This weekend I started building a WindowFarm with my brother. Building it together is actually his Channukah present (just don’t ask which year’s). We used the ‘mini’ version 2 instructions that will yield a single column WindowFarm holding three planters. The instructions are not the best, but they’re totally sufficient if you’re willing to wing things a bit.
I didn’t start taking pictures until we were already underway.
We cut holes in the bottom of each water bottle so they can stack and drain into each other. We also cut holes in the side to insert the net cups (and so the plants have room to grow). The instructions specify that you should use Poland Springs 1.5 liter ‘eco design’ bottles. They don’t really explain why, but the reason is that they get narrower in the middle and that holds the net cups nicely in place. We used another brand of water bottles that had a similar narrowing in the center.
Then we started cutting tubing for the air lift.
We didn’t buy all the different types of tubing the instructions call for so we had to improvise to get the air pump needles attached to the tubing. Liberal amounts of teflon tape were used, followed by testing for air leaks in a nearby cup of water.
The aquarium pump has two outlets. Each one gets a tube with an air pump needle. These were inserted into holes at the bottom of the air lift tube. This will carry water to the top of the WindowFarm which will drip through each planter and back into the reservoir at the bottom.
Sarah and her furry assistant taped up the bottoms of the bottles.
Then they got all artsy on ’em.
