Hi @rice555,

 

I'm currently weighting and mixing my own nutes. I do it a bit small now, but researching first hand because I'm planning to scale.
Currently, I'm using about 100L of nutes per week. I'm planting leafy veggies, and willing to add fruity types, too.
For forwarder, it's easier as I already had one to forward from Thailand into Cambodia with any documents prepared.
My main concern is the nutes supplier if I'm going to scale because it's damn expensive here.
That's why I need to find a solution with this.

 

And, I also need lots of Nitric Acid for Ph Down, too. It'd be great if anyone could suggest.

Thank you!

So question.  Where do you get the supplies for aquaponics? These require fish and a pump system for moving  the water.  

This forum has almost everything but this information,  so it seems.

Yes I have been quite pleased with higreen so far. If anyone needs ph or ec meters I would recommend aliexpress.com they are much cheaper than buying here, get some ph buffer powder too to calibrate your ph meter. The cheaper ones are not waterproof so I buy two of each to have a spare in case one dies.

I don't bother to calibrate my Ph pen, I just stick it in milk (Ph 6.6) and note the difference.

Currently it reads 7.2 in milk ...... so I just take 0.6 off all the readings.

Pumps for an aquaponics system are available from aquarium specialists or places like Global house/Dohome, which is also where you could get the various pipes and fittings. Get some second hand IBCs and cut them in half for flood and drain media beds, or whole for the fish tanks, try Facebook marketplace or a local used drum seller. Clay pebble "poppers" media is available on lazada or at Global House.

I'm sure there would be somebody selling Tilapia fingerlings near you, where ever that might be.

If I might add, Many videos on the subject on Youtube, watch a few, get some ideas, settle on a game plan, then you will know what components you will need, as said all these components are readily available at different places. But Mostly you will need a pump (lazada ,or other places) an PVC pipes, fittings , and material for frames. (any DIY store)

Good luck

Post any ideas , I also have a small Koi pond and was thinking on a similar project, which is why I am following this thread.

Where can I get second hand IBCs in Chiang Mai, does anyone know?

This post was initially written in another location as an answer to questions about my system. I have re-posted it here as it may be of use to others interested in Aquaponics.

 

I am no expert but I can share what I have learned. I initially came across the idea of aquaponics on YouTube, quite by accident. Intrigued by the idea but lacking any kind of farming skills, it was a big leap of faith for me to just jump in. I read a couple books on aquaponics but they weren't of much use. Watching Youtube videos was probably the most instructive for me. Bigelow Brook Farms is one of the best on YouTube. He is very thoughtful with his designs and has some great instructional videos.

 

The pictures you saw were of our initial aquaponics build. It worked out better than expected and generates about 1000 THB a week in excess. It was never designed to be an income but more of a learning platform and a source of healthy organic food for my family. In terms of maintenance, it requires one full day a week and an average of about an hour a day on the other six days of the week for one person to maintain.

 

We are now building on the knowledge we have earned with a larger, more commercially oriented aquaponics design. This one will have two 2,000 liter fish tanks as the original one did but a larger filtration system and no media beds. It will have three deep water culture beds (DWC) instead with some 4,600 planting spots. We anticipate being able to harvest around 1,000 leafy greens such as Red Oak Lettuce, Pak-Choi, Ka-Na, every week. In a footprint of 6 by 25 meters.

 

I haven't kept close track of the building expenses but to the best of my memory we paid roughly:

43,000 THB for a local welder to fabricate a steel pipe screen-house structure

9,000 THB in rock for a base

8000 THB for two fish tanks

5000 THB for an IBC tote and some 55 gallon barrels

10000 THB in metal electrical conduit

10000 THB Polystyrene 

8000 THB for a roll of pond liner

2000 THB for a pump

10000 THB for 4,600 net pots

10000 THB for other misc. parts such as PVC tubing, PVC fittings, bulkhead fittings, and the like

 

I still have a few items to purchase like some air pumps and the screen to cover the screen-house but we will probably have 150,000 THB into the structure. The ongoing expenses are seeds, fish food, electricity and optional amendments such as iron chelate or soluble kelp. I am guessing roughly two to three thousand Baht a month in operating expenses.

 

I am leaving the door open to ultimately fit the system with solar power for resilience but that is down the road.

The pictures of the original aquaponics structure are on page 13 of this thread. These pictures above are of the new aquaponics I am building. Yes, I use Tilapia and a few crawdads.

I would like to build a small NFT system to grow veggies for my household, but before I do I have two questions I have trouble finding the answers to:

1. Water temperatures. The past days I have kept a jug of water in the crawl space under my house where I intend to keep the tank. The temperature of the water in the jug has been fairly steady at 28-29C during the day. Once this water starts circulating through the NFT setup I am sure I can add another 1-2C degrees to that. Is this too hot to grow with? I am mostly looking to grow leafy greens in the system.

2. Rain and nutrient dilution. I will keep the system outside. I would rather not construct a roof/awning for it as it is unsightly and will cost more money. But would that give me problems with rain entering the system and potentially diluting the nutrients?

I can't give you data to support my post, but I have a micro irrigation sprinkler system and the timer/water valve switches on at 0300hrs and 1500hrs. At 1500 hr the timer is in direct sunlight and the initial water flowing thru the irrigation pipes is very hot, but hasn't seemed to have effected the plants.

I think you should try and keep rain out of your system. You really need a closed system to be able to control what goes on. If you have problems you're not going to know if it's from the rain or something else.

Hullo again and looks great. I can't remember, but did you fabricate the windows in the fish tanks yourself? I was talked out of windows as too difficult and leak.

Can you give me more details of your sump tank? Looks like you built a cement tank with those airrated blocks that you put the IBC tot in. What's with the black plastic covering the IBC TOT and the other tank inside the Tot. Can't wait to see your setup. Nice work. 🙂

Yes, I ordered a couple pieces of Polycarbonate from Techi Polymers Co., Ltd. in Bangkok, cut the holes in the tanks, drilled the screw holes and bedded the windows with Polyurethane calking. They will never leak.

I dug the hole, poured a floor. built up the walls with normal concrete blocks, poured more reinforced concrete in the void between the block walls and the walls of the hole. 

 

The IBC tote is painted black on the top to stop sunlight from supporting algae. Additionally, I used air blocks to raise the height of the IBC tote a few inches to match the height of the DWC beds. I will also make a shelf for the pump with the air blocks.

 

Just got all three of the DWC's skinned out and filled with water to test. I need to plumb the DWC drains into the sump, plumb the pump, and finish the electric before I have water circulating. Hopefully in the next few days. The wife is working on getting the screen to cover the screen house structure but that will be a week or more before we are ready to cover it. I am anxious to get water circulating because it has to circulate for a few weeks before we add fish and plants.

Aquaponics or hydroponics? The rain helps to top off evaporation from my aquaponics system (photos on page 13 of this thread) with no concern for dilution. It may be different for hydroponics, I don't know.

 

The heat has definitely slowed down production in the last month or two but leafy greens still grow, albeit less robustly.

Thanks for the idea of extra room in the sump for the pumps. Will make a concrete enclosure like yours. 🙂
