Water Pump for an Aeroponic System

by Greg

Just about to start my own garden....I am looking at water pumps and cannot decide which one to get. None of them say anything about psi on it, just HP or another unit of measurement. Which pump did you get and where if you do not mind. Your site is incredibly helpful, thank you so much!

Answer: Greg- the hydroponic system I use is a low pressure system and has a low pressure pump. This type of pump measures it's output in gallons per hour (GPH), and would most likely not be suitable for your system. Most aeroponic systems require high pressure to force the nutrient solution through tiny holes in spray nozzles. These pumps usually indicate what psi they are capable of producing, although some may only list their horse power (especially true if the pump was not made with hydroponics/aeroponics in mind).

The Alternative Garden Supply catalog online used to include information on psi for it's pumps, but I just checked and that information is no longer included (probably made it too easy for DIY type people to buy other products). Two pumps they list for aeroponic systems are the Mondi Utility Pump and the TNC Water Pump. These pumps seem to be rated in the 1,250-1,600 GPH range and are all about 1/3-1/2 HP. This would be the size to look at if you are considering picking something up at Home Depot or Lowes.

Another good place to check would be Discount Hydroponics....they are online, but will also send a catalog out to your home if you like. Of course, if you live close to a hydroponic gardening store you will want to stop in there are ask about high pressure pumps....the equipment they have for sale is comparably priced and made just for hydroponic/aeroponic systems. Simply do a search online for "Virginia hydroponic gardening store" and you should get a few different spots.

A couple of other things to consider....you always want to use an in-line filter when using a high pressure pump. This will help keep your spray heads from clogging, but also can prevent your expensive high pressure pump from burning out. A friend of mind burned up a $200 pump the first time he turned it on because he had not cleaned out his homemade system of all the little PVC shavings from drilling the plant holes (and also because he did not have a filter...it all went straight to the pump and blocked suction).

Finally, whenever you use a high pressure pump in a hydroponic/aeroponic system, you need to use a manifold to properly distribute the pressurized liquid through the system. Be sure to check that page out if you have built this system yourself. I sure hope this helps!

Hi everyone, Jason from Jason's Indoor Guide here. When I got started with hydroponic gardening more than 24 years ago, my first garden used rockwool cubes and B.C. Nutrients....and I remember thinking to myself yeah, sure, there may be a lot of advantages to gardening with hydroponics, for example there are very few pest problems, therefore very little pest control, no weeding, no plowing or tilling the soil, no soil testing or having to add things into the garden soil, no watering the garden....but for someone who just wants to grow their own vegetables and have more control over their food supply and the quality of the food that they eat, the cost of constantly having to buy grow media and hydroponic nutrients makes this an expensive hobby for most people...

Epic Nutrient Change

I suppose when you take into consideration how much money you save NOT having to buy food at the grocery store, it is surely cheaper to grow your own food hydroponically even with the cost of high quality nutrients. Nevertheless, I didn't have a whole lot of money to work with and I needed to make my efforts as affordable and effective as possible....and in the last 24 years I HAVE learned a thing or two!

As you browse through Jason's Indoor Guide, you will notice all of the systems that I use personally are homemade systems. As I got 3 or 4 years of experience under my belt, I quickly adopted a preference to standing water systems and systems that use expanded clay pellets or lava rock, because the media is re-usable and it eliminates a huge operating expense. So once a hydroponic system is built, garden maintenance is minimal- check and adjust the nutrient solution daily, and to change it completely every 2 weeks....and the biggest operating cost is the hydroponic nutrients. (and the electric bill, lol)...

Homemade Cloner

And, regarding the cost of the nutrients....I experimented for about 3 years with making different compost teas and nutrient teas, but there is still a lot of expense $$$ associated with making high quality nutrient teas....like kelp meal, liquid seaweed, rock dust, bat guano, un-Sulfured molasses, worm castings. You can eliminate a lot of this expense by becoming an expert at making high-quality colloidal humus compost, and use your properly made compost as the basis of your hydroponic nutrient solution.

Unfortunately, I have been gardening for over 24 years and I have only just recently mastered this difficult skill....and even then, only because I happened to find a very easy to follow, high quality technique and decided to follow the instructions to the letter. I produced more high quality compost in just one week than I was able to use in a whole year! If you can master the technique, I highly recommend it. It is one of the top 3 things you can do to increase the productivity of your food production efforts, while at the same time decreasing the amount of effort required to grow all of your own food, and decreasing the total cost of operating your food production system.

And when I say decrease operating costs, I mean decrease them to almost ZERO, especially if you are producing your own nutrients...

High Efficiency

The ultimate solution to eliminate the cost of your hydroponic nutrients: Imagine a hydroponic system that does not require you to buy any nutrients, does not require you to make your own compost, and does not require you to brew your own nutrient tea. Seriously! No cost and no effort as far as providing nutrients to your plants! Plus, at the end of the gardening cycle you harvest all of your garden vegetables, PLUS YOU HARVEST FISH from the system--->

This solution is aquaponics. If you are serious about producing all of your own food and being self-sufficient, this is the ultimate solution for reducing expenses (as much as possible), reducing the total amount of work required, and maximizing the productivity of your gardening efforts. I have been gardening for over 24 years, and it is the perfect food production solution in my opinion.

Produce garnden vegetables AND fish together. Eliminate fertilizer costs!

Besides mastering how to make high quality compost, learning aquaponics is one of the top 3 things you can do to increase your garden productivity, reduce your total costs, and reduce your total work. The product that I learned from is called Aquaponics4you. With all of my hydroponic gardening experience, the first time I came across the Aquaponics4you product I knew immediately that it was something very special! Place an aquaponics system outdoors and use the sun instead of grow lights, and you have reduced every garden expense to nearly ZERO!
