Besides my fungus gnat problem (http://our.windowfarms.org/2011/01/04/borer-type-bugs-in-my-peas/), my second WF is doing well. We have been picking lettuce leaves off around the edges to eat. The lettuce has two plants in it now. At first I sprouted about 5 and have thinned it down to two. I never like thinning plants out. I know if this was in dirt outside I would have thinned to just the one. I just wonder since there should be less competition for the nutrients, how many plants can you get away with in each net pot?
The first pea is almost ready to be picked and more are on the way. The pea is on the bottom and has three plants in it. I have added dowls through the bottles to form a trellis. Since it was on the bottom, the root have traveled down into the resevoir and it has turned itself into a deep water culture. Since I had an extra port on the air pump, I added an aeration stone into the resevoir to give it some more oxygen.
A good question here is which plants naturally have short roots and which prefer longer roots. I wonder what would have happened if the lettuce and pea were reversed…
Here are some more pictures of sprouting the seeds. I sprouted them directly in the rockwool in a makeshift terrarium and then moved them into the WF when they were big enough.
