Fish in Hydro

[freddie]

I'd love to grow like this. Veges too!

Hey you guys are wackier then me!

 

The main point I gather is no nutes, you feed the fish, they poop and feed your plants. The more plants you want, the more fish you have to have. Don't be throwing any goldfish into your nutrients unless you want to totally cantaminate things with a dead rotting fish!

 

So why not go one step farther and put a rabbit cage above the res/fish tank? The rabbit poo feeds the fishes which feed your ganja plants. At the end of the day, you can smoke a doobie and sit down to a nice bowl of rabbit stew while watching the fishes swim around fighting for the latest piece of rabbit poo falling from the sky.

 

Sorry... I'm a little stoned,

That was a great laugh, thanks! ^^

Fascinating topic, I saw something like this on the new inventors too. I'd like to try it someday but First I must master the basics of Hydro. When I get a place of my own that I can set up my dream hidden basement Grow room then I might look into it seriously. Also there is a hydro store nearby that sells aquaculture supplies so I reckon they'd know a fair bit about this too.

Its fancy name is Polyculture.

Or yea Ive seen it listed as Aquaponics, but I always thought that was spraying the roots of a plant.??

Nah, that's aeroponics... Too many ponic words flyin around IMO

hey this is something that wanted to do after reading about it in High Times mag, the dude that was involved with the berry strains, had some sort of setup in an appartment where the fish made all the nuets for his plants, but the nuets were filtered from memory to keep the solids away from the plants, and he only used live food to feed the fish, something to do with taste of the buds,

Aquaponics is easy, as the system tends to buffer itself. I have no experience with hydro, but have had an aquaponic system running for about 9 months, not mj though, just veges and herbs. In that time i've only lost a handful of fish and only needed to test the water a few times.

 

 

i think this is sick, leave the little fish alone. do you think that it would wont to live in a hydro res ?. for one, in hydro PH can go crazy and the little fish wil die.

 

2, i dont think that a fish could ever poo anuff to grow the size buds we are all after.i think this stinks

I definitely wouldn't advise putting fish in a hydro res biggerbuds, but aquaponics is not about that.

As for fish pooing enuf to grow buds, you should check out some of the threads at icmag.com.

I've seen pics on backyardaquaponics.com of fruiting pawpaws growing on fish poo, not sure in they're adding other nutes, but some of these people have 50 or more silver perch in their system that's a lot of shit!

Surely they can't get all the nutes they need from fish poo? What about changing over to flowering cycle where you need more phosphorus and potassium? I'd be pretty pleased if I could get this to work but I reckon you must have to add something. Would the fish be ok if you added stuff? Probably not.

Welcome to OZStoners john

 

The fish shit(50% ammonia) is converted by nitrifying bacteria into nitrite and then into nitrate which plants can take up.

 

I have noticed deficiencies in some of the different plants I've grown in my little system, but this is mainly due to not having enough fish shitting!

The ultimate way to get certain nutrients into the system is via the fish food used, ie a broad diet for the fish should provide all the nutrients needed by the plants. However, I have added small amounts of guano(P), kelp powder(K & trace elements) & molasses without hurting my fish.

 

The big risk is at harvest time. If you simply removed all plants from the system, it would overload with nitrate, because the plants would no longer be removing it from the water. To get around this is simply a matter of growing plants at various stages of growth at one time. This ensures a more balanced load(some vegging, some flowering) and means that harvesting only removes a percentage of the plants in one hit.

 

If you want to learn more or just to see what aquaponics is capable of, I highly recommend checking out backyardaquaponics.com and the 'Organic Hydro' forum at icmag.com
