This is my first blog. Hope I’m doing it right!

I had difficulties understanding how the air tubes connected to the lift tube. The DIY assembly instructions were not very clear to me.

I finally figured it out and have included a hand drawing of it. So far it’s working fine. I would recommend installing the little muffler thing to cut down on noise though.

Please don’t laugh at my drawing… ! 

I hope windowfarms folks will add a better picture to the instructions … it almost made me give up because I couldn’t see how to connect all the tubing.

Is there any interest in a design for a simple 5-10-15 minute/hour pump timer?  I can put together a little how-to (or even a kit with a printed circuit board) if anyone else is interested.

Just a simple AC plug that turns on once per hour for a user selectable time interval, lots cheaper/simpler than a  programmable timer (ie Intermatic) with the display and keypad. Minimalist is what I’m offering.

We are pleased to announce the V3.0 release of the windowfarms community’s latest windowfarm design, the V3.0, the Modular Airlift Multicolumn Array, or MAMA!

• quieter
• easier to set up
• more elegant, but still do-able with all recycled water bottles
• more plants for less electrical input (up to 32 plants on one air pump if you do Rama’s double plant mod)
• modular, meaning you can supply proper nutrients to vegetative, fruiting, and flowering plants all in one system.

No more airlift issues with the new tubes. And we have finally achieved some serious height!! Achieving height means you can grow more plants with the same pump so it is way more efficient in terms of the amount of nutritional calories per fossil fuel calorie used in powering the pump. This design described in the free how to is basically the same as the new Classic kit.

If you are a total beginner and not the handiest person in town, we suggest you start with the Version 2.0 airlift system, or consider buying a kit (kit cost comes out about the same as buying all the materials yourself anyway, but we source just the right parts responsibly and the little margin between supports the cost to run the project!!).

We decided to release this as a participatory web guide that captures ideas, questions, sketches, discussion, & issues for R&D-I-Y while you build. This new functionality is still in it’s “beta” testing phase & we are working on integrating it with this site still.

Thank you to all contributors to the our.windowfarms.org site & BIG PROPS to @ramajames, @Hardwarejunkie,  @samenrahmen, and other users who have contributed so much to the art of windowfarming.

We are almost there on kits, Folks. We would love your input on a couple of things.

For more about why we are making kits, read this.

Here’s how kits are looking.

You will choose between a 2-column or 4-column windowfarm. You WILL have to be able to screw at least 4 screws into your upper window sill. The bottom bottle of each strand will be the reservoir.
We will probably produce the first batch by hand ourselves here in the Brooklyn shop but the next batches may be handled by an awesome little organization that hires the disabled just North of the city.

Get a sneak peek of the one we have in Brooklyn headquarters here.

Major points up for debate:
1) To give you the bottles or ask you to supply your own. If you supply your own, you need to drill through the tough end very precisely and this can be a dangerous task with a drill or a red hot cylinder. However, sourcing the bottles and getting them to you is very expensive on our end. What do you say? Would you be willing to pay a premium to not have to find, drill, cut, and paint your own bottles?

2) To include the pump or not. The petco pump is the best one we have found and it comes with air valves. However, some people have found that their pumps are duds. Having to deal with Petco’s duds will be a big burden on us that will take away from our mission work. We’d prefer to simply have a button while you are buying you kit that you press to order your pump from Petco separately. Is this a deal killer?

3) Lights. Almost everyone really needs them but no one ever wants to get lights. That is, until after they start raising their little baby plants and the plants come out looking leggy/scrawny. You can pump them full of nutrients but if they don’t have enough light to process the nutrients through photosynthesis, it is very sad =<. Anyway, I'm thinking we will sell lights as a separate kit. You would buy individual strands. Sound good?

Also, if you have a great business mind, experience with this kind of production setup, and some time to volunteer, we would love to hear from you. Send me a message by finding Britta under members.

Another suggestion for an income stream to support the Windowfarms Project mission that would simultaneously provide local jobs and green collar training is a mobile installation crew.

I have gotten messages from at least ten individuals- including one senior citizen in Manhattan- requesting such a service.

We already have one awesome local highschool kid on the windowfarms core team, Roy.

I would love to give Roy and other kids like him a job going around the city on bikes with baskets to come help you install your windowfarm properly and to make sure you are set up well to maintain it.

Perhaps you would buy a kit and then choose to add on the additional service of an installation.

Do you know how we could fund the startup costs for this new piece of the venture and train a bunch of kids ASAP? If so, please shoot me a message.

What pricing seems reasonable to you guys? Should we price it similarly to a visit by a plumber?

Why are we making kits if this is an opensource hardware project?

Building your own windowfarm is always an option and enabling anyone who has more time than money to do this is the whole point. That is the “charitable” cause we are working for here at Windowfarms headquarters.

However, we are also trying to get as many people as possible to have windowfarms so we can do collective research on how to best grow plants under the local conditions of our homes. This is our secondary research mission. NASA is researching how to grow plants in the space station and we are researching how to grow plants in our apartment windowfarms– both unlikely but potentially viable venues for veggie plants given a little help from us humans.

A lot of people have asked us, the core team, to just make kits. Not everyone is willing to be a hardware hacker and lots of people with valuable skills to add to the project (foodies, gardeners, teachers, parents) just say they are not handy enough to build their own. We want to get these people on board so the hackers can learn from the gardeners and we all build new skills!

Finally, this will be a source of income for the project. Believe it or not, it takes a lot of time and money to run the windowfarms project and frankly, I’m going broke. We used the funding we raised on Kickstarter earlier this year to set up a shop, improve the fundamental infrastructure of the website for higher traffic use, and to start testing components for kits.

I would like this to be a source of local green jobs for some of the dedicated volunteers whose time and brilliance have made this project possible. If we cannot pay some of them for their time, they need to move on to other work soon and we will lose their valuable accumulated knowledge. Instead, I hope we can bring them on in a more permanent capacity to have them help me train a new workforce of NYC local kids who will then be ready for the coming greencollar market in NY.

If you have some great business experience, legal acumen, good connections, and/or some time to volunteer to help make this mission happen, please send me a message.

Kits will be a lot like this.
