Those are a bit pricey, but they did get me thinking about how I could maybe fabricate something. Would also be interested in hearing from someone outside of CA - colder climate, that is - to see how the strawberries stand up over the winter months.

I was reading and just posted to another thread about something called "the dark garden", a homemade vertical-type scenario. The creator's user name on this site is georgeiii. Scroll to some of the most recent posts to have it presented a bit clearer, the first few posts are a bit confusing, but georgeiii added numerous pics toward the bottom of the thread and another poster named grvtykllr cleared up the explanation pretty well. http://forums2.gardenweb.com/forums/load/contain/msg0300042724120.html?10811

Anyone interested in this kind of rig need to visit the folks at Verti-Gro. They've been here in biz in florida for eons and are very nice folks to do business with. Also way cheaper. 20 planters for $80 vs 6 for $70 of the Agro-Towers. You can buy all the rest of the pieces and parts at your Blue or Orange Box Store hell.
