Sawdust as a medium for hydroponics? Answered

Actually I have 2 questions pertaining to hydroponics. First you should know that I have a passive hydroponic system functioning right now the container is partially submerged in a nutrient solution with holes in the bottom of the container. The medium I'm using right now is perlite to allow more oxygen and act like a wick. I do have a top layer of aquarium gravel to anchor the plant better. I've been thinking of trying to add more oxygen to the roots by using an air pump. I was going to insert the tube from the top (the dry section above the water) pointing down to the wet section to blow some air to the roots. Would this be an unnecessary addition if I continue to use perlite as a medium? My second question is the title, would sawdust work as a medium for hydroponics? I assume it would be able to act like a wick for a passive system my concern is would the roots get enough oxygen in sawdust? Also most mediums are inert sawdust wouldn't be, would that have a negative impact on my plant?

automated hydroponic system ?

Hello, I want to make automated hydroponic grown plant system that will sense condition and provide sufficient Mineral Nutrients for growing hydroponic plant.  we place the seed into water, seed grow into water , growth should start after 2 or 3 weeks.we don’t feed fertilizer until the first set of true leaves appears When seeding develop their true leaves and roots. Its time to feeding fertilize.we need to provide right fertilizer for good growth Most common fertilizer is NPK, after two or three weak or after the first set of true leaves appear we need to fertilize plant. Fertilize approx every two weeks Automated system (small and low cost system) Parameter – conductivity Project part list Electrodes probes Micorcontroller Amplifier or filter Resistor A to D converter Ic Volve or relay Automated system that Add more or less fertilizer into water ,that maintain conductivity range Best time to fertilize plant Time- fertilize plant after their active growth ,after two or three weak or after the first set of true leaves apper we need to fertilize plant ADD small value of NPK into water because small plant take less fertilizer After two weeks Add large value of NPK into water because large plant take large fertilizer Provide enough NPK to complete their life cycle we can measure conductivity of whole solution. how to make Automated system that will Add more or less fertilizer into water on basis of conductivity If plant need more or less fertilizer system  will adjust itself

>_< Specifications... i needz them.

So... about six months ago i moved into  new place.  it's great, but the previous tenants kinda trashed the place.  they left loads of rubbish around and were generally horrible to the house.  The previous tenants did leave a few things that are kinda nifty.  First, they left tons of PVC pipe. i have something like 20 ft of 2 inch pvc pipe, 15 ft of 3/4 inch pvc, and 10 or so feet of 1.25 inch pipe.  the second thing they left was an above ground water filter.  The owner's manual to the pump can be found here online:  http://www.pooltoysource.com/images/pdf/RVR005.pdf This got me to thinking i could setup a little hydroponic rig in my house. I have a hallway window which i'm too cheap to buy a blind for, and letting a bunch of plants cover it over appeals to me.  However, there's some problems.  The owners guide is critically lacking in any sort of technical specifications and all the info on the web just relates back to the pool pump being used as such.  Sooo... if anybody knows anything about what kind of performance can be expected out of this little dandy, let me know.

The instructable in question is: https://www.instructables.com/id/Hyduino-Automated-Hydroponics-with-an-Arduino/ Proof that it ripped off my project can be found here; my original forum post here goes back to 2012, the instructable in question here was posted November 2014: http://forum.arduino.cc/index.php?topic=130344.180  My repository containing my code on github: https://github.com/BillieBricks/Billie-s-Hydroponic-Controller/blob/master/HydroponicControllerV1.1.0 The code from the instructable in question: https://www.instructables.com/files/orig/FSR/83MH/I2G1F678/FSR83MHI2G1F678.ino The code is mine, line for line, with the exception that the plagiarizing author in question removed my comment at the top with my name as the author. I tried to contact the author, but my messages went ignored and the comments on his instructable page were flagged and deleted.  The author in his instructable says "Big thanks to BillieBricks for working out a lot of the code," but in fact the entirety of the code is simply ripped straight off from my project, along with the ideas and implimentation. My desired outcome would be to either see this instructable removed, or to have the author include that the entire project be credited to me, rather than stealing credit for something they didn't do.  Thank you, Billie

Help me with my hydroponics problem. Please!

The directions were great. Except, now that I got my air pump going and everything else, there is a smell coming from it. It smells like garbage. Also, when the bubbles come up to the surface there's a bunch of bubbles left at the surface...it looks like a bubble bath. The first time this happen with the smell I just got another air stone. So, now I have two in the container. I emptied the old water and solution, cleaned the container and add more water with fertilizer. This worked great, but then two weeks later it was time for me to put fresh water again and now it's doing the same thing with the garbage smell. Please give me some ideas on how to get rid of this.

Advice needed on nearly complete instructable

Sorry this is a bit long, but there is an actual question at the end, honest! Every morning at work I walk past a table at the end of our mailboxes that people put give away items on. Its usually a catalog of some form but for a long time now there's been a stack of empty CD spindles and a sign beside them that reads "free to good home." I could have taken them and sorted the mountain of CDs in my office or used them for small parts bins, but to make it areally Good use of empty CD spindles I had to ask myself "IS there an instructable in this?" There are some good ideas for using CDs and a few for the spindles, but at the moment what interests me is hydroponics. So using CD spindles or more exactly the plastic covers they come with I built the basic part of this excellent instructable: http://alturl.com/oa2qt    and I learned a lot of stuff about water pressure and such and once I had built the 2liter bottle method described above I decided to try sealing one of the CD cases and use it for the water container at the bottom of the stack. That took about 4 sticks of hot glue and a couple of burnt knuckles to get a good seal. Turns out there's holes in the center spindle too but I didn't notice them till I had hot glued the container closed. Also ignore the bit of blue air hose inside the container, I was up way too late and flipped the CD spindle 'right side up' which caused me to attach the air hose to the wrong outlet and basically made it useless. I thought I'd need a lot more water in the system than I do so I chose to use a 100ct CD spindle instead of the 50 ct spindles you see on top. (Thanks to all for the ideas on how I could have done it easier!) So far this part of the project was just overlaying the ideas in the excellent instructable above onto the materials at hand. So what I ended up with is an air pump from a fish tank pumping air into the bottom chamber. (the clear hose in center of picture.) This builds up enough pressure to push water thru the blue hose and up to the top CD spindle. I've cut holes the diameter of the air hose into the base of the spindle and this lets water slowly trickle into the Perlite growth medium. When the water reaches the bottom it goes out similar holes in the clear plastic CD cover and starts to pool up a bit to start the process all over again. There is just enough lip on the lid and the bottom of the next spindle to keep it from spilling down the side before this happens. It helps to use the same brand CD spindle all the way up. The clever part of this instructable is that each CD spindle easily stacks in place and you can remove it or change the order without having to dig up or harm the other plants. The base is very stable with several ounces of water in it and I'd imagine you could put 4 of these in a stack and happily swap plants in and out all summer long. The height of the stack depends on how strong your air pump is. I tested two different ones and both were capable of lifting water over 4 feet  up the air hose. Caveat: I haven't actually grown any plants in this yet, so your mileage may vary. Using the stack of CDs for use as apartment planters or sprouting medium would have satisfied the original curiosity for what to do with all those left over CD cases, but in absence of glowing blue LEDs or CO2 lasers I thought Hydroponics would be a great way to sex up the overall idea. I imagine you could use spanish moss or bedding in place of the Perlite, or even soil if you used a coffee filter to cover the holes till you were ready to stick a seedling thru it. This Instructable isn't quite finished as presented. There's a small problem. As you can see in the photo there's a half height (25ct) CD spindle between the water container and the stack of planting modules. Remember that hole I mentioned in the end of the CD spindle? I closed that with a bit of plastic and hot glue, but it made me wonder, COULD I put some sort of check valve here to allow unused water to trickle back into the holding tank YET not lose the hard fought air pressure that's pushing the water to the top of the column in the first place? Since I'm re-using all this old aquarium tech I thought I'd try one of those tiny check valves that keep water from backwashing into the air pump when its off. I'm not sure if it will work in this application or even how much air pressure it will tolerate. This will require some disassembly of the CD hydroponics tower and I thought I'd ask here for suggestions before heating up the glue gun again. So what do you guys think? This has been a lot of fun to think about and I can't wait to bring the media guy  around into my office to see how I've re-purposed the spindles. Just this one last step away…. cheers, flashj

DIY LED Growlights from LED Xmas bulb strings

I just got an Aerogarden for Xmas and it is a pretty neat little unit, but it has some annoying and expensive problems. The biggest one is that it uses CF bulbs that are on 16 hours a day, and they say that you need to replace the bulbs every 6 months, because the spectrum of the bulbs change as they age, making the plants grow less well. I did some research and found that the Weed industry has created a solution: LED arrays with a combination of red and blue LEDs (the color frequencies plants thrive on). These arrays are very long lived and use less than 1/2 the power of the CF bulbs in the Aerogarden. The problem is that even the cheap ones (200 LEDs) are $50, and you would need 2 for complete coverage in the Aerogarden. Then I had a brainstorm! LED Xmas Lights. They are already wired, ready to mount on a panel, and you can get Red and Blue strings of 100 on ebay for about $10 incl shipping. I don't know if they are the right Red and Blue, but it is an interesting experiment. Even if it does not work, you are set for Xmas lights for next year.

Is the effluent produced by a biogas generator enough to feed plants in a hydroponic system?

I'm looking at various ways to grow food free/almost free in a small space.  I would like to grow enough veg to feed myself comfortably. Hydroponics in a vertical farm set up would allow me to grow lots of veg in a small space, trouble is I now need nutrients to feed my plants. After much reading, it looks like I could anaerobically digest all my food waste (including meat, diary, plant stems and anything else that decomposes) in a biogenerator. If I use the resulting liquid effluent, would this alone be sufficient to grow healthy plants.  Are all the nutrients they need going to be in sufficient proportion and are they all in an accessible form for plants. Will I need to add bottled nutrients from a store to top it up? Another question is if the effluent is safe or a biohazard?  My reading so far suggests that most pathogens are killed off in the anaerobic process. Is there anyone who has tried anything like this already? So far I can only find people who are fertilising crops in soil with the effluent. Any comments are greatly appreciated. P.S: for those who do not know what a biogenrator does/is.. a quick description.  Its a sealed tank filled with water, waste (shredded) is added, naturally occuring bacteria in the water (not dependent on oxygen to survive) breakdown the waste into their nutrient parts, methane is also produced by the bacteria (methane is CH4, carbon is in the waste and hydrogen is in the water), the methane can be tapped off for burning and the old liquid can also be tapped off, supposedly this liquid is an extremely good nutrient source, though I don't know if it could sustain plants grown hydroponically on its own.

PVC vs Hydroponics and Rain water collection - a timely warning

Hello one and all- I've been interested in hydroponics for a very long time.  Now the time has come around that I should get out and get some form of it built and begin using it.  I began researching different styles and of course reading here on Instructables. I read about all the different styles and methods.  I looked at kits, partial kits, and building my own design.  I also began to think about moving away from the use of the well on my property.  I looked into rain water capture.  Here in the north east there's been no shortage of rain even in a "dry" year. In nearly every tutorial or kit I've found them based on a PVC product or using PVC materials.  I remembered that there had been an issue with Lead (Pb) being in PVC. I looked it up.  It appears that there are serious issues with the use of PVC and Lead is only one of them. Here is a sampling of the links to the issue of Lead in PVC - http://lists.essential.org/1996/dioxin-l/msg00205.html http://healthychild.org/blog/comments/safe_pipes_mean_safe_water/ http://www.sciencedaily.com/releases/2008/06/080602091241.htm http://archive.greenpeace.org/toxics/reports/whatswrong.pdf This is just a few links - there are a ton more. It's an interesting read and should give everyone working with PVC cause for pause.   For example instead of using the PVC gutters I had planned on for the rainwater collection I've been thinking about making them from wood (Plywood) and coating the inside with Food Grade Shellac.  I will be using PVC pots for container vegetable gardening this year but I will rough up the interior of the container (taking precautions - respirator, gloves etc) and again using Food Grade Shellac to prevent the PVC coming into contact with the growth media or growing vegetables. I was sort of surprised by this info and just thought I should share it just in case someone was unaware of the issue.  I would like to cross post this but am not likely to do so for concern of running afoul of some rule.  Feel free to share this info though.  In fact please share this widely- Good luck with your projects, Marcintosh

Need help with Aeroponics misting system any ideas? Answered

I've been struggling to build an aeroponics system and the only problem I have right now is the misting system. I purchased some misting nozzles off amazon that I inserted into some vinyl tubing and sealed with a silicon sealant. I used a small DC 6V pump powered by my Arduino to pump the water to the nozzles. Now the little pump couldn't provide enough pressure to create a mist of water (I think its pump rate was something like 15GPH) it came out with some of the water leaking while a steady stream sprayed in four directions. So my question to the instructables community is was it my little pumps fault or did I get ripped off buying bad nozzles? What pump should I buy that will pump enough pressure to create a mist? here are the nozzles I bought and here's the pump I bought: http://www.amazon.com/gp/product/B004HHW0FU/ref=oh_details_o01_s00_i00    <-- the pump http://www.amazon.com/gp/product/B004U3MRIG/ref=oh_details_o02_s00_i00     <-- the nozzles One more thing, I was thinking of a misting system which I'm unsure will work. I got the idea driving behind a truck after the rain when the road was wet. The wheels were spraying a mist behind them as they drove over the wet road. Could I simulate that effect at all with an electric motor and a small wheel?

Can i just flood the soil the plant is growing in for a temporary portion of the day? I don't have a problem with the pump, just buying the nutrient / medium. Can i just use soil and wet it down really well once a day and then drain it (out the bottom)? Would floating soil in the water being circulated through the system work? I could empty water / put more soil in on a regular basis.

What LEDS do I need to make a "Grow Light" for growing plants and vegetables indoors? 110V & 12V. Thanks! Answered

Indoor Grow Light for plants and hydroponic gardening.  I need both 110Volt and 12 Volt schematics for out off grid home. My LED knowledge is very limited so I need the specs on the LEDS.
