  2. Hi AtomsDad and welcome to APN, Cheers.
  3. Last week
  4. Hello AtomsDad Welcome to APN/HQ cheers
  5. I'm an early retired welder (work injury) turned small time - family run - market farmer. Started researching aquaponics, then started remodeling the greenhouse; now I'm here, lol. Hello everybody!
  6. Another Vishukkani gift received.. This is from Mr. Jayakrishnan, Nanniode Aquaponics, Palakkad, Kerala
  7. Dear All, Season's greetings - Vishu, Baisakhi, Bihu, and Puthandu! Every new year brings with it golden opportunities. Opportunities to give up the old and embrace the new. Opportunities to start over and perform miracles. In this time of new beginnings, irrespective of the cultural boundaries, we at NARDC wish you a good harvest of joy and prosperity. May this new year usher in good times, happiness and abundance in your lives. Kind regards, vkn CMD, PS: Pictured are the 'Vishukkani' gifts we received from our several old and new aquaponics farming adapters. Our special thanks to Mr. Rajesh of Circle of Life Aquaponics, Babaji Vidhyashram, Chennai, Tamilnadu; Mr. Sivadas of Shivani Aquaponics, Palakkad, Kerala; Mr. Sidhan of Aswathy Aquaponics, Thrissur, Kerala. PS2: I might update the above list as we expect some more gift parcels hopefully on this Monday.
  8. Hi vkn Nice capture, the seedling looks so strong and yet vulnerable at the same time cheers
  9. It all starts with a seed..After you've dropped a seed in its place directly at the aquaponics sand culture ridges, you can go back and do other things. No more seed care needed. No moistening of the newly planted seeds with misters or watering cans. No fertigation efforts. It germinates and the cycle of life begins. @ CSAF #1 demonstration cum commercial facility, near Oachira, Alappuzha.

  11. Congrats Bryan, Good luck, Cheers.
  12. Hi BM76 Well done thanks for posting , and good luck ahead cheers
  13. Well, Western Dakota Tech's aquaponics system will be making it to the finals in the National Science Foundation's Community College Innovation Challenge this summer in Washington DC!! Aquaponics will be on the Big Stage in front of members of Congress, key congressional staff, and leaders of the STEM initiative. :
  14. SuperStewie, If you want my recommendation for a small demonstration system, I'd suggest that you consider the Integrated Aqua-Vegetable System (iAVs)...for the following reasons: The design embodies the most cost-effective mechanical and biological filtration to be found in any of the aquaponics variants...very useful for a system that is going to be of compact size. iAVs will grow the widest variety of crops of all aquaponics variants. iAVs is the most productive, resilient and sustainable of all of the aquaponics variants. You can read more about the iAVs method on Gary
  15. Good move, VKN. I've long advocated a broader approach to integrated food production through Microponics...and, more recently, waste transformation farming. It's a logical extension in a place like India. Are you obliged, as part of the conditions of the government grants that you received, to produce reports that will become publicly available?
  16. I would assume anything on the web can be more easily hacked? That's how Russian hackers got into power plants etc here in the U.S.
  17. Papaya in aquaponics sand culture.. Here is an update picture of the hybrid red lady papaya commercial yield trial going on at Nanniode.. It is about 6 weeks old. Some have begun to show the first flower buds. Growth is seen rapid when compared to the ones started at the same time in soil and external container culture. More on this later.
  18. Thanks mate, Appreciate you doing that for me. Why Not a web based generator? Cheers.
  19. Wife says: 1. Don't use one that is only web based. 2. Buy a program that you download and keep on your computer. 3. Wife really likes one called 1Password that's available for Mac, Apple, and phones.
  20. It is a bit awkward. The stove comes with a long handled ash scoop, in fact mine came with 3 of them:) They were wrapped together and I assume the employee doing the packing did not notice?? So picture a metal dust pan welded to the shaft of a metal golf club. It works and there is not that much ash. In the aprox 30 days I burned it I believe I cleaned it out 3 - 4 times, took a couple minutes each time. I might have got a 5 gallon bucket of ash total from all the clean outs, wasn't much. Not like a normal wood stove where you are burning a lot of volume of wood. Each fill is like 3-4 pieces of 5" wide 5" thick and 15" long pieces of wood so low volume so low ash.
  21. Is ash clean out any trouble? Really impressive setup.
  22. I wish I could help but I'm nowhere near an expert in this bigdaddy. I'll ask the wife and her colleague at school as they know a lot about this kind of thing.
  23. Hi everyone, Some advise from those who know please. At the moment there seems to be a push or strong encouragement for people to install password generators to protect against hackers...I have a couple of questions... Is tis secure? The reason I ask is you need to provide an email address and password to develope an account...To me a hacker just has to crack your password and they have access to all of your stored passwords in one area... If this is advised, which are the best programmes to install? Cheers.
  24. Hi Cecil, I don't know how it was statistically but I live down in South Australia which typically has a mediterranean climate...I reckon this year we did have a couple of hot ones...40C ish 104F and maybe a bit dry overall in comparison to other years but I didn't think it turned out particularly hot. I do remember saying we had a bit more rain than normal. Summer may have started out that way but finished a bit dry... Right now, we are and have been experiencing glorious weather Max 20C-30C 68F-86F during the days but could do with some rain. (At night please:) ) I wonder how others winters and summers faired? Cheers.
  25. I have tilapia in my basement tank that I never heat in the winter anymore. It's cool enough down there I have to wear a sweater when I work in the taxidermy shop. Unfortunately my temp gauge is no longer accurate, but the water definitely feels cool to the touch. I'm guesstimating lower 60's F. Fish feed well once a day.
  26. Early, I apologize for invading your thread but Andre wanted some pics of the setup. The heater inside the tote. The surround I mentioned, before the gap was filled with perlite. Btw i filled it with loose perlite, not perlite cement. From memory I think it took 16 cf. Looking down in the burn chamber. The air enters between the side wall and that metal plate and the plate extends to about an inch from the bottom so air is forced under the fire, though there is no bottom grate.
  27. Ande. I will post them for you, I had a thread on it on my fig forum so already have the pics.
  28. Had posted this today in greenhouses but saw your post and thought it might help.....if cross posting is not allowed just delete. his may not work for you but........ I have two greenhouses, a 24'x50' A frame about 15' tall at the peak and a 20'x30 arched. The larger GH holds 28 IBC totes with tilapia, 14 totes down each side plus two more IBC totes that each contain home made RDF filters (that are AWESOME) down the middle of the GH are 6 600 gallon lined tanks. I use the water in the tanks to not only raise tilapia but also to heat the GH. I own a fig nursery and start about 2000 fig plant cuttings a year for spring sales and they like to root with bottom heat and they sit on shelves over 3/4 of the top of each tote. Last winter I relied on 1000' of 1/2" black tubing strung back and forth along the rafters of the GH in 4 runs and pumped water through those lines and back to the main sump. This system worked but given the volume of water I could only gain 4-5 degrees per day if it was nice and sunny and on a very cold night (28 F) I would lose 6 degrees. Being in central FL it worked out as we dont get a LOT of cold generally. Front comes and the tanks drop 10-15 degrees over the course of a few nights then weather gets warm and using thge solar could bring it back up. Even still if a front came through and stayed cold and especially cold and cloudy it saw a constant loss of temp over several days and lowest the water got to was 50 but last year was a pretty mild winter. I knew that if we had an exceptionally cold winter that we get perhaps once a decade it could be a real problem and would have a LOT of dead fish and a too cold GH, was just a matter of time. Did a lot of reading and finally I settled on a plan. My first thought was a wood fired boiler but they use a LOT of wood and are smokey and while I am not in the city i'm also not rural either so I crossed that one off. What I did was buy a wood fired hot tub heater, think some call them cowboy heaters? The one I purchased from a company in Canada is called a Timberline volcano. It is small, 38"H x 27"L x 11.5" wide made from SS and the body is aluminum. Even that small the manufacturer stated it was 100,000 BTU but I was dubious about that claim to say the least. The entire heater sits underwater except for the feed shoot that sits 6" or so above the water line and the fill lid acts as the draft control. I did not want it inside the GH so it was situated about 40' away outside the GH and inside an IBC tote. I placed the tote so it was the same height as the tanks in the GH. Added a second small 1/2 hp dedicated pump and ran a 1" line from one of the IBC totes that holds one of my two homemade RDF filters. Because the hot water return pipe would flow back to the GH by simply gravity that line was 2". I knew the ground would chill the water stealing some of the heat in the buried hot water return pipe so I ran 4" non perforated drain line and cut a slit the length of it. The 2" line was placed inside the 4" line and then made batches with the cement mixer and filled the pipe with a combination of 1 part portland cement, 1 part sand and 6 parts perlite to make lightweight insulating cement. I wedged the 4" pipe open so i could fill it and when the 4" line was 80% full I laid the 1" supply line from the new pump on top of the 4" line and poured more cement over all of it to a depth of about 2" above the 1" line. The IBC Tote that is 40' away and holds the heater I was a bit concerned about it losing heat to the atmosphere especially on a windy day and our cold normally comes with a lot of wind. My solution was to bury 4 4"x4" PT posts 6" out from each of the corners and built an enclosure around the IBC tote using recycled black plastic twinwall GH material. In the 6" gap between the twinwall andtote I poured more perlite completely filling that airspace up to about an inch from the top of the tote insulating it. I added another piece of twinwall to the top and the 6' tall 6" wide smokestack comes out through it. The 1" line was run into the tote about 1/2 way down the tote and the 2" heated water line is through the tote 1/2 way down also then elbowed and runs up and pulls the hot water from just 1/2" under the surface. To say it worked is a collossal understatement. I was BLOWN away. On a cold day I would light the heater and in 45 minutes the water at the surface was already 120+ if you stick your arm down in the water the water just a foot deep was still cold. You can touch the outside of the heater underwater while the fire roars inside and it was just warm to the touch, maybe 85 degrees or so? My setup which is roughly 12,000 gallons of water the heater would raise the water temp in the system 1.5 to 2 degrees per hour. The heater being small uses up very little wood and once burning well is 100% smokeless. I never even bothered to use the 1000' of 1/2" solar lines at all during the winter. I would let the heater run 6 or so hours and refill it about once an hour but each fill is only 4 pieces of small firewood. Once the heater is running(and pump on) temp in to the sump would settle at about 85 degrees and the 1/2 HP Goulds pump pushes a LOT of volume. It was a dang good idea I put it in as this winter was our coldest in over a decade. Without that heater the fish would have been dead as we had front after front move through in a 30 day span of time. With the heater my water never dropped below 65 and I ran the heater total maybe 30 days. Also and this was simply an the late afternoon I would fill the unit with wood and close the lid/damper completely. I did it so I would have a nice bed of coals in the morning and would not have to relight it, even though lighting the thing is so easy and fast. One morning before I had added any wood and the pump was off and had been off since the previous afternoon I was in the GH and happened to walk by the sump and noticed the temperature gauge on the outflow water and it was at 80 degrees. I looked at the temp gauge in one of the tanks and it was 70 degrees. Thinking the other digital gauge was broken I pulled it out and put the sensor in the fish tank where it dropped to also 70 degrees so it was working. Popped it back into the outflow pipe and put my hand down in to the sump water and sure enough 80 degree water was flowing out of the pipe even with the pump not running. Came back in the house and googled and found the answer I had made an inadvertent thermal siphon.....had no clue such a thing even existed. So even without the pump running cold water still goes to the tote and warm water still flows back to the sump. I plan to drain the heater tote of the fish water and add piping to plumb it in to my inground pool to also heat that, just need to see if chlorine will harm the aluminum before I do it. I have no affiliation with Timberline at all and I know other companies sell similar heaters. If I had had the time I would have probably welded one myself but my aluminum fabrication is generally not pretty, to say the least. Also was worried I might not be able to get it 100% waterproof.
