If you are talking standard 12x12 room, which will already have a bed, dresser and desk. I think you are in for a rough time. The fish tank(s) will need space, things will need to be cleaned/flushed. It will require some vents and it will make noise. Cost wise you are losing with small space, better off with standard grow methods.

>> No.1304922

>>1304841

It depends on what you are growing. For actual herbs, a small nft with an air lift will work fine and isn't that difficult to maintain. It can be done cheaply on an existing fish thank. My small herb (again, actual herbs) system was indoor near a window that got daily sun and a little extra on a low watt grow light in the evening. The fish tank must be shielded from the sun.

If you are looking to grow something larger indoors with decent lights, I would go with a media filled solution and run a bell siphon or timer (for flood and drain). A cheap rack, media bed on top, sump w/fish on bottom. You will need a pre-pump filter solution otherwise you'll be cleaning the pump constantly. If you're in a confined space, I wouldn't dick with a CHOP system or similar with external filtration - but if you have an entire basement, go for it.

If your goal is to grow plants, adding fish makes the whole thing more expensive and complicated and failure prone. Go to some aquaculture sites; they're very upfront about the fact that it's about learning and balancing the system for the fun of it, and that you WONT get a magical organic perpetual motion machine.

>> No.1306363

In my experience with aquaponics trying to do things on the cheap will result in failure and wasted money. Also the bigger you can build a system the easier it is to regulate/ maintain it. In other words very small systems are a bitch to troubleshoot and correct because there so much less room for adjustments with the system.

I started experimenting with these so i didnt have to clean my fishtanks so often, but its been a lot of fun learning how to propagate plants. ive not tried growing weed in them, i it but I cant see any reason it wouldn't work. You would need a deep bed with a low flow to ensure the roots didnt get too wet. over watering marijuana is all too easy. again clay balls are great for retaining moisture so the plants can just take what they need without being submersed too often.
pic related, its my geto set up. when i build my new fish table cabinet im going to make it look much more tidy so dont judge

currently trying to grow strawberries in my breeder tank but they arnt to happy. i think its the lack of iron in the water. spring onions fucking love aquaponics tho, strongly recommend you put some in new tanks to help whenever the nitrates are getting too high.
also dont forget to learn about cycling your filters, its the same for grow beds, make sure you set up the plants and tank for a few weeks before adding fish. if you have more time stick a dead fish in the water and wait for it to decompose and for the tank to take care of all the nitrates, best way to get a filter running smoothly with lots of bacteria

I recommend going without a substrate in the tank itself, it makes it easier for the filer to suck up the poop, just let the tank develop its own alge carpet and everyone is happy, learnt that in the second tank, i keep the substrate away from the filer in this tank with a piece of sponge and some larger rocks but the placos keep fucking with it

one last thing, these things can be really fucking noisy. i would recommend as quieter pump as humanly possible, often it sounds like I live next to a waterfall, but there are lots of things you can do to quiet a system down. less space between the out flow and the tank water, put the filter on top of a sponge, keep the flow time to the minimum and when you are out of the house ect

fishtank strait to grow bed, through some filter medium to help break down the fish poo.
so water and crap travels through the pump, gets filtered through some course sponge, goes through the grow bed for further filtration and nitrite removal, then dumped back into the fish tank.
my set up adds another filtration step tho, i put a sponge wall to divide the tank and keep shrimp and snails on the side where the water gets deposited and fish on the other.

you just change the height of the siphon to change how much the grow bead floods and drains. pretty much takes care of itself after you get the timing for everything right, i only need to feed the fish daily, top up the water whenever, and clean it once every one or two months. i check the water quality with my kit every few weeks to ensure everything runs smoothly

for first time fish get guppies, make sure to separate the genders with a tank divider or they will breed out of control. mine are in the two tanks separated. if i need more guppies i just put a female into the male side for a week and let he spawn back in her own tank and then separate the new males. ive been breeding them eugenically for colour and for fun. guppies are incredibly hardy fish and will survive most things, are live barers so they breed like rabbits, males are very pretty also


you can use anything for filtering as long as its bigger than the media guards holes, so it doesnt get sucked through the siphon. as i said tho i tub of rocks gets really fucking heavy and can break any tank if not properly supported. cley balls are best. and whatever you use make sure its ph neutral, clay and pea gravel, lava rock or you will kill your fish with ph spikes.

up one pump and gravity keeps the cycle going

not really, you need the tank to be cycled properly, that means that the filter needs to have all the good bacteria before you add the fist. this is step on and can take anywhere from two weeks to a month. the tank and grow bed need to be working first before you add any fish or the ammonia and nitrogen levels will spike and kill everything. its the biggest mistake first time fish keepers make and the most costly

>> No.1308907

>>1308902
*fish
in the case of aquaponics the grow bed is the filter so you need to have your tank and grow bed cycled. best way to do this is to add ammonia into an empty tank and let the filter run. when the ammonia is all gone then the tank is ready for fish. so yes a little pee in the tank and let it do its thing for a while, or pop a dead fish in there. when stuff decomposes or shits/pees it releases ammonia which gets turned into nitrogen by bacteria and then into nitrates that the plants eat

again it all depends on how much time you can give setting it all up. the more time and effort you put in the better chances of success. if you have a friends with a already cycled fishtank borrow some of his filter media and put it in your tank to help kick start the process. they also sell bottles of the good bacteria called 'quick start' but ive never used it so i cant vouch for its effectiveness. oh, also dont overstock the tank, more fish than your filter can handle will cause nitrogen and ammonia spikes and kill everything, start small, 1 guppy for a 1 litre of water in your tank is max, the bigger the tank the more fish you can keep

aquaponics can be daunting as it has both the aspects of fish keeping and gardening but after the initial set up its massively low effort and very rewarding. best plants ive found are, onions, spring onions, tomatoes, peppers, and lettuce

because you would risk over flooding your grow bed if you just left it to gravity. if the pump broke down you would be fucked. also plants need light and having them on top is easier if you have it by a window. also also you would have to have to either have a timed valve or a constantly running pump to get the water flow right. its just a hell of a lot simpler to have the plants on top

aquaponics works because the growbed cleans the water for the fish, its a closed loop system. that water is just going to spike out of control as waste builds up

>> No.1313434

Do you see that little arrow under the growbed? That means water's going out. It's not recirculating

>> No.1313989

>>1313434
yes but look where the tanks siphon is, all the shit in the tank isnt going anywhere its just slowly building up and would not get replaced nearly quick enough to stop nitrogen spikes unless it was constantly ''raining'' (which is still a retarded concept btw) this concept has basically no filter and is just ridiculous for indoor aquaponics

I've seen all kinds of builds from small simple ones with just the plain 5 gallon buckets up to monsters made out of garbage cans or rain barrels with automated light, irrigation, ventilation with carbon filtration to absorb any smell, monitored humidity/temperature/etc.

I think it was originally a solution or alternative to closet growing, with the goal being the smallest grow possible.

For the bell siphons, I cant stress enough how important that bend at the pipe is. It took me a week of me fuckin around with my siphon only to figure out that no bend means the siphon doesn't break

>> No.1314789

>>1314635
or just cut some gaps at the bottom of the siphon bell. you get a millimetre of standing water, but it saves pissing about with the bend

FYI if you want to copy this idea get a cement mixing tray from the hardware store. They are large trays made from black HDPE and they cost like $5 and work well.

If you're using a bell siphon you'll still need a vacuum pump in the event of power loss because you'll lose your siphon. A sump pump with overflow has simpler plumbing and is cheap and works consistently.

>> No.1315098

>>1314310
5 gallon buckets are too small for anything. Use a trash can if anything. A proper grow tent is cheap enough that you should just buy one if you're able. You'll spend more on tape and other bullshit putting a bucket together than you will just throwing $50 at a decent 2x2x4 tent. $25 more would get you a 2x4x4 if you had the room.

You still need the bend for the water to form a lock on the air tho

>> No.1315379

>>1315111
mine doesnt have a bend and works fine. as soon as the pipe starts sucking in water it creates a vacuum and the negative pressure keeps the siphon sucking. when the water level drops bellow the hole in the bell part the vacuum cuts out

I'm growing onions using an led bulb that I can change the color of. I know plants use red and blue light to grow. So my question is, since I only have one bulb, can I set it to purple or does it not work like that?

The light has two internal head sinks and fans. It's only about 25C in there. Also the cabinet they are in is backless for ventilation.

The plants fucking love it. They are getting a healthy DLI of 10 despite how bright it looks to our eyes. My herbs literally grow like weeds and taste amazing.

DLI stands for daily light integral. It is the total Mols of photosynthetically active light that a plant gets in a day. Photosynthetic photon flux (ppf) is the instantaneous quantity of photons in the 400-700 nanometer range received in a square meter per second, normally measures in micromols per square meter per second. It can be measured by a quantum PAR sensor which is like 300$.

mine isn't aqua,but the lighting is the same

>8x15 W chinkshit full spectrum LED (4-6€)
>two cheap used adjustable lamps (50€)
>digital timer (15€)
>cords (10€)

I grow cayenne chillies and tomatoes.
I guess that kush needs atleast as much Lux as these plants.
If you go for LEDs be sure that they have cooler fins. And don't run them 24/7. The """herb""" will grow faster, but the good stuff won't be as potent. Plants need to rest too.

use this calc to determine how much LEDs will you need:

>i think its the lack of iron in the water

The only supplement an aquaponic system needs is chelated iron. Supposedly you can grow barley since it produces siderophores which chelate iron and make it available to plants.
