I’m new so I thought I’d share my window farm with you. Down here we don’t have the same brand of water as recommended so I substituted with 1 liter bottles (Alpina by Coca-Cola). They are just barely the right size to hold 3.5in net cups so I added some paper clips to help hold the nets in place, those are the colored wires you see. They’re also shorter so I can add more bottles to the column. I’m currently at 5 bottles.
After playing around with the plumbing I’m getting about 100ml of water every 5 minutes. I run the pump for 5 minutes every three hours. It seems to get the substrate good and wet without drying out in between. I’m watching the garden to see if I can reduce the number of waterings.
Anyhow, I’m happy to have found this niche on the web!
See you around!
