Understanding MAMA v3′s plumbing

2:53 pm in questions, Version 3.0 Modular Airlift Columns by James Moon

We built a starter window farm earlier this year, and now I’d like to build a bigger one to cover the entire window. (I actually have a really huge window.)

But I’m having trouble understanding the assembly instructions for plumbing, specifically at and after bottle cap assembly (methods A, B, and C).  At the end of the instructions for each method, it ends with putting the other end of the airline tube into the pump.

I must have missed something or am not understanding how this works, but if you have four or more columns, how do they share one pump? In the full assembly picture, it looks like each doesn’t plug into the pump but rather into something with a loop above it. I can’t seem to find mention of this in the instructions.

Can someone please enlighten me?

Hi all,

I just completed my first window farm and wanted to share my experience.  Just as I decided to get one of these together, I had an assignment to create a video about the environmental subject of my choice, and this seemed to fit perfectly. Here’s what I came up with: http://www.youtube.com/watch?v=2fif-hNj47M.  I used several images from this site, so if I used one of yours and you want it removed, then please let me know.

I was particularly impressed with Dave’s Manhattan Window Farm design (http://our.windowfarms.org/2011/01/07/my-manhattan-windowfarm/), and used it as a starting point.  In the interest of simplicity and energy conservation I decided not to use lights or a pump, at least to start.  I don’t live anywhere near a hydroponics supply store, and was unable to find nutrient solution, net cups, clay pellets, or rock wool.  Instead I used Vigoro all purpose soluble plant food diluted for indoor plants, cheap plastic plant containers that I already had and a mixture of vermiculite and pebbles.  I figured that the vermiculite would retain moisture better between manual waterings anyway.  I wanted as large a space for roots as possible, so I used 2L soda bottles, which I regularly use.  I could only find 2″ split ring hangers but they turned out to be just large enough to hold the neck of the bottles and keep them close (but not too close) to the shower curtain rod.

I bought some romaine, arugula, and red leaf lettuce from Lowe’s so I could include actual plants in the video, and for the instant gratification, but in the future I will be using seed, of which I have plenty, to start one with herbs and another one or two with things like beans and peppers.  I waited too long for the first watering and I lost a few leaves because of that and damage sustained during transfer, but otherwise they’re looking good ten days in.  Since, I have been watering with 2-4 cups of solution every 2-3 days.  The red leaf is growing really well, while the romaine seems to be struggling a bit.  The arugula is a little bigger, but has not changed much, although they have all grown.

Here are some pictures:

I would like to thank everyone who has contributed to this project.

I lost one (the smallest) of three of the romaine plants to what looks like root rot but the others seem to be doing well-

and unfortunately the arugula looks like it’s going to seed already

Window Farm 1 Year later….

6:28 pm in Completed Window Farms, made from scratch (without a kit), posts with pitcures!, Version 1.0 Reservoir System by Cambria

I built my window farm in march of 2010. since then, I’ve learned a lot, and I thought I would share my

experience with you guys.

First of all, mine is a 24 plant reservoir system. The air lift system had already been adopted as the superior system by the WF community when I began my WF, but I just wasn’t on board. I didn’t like the gurgling sound, the limited number of plants, the fact that it had to be turned on for so long. I’m not criticizing the air lift system, but it just wasn’t for me. The reservoir system, in my opinion, is beautiful, the number of plants it can support is seemingly endless, the water pump is completely silent, it only runs for two minutes every four hours, and the sound is like a soothing rain.  My system has been tweaked just a bit to fit my preferences, and I’ll describe the details of my system at the end of this post.

Getting Started

So, I started by garden from seed using peat pellets. I’m no gardener by any stretch of the imagination, I don’t know how to prune, harvest, or tinker with nutrients. So I just tried a little bit of everything- lettuce, cucumber, peppers, green beans, cherry tomatoes, okra, spinach, and a few herbs that I didn’t start from seed, but bought planted. I washed the dirt from the roots when the little guys were big enough to transplant into the WF, which seemed like it would be really traumatic, but none died, not one.

Everything was off to a good start, it was looking beautiful. Visions of serving coffee to curious neighbors who stopped by to ask about my awesome garden danced in my head. But the cold hard reality was a lease violation from my apartment complex. They didn’t like my “display” and insisted that I take it down immediately or be evicted. Not to be deterred, I simply lowered my blinds, and opened them facing upwards so they could get light, but people from the ground floor couldn’t see in. This worked fine, and provided trellis for the okra and cherry tomatoes. I moved to a different apartment four months later, one with south facing windows that didn’t mind if I had a WF.

The lighting system was always a concern for me. Something about repeating columns of dripping water and electricity just didn’t sit well with me. I wouldn’t leave the lights on when I wasn’t there, and eventually I just took them down. The garden didn’t seem to mind too much, some of the veggies got a little leggy, but overall, I think it was alright.

Results of the first Crop

Some veggies did better then others,  the cherry tomato plants got HUGE. Like, four feet tall.  If I had known more about gardening, I would have had a better yield. The lettuce did really well, not the spinach. I didn’t get very many veggies, a few cucumbers and okra, maybe one green bean and a couple cherry tomatoes.  I’ll do some more research before planting a bunch of veggies again.  The  Basil and sage, however, were wonderful! they stayed nice and bushy around their respective bottles, perfect.

Second Crop

It was fall and I didn’t have the gardening bug like I do in spring. I wanted something simple and pretty to look at through the winter. So I picked up some rockwool and a package of flower seeds. I think they were marigolds. Just a package that was at the grocery store. I dropped a couple seeds into the rockwool and put those into the WF. Not long after that, I had a wall of pretty flowers to look at during the dreary months of winter. Unfortunately, I didn’t even think to take a picture for you guys.  Sorry.

Third crop

Spring approaches again, and I want an herb garden. It’s been nearly a year, and I need to clean the WF before planting (can we call it planting?) the next crop. The modular nature of the system made it pretty easy. Fresh hydroton, I ran the net cups through the dishwasher, rinsed the bottles, and scrubbed out the reservoirs. The tubes were lined with algae, which I knew better than to buy clear tubing, but it hadn’t clogged the tubes or anything, so it wasn’t a big deal. Pipe cleaners woulda worked, I’m sure, but we used a metal coat hanger and put a bit of cotton on the tip, the tubes were like new.

I really liked the herbs from last spring, so I pick out a bunch of herbs that were already planted in the gardening section of any store at this time of year. Lets see- I got cilantro, dill, sage, thyme, tarragon, basil, mint, and a few peppers for the husband. Each plant was in a disposable pot, and actually had three plants in each pot. I know it seems traumatizing, but it worked for me: I take the plants out of the pot, and gently but firmly shake as much dirt off as possible. Then I ran it under water to get the rest of the dirt off and try to untangle the roots as best as I can. Some of the roots simply will not come untangled, and some roots do get broken. I tried to minimize this, but it’s unavoidable. The plants were just fine, though. Not one died, even though they were probably quite shocked.

And that’s my garden right now.

System

My system is a six column 24 plant system.  The window it’s in now is bigger than my last, so I may add another row on the bottom for a 30 plant system.  My top reservoir is a  four inch diameter, six foot long pvc pipe, with drippers I found from HomeDepot. I keep the top reservoir hidden behind a valence.   Here’s a picture of my drippers. They come with six on this head, but the drippers just pop right off.

At the end of each column, I have a tube which drains the water into a 1 inch pipe, which is angled so the water drains into the bottom reservoir. My bottom reservoir is a plastic box with lid that I picked up at walmart, but I spray painted it to prevent algae from growing in my reservoir. The bottom reservoir holds the water pump, which is for fountains pumping water 8 feet high, I found this pump for 40 bucks at home depot. Something like this: http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&productId=100083846&langId=-1&catalogId=10053&ci_sku=100083846&ci_src=14110944&cm_mmc=shopping-_-googlebase-_-D28X-_-100083846&locStoreNum=589

Beckett 3/64 HP Submersible Fountain Pump

Model # M400HD

Internet # 100083846

I tried finding the hydroponic materials locally, but most places just look at me funny if I ask for hydroponic supplies. Eventually I found hydroton, nutrients, rockwool, and net cups (for .25 each!) at a local head shop. Which is always kinda fun.

My WF did end up costing a lot more than an air lift system, my water pump alone cost $40. but I like it.

A few problems that I ran across: my system drips into a pipe that drains into the bottom reservoir, the tubes fell out a few times. Tape didn’t work, and I didn’t want to glue it in place, so I sewed it in place. I ran a needle and thread through the tube and around the drain pipe and tied it off. I can cut it off if I need to but it’s strong enough to keep it from falling off.  I haven’t had many leaks, I used gorilla glue around the drippers, so it expanded and stopped any potential leaks.

I originally drilled little holes in the caps and kept them on the bottles, but they clogged really easily. If a hydroton pebble fell out of the basket, if roots grew down into the cap, if dust or dirt accumulated in the cap. So I’ve thrown away all the caps and just leave the bottles open.

Finally

So, ultimately, I love my Window Farm. All of my friends and family think it’s cool, it’s like a conversation piece. Everyone is really interested and curious, plus the fresh herbs are so handy. While Everyone I know seems really intrigued, no one else has made one. Which kinda surprised me, I thought everyone I knew would want to have a window farm.  Maybe it’s because my husband and I are such avid DIYers?

Air speed, water holdup and bottom reservoir ideas for the T-joint system

12:38 am in Being a good member of this community, Education, energy consumption, Help the project by testing this, How-Tos, R&D-I-Y by Brian White

I did a little video today about lowering the airspeed through to windowfarm to vary (and sometimes increase!) the rate of airlift.  Depending on your tubes the rate can be quite slow and still give you good pumping. Check it out because I think it can help people to understand a bit better and to get things right first time.
Anyway here are some pictures that I took out of the video.

2 outlet air flow regulator valve

This is a little aquarium valve and bottom pic shows the adjustment knobs

You can either use it to regulate air to 2 t joints or just leave one open to the windowfarm and have the other one just a bit open to let some of the air escape.

Below is a head for connecting a tube under the reservoir. You might need a bit of gauze or window bug screen in the bottom to stop crud getting into the tubes.

Head for watering plants. Snip off the top and use the "neck" to attach tube

And you also can use this thing for aquariums as a bottom reservoir.

Aquarium attachment for tubing

And finally I am going to show you a pic of the bubble in the tubing.

plug of water

If you reduce the airflow into the t-joint and into the tube, sometimes the water flow increases. This is because the type of flow changes from churn flow to plug flow.

Plug flow can be quite slow sometimes. As the plugs of water rise, it changes from many short ones to a few long ones.

Watch the video to get more information.

Thanks Brian

“Office” Hydroponic System

10:43 am in Featured Post, Projects in Process by Tim

A co-worker and I set up a system at work at my cubicle. We used 1.5 liter plastic Coca-Cola bottles. They were first wrapped with black electrical tape and then aluminum ducting tape to keep the light from the roots.

As far as the air lift system, I purchased a $6 air pump from Walmart. The  air line setup that we came up with does not need any special parts or fittings other than a “T” and a valve.

All of these items I had lying around and so far have only spent $6! I will update later on the progress and what else we used/added.

Our other co-workers have stopped by to look at our setup and have wondered what it is. We’ll keep them guessing. ;)

Will this airlift configuration work?

1:16 pm in Uncategorized by shekel

I’m planning on using 1/2 inch ID tubing for an airlift and an aquarium pump providing 2.3 PSI through a T joint. Is this going to be enough to lift water to about ceiling height? Are there any equations or rules of thumb for this? I couldn’t find a required PSI anywhere.

Setting up my windowfarm… finally!

I have set up the 4 bottles, and now I’m working on my airlift. I’m trying to do the T version instead of the air needles. But I’m having trouble getting the air to lift the water and not escape through what should be the water intake tube.

Any advice for this system? I’m going to go and cut a longer piece of tube and see if that makes a difference.

Thanks,

Melissa

So the longer tube completely helped! There is no air escaping from the system at all. Now my poor tomato plant that was without water all night is getting some.

I purchased the white frame from ikea and it was around 20$. I plan on having 3 or 4 columns with a string of lights in between the columns. This frame will allow me to move the window farm around and close my blinds at night. I’m going to raise it up to window height once it’s all installed.

So my tomato is definately looking good! http://www.flickr.com/photos/58467192@N06/5379181542/in/photostream/
I have also transplanted a broccoli plant to the top of the column. http://www.flickr.com/photos/58467192@N06/5379182328/in/photostream/
My seedlings are starting to sprout! http://www.flickr.com/photos/58467192@N06/5378589329

I made another change to my system… I zip tied the coil of tube in the water so it is easier to remove and install. http://www.flickr.com/photos/58467192@N06/5379179122

Also, nutrients were added to the solution. I added part 1 and part 2 of the general nutrients, and I also added some “maximum plantroids” because it says:

“Plantroids Super-Vitamin Thrive Enhancer stimulates plant branching, increases photosynthesis and cell division. Plantroids also helps reduce stress as well as stimulates root growth”.

Just a warning about CFLs… I dropped one and it smashed into a million tiny shards. Took a while to make sure I got all the little pieces.

Can anyone give me advice on how to put pictures in my post, rather than just links? Thanks.

The basic construction for my first windowfarm is complete since  long. I made an effort to build an airlift. However I encountered some problems which brought me to the point where I decided to boycott the entire airlift concept. It just requires too much specific parts and is a hassle to setup and on top of that it is noisy. Instead I decided to go with a different kind of water-distribution system. The only real issue was finding a pump thats small and has enough pressure to push a water-column to about 4m (12-13ft) while remaining cheap.

I found the solution when I skimmed though my usual computer store, liquid-cooled computer systems! The pumps have excellent specs for this type of projects and the majority of them are submersible as well as being low voltage/wattage which means they can be used in constructing mobile DC-powered systems . The construction is identical to aquarium pumps with impellers so the buildup in nutrient salts shouldn’t pose a problem.

Prices however seems a bit steep since the cheaper brands land at >$45. Which is about the same as the air pumps I’ve found i might add. I plan on circumvent this issue by ordering in bulk from China which should leave me ahttp://www.youtube.com/watch?v=UWPLr0Selh8t about >$20/unit. Only issue being I would have to order about 500 units but I’m putting my hopes to free samples.

Also in the progress of building another ebb&flow like system with top drippers. But thats another thing, however it will use the same type of pump.

How can you tell right amount of water?

12:42 pm in Getting Started, questions, Seeking Advice, Version 3.0 Modular Airlift Columns by JBK

So I have a simple version 3 window farm set up in my window. I have the timer that turns on every 15 mins for 15 mins as they say to do in the instructions, but my plants just dont seem to be liking it. How can I tell if I don’t have enough water (the pump isn’t pumping fast enough) or too much water? Can you have too much water?

reservoir style windowfarm

outside_in
I started working on this one several months ago, before the airlift system edged in with it’s sleek design and lower price point, but ended up moving house in the meantime and having to scrap my original plans. Luckily I moved to a place with great windows, so here is my old skool WF.

inside1
J-hooks_closeup
thyme_focus
It’s still in process, I haven’t been able to work out the timers because my pump (QuietOne 3000)  is *too* powerful: it drains the bottom reservoir in about twenty seconds, and the timer I have only works at one minute intervals, minimum. So basically I just turn the pump on for a few seconds three or four times a day, for now that’s fine but I’m in the market for some fat drain pipe, it seems the only way to hold enough water + nutrients so the pump can cycle through a full minute. Plus I want to house the pump inside the reservoir. But you can see the plantings are doing pretty well, I have enough greens for sandwiches and salads a few times each week. Everything was started from seed using Bio Rooters.

more_arugula

Basil seems to love this method, the thyme is growing slowly so I don’t know if that’s a keeper or not.  Spinach is a bit leggy, but butter lettuce, frisee and arugula are doing fantastically well. I’m hoping to figure out the lighting situation come autumn so I can have green stuff growing all year ’round.

frisee
butterlettuce1
I started with drippers that were billed as 0.5 gallons/hour but they clogged all the time so I switched to 1 gallon/hour and they work great, haven’t stopped up yet.

There were enough leftover parts to get a good start on an airlift system, so I’m going to try some sungold tomatoes and more basil, radicchio, fennel for its purtyness, some vining nasturtiums and maybe even strawberries, since I am very impressed by the intrepid berry growers here on the site. I’m working on an integrated tubing/support and if it works i’ll post the evidence.

I had problems with my account and could not figure out how post for several months, so all the step-by-step problem solving I had planned to post all along has been superseded by all y’all but thanks for everyone’s help. This has been an incredibly fun and rewarding obsession, and I’m getting to know the folks at the hardware store really well (yo, parkrose!).
