Very exciting- A few years ago there was almost no news on SIP's- now people are coming up with improvements seems like every day. Larry Hall is one of those folks- he came up with a watering method that doesn't use a bucket, (Saving more buckets for growing!) The cool thing about this design is I could see using it straight from one of my rain barrels to the gutter for irrigating. And since I will probably replace the plastic rain gutters on the garage this year, gives me an idea what to do with the old plastic rain gutters!
Here is what you need to build Larry Hall's self filling Rain Gutter Grow System!
2- 10 ft treated 2x4's
1- 10 ft rain gutter and 2 end caps.
a mini float valve to regulate water
3 inch net cups (they are cheap!)
