  1. Hi VKN + 1 Been thinking a lot about you, when watching the news cheers
  2. Hi mamakat Welcome to APN/HQ cheers
  3. Hi vkn I'm not familiar with bottle gourd, it's not grown around here but you can buy them. Eating the fruit meat, is known as a lactation remedy here ? Using google I found this spooky news article from India, amongst numerous health benefit promotions, on the fruit like this article cheers
  4. Hi fm7777 Welcome to APN/HQ I would stick to the blue drums (price), If you look in the comments (scroll down) in this link you will get a flow capacity figure on the blue drum. You should also look in to multiple outlets of the fish(shrimp) tank, bottom drain/midwater pickup/surface skimmer. Use the RFF primarily on the bottom drain with aprox 20% of the total flow (increase at feeding time). Also remember until the filter is drained of solids, it represents a potential bio foul hazard, with the solids standing in the water column. IMO you should drain out the filter(s) as daily routine in any high density setup. If that is a practical problem, maybe look in to rotary drum filter or parabolic screen filter, where the solids are automatically taken directly out of the water column, as it passes thru. There are multiple threads on diy versions of all the filters on the forum, also koiphen forum has a great diy section cheers
  5. Hi Travis Welcome to APN/HQ Exciting operation you are taking on I wish you the best of luck on this journey There is numbers on tomato yield to fine in studie/doc. #5 in this post Also you should ask the Q's in separate posts, some forum members never read the welcome wagon forum, but will likely read posts with the theme (questions) adressed in the post headings cheers
  6. Hi HamiltonAP Welcome to APN/HQ Nice mess you got hope you find time to share your upgrade, as it happens. cheers
  7. Hi I thought I'd post a nice video to clear up some misunderstandings elsewhere on the forum, enjoy VEGETABLE-PORN MYTHOLOGY: OEDIPUS REX AS TOLD BY LEGUMES OCTOBER 07, 2014 BY FAENA ALEPH POSTED IN: ECCENTRICITY Warning: this piece contains scenes of vegetable sensuality. cheers
  8. Hi A special issue with 12 articles on aquaponics Water is an international peer-reviewed open access monthly journal published by MDPI. Quote : Special Issue Information Dear Colleagues, Aquaponics is an emerging method of local food production worldwide, using closed integrated production systems to grow vegetables and fish in a variety of contexts, including urban environments. It may be defined as an integrated, quasi closed-loop, multi-trophic food production system, comprising a recirculating aquaculture system (RAS) and a hydroponic unit, ensuring high levels of water reuse and nutrient recycling. Aquaponics is typically a multidisciplinary topic, covering several domains, such as aquaculture (fish feed, fish health, fish yield, fish wellbeing, sludge waste, sludge mineralization, sludge reuse, etc.), hydroponics (plant yield and growth, plant nutrition, plant nutrition through sludge recirculation, plant protection, etc.), water (water quality, water waste, water recirculation, etc.), microbiology (biological properties, microbiota characterization, population dynamic, quorum sensing, etc.), engineering for industrial and domestic uses (elaboration of production systems, sizing, modelling, monitoring of the systems, monitoring of water and water quality, automation, etc.). A successful development of aquaponics could insure, in the next decades, a substantial part of human food while having a neutral impact on the environment. The aim of this Special Issue is, therefore, to summarize and disseminate recent scientific findings in aquaponics. A special attention will be paid to scientific progress leading to the development of a sustainable production system. Prof. Dr. M. Haïssam Jijakli Guest Editor full issue. 1.

  9. Hi vkn Well, I would have found it strange, if there indeed was references to Mark's works, when it's not relevant in the specific studies. I don't understand your point ? cheers
  10. Hi again vkn Wether they are familiar with IAVS or not, I wouldn't know ? They are clearly familiar with media beds, as a HP method. However, I don't think media beds are used in commercial settings, in tomato production, in Europe ? If so, it would most probably be with LECA (Light Expanded Clay Aggregate) in the media beds. My guess is, that they didn't find media beds relevant, in their tomato yield study ? The study presented here compares tomato yield, morphological (external) and biochemical (internal) fruit quality, and overall tomato plant vitality from three different HP systems (nutrient film technique, drip irrigation system, and floating raft culture) and examines the distribution of nutrients in different parts of the tomato plant. Three replicate AP systems were set up, each incorporating the three different HP systems coupled with a separate recirculating aquaculture unit growing Nile tilapia. IMO it would be odd to mention/refer to IAVS/MarkMcM in this context It would be cool if you had the opportunity to set up a study like that after all you are the only commercial IAVS operator around that I know of cheers
  11. Hi vkn See the heading : Tomato Productivity and Quality in Aquaponics: Comparison of Three Hydroponic Methods The study does not include any kind of media growing methods cheers
  12. Hi phri I had read a few of them myself, but it's a good collection of peer-reviewed articles on aquaponics. There is also this aquaculture series, 4 articles on "Taxonomy of Means and Ends in Aquaculture Production" that you might find useful, from MDPI enjoy cheers
  13. Hi all To day is cheers
  14. Hi rhubarb harvested to day Got a good deal with my daughter in law, I give it all to her, I get some in return, in the form of cake and jam cheers
  15. Hi What a tree(s) Quote : Sam Van Aken, an artist and professor at Syracuse University, uses "chip grafting" to create trees that each bear 40 different varieties of stone fruits, or fruits with pits. The grafting process involves slicing a bit of a branch with a bud from a tree of one of the varieties and inserting it into a slit in a branch on the "working tree," then wrapping the wound with tape until it heals and the bud starts to grow into a new branch. Over several years he adds slices of branches from other varieties to the working tree. In the spring the "Tree of 40 Fruit" has blossoms in many hues of pink and purple, and in the summer it begins to bear the fruits in sequence—Van Aken says it's both a work of art and a time line of the varieties' blossoming and fruiting. He's created more than a dozen of the trees that have been planted at sites such as museums around the U.S., which he sees as a way to spread diversity on a small scale. cheers
  16. Hi bcotton How much power does it consume ? cheers
  17. Game on cheers
  18. Hi Gary I belive the "official " season in my location now is set at +/- 175 days, it keeps getting extended, do to global warming. The public farmers guide (2015), from the closest measuring station to my place (10 years average) is this: "Middel temp. over 6 °C from April 22. Middel temp. under 6 °C after October 27." However there is fairly high risk of frost nights, up til mid May, and after mid September, so you have to consider that risk when choosing crops, sowing and harvest times. And/or cover the crops outdoors that is sensitive to frost. cheers
  19. Hi My new ducks dissapered without no trace ? So time to try something new to me. I'm having a go with Coturnix coturnix Just loaded my incubater with 150 eggs so we'll see how this goes exciting
  20. Hi What a great capture cheers
  21. Hi Sagir Welcome to APN/HQ Be sure to check out vkn's thread coming from India cheers
  22. Hi vkn When I build the hugelbed 4-5 years ago I used weeds/twigs/branches/cardboard/fresh horse-manure/aged humanure/woodchips/coarse builder sand/clay/seaweed/hay/bog , randomly, as filler between and over the logs. After planting the asparagus 3-4 years ago, I have used a mix of household compost, shell sand, bladderwrack (seaweed), wood ash and grass cuttings as soil cover in addition to the quail deep litter. I have it all for free on my land, just a matter of collecting it, and try to get the "right mix" It looks like I'm getting there, the plants are really taking of this year cheers
  23. Hi again Here are all topics posted by Jeremiah a forum member ( @Cold Weather Aquaponics ) they might not all be relevant to your frost "problem" but I think for the most they are cheers
  24. Hi Soko Welcome to APN/HQ What you suggest has been discussed in a few threads/posts. I would not recommend it other than in existing ponds that are "over fertilized" (exposed to runoff etc.) for clean up purposes . Your plants will suffer, unless you over crowd with fish, and then your fish will suffer. Plants are hard to handle (reach) if the rafts are to large, and if "to deep/wide" pond/tank, it's difficult to handle the fish (harvest) clean out the muck from the bottom etc., so there is a number of reasons, this method is not commonly used. Here are two threads on floating islands/rafts that touch upon your idea. I would recommend that you rather look in to cold water aquaponics cold in content titles and body gave 18 hits in the forum search function There is a lot more on cold climate discussions, tips and ideas on how to deal with frost etc. as many members have to secure against that, and overheating(flip side of the coin) which also is partly solved with insulation active/passive integration etc. cheers
