Hydroponics Advice

I'm interested in starting up a little NFT hydroponics system. I just want to grow some stuff like lettuce and cucumbers, etc. Living in Florida, is my timing really bad (is now a bad time to start)? Also, with hydroponics and veggies, after a harvest, do I need to replant, or will the plants simply continue to grow? (I'm new to plants, if you can't tell) Also - where can I find supplies like an inexpensive pump, expanded clay balls, and nutrients? Any other advice that you think I might need would be greatly appreciated, thanks!

What is the best manufactured hydroponic system for amaeturs?

I'm interested in trying hydroponics to grow some tomatoes and peppers but no absolutely nothing about it. I'd like to start out with a manufactured system first to see if it's something I really want to pursue. I've spent hours trying to figure out who has the best system for a reasonable price. Any suggestions? Thanks.

Plants slowly dying in an odd way, any gardeners out there who can tell me why? Answered

I have an aerogarden with some strawberries.  They started just fine but they recently ran into some trouble.  The leaves started yellowing.  I did a little research and it seemed to match the symptoms for magnesium deficiency.  I switched nutrient mixes, thinking that might help, but it seems like it isn't getting any worse or better.  It's looked like this for about a month, not much growth, not much die off.

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

off-grid solar/wind powered greenhouse

 Hello DIYers, I am planning on building a simple greenhouse (hoop-house) this spring. The construction will be for an 8'x12'x8'H design. Building this part is wonderfully easy. The hard part is building the off-grid power to supply power to the greenhouse fans and hydroponic pump(s). I'm not sure where to start with the plans.  Here is what I am needing some guidance: Do I build a PV panel then design my electrical needs around that...or vice-versa?? (I have forty 2W solar cells on order) I know i will need batteries...how many 12V batteries do I need? Type? What is the best configuration for the batteries? Should I use a DC hydro pump or AC hydro pump? DC or AC fan for cooling? Future plans include using an arduino to be the main controller.... Please keep in mind that this is a small(ish) hobby greenhouse and I hope to build it to be fully off-grid, at least for the summer months. I have the time to build it, but don't have the know-how for fully designing it (electrical stuff confuses and scares the crap outta me). I'm not against keeping the price low, but am willing to spend a few extra bucks to make sure it's designed right.

Reporting plagarism: Arduino Hydroponics

Hello, It has recently come to my attention that an instructable here was blatently plagiarized from one of my previous projects, and in fact actually won an award. 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

Shameless self promotion

I'm not sure why I waited so long to post about this but something pretty cool happened to me because of my last contest entry. I entered mySolar Thermally Pumped Hydroponic System in the "keep the bottle" contest. For some reason I didn't win ;-), however, shortly after the contest I received a PM. The PM was from the Harvard Graduate School of Design, they were putting on a conference on Ecological Urbanism and they wanted my project to go on display for six weeks. I, of course, was honored and after negotiating an enormous fee (j/k) I shipped the project up to them.Recently while looking for some more info on the subject I stumbled across their Flickr Pool and two photos of my project. I have to say, it's almost fantastic that a project, composed primarily of empty soda bottles could go from my backyard to the halls of Harvard.And, obviously, this would never have happened if Instructables didn't exist, so my heartfelt appreciation to Eric and the fine people behind the scenes of the website. So without further ado, the pictures.

Water Recycling with a Hydroponic Bog Garden

Clean water - we all need it.  Treating and reusing sewage and other waste water means reducing the burden on the already limited supply of water from our lakes, rivers, and underground aquifers. Instructables user Biotank posted this excellent Hydroponic bog garden. It's the final step in a series of sewage water treatments, and uses bacteria to clean the water even further so it can be used for irrigation.  This system can be combined with a garden for water-loving plants as shown here, or with a fish pond.  While this bog garden isn't likely to fit in your backyard, it's a great example of thinking outside the box to solve the problem of water reuse!  Check it out, and get inspired. What are you doing to conserve or reuse water?  What would you like to do? This post has been sponsored by Pepsi. The Pepsi Refresh Project celebrates the people, businesses, and non-profits with ideas that will have a positive effect on our world.

I want to set up a hydroponics system but don't want to buy commercial nutrient or medium. Answered

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.

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.

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

Can I grow tomatoes (and other vegetables) in part shade (4-5 hours)?

I've recently moved into a new house (I'm not telling you where) and the backyard only receives 4-5 hours of sunshine per day. I'm wondering if my vegetables requiring full sun will still grow? I'm tired of seeing the same old "it must have at least 6-8 hours of sunlight each day" . If this is still not possible then I will consider a hydroponic system with growth lights under my stairs... I was always interested in hydroponics ever since I saw an advertisement for the AeroGarden, but I never actually tried to build a system and I definitely can't afford one.

Aeroponics

I hope my mom doesn't see this, its going to be her birthday gift hopefully ;D. I was looking around instructables for good projects for my garden-loving and food-growing mom, and noticed several hydroponic systems. They all looked nice, but I noticed one thing: they all used the nutrient-film or submerged plant technique. I'm no expert, but this seemed bad for the roots. Rot, anyone? I recalled a system I had seen at Walt Disney World in the distant past (OK, 4 years ago :P), where plants roots passed through a nutrient-laden mist. This seemed a better solution to me, allowing the best nature of hydroponics to take root (no pun intended lol): supplying the roots with nutrients while allowing them to breathe and supporting them. I thought about how to create the mist and it hit me: a hose sprayer. Most sprayers nowadays come with an adjuster nozzle to change the flow, so if one were to move it to "mist" position, tape down the handle and attach it to a large submersible pump on a timer, you have a cheap aeroponics system. I'll be writing an instructable when I can, so stay tuned for updates.
