My First Airlift Window Farm and Limp Lettuce Seedlings

3:53 pm in Uncategorized by Tony Reyes

Pictures, video, and material list are below.  I just transferred eight lettuce seedlings to my first hydroponic window farm.  They are looking a bit limp though.  The leaves seem healthy but the central stem seems a bit limp.  They were in this state before the transfer.  I started them in General Hydroponics rapid rooter cylinders for two weeks before transferring them.  Do they look normal for this age in the pictures below?  I focused on minimizing the amount of plastic in the system and used copper piping and glazed claypots where practical.  A youtube video describing my windowfarm can be seen here:  http://youtu.be/9mVqVwzEVJ8  (video was still uploading when I posted this so check back in a bit if not yet ready.) I’m using General Hydroponics Flora 3 part nutrients in a 1-1-1 tsp per gallon ratio for general vegetative growth.  During the seedling stage it was a less concentrated mix with 1/8tsp per gallon instead of 1tsp per gallon of each nutrient.

The materials for the build are listed below including prices with tax (a couple of scrap items I missed in the list are a 4′ piece of 3/4″ EMT electrical conduit and 8′ of yellow Nylon string):
