Great, thanks Vlad. Not that much more to go deeper really. And the good part is it doesn't tax sump capacity like flood and drain does. I'll certainly go to 10" then.
Hi Jim, so realistically your looking at 5.5" to 6" (or so) of water. If at all possible go deeper. The more water volume the better IMO. Anything to help stabilize temps (both arm and cool) is a good thing in my book, as well as giving the root mass some more room. Not that you won't necessarily be able to grow lettuce in 6" of water or anything, because you can...but if you are able to go deeper (like 8-10" of water) that might be (far) better. :)
Vlad, I am about to add my 4' x 12' raft bed. I'm making a platform like my first one so I can go either way in the future but want to give the raft a try for the next year at least. My question is how deep (high) do you suggest I make the liner walls? I was going for 8" (7.25") 2x8s but thought I would ask my raft guru buddy first. The platform will be at about a foot high under it for a more convenient work height and I will have access from both sides. Not that that has anything to do with my question, well maybe from a weight stand point it does:-)
Well it's about time we saw more of your GH op. Nice.
