Aquaponics - let the fish be your nutrient!

Everything I hear about vegetables is that they taste better than soil grown, even organic soil, and way better than hydroponics (synthetic).

If only I could afford the apache.

I bought a light from China. Lasted a year and half :/ They will send me a replacement part with my next order. I need a new light anyway and cross my fingers the failure was a fluke.

I've read that aquaponic systems take 6 months to a year to "mature" before being able to handle big feeders. This is information about growing tomatoes versus lettuce though.

My next grow was planned to compare this grow with a grow using only fish pond water. But the led died halfway through this grow. And even though I was feeding and watering less the buds were thicker and denser than the previous round. Not sure why.

Why are they growing in a tunnel? And what is the proposed energy source on mars to power anything? Not sure why I hadn't wondered that before.

Look into barley for stopping algae. I'm not sure how much algae bluegill will eat. No particular reason not to use them that I know of. In a well balanced system there's unlikely to be algae as there is no excess nutrients. Also if there is minimal light leakage there shouldn't be much.

I've not seen any aquaponics material talking about ppm. Usually its ammonia, nitrite, nitrate and pH. I think you may run into issues with the sprayers clogging unless you have a really good screen on the pump. I wouldn't want to spare the room indoors for a settling tank and what not. My future plan is for a deep water trough so I don't have to worry about it too much. On the other side, what ever comes out of the settling tank can fertilize potted or in ground plants.

I would use the kelp as foliar feed rather than in the water as recommended by the local aquaponics store.

I've also heard that one shouldn't use oils, even natural oils in ap as it can coat the gills and suffocate fish. Maybe more of an outdoor issue. Also read not to use soap or garlic. I've not tried any of it myself.

Tilapia need to be fairly warm. I noticed a number of articles saying tilapia have either too much bad fat or omega 3 and 6 in bad proportion. I'm not sure if that's all tilapia or just the crap from China.

As for pH adjustment use calcium carbonate for raising. The fish and bacteria will slowly lower it naturally.

Since you've proven to be knowledgeable, obviously, :P what would be your input on the idea of using bluegill? There's no extremely important reason for considering bluegill. I just like the idea of tossing a line in my own pond in my own yard to catch my own fish for my own crop. You see? :3 so yeah, they'll eat just about anything given to them, which would probably be regular fish food with the occasional insect/grub. For a medium sized (10-plant/bucket) aeroponics, but not true aeroponics, just one reservoir with a drainage and spray line to each of the 10 buckets using just those cheap 180 degree sprayers, I'd probably want to have a ppm residing on the higher end of the recommended levels (within reason and preparation for it to rise) since the roots won't be constantly exposed as per DWC. And if I'm not mistaken, bluegill can take SHIIIITS. My biggest concern: what should I use to control the algae? Bluegill are known to sometimes eat smaller fish and I'm afraid they'd at least kill, if not just eat, any small type of algae decomposer.
Bluegill can grow quite big, depending on their habitat of course.
Why not test out Silver Perch if it is available in your area, they are big algae eaters, regularly found in moving water but been seeing this fish recommended on several AP info sites.

I currently have two catfish algae eaters and two smaller unknown algae eaters, six comet goldfish and two black moor. Algae is kind of a issue in my system, so I am building a light blocker on top of the grow pots. Also figuring out a screen to put over the drain tank which the pots stands in, kind of looks like the algae starting to build up in the root system that grown down to the fish tank there.
My drippers need a little poking everyday for not only the algae but also fish poop, this I think I can reduce with the "sunblock" and also perhaps with a bigger water pump.

My system and others that I have seen on this and other sites are producing amazing results in 1-2 months.
This was 4 weeks-in with a new system, 3 week old basil cutting, that was 5 cm when planted:

Interedesting, do tell more :D

Read on several AP sites that the liquid seaweed extract can be added directly to fish tank as they do not harm the fish at all.

The neem oil is going to be sprayed or added with cloth on the leafs and will kill the pests as it attacks their nervous system, without ever harming the plant, so no biggy there.

DIY organic pest control will also be added directly to the plant leafs, so should not really be any fish harm here.

i thought people did foliar feeds selectively to fan leaves during flowering in aquaponics because of its high N ratio and low K ratio? just wondering! https://www.rollitup.org/organics/636057-recycled-organic-living-soil-rols.html This is where you can find info on aloe powder and coconut water, hope that helps with the flowering issues somehow and u can incorporate this into the system.
Not really that experienced, so can't reply in much depth on the foliar feed, what I am about to do have more to do with the pests that are eating the nuts of my precious leafs :cuss:

Nice, will read up on the alo y coco!

My outdoor veggies are covered in spider mites and aphids and I'm afraid to use any of the oils and such on them. But out there rain will make it run off into the fish water.

Soo where's the picture of your fish, and what did you germinate? Cause I know you ain't germinate clones.
Who are you talking to ?

I feel you brother, this is the first time I have had any issues with grow what so ever, kind of bummed out that it had to come now, with the first AP run and all :D
But hell! It's not like you never get any pests unless you run a closed environment grow.
..if you take a gamble on the weather forecast you should be able to go for some neem oil.
I am not going to spray it, but take a sponge and tap tap tap!

Just sat up some glue traps for the flying bastards in there, added some lemon, chili, garlic, baking soda mixture to a couple of leafs.
Will see tomorrow if the mixture is good for the whole plant.

Germinate clones? I don't know how he has so much rep.

I never had a pest issue indoors. I had moths get in sometimes but they don't do any damage.

I picked up some lady bugs but guess they'll have to wait until tomorrow night to go out

Do you live in the states ?
Found out that the only possibility for me to get either Hypoaspis miles or lady bugs in spain, is to order it from Belgium, and since they come in larva form, they need to be shipped in special package that can hold them in their 10-15 celcius degree survivor temp, bah! Will cost a fortune, just had a talk to a guy at the grow store, he "kindly" suggested that I should order some when it is not so hot, ...like I was planning to get bugs :dunce:

Yes I live in the usa. Lady bugs are a common bug for any organic place to carry. They are in adult form. There are several other bugs I want to get but they're pricy and have same issues shipping as you do. I plan to grow flowers and such to attract beneficial insects next year

Yeah, haven't really seen them around here, tho.
Spain is a couple of years after the rest of us as far as internet solutions and availability goes.
Mom and pap stores everywhere, closing the store for 4 hours in the middle of the day, so on and so forth.

I am going to buy up on the stuff as soon we move in the the new house with garden, garage and greenhouse.

Looks like the mixture was up to the plant liking, no effect on the leafs what so ever.
Added a half ts of Neem oil and just went crazy!
Also cleaned the drip system and created a buffer over the pots and around the gaps, to minimize the algae build up.
The drain area that the pots sit in have some big algae-gel-slubs, dunno if I should just remove it or leave the system to take care of it self.
Algae will die / slowdown without direct light, ye ?
pH was down at 5.6 today, tossed in some pulverized eggshell, 4 hours later I am now seeing a .2 bump in pH.
Pretty cool how the fish don't even try out things they should not eat, ..cleaver fishy!

New water test today, and the score is...
Ammonia: 0.10<
Nitrites: 0.01<
Nitrates: 1<
pH as stated up to 5.8
PPM 470

the poor light makes it seem more orange than it is:

On a downside, I am seeing some new tops having a bad time at the one in the left back corner, and some more rust buildup on the one in the right back corner, also some yellowing lower leafs on all of them.
This stuff all came tumbling down at the right moment, flip time..

Looking for some input on a couple of things here.

So I sprayed the whole canopy with my homemade pest control, have not seen anymore Thrips crawling around.
The flying bastards are still around, tho.
I recon our new and improved medium protective shield they would find it more difficult to lay their nasty eggs.

The leafs that have severe "rust" damage, should I simply cut them off ?
Could these leafs still be beneficial to the plant in their condition ?
Would they simply get worse, as it kind of looks like ?

Was thinking of making a mixture containing this, and also adding some boron.
Maybe also adding some aloe and cocowater, what do you guys think ?

Awesome, thanks! :P I just kind of figured there wouldn't be enough algae to really feed an algae eater big enough to fight off evil bluegill. It probably is best to just stick with the smaller stuff, but what the hell, right?

By the way, I feel as if this should be eventually stickied. I'm pretty sure there isn't an Aquaponics sticky yet because I've extensively looked :P so yeah. Aquaponics is ON THE COME UP!
