Looks good to me. I might have done a couple things different, but wouldn't everybody? That ought to do just fine.

Until roots come out of the rockwool, you'll want to have the water touch the RW, oh I don't know, a couple times per day. Once you have good roots, I would not have the water touch the RW, but some of the Hydroton. I would use a double layer of trash bags over the res instead of one.

Good luck. Looking forward to harvest day. Please send pictures along the way.
