How neat to see Little Green Girl a member of the Green Roof Growers blogging team teaching her friends about making recycled soda bottle SIPs (sub-irrigated planters).
She has learned some good stuff from her mom Debbie and Heidi Hough, one of the founders of the blog. Yeah team!
Debbie made this very helpful diagram showing how to make soda bottle SIPs (click on it for a larger view).
It's a minor point but I hook the wicking strips (one u-shape going up and one u-shape going down, like chain links). The wick is probably a little more secure that way. There are a number of variants in making these planters. One of these days, we'll have a PDF showing all of them.
There should be one or more of these planters in every home and classroom in America. Soda bottle SIPS teach good plant science and making them is a great example of recycling, or up-cycling or repurposing as some prefer. Install them inside cachepots (including traditional clay pots) for a more decorative look if you like.
Your houseplants will love the consistent water and oxygen supply provided by SIPs. Add adequate light and they will be in plant heaven instead of the other place where so many houseplants meet their end.
