[AQUAPONICS] 800 litres, 2x400W, Critical Kush, Spec. Queen

Hello everyone :slight_smile:

I would like to share my lil project with you.
Last year I spent couple months harvesting in Cali and met a lot of interesting people, whom introduced me to aquaponics with words “best weed I have ever seen.” So I knew I have to try it too.

Since my return in Nov it took me 3 months to get to this stage:

  • my room is 95% completed
  • water tank filled - I started to test ammonia, nitrates and nitrites lvls, but Im still fighting with pH (its still arround 8 and I think its caused by substrate (expanded clay) which should have neutral pH, but I think they got me poor batch…:confused:
  • have ~ 35-40 fish in tank - 20x goldfish, 10x tilapia + …

There is arround 800 litres in my fish tank.

For room control I bought electronic control unit for temp, humidity, water temp, water lvl and water pH.

For growing I have 2 beds - 1,25 x 1 m. Height 1,2 m. Depth of bed (for roots) 25-30cm.
Have 400W HPS for both beds.

For walls used diamond foil.

Active in/exhaust of air with passivne heat exchanger Recair RS160.

Next tasks:

  • get my pH on/under 7
  • wait till whole nitrification cycle is finished
  • add water heating

My problem with pH might also cause lack of oxygen and/or not enough water mixing, so I bought 2 water circulation pumps which will mix the water inside fish tank and help to oxygen water.
:slight_smile:

Looking forward to plant first plants.
Will keep you updated.

I’m very excited to hear a fellow aquaponic grower joined the forum. :slight_smile:

That’s laughs. The elusive aquaponic grower. One of the Cannabis worlds most elusive animals. Where will they rear their heads next.

In emergency cases, I use muriatic acid (hydrochloric acid) to bring down my pH.

Things to think about…

Red worms,
Type of feed,
Iron (FeEDDHA or FeDTPA),
other additives for P&K and more,
Worm castings.

Are you planing on testing your nutrients?
Types of filtration?

I am trying to avoid using any chemicals. I got back home after 3 days and my problem is still :confused:
pH 8.4…

Fish seems to be fine tho. Increased oxygenating a lot. Both goldfish and also tilapia already eating.

  • water temp 22.7 C
  • pH ~ 8.4 :frowning:
  • ammonia - 0
  • NO2 > 0.4 mg/l
  • NO3 > 40 mg/l
  • alcalinity - 4-6 dKH

At least nitrification cycle is almost done…

I am going to add some plants to adjust water quality Ceratophyllum and Pistia. I also got Duckweed, which Im goin to try feed fish with. Not only, but combined with pellets or something. I made something like this guy https://youtu.be/4ksnnwxlq1g?t=9m46s to controll Duckweed spreading.

pH problem keeps me frustrated. I bought RO, so I will try take out water from tank and add water from RO, which should lower down pH. Will try it couple times. If pH will keep increasing to same numbers, I might have to remove substrate (expanded clay), which might not be cleaned up enough and could be causing pH troubles. If problems resists, I will be probably forced to change all the substrate and restart the whole proccess :confused: :confused: :confused:

@ryasco @Dumme

On some forums I found out about pH problems with expanded clay.
I have to take out one half of my medium, rinse it again and then soak it in acidic water. It sould rise up again a little bit, so add more acid until it gets stable arround 6. Then put it back to grow bed.

Will see what results I will get from doing this for one bed. After that I will decide what the next step will be.

Very old thread…anyway I was talking to my farmer buddy who has a Koi pond and he wants to grow in his pond…I gave him 2 clones of my Vietnam Thunder Fuck and told him to do a little bit more research on aquaponics…
