I've purchased some Rain Science grow bags this year. I love them so far. I believe they are built to last many, many years. I don't have an issue with drying out as I have them set up on the hybrid rain gutter grow system. A bit pricey but I think they are worth it. Currently have 8 bags but plan to replace all my bags next year with the Rain Science bags.
