Cheers.

Fix the sand bed surface (ridge/furrow)  after removing the crops, so that the flow patern gets right again

cheers

Hi everyone,

  • After growing products like, lets say tomatoes, which have a large root system. In my mind it stands to reason, after removing the plant itself you be meticulous in removing the root mass from the grow bed. Is it necessary and why? If it is necessary, do people have any easy way of doing this, or is it just one of tedious jobs, with no better way, which has to be done?
  • At the time of removing roots, providing it is necessary, what other sand/sand grow bed maintenance should be done in order to prepare for the next growing season?

Cheers.

The root mass of tomato plants grown in sand is much smaller than those grown in gravel.  The plants are easy to remove when it's time to replace them with other plants.  Just remove any visible plant debris and, as Ande has suggested, you simple reshape the furrow ready for the next planting.

Hi again,

We have a hot dry summer, occasionally exceeding 40 C for a week on end, regularly 30 to 38 C and a cold wet winter. We don't get snow, but it can get wet cold and windy occasionally, similar to the mediterranean climate, therein lies the problem. My tanks will be outdoors and so will my growbeds. I have succesfully grown Barramundi through the winter, but do not wish to do that again but have been also successful in doing 6 months barra and six months rainbow trouts.

I would like an all rounder (if there is such an animal) which does not require to much water temp management, and is easily available. with it'[s food also being easily available.

  • What fish do people suggest?

On fish species question,

While theoretically any aquatic organism can be raised in aquaponica, in practice, it is dominated by just a few.  

The big four in aquaponics had been (as per my readings) Tilapia, Hybrid Bass, Rainbow Trout, and Yellow Perch (yes, depending on climate) but then there are many other species of aquatic organisms have been raised.

We have been trialing on five other species and raised some of these very successfully (in India.)  Here is a list.

- Asian seabass (barramundi)
- Freshwater shrimps (macrobrachium rosenbergi)
- Carps - common carp, silver carp, and grass carp
- Pearlspot (my state fish)
- Climbing Perch (Anabas cobojius/gangetic bananas), a brand new species under trials at some of our aquaponics sites.  Results are yet to come but then looking at the current stats I would call it the future fish best suitable for commercial aquaponics.

Hi BD

I think , maybe your last Q on specie choise(s)/feeds, relates more to your spesific system/climate rather than being a iAVs Q ?

so I suggest moving it ,including Mattyogas answer ,here :

What say you ? :D

 

cheers

Yeah, I'm happy enough to have those posts moved to my thread, if you wish Ande...I don't mind if they are here or there...

Cheers.

To save us both some time, could someone please reanswer my question, plus if there are any different answers people have now we are sometime further on, could you please post them here.

Cheers.
