Here is what I have done so far. I have to do a little more to it. and I have it set up to where i can expand it to 3 tubes later if I decide to. I will have to do some more work to the plumbing side to add more to it, but that isnt a big deal with all the extra PVC I have laying around right now.
Inside of the 4x4 post is a long piece of 1/2" pvc I havent finished with yet. It will be fixed at the top back corner of the 4x4 to let me put small holes in to spray on the net cups that I will be putting in there (have to wait for them to get here to make the holes). The purpose of letting it spray on them is to let me put plants that dont have roots that will hang down yet.
Hopefully the net cups will be here soon. I have them ordered and should hopefully be here next week if I am lucky. My lettuce
seeds are already set up to germinate (I hope they all do). I set them up today in hopes that everything will be here on time to let me put them into the system.
I also have to put up the support for the
lights I will be putting up. I am going to do 4 T8s. with 6500k
bulbs. That should be plenty with the system sitting next to a south pacing 6ft window.
