did it with the putty. I did however use silicone to install the basket in my actual sink and it worked fine there haha.

So far everything is going well except a couple of my DIY bulkhead fittings are leaking. After spending entirely too much time trying to get them to work, I think I will just break down and buy some.

One of these days I will get it all finished.

I got this one earl.
RO water is Reverse Osmosis water. RO is a way of removing the solids in the water. If you have tap water with a high TDS (total disolved solids) then you will want to either get an RO filter or buy gallons of RO water, pending on how much u use.

This is a float valve.

You hook up the valve so it is inside of the resevoir. Water travels thru the valve and when the res fills the float rises and in turn shuts the water flow off.
Hope that helps.

Hey Earl,
At what point do you switch from 10/30 to 10/120 on the spraying?
(When you switch over to flowering?)
Do you run 24/0 during veg, and 12/12 during flowering?

Thanks!

love your system, looking forward to #4

Thanks for answering the questions.

I run the spray pump 24/7 until the root are showing out tof the bottom of the net pot and then start having some off time.
It depends on the humidity and the size of the plants.

I don't think turning the pump off makes much difference,
but it does save electricity and wear and tear on the pump.

They can easily go a couple of hours without any spray,
at almost any stage of growth.

Post me a link to your grow.

Hey Earl, where do you get your coco coir plugs? Tried rockwool and did'nt care for the results and hassel. Thanks for all the info.

how do you control the smell of a grow that size?

I get the coco plugs at my local hydro shop.

I don't control the smell.

Did a search on the internet for coco plugs. Came up with zero. Do you have a manufacter name or distributor. Thanks.

The guy at the hydro store repackages them and sell them in ziplock bag with his own label
