LED lettuce raft experiment

So I fashioned up a quick and dirty raft and LED system to give it a go. Obviously from the pictures you'll see it also get some morning sun. these shots were taken when the plants were maybe a week or two old and basically show the set up.

I'm using DNF nutes(I had them laying around) starting at about 475ppm. LED stay on 24/7. they are normally 1"=2" above the netpots.



The overview. lots of sun in this picture.



the LEDs are close. this one is older, you can't even see the lettuce sprouts yet.



here are the plants at about 1-2 weeks. I planted anywhere from 3-5 plants per 2" pot.

Now the plants have leaves that are anywhere from 3"-6" long and basically fill the raft area.

They are grand rapids lettuce if anybody is interested.

I'll post some more pictures hopefully this evening.

Questions, comments, criticisms? let'm fly.
