I always hated wrapping the corners on Christmas presents 😂😂😂. Looks great man
"folding in the corners is really a horrible part of the project...it's not like wrapping a present" lol love the honesty. Nice work! You've inspired me to build my grow bed out of steel and weather proof particle board. Thanks :)
it will be exciting to see the greenhouse when it is in full production. thanks
*stern voice* It will be exciting to see when you're going to finally upload some content, Jeb!
We're hungry for some dramatic gardening :)
I was thinking about doing a parody video like Jeb's format. ;-)
you are master of your trade from CAD designing TO building each of the the plants. i
enjoy watching your presentations and learn a lot . thank you very much !
Thank you for showing us for continued ingenuity and production. I find this platform of sharing knowledge and collaboration has allowed for the spread of individuals getting into gardening and hydroponics as a whole.
Great work! I can't wait to see what it looks like next summer when it's full of life. Everything you do is so thoughtful and well done.
I really enjoy your videos, planning to have a system like this one day. Until then, I will watch and learn as much as I can . Thank you for showing me how it is done.
Looks great! Love the progress.
You know it's all very well being told how to do things or being shown plans but I've always been a visual learner so this series of videos are invaluable to me than you for taking us along with you and I wish you every success in what you do .p.s. Subbed
Rob, I found a product called Blue Max, its a paintable water based non toxic rubber. Iv'e found it to be pretty handy stuff. It can't take UV light over years, but water helps with that. In all the things you do it might have an application somewhere.
joy joy! I love this series.
Grinder and paint make me the welder i aint!
Great video. Timelapses would be great for the rest.
Maybe come spring ill send you a few more voodoo lilly corms to try. I have a few flowering this year which is neat since its only the second time ive had them flower.
There's no doubt that I'm not a good welder...but they seem to hold together!
Please when can we see the remaining parts of the video? I will like to see the green house in full production. Great effort and welldone
putting the liner, I just filled mine with water makes the liner sit nice.
Thank you
Good job Rob. Looks like it should last and do the job well. Except I hate Bell siphons ;) My research project in nitrification is this year. Keep up the good work!
Another thing you could add is Underground Earth temp heating and cooling system using the constant underground temperature to cool in the summer and heat in the winter
Where do you buy the expanded shale?
What type of heat will you use in the greenhouse?
Thank you for this series I have learned a lot.
I am watching the entire series... how much for the pond liner and what is the length and with of the role?
You could use pvc pipe as clamps for the liner. less work and easier to fix later.
I wonder if I can use that same lining for a above ground fish tank instead of using acrylic
Put a really good sunblock on your arms. And it will reduce the sunburn. By the way, great job. It looks really great.
Could you make the same thing with the raft-master conduit?
Is that net used to cover the greenhouse waterproof? and can you tell me the thickness of the net?
I enjoy your videos. Were do you get the large amount of expanded shale?
I buy an 18-wheeler at a time and resell it. ;-)
Hi sir, do you use media bed as biofilters?
and if we use the media bed as biofilters is there a need to have the dwc bed in the same system?
What do you recommend for large commercial based aquaponic system : media beds or moving bio filter?
Also since the media beds take some time fill and then drain off, does this create a time when the deep water bed are not fed with water
Usually MBBR is used, but it depends on what people are trying to grow
"Grinder and paint make me the welder I ain't"
Thx...شكرا....chukrrrra
Did you have heavy snow? Did you clean the tunnel or did the design take care of it?
It slides off on it's own. I just have to remove it from the base if it gets too heavy.
Kkkkk "Black pipe" was the best.... 😊 ,,, (By the way, exelent job)
Where can I get the bulkhead fittings? Online?
I'd love to know this too please. I have purchased 1/2" bulkheads at Home Depot near the toilet repair parts, but there was only one type and one size, so I'd love to know where to get different options.
So what is alot of electricity? 40Watt? That would about 300gal/hr
What kind of liner is this
Try a heat gun for the rigid corners of the plastic.
what flooring?
I would have centered that auto siphon. I have made several large beds and if the siphon is to one end the bed will never drain 100%. The water will be high on the opposite side especially once roots start to take hold.
It should be on the opposite side so you have a complete exchange of water and it will minimize the change of any anaerobic zones. If by some change the roots were that thick the bed would just flood over and drain through the overflow.
I have two 500 gallon fish tanks similar to you and just finished a fishless cycle toady with the first fish. I added 50 Tilapia and it's so exciting. I copied your spray bar design and I quite like the results. However, it gets the volume of the tank water spinning pretty good. I am not sure if this is a good thing for the fish or if I should provide some structure to give the fish an escape from the constant spinning current.
you probably don't want the water spinning too fast, just enough to keep things moving a bit. Even if some of the debris along the bottom isn't moving, as the fish swim by it or hit it, it will slow work it's way towards the center.
@@Bigelowbrook Thank's for the advice. I have taken it and slowed down the merry-go-round. Now I am getting into a ph issue. It keeps gradually climbing up to 8.7 now. I suspect my river rock media (even though I tested it first) or possibly my concrete DWC. The DWC is lined with a concrete waterproofing substance but this may be inadequate. I have been trying lime juice while I wait for phosphoric acid and a GH/KH test kit to arrive. My hope is that I can get it down with acid and the increased vegetation will maintain it at a lower level as the system grows. This may be a vain salvage attempt and I need to install either a plastic liner in the DWC and/or spring for Hydroton.
@@9squares citric acids will kill your bacteria and shouldn't be used. If you have to add acid, use muratic acid (diluted). It will be a futile attempt unless you know what the cause of the high pH is. It's probably your media.
@@Bigelowbrook Thanks for the heads up on citric acid. I am hearing both sides on that one, many say it will harm your bacteria and others say "hog wash" they have been doing it for years. I am in very rural Thailand and it's all I have available for a few days. I thought I would experiment with small amounts and see what happens. Interesting that you suspect the media over the DWC. I was afraid of that. I have looked high and low for expanded shale but short of importing, I can't find it. Expanded clay pellets are available but they are quite dear.
how has the Solar wrap be working out
I like it! no problems so far
@@Bigelowbrook Thanks for the reply
There's a bad background hum, is that a pump or a buzzy microphone?
air pump. I forgot to turn it off.
What do you heat with
I don't grow during the winter.
Actually marine grade plywood is more durable and last longer if it gets wet but chip wood is cheaper and is pretty durable as long as it’s out of waters way
this isn't the standard woodchip board.
what is the life of that white liner?
hopefully it will outlast me.
Below can rear fishes isnt it.
I wonder how much the materials for this cost?
Well played, Google. Well played.
I don't like using gravel because all of my friends that have used gravel in her aquaponics always had problems with ph they could never get it to stabilize between 6.5 and 6.8 it always would stabilize at 7.2 and then they would have to add stuff to adjust it and then it would do the same thing again this happened with a couple of different friends of mine until I got them to swap out their gravel with the fired Hydro clay balls or volcanic rock basically neutral media that has no chance of leaching anything out to affect the pH also when I was talking about the air injection I'm talking about something different than an AirStone I found the air stones where are clogged up and eventually have to be replaced I will send you a link of a video when I'm finished with the air injection I'm talking about
They're using gravel which probably has limestone in it. I use expanded shale which is pH neutral.
@@Bigelowbrook Where do you buy the expanded shale?
What type of heat will you use in the greenhouse?
Thank you for this serious I have learned a lot.
if any rocks get kicked in or thrown in by visiting children ;)
