Tell us about yourself!
Yes, good idea. Other options are to:-use UV resistant planters (more expensive and difficult to find in large sizes)-make your own out of concrete-use terracotta planters, block the drainage holes with epoxy, drill overflow hole. Terracotta is the version I'm using now. I don't use gravel, but make a reservoir at the bottom by using old pallets to make a frame, and use old cotton t-shirts as a wicking material.In the photos you can see, a circular terracotta pot in process, as well as a completed rectangular terracotta pot and some older UV proof plastic pots. All with the same sub-irrigation system.
As others have said, you are going to have problems with those plastic bins. I did exactly the same thing, and they died within a year or so. You may also have problems with the plastics leaching out horrible chemicals into your plants. Not a huge issue if they are not edible.. but if they are.I've now replaced all my plastic planters with ceramic and wood ones (the only plastic I've used is the water pipe). But you've inspired me, I'll add an instructable!
Pleasure. Not my idea originally but one worth sharing.
Very nice. Im a fan of diy sub irrigation which might be a slightly better method. Or might not be! Yiu can find my description here:http://ferguskane.com/blogs/en/high-altitude-gardening-sipping/
