Hi all, and especially people in the Netherlands, I have a question, do any of you know where to get the net pots? I’ve tried the boeren bond, gamma, praxis and even the growsjop and a specialist in hydrophonics nearby (according to the hydrophonics specialist the net pots are outdated) so if any of you [...]

Windowfarm Friends, We plan on helping out spreading the WindowFarm idea through Colorado. By hopefully sometime be able to set up some time to traveling to elementary, middle, and high schools and presenting our WindowFarm project we made from scratch. Using tools that anyone can buy from a local store and such. In order to do this we have created [...]

  This is my setup, after reading everything I could find on window farms.  I can’t get water to flow up the tube.  Would appreciate any suggestions.  I’m using 3/8″OD tubing.  Out of the picture are 4 bottles.  Very perplexing!

We are an after school class called Science Extaviganza. There are 5th through 8th graders in the class. What we are making is called a window garden. Some of the things that were hard were cutting the correct size and shapes in the bottles. But the things that were easy were putting duck tape on [...]

I came here just in the right time to see cool mods like the t-valve technique (thanks @gaiatechnician), and the way of splitting airlift (credits goes to @kenokazaki) allowing two columns to be watered using only one reservoir and airlift.

I have a three tier Windowfarm in my window. All three plants were grown from seeds placed in recycled tree-bark material in the center of the netcup/hydroton. At the top, I’m growing Peas. In the middle, Jalepenos, and on the bottom, Lettuce. They were all doing well until there was a day when the heat [...]

A quick question with, I am sure, no quick answer. I am building a top reservior system. A 23 watt water pump, on a timer, gets the water to the top of the resevoir, and gravity feeds it down. Simple! But what if a pipe were to disconnect, leak, or water to leave the system [...]

I have a pH of about 5.0 in my reservoir, and I believe the optimal level is somewhat higher (5.5-6.5?). So my question is: what substances do you use to raise the pH? I was thinking of using baking soda – does anyone have any experiences with sodium bicarbonate?   Cheers, Joel
