Aquaponics - let the fish be your nutrient!

Hello y'all!


I have been pondering this setup for quite some time, and is starting to puzzle the pieces.
After reading up on ventilation I found myself a little short of expertise, so to speak.
If anyone out there want to come to my humble setup rescue and look over the number, I would be much obliged!


This is where I'm at:


Growroom!-!


2.5m * 4m * 2m


10m2
20m3


Starting with 4* Gavita PRO 1000 DE EU
http://www.gavita-holland.com/index.php/products/gavita-power-line-high-performance-lighting/item/gavita-pro-1000-de-eu.html
" * room for upgrades = 2 extra PRO 1000 and 2 Gavita PRO LEP EU
( http://www.gavita-holland.com/index.php/products/gavita-power-line-high-performance-lighting/item/gavita-pro-300-lep-eu.html ) "




Correct me if I am mistaken, but could my ventilation calculation be something like this:


20m3 * 60min = 1200m3/hr <- this is what I need to replentish the room completely every minute without any filters or other
interferrences.
I have read that it's "recommended" to replentish the room every 2-3 minutes or so.


If so I take in to calculation of
8 1000w with a boost capasity up to 1200w (15% for each 1000W)
1 filter (20%)
10% for extra juice
0% for ambient temperature = aircon


I found this guide for ventilation, which is in cfm, so I was not sure if the calculation would work with m3, prolly not.

After converting my m3 to cf and adding the % I arrive at 587cfm minimum exhaust fan needed.
Does this make sense ?


If so, I was thinking of running this fan:
Manrose MAN280M

with this filter:
Phresh 1000m3
http://www.tienda.2odd.es/index.php?id_product=52&controller=product <- cm/m3
http://www.phreshfilter.com/about/size-selector.aspx <- inch/cfm


I know that the fan is a tad over the recommended "maximum" from Phresh side, but I could always trim it down.


I would love to get your two cents on the matter!
 
Hello everybody. I just wanted to share with everyone my aquaponics grow. This is my first time growing cannabis. But have extensive experience in organic gardening.

Anyway. I got some "kush n cheese" from a friends friend. I got two plants. The runts of the runts. They were grown in 4 inch rock wool cubes. They also came with thrips and the growers treated for a fungus. I took the plants and soaked them in a 5 gallon bucket, essentially flushing out all the hydro nutes, and fungicides that would kill fish and bacteria. The girls were pathetic. Purplish stems, serious nute lockout image.jpg

I have a 170 gallon aquaponics system using bell siphons for 2 15 gallon grow beds. I'm now running a 400 cmh and a 400 hps in a vertical grow. My system wasn't fully cycled when I got the girls so initial growth was quite slow. This is them day 1 and day 38. A few days before flower I treated the plants with azatrol and done pyrethrin spray from safer. Bye bye thrips. I never had an ingestion but they drove me crazy. I would literally just stand and stare at my plants till I saw one and I would pick it off. Annnnnoooyyyying. Anyway, here they are. 38 daysimage.jpg

They soon went into flower after that. At 16 days, things are looking great! Slight wind burn. But that's it. Water temp is 71, and canopy is 76. I trimmed all fan leaves that block light to buds. There are so many bud sites, it's crazy. But I have trained and pruned so I shouldn't get any of that popcorn bullshit. I also added some cilantro and basil to the room for shits and giggles. Maybe it will make it taste better. I will keep this updated. image.jpgimage.jpg
